lesions constitutes an important topic in the so-called “border-land”
between medicine and surgery, where views and advice regarding
prognosis and treatment will depend on the experience and the training
of the medical attendant. Surgeons now recognize, and physicians are
being gradually converted to their view, that _gallstone disease
is essentially a surgical disease_, _i. e._, one to be combated by
surgical intervention. While it is not to be gainsaid that many
patients live and die with gallstones who are never conscious of
their presence, and while others who have had serious attacks live
to die of some other disease, nevertheless the general statement may
be boldly made and easily defended, that _when the disease is well
marked and when patients suffer more or less constantly from it the
only successful method of treatment is the surgical_, and that, in
other words, operation offers the only prospect of permanent relief.
Regarding its associated dangers it may be said that _danger comes
from delay rather than from operation_, and that here, as with many
other conditions, patients often wait too long, partly from lack of
proper advice, partly from timidity, and that a septic and moribund
patient, allowed to become so for lack of earlier application of the
resources of surgery, is a reflection on the one who waits rather than
on the surgeon, who, endeavoring to save, still unfortunately loses his
patient.
This is not the place to discuss non-operative measures--_i. e._,
medicinal and dietetic treatment--valuable as they may be in certain
cases. Most of the drugs which are supposed to be effective in their
power of solution of gallstones or of facilitating their escape are
disappointing, and at best are vague and uncertain in their action.
The hydrotherapeutic treatment, such as carried out, for instance, at
Carlsbad, will do good in many cases, especially for those who have
been indulgent in their appetites and careless in their habits. Cases
of any description not too far advanced would be benefited by a careful
regimen of this character, but that Carlsbad or any other waters
will certainly cure cholelithiasis is now absolutely disproved. As a
preparation for operation a sojourn at some such place may be advised;
as a substitute for it, never. Large doses of glycerin (50 to 150 Cc.)
often temporarily relieve the pain of biliary colic.
In general, then, it may be said that cases which give a history of
recurring attacks of biliary colic, with or without recurrent jaundice,
and with those varied concomitant symptoms which are usually grouped
under the term “indigestion,” in which there is definite tenderness
over the region of the gall-bladder, with or without muscle spasm,
and with the other referred pains so often present in this condition,
should be regarded as legitimately surgical, where operation is more
than justifiable and usually decidedly advisable, even too often
imperative. The same is true of those cases of distended gall-bladder
with obstruction of the duct where perhaps no calculi are present, but
where the patient suffers in much the same way as though they were
present. _Biliary drainage is equally called for, and the presence or
absence of calculi is but a minor feature_ upon which too much stress
should not be laid nor too much disappointment expressed if they be not
found.
Many cases of chronic cholelithiasis have become more or less toxemic,
as well as cholemic. It is a well-recognized fact that cholemic
patients are more likely to cause inconvenience to the surgeon from
free hemorrhage or persistent oozing, because of the slowness with
which coagulation of their blood takes place. When time is afforded for
preparation it is of great value in these cases to administer calcium
chloride, of which several doses may be given each day, in considerable
water, the former varying in amount from 1 to 2 Gm. When time suffices,
too, it is always of value to prepare these patients for the operation
by measures already discussed, improving their elimination, reducing
the degree of their toxemia, and fortifying their circulatory systems
by well-known measures. The value of such preparation is perhaps more
apparent in such instances than in most others. On the other hand, many
cases calling for operation are almost as imperative as those of acute
appendicitis, where every hour’s delay is to the disadvantage of the
individual. The operations which are practised upon the biliary tract
will all be discussed together in a section by themselves.
TUMORS OF THE GALL-BLADDER.
This expression refers rather to actual neoplasms of the gall-bladder
itself than to distention of the sac by which an intra-abdominal tumor
may be formed. The latter subject may be dismissed with the mere
statement that the gall-bladder may become distended with bile, with
mucus, with pus, with concretions, or with the products of such disease
as echinococcus, actinomycosis, etc. In this way it may be so much
enlarged as to be easily felt through the abdominal walls or to be even
mistaken for other conditions. In the latter case it may have to be
differentiated between such a condition and a movable right kidney, a
tumor of the kidney itself or of its capsule, as well as from tumors of
the stomach, especially the pylorus, of the liver, or of the intestine
and from the enlargement of the right lobe which often accompanies
cholelithiasis, or from fecal impaction. It would be best to abstain
from the use of the aspirating needle in these cases, as more harm
might be done by the escape into the abdomen of deleterious fluid
than would be atoned for by the information which the procedure would
afford. Even when the abdomen is open the gall-bladder should rarely
be punctured in this manner, unless one is prepared at the same time
to open it and drain. In other words, there is less risk about a small
exploratory incision than in puncture.
Nearly all varieties of _malignant_ and many of _benign_ tumors have
been reported as occurring in this location. It will be sufficient in
this place, however, to say that _cancer_ of the gall-bladder, which,
of course, may extend in various directions, is by no means an uncommon
affection, and is _usually a complication of gallstones_. In fact, it
may be doubted whether primary cancer of the gall-bladder ever occurs
in the absence of such a source of irritation. These cancers vary in
type between the round-cell and the squamous, most of them, however,
being of the former character. Although Musser has put the percentage
at 65 and Zenker as high as 85 of instances where gallstones are found
within cancerous gall-bladders, it does not follow that the above
statement may not be true regarding their almost universal association
and causal relation, for any gall-bladder found empty at a given
time may at some other time have contained a calculus. This frequent
association is justly among the valid arguments which surgeons may now
use in making a plea for earlier operation, and for making it a more
standard procedure.
_Cancer_ may be suspected in cases of progressive and unintermittent
jaundice, especially when there can be felt in the region of the
gall-bladder a distinct tumor or an enlargement of the liver. Pain
is a frequent but by no means a constant or reliable symptom. As the
disease spreads the adjoining textures will become matted together, and
a low grade of local peritonitis may still further cement them into a
mass which will occupy a considerable portion of the upper part of the
abdomen.
But few cancers of the gall-bladder which are so apparent as to be
recognized without exploration can be considered as still amenable to
surgery, which for them can hold out but little prospect save perhaps a
temporary relief by biliary drainage. It is the cases in their earlier
stages, when the condition is made out by exploration, and by it alone,
which still afford prospects of more or less permanent relief. The
very impossibility of detecting the condition in these earlier stages
without exploration affords one of the strongest arguments for such a
procedure in every vague case of the kind. That cases of this character
are not necessarily hopeless is instanced by an experience of my own,
where on opening the abdomen of a large and fleshy woman I found a
distinctly cancerous gall-bladder containing two large calculi, and
removed the entire mass, with a considerable portion of the surrounding
hepatic tissue, the removal being effected with the actual cautery.
At present date of writing, nearly six years after the operation, the
patient is apparently perfectly well and doing her own housework.
OPERATIONS UPON THE GALL-BLADDER AND BILIARY PASSAGES.
The small area included under the above title has been made the field
for a variety of operations, dignified with formidable names, the
entire list of which might be made quite long. In order to simplify
their arrangement and illustrate their purposes they may be referred
to as (1) operations upon the _gall-bladder proper_; (2) those _upon
the ducts_; and (3) the more complicated operations upon one or
both of these in connection with some other part of the intestinal
tract; or, to catalogue them somewhat definitely, the operations upon
the gall-bladder include _cholecystotomy_, _cholecystostomy_, and
_cholecystectomy_, according as the surgeon opens the gall-bladder
and closes it, makes a more or less permanent opening, or completely
removes it. Again, upon the _ducts_ he may make _cholangiotomy_ or
_cholangiostomy_, or, using their practically equivalent synonyms,
_choledochotomy_ or _choledochostomy_, these terms referring to
operations upon the cystic and the common ducts; while when similar
procedures are applied to the hepatic duct they have been spoken of
as _hepaticotomy_ and _hepaticostomy_. _Cholecystenterostomy_ refers
to an anastomosis between the gall-bladder and the upper bowel, while
when this is effected between the common duct and the bowel it is
referred to as _choledochenterostomy_. When a stone lies partly in the
common duct and partly within the wall of the duodenum, and it becomes
necessary to incise the latter, it may be spoken of as _duodenotomy_.
The operation of merely crushing biliary calculi, hoping that the
fragments will be passed on with the flow of bile, and spoken of as
_cholelithotrity_, is now almost abandoned, and the term has historical
rather than present value.
To even attempt to epitomize directions for these various operations
into space available here would be impossible, for large volumes have
been devoted to this subject alone. The main thing for the student
and the junior practitioner is to appreciate the indications for
their performance, at which he should certainly have assisted before
attempting to perform them himself. General directions, however, may
be given as follows, the usual preparations having been made both
of the patient and the environment: A woman who has borne children
and who has, in consequence, relaxed abdominal walls, makes a more
favorable subject for operation than a muscular man whose abdominal
muscles cannot be relaxed until a profound degree of anesthesia has
been obtained. In many instances exposure is made better by placing
a sandbag behind the region of the liver, especially on the side to
be operated, by which the costal angle is more outlined and the parts
pushed forward.
A preliminary incision should be made of, say, three inches in
length, and is best placed a little to the inner side of the outer
border of the rectus, whose fibers are separated and its tendinous
intersection divided. This incision may be extended upward and curved
toward the middle line, as recommended by Bevan, or downward, as the
exigencies of the case may require. The beginner especially should
provide himself with sufficient space for manipulation. The posterior
sheath of the rectus and the peritoneum are best divided together.
Sufficient opening being thus made, a finger may be inserted for the
purpose of exploration. In the presence of adhesions, and especially
in acute cases in which pus is likely to be present, this should be
done with great caution. When no adhesions are present gauze pads may
be inserted and so disposed as to permit exposure to view of the lower
surfaces of the liver. The operator should be prepared for any and all
conditions--one of dense adhesions or their complete absence, as well
as for cobweb-like adhesions which surround foci of infected exudate
or of pus. The more reason he may have for suspecting the presence of
pus the more carefully should the region be walled off with protective
gauze. Adhesions are most likely to form between the omentum and
the colon, in front and below, and with the stomach, duodenum, and
colon below and behind. Those who have had experience with abdominal
operations will appreciate whether these adhesions are recent and
likely to cover purulent foci, or old, and will proceed accordingly.
Occasionally tissues will be so matted that even an experienced
operator will scarcely be able to differentiate them.
The endeavor should be, if possible, to expose the gall-bladder itself,
both to touch and sight, in order that after orientation concerning its
actual condition its duct may be followed into the common duct, and
this into the intestine. This is sometimes an exceedingly easy matter,
and again impossible. The presence or absence of pus will of itself
indicate what should be done. When, for instance, the gall-bladder is
found black or partly gangrenous the surgeon will content himself
with doing the least possible amount of separating, endeavoring rather
to provide the widest outlet for drainage. It might be better to make
simply a small opening and permit the escape of fetid débris, and to
postpone until a later day further attempt to remove the calculus,
which presumably has produced the difficulty. Local indications, then,
should be considered along with the general condition of the patient.
The lower surface of the liver will afford the guide to the location
of the gall-bladder, and when the latter is nearly obliterated its
discovery sometimes taxes the resources of the surgeon. When not
contracted it is usually easily exposed, and so far freed that it
may be even drawn up into the wound. After having thus isolated and
perhaps secured it, it must be decided by further exploration how it
shall be treated. It is of great importance to liberate the ducts from
surrounding adhesions.
=Cholecystotomy.=--Cholecystotomy, sometimes fallaciously spoken of
as ideal, consists in simply opening the gall-bladder, emptying it of
calculi or other contents through a small incision, and closing this by
sutures. The operation is ideal in but one way, but conditions which
permit it rarely justify it, for any gall-bladder so diseased as to
call for operation needs either removal or drainage.
=Cholecystostomy.=--Cholecystostomy includes provision for drainage
over a considerable length of time. A distended gall-bladder which
permits of easy manipulation and isolation may be sufficiently long and
large to justify uniting its surface to the peritoneum and deep margins
of the wound, in such a way as to permit discharge of its contents
through the latter. The old method was to unite it to the skin. This
should never be done, as fistulas thus resulting are more likely to
be permanent. If the gall-bladder be thus affixed to the parietal
peritoneum the better way is to insert a drain, its arrangement being
left somewhat to the choice of the operator. For my own part I prefer
a rubber tube, not too flexible, inserted two or three inches into
the gall-bladder, through a small opening closed around it, with
invaginated edges, by a purse-string suture of chromic gut, by which it
is intended to prevent leakage into the abdominal cavity. By another
suture of common gut the tube may be so fixed as to avoid danger of
being lost in either direction. If the gall-bladder be sufficiently
long to permit additional fixation to the depths of the abdominal wound
the operation is made still more ideal; but in the case of a short and
contracted cavity the tube may be left to follow it into the abdominal
recesses. Within forty-eight hours the exudate which has been thrown
out around it will have become sufficiently organized and well ordered
to form a canal in which the tube shall rest, and which shall serve
later as a conduit to conduct bile to the surface after removal of the
tube itself. Into such a tube, after the application of the dressings,
may be conducted another more flexible tube, whose upper end shall
connect with a receptacle of some kind, which may later be a bottle
held within the dressing, to receive the discharge, and thus avoid
soiling.
This operation has been done occasionally in two sittings, the
gall-bladder being brought into the upper part of the wound and
fastened to the peritoneum by sutures, which should not perforate its
walls, as that leakage would occur which the method is intended to
avoid. After waiting a day or two for adhesions to form the cavity is
then opened with a knife or scissors and drainage thus accomplished.
This method has been practically abandoned, for the reason that it
permits no digital exploration by combined manipulation.
=Cholecystectomy.=--Cholecystectomy includes the removal of the whole
or the greater part of the gall-bladder. It has already been stated
that this is a _reservoir_, convenient and advantageous, but not needed
in a way, and not essential to life. It figures as a superfluous
organ, then, similar to the appendix, and there is no reason why, when
diseased and troublesome, it should not be _extirpated_. Its removal
will sometimes be a matter of choice, and at other times a necessity.
The former is the case when the surrounding conditions lend themselves
to its dissection from the lower surface of the liver without too
much violence to other tissues; the latter when it is involved in
malignant processes or when its interior is seriously infected. An
incomplete method of treating the gall-bladder under the latter
circumstances might include the _scraping or removal of its thickened
mucosa_, without removing the entire thickness of its structure. In
this case, however, drainage would be required. That the gall-bladder
may be completely separated and thus isolated, with comfort and
speed, requires that its wall be sufficiently strong to stand the
ordinary manipulation. This may not be true of the perfectly normal
gall-bladder, but in such case no one would think of removing it,
whereas the cyst, which is diseased sufficiently to justify removal,
will usually permit of the necessary manipulation. Even if somewhat
torn in the process the procedure may be effected without much added
difficulty. This procedure consists essentially in separation of the
overlying peritoneum and enucleation of the gall-bladder from its bed
or the depression in the liver in which it lies, which, as already
indicated, may be narrow or wide and deep. Actual separation from liver
tissue will be followed by oozing and at least two or three vessels
in the surrounding structures and at the neck of the gall-bladder
will require to be secured. Removal should not be attempted in cases
which do not permit of it, but may be practised in those cases not
too infected, when after emptying the sac (full of calculi, for
instance) it can still be established with the probe that the common
duct is patulous. These are ideal cases for such complete work. The
gall-bladder having thus been isolated down to its cystic termination,
the surgeon proceeds much as though it were the appendix, by firmly
ligating the duct with chromic gut, guarding against escape of contents
while it is divided on the distal side of the ligature thus applied.
The stump of the duct is then cauterized with pure carbolic, after
which oozing is checked by tamponing for a few moments. It then is
often possible to bring together the peritoneum beneath the torn liver
surface and almost completely cover it anew. The liver tissue will bear
a ligature or suture not too tightly drawn. If the case have been one
otherwise surgically clean, and the operation properly conducted, the
abdominal wound may be closed without drainage. If, however, doubt be
felt a small cigarette or a tubular drain may be placed, to be left
not more than thirty-six hours. Every infected gall-bladder, if not
removed, should be thoroughly cleansed, its interior being mopped with
gauze, preferably with the addition of hydrogen dioxide. An important
step, next to attention to the gall-bladder proper, is to demonstrate
the patency of the ducts. This is done by gently passing a probe,
which should be bent to suit the case, along the duct and into the
intestine. This, of course, cannot be done if calculi are discovered
by manipulation, neither can it always be done when calculi are not
present. Gallstones in the duct can usually be distinguished by the
fingers with which the exploration is made, and failure to thus pass
a probe may be brought about by stricture rather than by calculous
obstruction. The importance of this determination will be seen in
removing the gall-bladder, as to remove it in an obstructed case is to
leave no outlet for bile except into the abdominal cavity, whereas to
fail to drain such a case is to plainly neglect to meet the indication.
[Illustration: FIG. 628

from their investments; ligation of cystic duct and arteries. (After
Kehr.)]
=Cholecystendysis.=--The term cholecystendysis, now almost obsolete,
implies practically a cholecystotomy with drainage, the gall-bladder
having been opened for the purpose of removal of one stone or more and
then united to the abdominal wound.
Of the _operations upon the ducts_ there is something to be said
in addition to the directions already given. Inasmuch as they lie
more deeply they are more difficult of access, and variously shaped
retractors, with walling off the cavity with gauze, are more often
required, while in proportion as deep adhesions have enwrapped the
structures they are made more difficult of exposure. At present
surgeons have less hesitation in leaving duct incisions unclosed than
was formerly felt. It was formerly held that every incision into
a duct should be closed with sutures. It has been later found that
satisfactory results ensue when the end of the drainage tube is left
resting, or even fastened, within the duct opening, the operation being
thus made shorter and simpler and the difficulties of deep suture thus
obviated. As elsewhere noted the common duct may become enormously
_dilated_, and may be almost mistaken for the small intestine. The
passage-way between this duct and the gall-bladder may be so obstructed
that double drainage will be of advantage, or this may be a case where
partial removal of the gall-bladder may be effected, with drainage
of the common duct. Such cases should be judged upon their merits.
The more infectious the existing condition the more is free drainage
demanded. When a stone is impacted in the ampulla of Vater there should
be no hesitation in dividing the walls of the duodenum in order to
extract it. In such a case the duodenum is sutured, but the duct or the
gall-bladder must be drained (Fig. 629).
These deep operations require free incision, several inches in length,
and it will astonish the beginner to see how the liver may be delivered
from the abdominal cavity through such an opening. Much assistance
will here be gained by a large pillow or sandbag placed beneath the
back. Bleeding vessels need to be secured, at least temporarily, with
forceps, and usually with sutures or ligatures _en masse_. The exposed
or torn surfaces of the liver will ooze freely at first, but bleeding
usually ceases with the pressure of a gauze tampon. From the uninflamed
gall-bladder the peritoneum is usually easily separated, with but
trifling hemorrhage. For deep work traction on the middle portion of
the duodenum makes more prominent the junction of this part of the
bowel with the gastrohepatic omentum, at which point the peritoneum may
be incised and separated along the free border of the duodenum until
this portion is free from external peritoneal covering. There will be
exposed here the second portion of the common duct where it lies upon
the pancreas, it being more or less embedded in the latter further
along. When it is necessary to cut away more tissue it is better to
sacrifice a portion of pancreas rather than of duodenum itself. Blunt
dissection alone should be made here. When it is necessary to cut it
will be better to use the thermocautery.
[Illustration: FIG. 629
Removal of gallstone entangled at the papilla. Kocher’s method of
displacing the duodenum: _a_, incision in the paraduodenal peritoneum;
_b_, pancreas; _c_, location of the stone; _d_, duodenum; _e_, sutures
used either for retracting or closing opening in the common duct; _f_,
retroduodenal venous plexus. (Kehr.)]
These various cutting operations have superseded the previous methods
of endeavoring to crush stones within the duct and force the fragments
along by pressure. The Mayos have recommended the use of two fine
parallel sutures, introduced longitudinally into the duct, between
which the incision should be made, and which may be used as tractors,
or subsequently for purposes of closure.
Practically every gall-duct case should be drained with a tube
extending down to the deepest portion of the site of the operation.
This may be done with what has been called a “dressed tube,” made
by surrounding an ordinary rubber drain with a few layers of gauze
and covering this with oiled silk. The lower end of the tube is then
bevelled or trimmed in fish-tail fashion. This may be passed into the
depths, or it may be used for gall-bladder drainage as well.
Of the _anastomotic operations_ there is less heard now than a few
years ago. There are now considered to be but a few conditions which
are not better dealt with by biliary drainage as made above than by any
other method. Occasionally, as, for instance, when the common duct is
strictured or involved in pancreatitis or cancerous deposit, and bile
is backing up into the gall-bladder, it may be of great advantage to
effect an anastomosis between the latter and the bowel. At one time
the colon was used for the purpose, but this prevented the utilization
of the bile in the upper bowel, where it is most needed. Consequently
it should always be made into the upper portion of the bowel, the
duodenum, or one of the upper loops of the jejunum. For this purpose a
small Murphy button is probably still the speediest and best expedient.
This is true also when it seems necessary to drain the common duct
into the bowel, since the field of operation in most cases lies too
deeply to permit of accurate and satisfactory suturing. A further and
more difficult as well as later application of this principle has been
suggested for certain cases of permanent obstruction of the common
and main hepatic ducts. Under these circumstances the operation last
mentioned would be useless and a cholangiostomy would be objectionable,
as it would constitute a permanent fistula. As practised by Kehr and
others this _hepato-cholango-enterostomy_ is performed by removing from
the lower surface of the liver a strip of its tissue about 7 Cm. long
and 2.5 Cm. wide. The hemorrhage is checked with the thermocautery, and
with it an opening is made into the liver, of such a depth that several
of the bile ducts are thus divided and opened. The uppermost loop of
bowel which then can be utilized without tension is opened and sutured
to the margins of liver wound. The method is still on trial, and yet
in at least one successful case it was shown that the liver tissue
tolerated this unavoidable contact with the contents of the upper
abdomen (Fig. 630).
[Illustration: FIG. 630
Demonstrating the technique of anastomosis between the gall-bladder and
the jejunum. (Cordier.)]
=After-management.=--What to do with these cases of biliary drainage
after it has been effected is sometimes a serious problem. No
hard-and-fast rules can be laid down regarding the length of time
during which drainage should be maintained. In instances where the
gall-bladder has been removed the drain should be taken out within
thirty-six hours, but in those cases where a tube has been fastened
into the gall-bladder for so-called permanent drainage the term
“permanent” may be regarded as elastic, and covering a period of from
ten days to perhaps ten weeks. In the majority of instances three weeks
or so of such drainage suffice to meet the original indication. In
cases, however, of chronic pancreatitis a long period of easy outflow
will be demanded, while in rare cases of cancer drainage once thus made
cannot be abandoned.
When the gall-bladder has not been fastened nor allowed to adhere to
the skin, but only to the peritoneum, the fistulas thus made will
usually close and rarely need stimulation. Should, however, the
granulation process by which closure is effected be too sluggish it
may be stimulated by the application of nitrate of silver, either in
solution upon a swab, or in solid form, as when melted into a bead upon
the end of a suitable probe. Firm pressure will also assist in final
closure.
It is not reasonable to expect that after so much intervention, within
the rudely triangular potential cavity occupied by the gall-bladder and
the ducts, adhesions will not form as a part of the reparative process.
In fact it may rather be expected that as it becomes obliterated
adhesion must necessarily follow. In consequence there may result an
agglutination around the gall tract, and into a common mass, of the
liver, the colon, and the pyloric end of the stomach. In spite of these
adhesions bad symptoms rarely ensue, and when discomfort persists it
is usually in those cases in which no stone was found or those in
which stones have been overlooked. Andrews regards such postoperative
adhesions as unavoidable and even desirable, and, having no faith
in any measures to prevent their formation, differs from Morris in
regard to the technique of their subsequent removal. It appearing from
observation and experience that the stomach is the organ which suffers
most by extensive adhesion to the liver, he has proposed to substitute
the colon for the stomach in this necessary union of surfaces, and
would even practise it in old cases after separation of old adhesions.
The operation suggested by Andrews, and which he calls
_cholehepatopexy_, or _colon substitution_, is made with an incision
through the middle line of the right rectus, avoiding any old scar,
long enough to afford plenty of room. The stomach is then carefully
separated from the liver, tearing liver tissue rather than that of
the former, if something must be torn, and checking bleeding by hot
sponges. The pylorus having been exposed the stomach is invaginated
into it in order to demonstrate its patency. The freshly separated
viscera will now fall again into immediate contact unless the
transverse colon be pulled up and held in place between the liver and
the pylorus, this not being so much of a displacement as would appear,
as the bowel is not rotated and does not cross over the stomach.
The colon is held in its new relation by attaching its omentum to
the gastrohepatic ligament, to the liver surface, or to remnants of
old adhesions in the angle between the pylorus and the liver. The
looser the omentum and the more easily it can be interposed in this
way the better. Andrews’ conclusions are that gall-tract adhesions
are unavoidable, both in disease and after operation, that they are
harmless except in a very few cases, and often beneficial, and that in
the few cases where they do harm this comes from malposition rather
than from adhesions _per se_. He even believes that certain vague
gastric adhesions which might have been benefited by this operation
have been previously treated by gastro-enterostomy.
CHAPTER LIII.
THE OMENTUM, THE MESENTERY, THE SPLEEN, THE PANCREAS.
THE OMENTUM.
The omentum is something more than what it generally appears, _i. e._,
a more or less thick and extensive apron of fat, hanging down in front
of the small intestines, although in this respect alone it serves as
a sort of reservoir or storehouse for fat, which is always drawn upon
as the needs of the system may require. The omentum varies within
wide limits from being the flimsiest veil of peritoneum, whose four
original layers have become so blended as to be lost to recognition,
and which may even be perforated in places with openings through which
strangulation of the bowel is possible, to the thickest and grossest
mass of fat found in the human body, resembling a coarse mat rather
than any finer texture, and having a thickness, in obese individuals,
of two to four inches. Under these circumstances it makes a formidable
obstacle to nearly all abdominal operations. The thickness of the
omentum sustains usually a pretty constant proportion to the amount
of adipose between the skin and the abdominal muscles. In certain
enormously fat individuals one has then to go through from four to
six inches of tissue, mostly adipose, before reaching the rest of the
abdominal contents. This necessitates a longer incision and is always
a disadvantage and impediment. To the operating surgeon, then, the
omentum sometimes appears a nuisance.
It does not deserve, however, to be so regarded, and when properly
viewed the omentum will frequently appear in the role of the surgeon’s
as well as the patient’s best friend. This is due to its power of
shifting itself, and, as it were, enclosing actively dangerous foci
due to any variety of infection, the natural intent being, as it
were, to wrap itself around and thus completely imprison the source
of the trouble, a fact which is often actually accomplished, and by
which life-saving protection is frequently afforded. This is true of
the omentum whether thick or thin. By virtue of the adhesions which
often annoy the surgeon, and which necessitate separation and perhaps
considerable work before the actual trouble is exposed, a protective
barrier is formed and the greater portion of the abdominal cavity shut
off from danger of spreading infection. Moreover, that the omentum has
a really valuable purpose appears from the fact that its removal from
young animals seems to cause retardation of development, and from adult
animals a diminution of resistance to the action of poisons introduced
into the peritoneum. It is the omentum which, to a large extent,
absorbs foreign corpuscles, such as those from extravasated blood.
It helps, moreover, to dissolve blood clots and to facilitate their
disappearance, and after the removal of the spleen it would appear to
vicariously perform at least some of its duties. Thus when the complete
blood supply of the spleen is cut off the organ almost completely
disappears as the result of its absorption by the omentum. (This at
least in experimental animals.)
The omentum serves further useful purpose by plugging various openings
and wounds in the abdominal walls, and thus affording at least a
temporary protection, just as the mucosa sometimes acts in reference to
the stomach. Moreover, it is so vascular, so flexible, and so available
that it may be used for plastic purposes in covering weak spots, lines
of sutures, and the like, in the small intestine or even elsewhere.
These same physical qualities make it extremely prone to escape through
the natural outlets. Hence the frequency of epiplocele or omental
hernia (_q. v._). By a species of such hernial protrusion it has saved
many a life after bursting open or re-opening of recent abdominal
wounds. Sometimes it will escape after removal of a gauze drain which
has not been judiciously placed and protected, this accident then
constituting one variety of postoperative or traumatic hernia.
By virtue of its adhesions, which at first are short and flat, but
which later become stretched into bands, _obstruction of the bowels_
may be produced, or by atrophic or absorptive processes openings
or windows may occur in it with the same result. When participating
in septic processes it becomes infiltrated, is often covered to a
large extent with breaking-down lymph, and may become gangrenous.
All portions thus compromised are best tied off and removed when
exposed during operation. Nevertheless the omentum should be gently
handled, because its venous walls are thin and liable to rupture, and
its bleeding points should be carefully secured, especially after
separation of adhesions.
INJURIES TO THE OMENTUM.
By contusions, lacerations, and punctures various injuries to the
omentum may be inflicted, naturally more commonly when it is the
anterior abdominal wall which has sustained the traumatism. As result
of lacerations, hemorrhages or strangulations may occur. The immediate
danger is, then, from hemorrhage. Indications of such lesions of the
omentum are not specific, but grave symptoms after any abdominal injury
require exploration, and that minute punctures or lacerations should be
repaired, while other injuries should be treated according to obvious
indications.
TORSION OF THE GREAT OMENTUM.
Torsion of the great omentum was first described by Oberst, in 1882,
as a condition found in the sac of a large irreducible hernia. As a
distinct and serious condition it has been reported in about sixty
instances. The condition occurs within the abdomen as simple torsion,
also within hernial sacs, or in both, where the torsion is not limited
to the sac, but extends upward into the abdomen. It is more frequent in
males, and its onset is usually sudden. Of all its symptoms pain is the
most constant and the earliest. This is usually acute and persistent,
and in a large proportion of cases is referred to the right iliac
fossa. Vomiting is not constant; bowel conditions are not significant.
Absolute obstruction is usually rarely noted. In most of the recorded
cases some tumor can be felt on examination, which is hard, tender,
dull to light percussion, and irregular in shape. Meteorism is not
common. Death has occurred in about 15 per cent. of known cases.
Diagnosis previous to exploration can be inferential only, but such
symptoms as above noted should lead to exploratory laparotomy.
TUMORS OF THE OMENTUM.
The most common of the omental tumors are _cysts of inflammatory
origin_, such as may, for instance, be formed by inclusion between
surrounding adhesions or by previous hemorrhage; _lymph cysts_, often
large and multiple, and sometimes of congenital but often of lymphatic
origin, are also occasionally seen. The so-called _omental dermoids_
are usually ovarian products. _Hydatid cysts_ have been found in the
omentum, but only as secondary products. _Omental cysts_ are difficult
or almost impossible of diagnosis previous to operation, which latter
should always be performed, and without previous aspiration, as the
presence alone of any such tumor requires removal. If large they are
most likely to be confused with ovarian cysts. Those which may prove
not to be removable should be drained, after being fastened to the
abdominal wall--that is, marsupialized. _Angioma_ in the omentum is
rare, but has been recorded by Homans and others. _Fatty_ or other
benign tumors are also rare. Primary _sarcoma_ is rarely seen here,
but most of the sarcomas, and all of the carcinomas which never arise
here primarily, but are often seen, are either metastases or direct
extensions. In these forms cancer of the omentum is common.
With extensive involvement of the omentum radical operations in these
cases are seldom advisable. A circumscribed involvement may, however,
be removed, while such operations as anastomoses, enterostomies, and
the like are often necessitated.
Omental tumors are difficult of diagnosis, although they are usually
superficial and overlie the intestines. They are not affected by
respiration. They move laterally and upward, but not downward. If
confined to the omentum proper they cause no functional but only
mechanical disturbances. Obviously in the presence of extensive
adhesions every distinctive feature may be confused.
OMENTOPEXY; OMENTOSPLENOPEXY; TALMA’S OR MORRISON’S OPERATION.
The effect of stasis in the portal circulation is to produce outpour
of varying amounts of serous fluid into the pleural cavity. This
condition, long known as ascites (dropsy), is the most distressing
terminal feature of such diseases as cirrhosis of the liver, cancer,
and the like. The osmotic direction of fluid seems to be reversed, and
transudation tends to go on until intra-abdominal pressure equals that
within the vessels. Absorption is always impeded and finally prevented.
Reflecting on the biophysics of this condition Talma and Morrison,
independently, and at about the same time, suggested an expedient by
which a portion at least of this fluid might be brought back into the
general venous circulation. The plan was to attach the epiploön (the
omentum) to the peritoneum of the anterior abdominal wall in such a way
and over such an area that, by virtue of the adhesions thus produced
and the new vascular anastomosis thus established, a new line of
vascular connections should be formed, so that fluid not returnable to
the vena cava by the usual route should be given a new and artificial
direction. To this fundamental proposition much detail has been added.
Thus Schiassi has shown that, so far as the supply of toxins which
shall pass through the liver is concerned, there are really two portal
veins--the superior mesenteric and the splenic--or he would call what
we usually name the portal system the _splenoportal_. Consequently he
would include the spleen in the above mechanical procedure, especially
in those cases where it participates in the morbid process--_e. g._,
in the hepatosplenic or pre-ascitic form of Banti’s disease, and the
splenomegalic cirrhosis described by Gilbert. In 1904 this problem
was studied from its surgical aspects by Monprofit (French Congress
of Surgeons), who collected 224 operated cases. Of these 84 died, 129
recovered from the operation, and 11 could not be traced. In 25 cases
relapse occurred, in 26 there was improvement, while in 70 there was
claimed complete recovery.[64] In other words about one-third of the
cases thus reported have recovered. He insists, as would every other
surgeon, that with this showing the results would be far better were
cases seen and operated earlier. His statistics are not widely variant
from those of Zesas, who found that out of 254 cases which he collected
67 recovered and 82 died, while 42 were greatly improved.
[64] It is but fair to add that, at the same time, Delagenière
maintained that since, in his opinion, cirrhotic processes in
the liver are due to intestinal infection, the treatment should
consist of combating this and its possible consequences, to which
end he would make a temporary cholecystostomy, having found it of
benefit even in the atrophic, but mostly in the hypertrophic, forms
of disease. Thus in two cases of this procedure, combined with
hepatopexy, the patients survived eight and two years respectively.
Nevertheless he acknowledged that the best results would probably
be secured from combination of cholecystostomy, hepatopexy, and
omentopexy.
In brief, we may hold, with Rolleston and Turner, that it is no longer
advisable to treat ascites by repeated tappings, when the patient is
otherwise in fairly good general condition, for numerous surgeons
have warned against repeated punctures. When liver cirrhosis can be
diagnosticated with fair certainty in the pre-ascitic stage, and when
there is evidence of splenic enlargement or hematemesis, operative
intervention would probably succeed far better than in the later
stages. So far as special indications for operation are concerned they
may perhaps be listed as follows:
1. Thrombosis of the portal vein or its compression by inflammatory
products or by tumor;
2. Cirrhosis of cardiac origin, of the ordinary hypertrophic or even
atrophic types, as well as that due to syphilis or malarial disease;
3. Pseudoliver cirrhosis of pericardial origin;
4. Diabetes of hepatic origin;
5. Splenomegaly combined with hepatic cirrhosis.
_If these indications be met by reasonably early omental fixation
there would seem to be a well-marked place for the procedure_, while
they cannot give rise to any worse results than the repeated puncture
methods of old.
Among contra-indications to such operations may be mentioned the
presence of much biliary pigment in the urine, its absence from the
feces, jaundice, or marked pigmentation of the skin, while distinct
renal insufficiency would also make any surgical procedure hazardous.
The _operation_ itself, done according to the simpler and earlier
recommendations of Morrison and Talma, consists in median abdominal
section, withdrawal of all ascitic fluid, and the deliberate
provocation of adhesions between the diaphragm and the upper surfaces
of the liver and the spleen. This is produced by vigorous swabbing to a
degree sufficient to cause a little oozing from the surfaces attacked.
The margin of the liver may then be fastened to the costal border.
After this the anterior surface of the omentum is also scarified or
swabbed and affixed to the anterior abdominal wall, which has been
similarly treated over as large an area as possible, by means of catgut
sutures placed to the best possible advantage for the purpose. Some
operators have preferred to close the abdomen without drainage, some to
insert a tube in the lower margin of the wound for a day or two, and
others to drain the lower abdominal cavity through a small, distinct
opening above the pubes. Theoretically much advantage attaches to
permitting no immediate re-accumulation of fluid. Practically, however,
danger also attaches to it, _i. e._, from the difficulty of so managing
the dressings as to avoid infection.
Schiassi has modified the above procedure and has made an
_omentosplenopexy_ of it as follows: He makes a right-angled incision
across the median line and then another several inches downward along
the left semilunar. The tissues down to the peritoneum are reflected
toward the umbilicus, and a transverse deep opening is made just
below the horizontal skin incision. Through this the omentum is drawn
upward and spread over the right portion of the exposed peritoneum,
where it is sutured in place. Through another vertical opening in
the peritoneum, near the vertical skin incision, the spleen is then
exposed, a piece of gauze is placed under each pole of that organ, and,
while thus lifted, by means of a long curved needle three to six catgut
sutures are passed through it, including also the peritoneum and all
the superficial structures except the skin, this being closed later and
separately.
Finally, whatever operative method be selected it is important that it
be done _early rather than late_, bearing in mind that “the resources
of surgery are rarely successful when practised on the dying.”
THE MESENTERY.
No one has done more to forcibly place before the surgical profession
those anatomical features of the mesentery which most concern them
than Monks, who, for instance, has demonstrated the fact that the
mesentery is practically an enormous fan, composed of two layers of
peritoneum, between which are spread out the vascular structures and
more or less fat, and whose border contains the intestinal tube. This
fan at its base is but a few (six) inches in length, while along its
outer border, when completely unfolded, one may measure a distance of
twenty-one to twenty-three feet. Not one of the structures contained
between its layers can be regarded as a negligible quantity. The
arterial distribution in the mesentery is _terminal_ in the same sense
that it is in the brain. Consequently dependence can be placed only
on a sufficient blood supply for any given portion of the intestinal
tube when its mesentery is intact. If necessary to sacrifice a portion
of the mesentery it is requisite to resect that portion of the bowel
which is dependent upon it for blood. This will explain the reason why
thrombosis or embolism of the mesenteric vessels so quickly determines
the death of that portion of bowel supplied by the occluded branches,
this being equally true of the tiny fragment known as the appendix or
of the entire bowel.
The root of the mesentery is placed obliquely across the spinal
column, arising from the left side above and crossing obliquely to the
right side below. Monks has shown how easily we may make practical
application of this fact in determining approximately to what part of
the bowel tube a given loop may belong, since it is necessary only to
follow it down to the mesenteric insertion, and from this estimate what
proportion of the entire distance is represented.
INJURIES OF THE MESENTERY.
Obviously the mesentery may be injured in the same way as any other of
the abdominal viscera, either by contusions, lacerations, punctures, or
otherwise. Here the immediate danger is from hemorrhage, while a more
remote but quite possible danger is that of _thrombosis_ of some of the
vessels and its consequences in the direction of _necrosis_.
Erdmann has recently reported two cases of complete detachment, for
several inches, of the mesentery at the intestinal border, as well as
a case of multiple lacerations in the peritoneal coat of the mesentery
with hematoma. While the latter might not be so serious, the former
will almost invariably determine gangrene of bowel from lack of blood
supply; all of which shows the difficulty of diagnosis, and furnishes a
further argument for intervention when, after an abdominal contusion,
the patient has abdominal rigidity or pain, with or without evidences
of hemorrhage, either from the stomach, rectum, or bladder. These
features are sufficient without the addition of those by which a more
certain or minute diagnosis can be made.
THROMBOSIS AND EMBOLISM IN THE MESENTERIC VESSELS.
Mesenteric occlusion was first described by Virchow in 1859. Whether it
involves first the arterial or the venous circulation seems to matter
but little. Of course in one case it is to be regarded as embolic, in
the other as thrombotic. In this location either condition is harder
to explain than in many other places. The mesenteric veins have no
valves and collateral circulation is poor. Mitral stenosis and arterial
sclerosis will often account for the former. For thrombosis search
has to be made for some local infectious process, either in the veins
of the pelvis, the kidney, or the intestines. It seems to occur least
often when it might be most expected, _i. e._, after typhoid.
The blood supply may be simply shut off from portions supplied by one
of the mesenteric vascular branches, or, should the main branches be
involved, from the entire intestinal tract. I have myself reported two
cases of practically complete rapid gangrene of the entire alimentary
canal, due to lesion of this kind, explanation being forthcoming in
neither case.
=Symptoms and Signs.=--The more complete the occlusion and the more
extensive the area deprived of blood the more sudden and overwhelming
will be the onset. This is always sudden and characterized by intense
and often paroxysmal pain, so agonizing, in fact, as scarcely to be
quieted even by morphine. While this is common, instances have been
known in which the disease has run an almost painless course. Diarrhea
is frequently an early symptom, evacuations being profuse and bloody.
Symptoms of obstruction are not uncommon, perhaps followed later by
loose stools. Vomiting occurs usually early and becomes fatal in
a few hours. The general physical signs are intensely acute, with
rapid pulse, subnormal temperature, and meteorism, beginning early
and becoming more pronounced. Abdominal rigidity also constitutes
a distressing feature, which, while indicating the gravity of the
condition, masks its diagnostic features. If the patient live long
enough fluid will accumulate in the peritoneal cavity. The cases
terminate with complete collapse and delirium. When the inferior
mesenteric vessels are involved tenesmus is a more prominent
characteristic than when the lesion is confined to the upper, as the
colon and rectum are supplied from the former.
The surgeon may have to distinguish between the condition just
described and the following: Perforating ulcer of the stomach or
duodenum (which will have a previous history), possibly so-called
phlegmonous gastritis; acute obstruction of the bowel (whose onset is
rarely so acute); pancreatitis, which would, at least at first, produce
almost identical symptoms; acute splenic infarct (when the early
symptoms would probably be referred to the region of the spleen); acute
appendicitis; acute cholecystitis, and that acute peritonitis to which
either of these might lead; a ruptured ectopic pregnancy; and possibly
certain intrathoracic lesions, especially pneumonia in the lower lobes.
Mesenteric occlusion is essentially a fatal condition, at least when
extensive. There have been known cases where so limited an extent of
the bowel and mesentery were involved that an exsection, made early,
has proved successful, but when anything like the entire alimentary
canal or its major portion becomes necrotic there is no hope for the
patient.[65]
[65] Annals of Surgery, April, 1904.
ABSCESS OF THE MESENTERY.
Abscess formation may take place within the mesenteric structures,
as an expression of acute septic infection or of a mixed infection
of old tuberculous foci in the nodes. A careful case history or some
peculiarity of local conditions may occasionally furnish a clue to
the conditions, otherwise it will not be distinctly revealed until
such operation as may be necessitated by unmistakable indications of
the presence of pus or by autopsy. Inasmuch as operation can scarcely
exaggerate the danger of the condition it would be best attempted when
such abscess is suspected. When the meso-appendix is involved, as is
often the case, the trouble may be so walled off that it is almost a
purely local affair.
TUBERCULOSIS OF THE MESENTERY.
Aside from the common miliary expressions of acute tuberculosis
which are seen so frequently dotted all over the bowel surfaces
and the expanse of the mesenteric folds, there is a peculiar form
of involvement of the mesenteric nodes, _i. e._, those which are
especially clustered along its root. These are always involved in
general tuberculous peritonitis, though but slowly in the absence of
such generalized features. To the slow forms of this condition the
early writers gave the name _tabes mesenterica_. The more limited
the involvement the greater interest the lesion has for the surgeon,
since it may be so limited to the nodes of a single coil as to justify
extirpation. In fact, if such a focus could be easily and thoroughly
removed without too much disturbance of circulation, tabes might be
remedied by surgery. Not very frequently, however, do the location
or the arrangement of a collection of tabetic nodes permit of their
enucleation. They are usually too numerous, too large, too degenerated,
too adherent, or the patient otherwise too extensively infected.
The acuter expressions of mesenteric tuberculosis may be considered
as already sufficiently discussed under the caption of Tuberculous
Peritonitis.
Occasionally a localized, slightly mobile tumor, especially in
the ileocecal region, may cause suspicion, or may be correctly
diagnosticated, by taking note of other symptoms, along with a good
case history. Especially is this the case in patients known to be
tuberculous. This is particularly true of the appendix and its
mesentery, where a tuberculous gumma may attain considerable size
before there is any active breakdown. The relation between this
condition and tuberculous ulceration within the bowel will also be
obvious. Moreover, it is of interest to recall that calcification of
mesenteric nodes is not impossible, and that occasionally chalky tumors
in this location may be thus explained.
There is also a possibility of involvement of the mesenteric nodes in
_constitutional syphilis_ and in _actinomycosis_.
The _treatment of mesenteric tuberculosis_ should consist of
exploration and orientation, followed by whatever procedure the
condition thus revealed may require--_e. g._, abdominal irrigation,
with or without antiseptics, extirpation, drainage, or even resection
of a portion of the bowel (appendix, cecum, etc.).
CANCER OF THE MESENTERY.
The other condition in which the mesenteric nodes are especially
involved is the cancerous. In this location, as in the omentum, sarcoma
may be primary and endothelioma may occur, but carcinoma is never
primary, although it invariably occurs as an extension from epithelioma
or adenocarcinoma of the bowel. Otherwise cancer will appear here as
an expression of metastasis. In all primary cancers of the intestine
early involvement of the mesenteric nodes may be looked for, while
involvement of everything in the vicinity, even the aorta or spine,
will occur in due time, often with more or less breaking down. There
would be little justification for attacking any cancerous portion of
the mesentery or any cancerous nodes unless the primary lesion could be
radically removed. Generally speaking, in bowel cancer invasion of the
deep-seated nodes imparts to the case such an unfavorable aspect as to
justify only palliative (anastomotic) rather than radical measures.
CYSTS OF THE MESENTERY.
Cysts of the mesentery are, in the main, similar to those met with
in the omentum (Fig. 631). A peculiar form of mesenteric cyst is
produced by obstruction and consequent dilatation of one or more of
the lacteals, and is known as _chyle cyst_. It may attain considerable
size and occur in multiple form. The contained fluid is naturally milky
and corresponds to that seen in chylous ascites and hydrocele. These
lesions are only recognized after exploration. When found they are to
be extirpated, on general principles, usually by enucleation, with
ligature of the connecting lacteals and avoidance of all unnecessary
disturbance of blood supply.
[Illustration: FIG. 631

constriction passes through the layers of the mesentery. (From a case
occurring in Richardson’s practice.)]
THE SPLEEN.
The spleen is often an object of surgical interest, not alone because
of the frequency with which it is enlarged in the course of the acute
surgical infections, but because it is something more than a reservoir
for blood. Thus it seems to enlarge to accommodate blood forced in from
the exterior under conditions of extreme exercise, etc., and in the
higher vertebrates it seems to be a place where blood corpuscles are
destroyed, especially those which are already disintegrating, rather
than one in which they are manufactured. It is claimed by Ehrlich that
the splenic enlargement of the infectious diseases is produced mainly
by the products of disintegrating leukocytes which are allowed to
accumulate.
ANOMALIES OF THE SPLEEN.
Of the _congenital anomalies_ or defects the surgeon is mainly
interested in the fact that _supernumerary spleens_ are common, being
found perhaps in one out of four bodies varying in number up to
thirty or forty, located near the hilus in the gastrosplenic omentum,
in the great omentum, or even in the pancreas. Doubtless after some
splenectomies no peculiar symptoms are produced, which is due to the
fact that some of the supernumerary organs have taken up the splenic
function. The spleen varies in shape to such an extent that the notch
upon which so much stress is often laid in diagnosis will not always
be found along the anterior border. In cases of transposition of the
viscera the spleen may be found on the right side. It has been found
in the sacs of large umbilical hernias and in the left thorax after
defects of the diaphragm.
INJURIES TO THE SPLEEN.
The spleen may be injured by itself or along with other viscera. The
most common injury is from contusion, which produces more or less
disintegration or rupture and hemorrhage. The organ is so friable
that it may literally burst under a comparatively slight force, other
conditions being favorable. Doubtless minor degrees of these injuries
pass unnoticed or are followed by some local peritonitis and adhesions.
On the other hand the spleen may be actually fragmented, with
necessarily fatal consequences unless promptly operated. _Rupture_ is
especially likely to occur after those infectious diseases which cause
its enlargement--_e. g._, typhoid.
In case of injury there is, in addition to the history, a prompt
location of pain in the region of the spleen, with signs of
intra-abdominal hemorrhage, but without blood in the urine; perhaps
with tumor or dulness on percussion, and always with abdominal
rigidity, all of which point to the serious nature of the injury and
_demand exploratory section_. Should this reveal a slight injury it
may be repaired with ligatures or sutures. More serious tears or
perforations are treated by gauze packing through a sufficiently open
wound, while the most serious cases of pulpifaction call for complete
_extirpation_. When the blood supply of the spleen is left in doubt its
total removal will be far the safer course to adopt. Obviously such an
operation should include examination of all the viscera and a careful
toilet of the peritoneum.
ABSCESS OF THE SPLEEN; SUPPURATIVE SPLENITIS.
Pus may form within the spleen in consequence of septic infarcts
or thrombosis, or it may be due to the extension of trouble from
adjoining foci, or to pyemic metastasis. Splenic abscesses are usually
localized, but the pyemic forms are always multiple, miliary at first,
but coalescing into larger collections, and practically destroying the
organ if the patient live long enough. The infectious fevers may be
followed by suppuration of the spleen, which is also known to occur
rarely in malaria.
=Symptoms.=--The symptoms of splenic abscess are indeterminate
until the capsule is involved and a perisplenitis--_i. e._, a
local peritonitis--results, after which pain becomes severe. These
collections occasionally discharge spontaneously into the colon or even
into the stomach.
On general principles any abscess which can be located, even somewhat
vaguely, should be attacked. After the abdomen is opened, preferably
through the left semilunar line, the exploring needle may be used,
especially if adhesions be present.
GANGRENE OF THE SPLEEN.
Gangrene of the spleen is the result of a still more rapid, otherwise
similarly septic or thrombotic process, or of severe injury, by which
circulation is practically cut off. It is a condition which rarely
permits of any surgical help, though if it could be foreseen it might
be prevented by an early splenectomy.
HYPERTROPHIES OF THE SPLEEN.
Enlargement of the spleen occurs during numerous acute and chronic
_infections_--_e. g._, typhoid, malaria--in connection with certain
affections of the _liver_; in consequence of interstitial or gummatous
forms of _syphilis_, with or without similar lesions in the liver;
in acute _peritoneal infections_; in general _septic_ and _pyemic_
disturbances; in _rickets_ and the _status lymphaticus_; in the various
forms of _leukemia_, _Hodgkin’s disease_, and _pseudoleukemia_,
and in that somewhat peculiar type known as Banti’s disease, or
_splenomegaly_. In fact the spleen enlarges under so many conditions
that its hypertrophy is an expression of a general infection rather
than of any pronounced or particular type of the same. Minor degrees of
enlargement have often passed unnoticed or given little or no trouble.
When seriously overgrown its principal features are its inconvenience,
weight, and size. The condition is recognized by its characteristic
shape and notch (See above.) By its extension upward it can be usually
distinguished from a tumor, of the kidney.
Every splenic enlargement, especially chronic, should lead to a
careful blood examination, by which, among other things, malaria may
be recognized or excluded, while the degree and form of leukemia, if
present, may be estimated. The lymph nodes throughout the body should
also be carefully examined. Splenomyelogenous leukemia, for example,
is progressive, severe, and marked by cachexia and anemia of peculiar
type. In many of these cases there is a tendency to hemorrhage, both
from surfaces and into the tissues. The hemoglobin is much reduced and
prognosis after any operation is unfavorable. (See chapters on the
Blood and the Lymphatic System.)
_Banti’s disease_, or _splenomegaly_, seems also a somewhat peculiar
type of lesion which is probably due to an infection proceeding from
the intestinal canal, and involving the liver in its later course. In
its last stage there is a tendency to hepatic cirrhosis, with ascites,
and hemorrhages in any part of the body are frequent.
_Removal of the spleen_ for any of these conditions is usually a
precarious procedure. It has been more successful when performed for
malarial hypertrophy than for other conditions, the patient’s chances
being then about three out of four; but here, too, the lesion is
usually amenable to other treatment. If done in the early stages of
Banti’s disease it would seem to be strongly indicated, but not in the
later stages, when the liver is involved and the abdomen full of fluid.
In the leukemias it has succeeded in a few instances. It is mostly
indicated in those cases where hemorrhages occur early.
The Röntgen rays have recently been shown to have an excellent effect
in many of these cases and are worthy of trial. Especially in the
leukemic forms, in connection with arsenic internally, they offer
probably the best prospects.
SPLENIC DISPLACEMENTS.
While, under ordinary circumstances, the supports of the spleen may
seem equal to ordinary needs they prove insufficient in many cases of
marked enlargement. Hence results _displacement_, or the so-called
“wandering spleen,” which may be due to the results of injury, to tight
lacing, possibly to congenital relaxation of ligaments, but mainly
to hypertrophy, with increase in size and weight. When the spleen
enlarges it descends toward the umbilicus, but it has even been found
in the pelvis. As it prolapses it brings down with it the stomach
and the pancreas, thus interfering with the circulation of all three
organs and producing a train of distressing secondary consequences.
A long-drawn-out splenic ligament may be much stretched and may even
become finally _twisted_, thus causing gangrene of the spleen from
torsion of its support. Moderate displacement and stretching produce
discomfort, pain, and disturbance of function. Such a displaced spleen
is to be recognized by its shape, size, and notch, and is occasionally
to be distinguished from a wandering kidney. When displaced its normal
location will not be dull upon percussion.
=Treatment.=--Palliative treatment, which may be tried first, calls for
whatever drugs may be needed to unload the bowels, but especially for
rest in bed and support by suitable abdominal binder, with or without
a pad. If the spleen itself be much enlarged it may also be subjected
with a judicious frequency to the _x_-rays.
_Operative help_, which is the only measure when other treatment fails,
should come either through a _splenopexy_ or _splenectomy_, preferably
the former, save in the presence of serious disease which may call for
its extirpation. Nevertheless splenopexy, which seems so simple and so
promising, is often unsatisfactory because of the friability of the
spleen itself and the weakness of its capsule. Here, as in hepatopexy,
the intent is to produce adhesions, by scarification of the external
peritoneal surroundings, which is made through a suitable incision,
directed usually along the left costal border; after thus intentionally
provoking adhesions, sutures may be used if there be any prospect of
their being serviceable.
[Illustration: PLATE LVI
Upper Abdominal Viscera, showing their Normal Relations. (Sobotta.)]
NEOPLASMS OF THE SPLEEN.
Splenic _cysts_ of the _serous_ or _blood type_ are seldom seen. Even
_hydatids_ here are uncommon. _Sarcoma_ of the spleen may be primary;
_carcinoma_ is due to extension or metastasis. In proportion as splenic
tumors develop they may be recognized as involving this particular
organ. While a careful blood examination may permit the exclusion of
certain conditions, exact early diagnosis will scarcely be made without
exploration, which is justifiable whenever the blood count would
indicate it. After exposing the lesion the surgeon is for the first
time in a position to judge whether to drain or extirpate a cyst, or
remove part or the whole of the spleen itself.
OPERATIONS UPON THE SPLEEN.
Besides those operations addressed toward fixation of a more or less
enlarged or wandering spleen a _splenotomy_ can be made--_i. e._,
incision and drainage at any suitable point, anterior or posterior,
which can be satisfactorily exposed; and evacuation of fluid may be
followed, with or without suture of the deep to the external wound, by
gauze packing or tubage, combined, if necessary, with counteropening or
posterior drainage.
=Splenectomy.=--Total removal of the spleen is performed through an
incision which should be made ample for the purpose, either along the
costal border or the left semilunar line or by combination of both. A
median incision may be also utilized if it will permit better access.
Splenectomy, under ordinary circumstances, would not be a difficult
operation, but with the organ enormously enlarged and the vessels
dilated, as they may be, it becomes usually a formidable procedure. The
most serious difficulty and danger arise from the numerous adventitious
vessels which may connect the spleen with the diaphragm or with some
of its other surroundings, and whose location is to be made out before
an attempt is made to remove it. Thus, in one instance, I have seen
an adventitious vein, the size of the little finger, between the
upper splenic surface and the diaphragm. Through such large vessels
torrents of blood will pour unless they be first secured. All such
connections then with the stomach and the diaphragm have to be ligated
and separated with great care, while gentleness of manipulation is
requisite throughout the operation. The spleen may be reached and
adhesions be located with great speed of manipulation, but in the
depths of such a wound valuable time may be consumed and much blood
lost, all at a time when the patient can least tolerate them. Oozing
from vessels which cannot be secured should be checked by gauze packing.
THE PANCREAS.
The anatomical features of the pancreas which have most interest
for the surgeon are the facts that its head is in contact with the
duodenum, and lies usually so closely against the second portion of
the former as to surround from one-fourth to one-third of its lumen.
Becoming adherent at this point it may then produce obstruction high
up in the intestine. In rare instances it may even completely surround
the duodenum, and thus may, when swollen, cause tight constriction of
the latter. Should this condition be met with a gastro-enterostomy
would be the proper measure for relief. These intimate relationships
account for the spread of disease from the pancreas to the intestine,
rarely in the reverse direction. The pancreas lies also in contact
with the stomach along its anterior peritoneum-covered surface, and
malignant disease travels easily from one to the other. Ulcers of the
stomach, favorably situated, may also be followed by adhesion and
inflammatory infiltration of the pancreas, by which the viscera are
cemented together, the same result following duodenal ulcer, as well
as serious disease about the biliary passages. Thus under a variety of
circumstances the operator may find these parts so cemented as to be
separated only with the greatest difficulty, or perhaps not at all,
without causing laceration or rupture of one or more of them, with
escape of contents which are often septic. Therefore when there is
reason to fear this accident it will usually be safer to simply make a
gastro-enterostomy. (See Plate LVI.)
The relations of the biliary ducts to the pancreas are most important,
the association of the common duct with that of Wirsung having the
greatest bearing upon a variety of conditions, which are nearly all
essentially surgical. The former, descending along the head of the
pancreas, comes in contact with the duct of the latter, and passes
alongside of it for a short distance before entering the intestinal
wall. In about two-thirds of individuals it is completely enclosed
by the pancreas. In the other third it lies in a deep groove upon
it. Resting here, as it were like Siamese twins, it will be easily
seen how disturbance in one duct or its source may be reflected to
the other. When the common duct lies in a groove it is less likely to
be seriously compressed by pancreatic engorgement than when actually
embedded in pancreatic tissue. The degree of resulting jaundice may
thus be dependent upon anatomical conditions not determinable before
exploration. Such pressure doubtless accounts for many cases of
so-called catarrhal jaundice. When the condition becomes constant, or
nearly so, a chronic interstitial pancreatitis may be assumed, which
really warrants an operation--_i. e._, cholecystostomy with drainage.
When a gallstone is passing through the common duct, especially when
lingering or impacted, it may have in turn reversed this condition,
and, by obstructing the pancreatic duct, set up as a consequence
pancreatic stagnation and consequent digestive disturbance, and such
other internal conditions as invite infection from the duodenal cavity,
with a more or less lively pancreatitis, perhaps even of fulminating
type, by which life may be jeopardized.
The pancreas, however, being usually provided with two ducts, the
second (that of Santorini) is often represented as an additional
safeguard, since it usually has a separate opening into the duodenum
below the ampulla. Opie carefully studied 100 cadavers and found that
in more than 50 of them the accessory duct could be of no use or
relief, and that in only 10 instances did two independent ducts enter
the intestine, while in the other 90 they were united, and in 21 of the
latter the accessory duct had become obliterated. Moreover, in only
6 of the 100 instances was it larger than the duct of Wirsung. This
will show, then, how little reliance may be placed upon the duct of
Santorini. Moreover, no matter which duct is opened, or whether both
are, so long as pancreatic fluid can escape there is an open channel
for infection, and when it cannot escape it may be seen that infection
has already occurred and is manifesting its pressure consequences.
Chemosis of mucous membrane may be the first mechanical result of such
infection, but this is sure to be followed by interstitial sclerosing
and compressing effects.
The normal duct opening in the duodenum is also a matter of surgical
interest. The ampulla of Vater, within the second portion of the
duodenum, is usually described as a conical protrusion or papilla,
having an average length of 4 Mm., with an opening 2.5 Mm. in diameter,
this being the narrowest portion of the common duct, but from this
arrangement there are many variations. The ducts may join at some
distance from the intestine, or they may open independently into a
depression or into a protrusion, and the ampulla be thus totally
wanting, all of which has the greatest possible bearing upon what may
happen during the passage of gallstones, for instance, or by infection
and according to its direction; and may account for the difficulty met
in certain cases, as when, for example, it becomes necessary to incise
the duodenum and open the ampulla for the removal of a pancreatic or
biliary calculus. It will emphasize, too, the necessity for always
exploring the common duct by opening the biliary passage and thus
making sure of its patency.
ANOMALIES OF THE PANCREAS.
Congenital anomalies include not only those of the ducts above
mentioned, but the presence of _accessory masses_, like the accessory
thyroids, which may occasionally lead to confusion and perplexity.
Furthermore, accessory nodules of pancreatic tissue may be found
alongside the ducts, or even in the walls of the stomach and intestine,
where they are probably present more often than is generally
appreciated, and are to be explained by the embryology of the parts,
since the pancreas is known to take origin from a cluster of cells in
the wall of the upper end of the developing intestinal canal. They have
been seen also along the line of a persistent vitelline duct. Such
small accessories, when present, usually empty by minute independent
ducts into the intestine. On the same embryonal grounds are to be
explained other anomalies occasionally met, such as separation into
detached portions. The existence of accessory pancreatic glands is also
held to account for the absence of glycosuria in certain cases where
the principal portion of the pancreas is itself extensively diseased.
GLYCOSURIA.
Glycosuria is so associated with the popular conception of pancreatic
disease that it seems imperative to state what importance should be
attached to it. It is now clearly established that the so-called
“islands of Langerhans” have to do with the elaboration of a certain
glycolytic ferment, and that the failure in its supply to the blood (it
being regarded as an internal secretion) is followed by the appearance
of sugar in the urine. These islands are not connected with the ducts,
at least not in the vertebrates, and usually escape pressure effects
in chronic interstitial pancreatitis of the interacinous as well as of
the interlobular form. This explains the accompaniment of diabetes in
some instances of pancreatic disease and its absence in others. Again,
if only part of the pancreas be affected, as in cancer, the remaining
healthy portion may still afford a sufficient amount of this ferment to
supply the body needs.
The uncertain symptomatology of the slower forms of pancreatic disease
is to be accounted for by the fact that, with the exception of its
glycogenic function just mentioned, all its other functions may be
vicariously assumed by other organs of the body. Thus as a compound
racemose gland it furnishes--
1. Trypsin, a proteolytic ferment;
2. Amylopsin, a starch-splitting ferment;
3. Steapsin, a fat-digesting ferment; and
4. A milk-curdling ferment.
The first of these functions may to some extent at least be assumed by
the stomach and the others by the bile and intestinal juices. (Mayo
Robson.)
INJURIES TO THE PANCREAS.
Injuries to the pancreas may occur with or without external
traumatisms. By any kind of injury which affects the gland it is
probable that its glandular structure may be so disrupted as to set
free an autodestructive secretion, which, by softening and weakening
vascular walls, may lead to hemorrhage and to the accumulation of a
collection of inflammable material, which is a good culture medium,
and which needs only the spark of infection to be easily aroused
into a conflagration. That possibility of infection is imminent is
apparent from the relations of the adjoining viscera and their ducts,
as already outlined. However, the same is true of even a first and
spontaneous hemorrhage, as of the clot, however produced. It has been
held that the manipulations to which the pancreas has been unavoidably
submitted during many operations may lead to its acute inflammation or
destruction. On the other hand, there seems no doubt but that it is
sometimes much relieved or benefited by a mild massage as a part of
the operative procedure. Mayo Robson has suggested that concretions
may thus be pushed along or adhesions removed, or, as it seems to me,
circulatory equilibrium restored and autonutrition improved.
Aside from the injuries which the pancreas may receive during
operations it is unquestionably the site of hemorrhages produced by
_contusions_ of the abdomen, although these are rare, and of injuries
produced by deeply penetrating _wounds_, especially those caused by
a stab or gunshot. The immediate result of a serious wound might be
hemorrhage, perhaps even a large escape of blood filling the lesser
cavity of the peritoneum. Such injuries are always to be treated
surgically, _as any external contusion followed by serious collapse and
evidences of internal hemorrhage should be promptly explored_, and,
even more so, _every case of penetrating wound_. Should blood be found
to be escaping from the pancreas the bleeding vessel may be sought and
secured, or, if necessary, a portion of the organ extirpated, since
no danger can be greater than that of uncontrolled bleeding. It is on
record that through an extensive gash in the abdomen the pancreas has
not only been exposed, but has partially escaped, and one case report,
apparently authentic, details its subsequent sloughing and spontaneous
separation.
Any wound of the pancreas which needs no further attention may at least
be sutured if it can be exposed. Nearly all surgical attacks upon this
viscus will require extensive incision and more or less emptying of
the upper abdominal cavity. It may now be of great assistance to place
the patient in the semi-upright position in order that the viscera may
gravitate toward the lower part of the abdomen--_i. e._, to reverse the
ordinary Trendelenburg position.
NON-TRAUMATIC SURGICAL DISEASES OF THE PANCREAS.
These diseases include especially the acute infections, the chronic
lesions, and the occurrence of neoplasms or calculi.
Certain local and general conditions predispose to pancreatic disease
of any type. Among them are to be reckoned--
1. _Injury_, either by accident in the ordinary course of events,
as by contusions or penetrating wounds, or bruising during the
manipulations of operation;
2. _Anatomical anomalies_;
3. _Hemorrhages_ into the substance of the gland, whether from
vascular changes or other causes;
4. _Obstruction along either the biliary or pancreatic ducts_,
whether due to catarrh, calculi, adhesions or stricture, parasites
(worms) or cancer;
5. General _toxemias_: typhoid syphilis, influenza, mumps, and the
like.
The principal exciting causes are the various infections which
may proceed from the blood, as in pyemia or syphilis, or from the
alimentary canal, which is never free from bacteria, either by
adhesions and continuity, as from gastric ulcer and cancer, or by those
natural passage-ways, the ducts.
When summed up the most common of all the causes of pancreatic disease,
acute or chronic, will be found to be _cholelithiasis_, with some of
its variant consequences or complications. This will help to make clear
the reason for operating on the biliary passages in most cases of
pancreatic disease, especially the more chronic forms. A stone impacted
in any portion of the common duct, especially in its terminal portion,
after it has come into relation with the duct of Wirsung, may cause
an amount of disturbance disproportionate to its size. Moreover, a
stone impacted at the orifice of the duct will permit the entrance of
bile into the pancreatic canal, where it does not belong, and where of
itself it may cause trouble.
ACUTE AFFECTIONS OF THE PANCREAS.
These include--
1. _Hemorrhagic pancreatitis._
(_a_) Ultra-acute, where hemorrhage precedes infection, and bleeding
occurs outside as well as inside the gland.
(_b_) Acute, where inflammation precedes hemorrhage, the latter being
less profuse and occurring in patches.
2. _Gangrenous pancreatitis._
3. _Suppurative pancreatitis._
(_a_) Diffuse, destructive.
(_b_) Subacute, localized, with abscess formation.
=Acute Pancreatitis.=--Acute pancreatitis is a distinct form of
disease, like appendicitis, with an etiology and symptomatology of its
own, which has been recognized only within the past twenty-five years.
This statement will account for the fact that so little reference to
it is made in any but the recent text-books. In fact it is to the
writings of Fitz, of some fifteen years ago, that the world owes its
first keen interest in the subject. By no means a frequent disease, it
nevertheless occurs with frequency sufficient to make it inexcusable
for the practitioner to fail to take it into consideration, although he
may waver in diagnosis.
The predisposition to infection which previous injuries, especially
minute hemorrhages or previous pathological conditions, seem to afford
has been already mentioned, and a history of previous injury or
digestive disturbances will aid in diagnosis. The exciting cause is,
however, in nearly every case when not distinctly traumatic, connected
with previous disease in the biliary tract, either cholelithiasis or
cholangitis. Reference to what has been said above, and a consideration
of the anatomical relations, will show how readily an infectious
process can travel upward from the duodenum into the pancreatic duct,
as well as into the common duct; or how, passing down the latter, it
may speedily find its way up the former. The previous condition of the
tissues, and the activity or virulence of the infective organisms, have
to do with the degree of acuteness of the resulting pancreatitis. This
is sometimes of such overwhelming toxicity that the entire gland dies
almost as does the appendix, within a few hours, the result being an
acute necrotic condition that of itself is necessarily fatal.
=Symptoms.=--Acute pancreatitis gives rise to symptoms which, in
general, assume the clinical form of an _acute peritonitis of the upper
abdomen_. It commences with sharp pain in the epigastrium, accompanied
by faintness, nausea, vomiting, and collapse, while tenderness over the
pancreas is an early symptom, and swelling or enlargement can sometimes
be detected. Constipation is so frequently a feature that the diagnosis
of acute bowel obstruction is sometimes made, but it will be found that
obstruction is not complete, for flatus may pass and enemas may be
successful. The pain becomes paroxysmal, is increased by movement and
pressure, while the tenderness becomes more localized. Meteorism may so
quickly succeed the other symptoms as to make physical signs uncertain,
while rigidity of the abdominal muscles makes them still more vague,
yet affording in itself a sign of value. Vomiting intensifies the
pain and the vomitus changes from food to bile, and then to blood,
which is dark and altered. Hence jaundice may be an early feature,
in which case it becomes more marked as the disease progresses, and
may become intense. This is likely to be the case if the exciting
cause prove to be a stone impacted at the ampulla. The face indicates
profound distress and disturbance. The temperature affords no certain
indication, save that in the most serious cases it may be subnormal.
On the other hand, as the case progresses, the pulse becomes small and
rapid. Every expression of overwhelming toxemia is added, and delirium
usually precedes death. In fact death may follow the first expression
of pain, in unrelieved cases, in from two to three days. Other less
acute expressions of the same general character are met with in the
so-called subacute forms of pancreatitis.
While the postmortem findings differ in various instances the symptoms
above noted do not vary conspicuously. They differ rather in intensity
only, in accordance with the gravity of the case.
The pathologists have described various forms of pancreatitis as
the _hemorrhagic_, the _gangrenous_, the _suppurative_, and those
distinguished by _fat necrosis_, as well of the omentum as of the
pancreas itself. These distinctions have the greatest interest for
those engaged in minute research and are not to be regarded lightly.
They have no small interest for the clinician, since prognosis is in
some measure dependent upon them. Nevertheless the symptoms of the
condition are but slightly modified, whether the destructive process
assume one or the other of these types, and the therapeutic indication
is the same for all--namely, the _earliest possible operation_.
If pathologists were better agreed on their pathology it might be
worth while to give more space here to this aspect of the subject. It
is, however, not yet certain, for instance, whether in a given case
inflammation precedes hemorrhage, or whether hemorrhage occurs first
and the outpour of blood is suddenly invaded by bacteria. In fact it
is probable that sometimes one thing occurs and sometimes the other.
Certain it is that the pancreas is not only loosely held together, and
consequently disrupts easily, but that it quickly succumbs both to its
own digestive juices and the disintegrating effect of bacteria, so that
putrefaction quickly occurs hours before life is extinct. The morbid
excitement quickly spreads to the adjoining peritoneum, and along it,
so that a more or less generalized peritonitis soon complicates the
case. Mayo Robson inclines to the view that in the most fulminating
cases the hemorrhage is the prior lesion.
=Diagnosis.=--The diagnosis should be made mainly from perforating
gastric or duodenal _ulcer_; phlegmonous or gangrenous _cholecystitis_
or _cholangitis_; rupture of the biliary tract, with escape of
contents; fulminating _appendicitis_; acute intestinal _obstruction_,
including internal hernias, and acute _mesenteric thrombosis_ or
_embolism_. Fortunately in every one of these conditions prompt
operative intervention is alike demanded, save possibly in the last
named; while even in the latter diagnosis cannot be made without
it, and it may still be possible to accomplish something if the
occlusion be not too widespread. A history of previous “dyspepsia”
or “indigestion” may point to the stomach or the biliary channels;
repeated hemorrhages to gastric ulcer, and repeated attacks of pain
to gallstone trouble. General tympanitis would indicate intestinal
obstruction, especially if no flatus were passed, while when limited to
the upper abdomen it would be more suggestive of pancreatic disease.
This would be corroborated by vomiting of blood, while fecal vomiting
would indicate obstruction. Tenderness and tumor located in the region
of the gall-bladder would point rather to it as the source of trouble,
while in pancreatitis something distinctive may be perhaps made out
by palpation and percussion, and the tenderness will be complained
of alike on each side of the middle line. Abdominal rigidity, while
general, is usually most pronounced near the site of the most important
lesion. Much importance is attached by Halsted to excessive pain, and
to cyanosis of both the face and the abdomen. The latter may be helpful
as a corroborative indication, but is certainly not always present,
and, on the other hand, is seen in many cases of general peritonitis.
Glycosuria is rarely a feature of the acute cases.
=Treatment.=--This is of necessity not only _surgical_, but, to be
effective, should be _prompt_, every added hour of delay causing
increased danger. While arranging for this it is possibly justifiable
to allay pain by giving morphine hypodermically. The colon should be
emptied by a copious enema. Collapse is to be combated by the usual
means, including hypodermoclysis or infusion, perhaps with the addition
of a little adrenalin to the saline solution. The preparation of the
patient, both before and during anesthesia, should include the same
scrubbing of and attention to the skin of the _back_ as that of the
abdomen, as there is much probability in any such case that posterior
drainage will be needed.
The _operation_ is begun as an exploration, through a median incision
above the umbilicus, some three inches in length, through which the
operator may inform himself as to the state of affairs within the
abdomen. Should fat necrosis be revealed, and first noticed in the
omentum, no doubt need be felt as to diagnosis. Any tumefaction by
which the stomach or colon is displaced, or the gastrocolic omentum
placed upon the stretch, calls for further and deeper exploration. The
upper abdomen should next be walled off with gauze and a small rent
made through the gastrocolic omentum; or it may in rare instances prove
wiser to push down an already depressed stomach, or more likely to lift
up the greater omentum and enter the lesser peritoneal cavity through
the mesocolon. In the majority of instances the condition can be best
appreciated and relieved by separating the stomach from the colon.
The condition may be one of extensive fat necrosis, disseminated,
but with its most abundant expressions in the neighborhood of the
pancreas, or there may be found evidence of extensive gangrene, the
pancreas itself sloughing and involved past any possibility of repair,
surrounded by disintegrating clot and debris; or there may be found a
more or less localized abscess, and perhaps evidences of putrefaction.
In at least two instances reported by Muspratt and Porter the pancreas
itself was not yet dead, but was so darkly discolored and swollen, as
well as so dense, that it was freely incised, the bleeding vessels
being tied and the clot removed. Both of these cases recovered. Such
incisions, if made in the gland, should always run parallel with the
duct and not across it. Whether pus be found or not will depend in
large degree upon the time that has elapsed since trouble began. It is
most desirable to expose the focus before pus has had time to form,
just as it is in acute appendicular disease.
The further operative treatment consists essentially in checking and
preventing hemorrhage, in removing all sloughing tissue which can be
safely taken away (and this may involve the greater part of the entire
gland), in disinfection of the cavity and general toilet of the upper
abdomen, with ample provision for drainage. This may be anterior
or posterior, and in bad cases should be both, unless procedure is
hastened by collapse. Posterior drainage is effected by having the
patient turned upon the right side, then making an incision 3 or 4 Cm.
long at the left costospinal angle, where, if the advice above given
have been followed, the skin will have already been prepared. Here the
outer border of the erector spinæ group of muscles is quickly exposed
and the blades of a pair of stout forceps entered and pushed toward
the inner cavity, within which the operator’s left hand is acting as a
guide. In this way it is possible to quickly insinuate the blades so
that the large vessels and the upper end of the kidney are preserved
from harm. A suitably prepared drain, preferably tubular, may then be
introduced deeply enough through the anterior wound to be seized by
the forceps and pulled through the tunnel made by their introduction.
It is thus drawn backward and outward to such an extent that its inner
end shall rest just where it is desired in the cavity of the lesser
peritoneum, the unnecessary external part of the drain being now cut
away. The whole procedure consumes but little time. Anterior drainage
will also be necessary, and the wound may then be closed.
It has been suggested to make the exploration as well as the drainage
from the loin, but this procedure cannot be here advised, since it
leaves too many features in doubt and affords insufficient means
whereby to appreciate and cope with many grave complications. Calculi,
either biliary or pancreatic, which are so often an exciting cause of
these troubles, should be carefully sought for and removed if present.
They could not be revealed nor removed through any small posterior
opening. Other good reasons are also advanced, since the intensity
of the symptoms is an expression of an intraperitoneal rather than
retroperitoneal lesion.
The reader will note that but little has been said as to the
distinction between the hemorrhagic, gangrenous, and other forms of
acute pancreatitis, as these are for the surgeon, as such, _side
issues_. _His paramount duty is to open the abdomen of every such case,
so soon as he can possibly effect arrangements._
=Subacute Pancreatitis; Abscess.=--Under this term are included disease
processes and lesions similar to or identical with those described
as causing acute and even fulminating expressions of pancreatic
obstruction, but less severe in their manifestations, less rapid in
their course, and more localized in their boundaries. They are often
so associated with a protective and natural walling off of the area
of excitement by barriers, which outpour of lymph and its consequent
condensation into adhesions afford, that they appear more often as
abscess of the pancreas or hematoma of the lesser cavity of the
peritoneum.
So far as concerns its etiology the causes are essentially the same as
in the acute cases, only the results are brought about more slowly,
weeks being in these cases as days in the others. Gallstones are by all
means the most common cause, and the pancreatic disease is itself an
expression of an infection travelling up its duct.
=Symptoms.=--The symptoms usually include pain, which, however, lacks
the agonizing intensity noted in the more acute cases. Vomiting is
usually associated with constipation, but the vomitus is rarely or
never bloody; jaundice of variable degree is a common feature, and
collapse is rare. Distention of the upper abdomen and tumor formation
come on more slowly. Tenderness is less extreme and muscle rigidity
less marked. While the pulse is less affected the temperature is
usually more so, often running high. Even early in the case we may
note general expressions of septic intoxication, such as mild chills
and a characteristic appearance of the tongue and face. Constipation
is followed by diarrhea; at least the stools which are fetid contain
blood, pus, fat cells, and undigested meat fibers. Pain is more or
less constant, but increased in paroxysms. Loss of appetite and rapid
emaciation are apparent from the outset. Albumin will be found in the
urine, but rarely sugar. The peculiar reaction described by Cammidge
will, according to Mayo Robson, give uniformly positive evidence. As
_abscess_ gradually or rapidly develops it will cause a swelling, which
has its origin behind the stomach and may displace this viscus, as
well as the colon, upward or downward, presenting usually toward the
abdominal wall. In rare instances the direction of least resistance
takes it toward one loin or the other, where it may appear as a
perirenal abscess, or around the crus of the diaphragm and above the
liver, where it would appear as a subphrenic abscess. It has been
known also to burrow along the psoas muscle and appear at the groin,
or even in the left broad ligament. Abscess of the pancreas may also
burst into the stomach, when pus will be vomited, or into the bowel,
whence it will be evacuated. A sudden relief, with disappearance of
tumor, followed by diarrhea and purulent stools, would indicate this
latter termination. Under these circumstances the abscess cavity may
repeatedly refill and reëmpty itself. Spontaneous recovery in this way
is possible, but septicemia and hectic usually persist until obviated
by operation.
=Diagnosis.=--The history, the evidently septic type of the case, and
the distinct signs above noted will make almost certain the presence
of pus, and Mayo Robson insists that the pancreatic reaction in the
urine (Cammidge) will make clear its location and origin; but, with or
without the latter, the important feature is that there must be a deep
collection of pus somewhere in the neighborhood of the pancreas.
=Treatment.=--This is necessarily operative, and in such cases as
those now considered there will be plenty of time afforded for all
the precautions known to careful surgeons. The aspirator should never
be used, at least not until the abdomen has been opened, then usually
with caution, lest pus escape along the needle track. The operation
is made as described above for the acute form of this disease. The
greatest care should be given to protecting the general peritoneal
cavity against infection. When adhesions to the anterior abdominal wall
are met they should be separated as little as possible, only to such
an extent as will permit direct approach to the collection below. Only
after the abscess cavity has been thoroughly emptied, disinfected, and
packed with gauze should the surgeon proceed to clear away or break
down adhesions so as to permit a suitable exploration of the lower
surface of the liver and the biliary passages.
And now perhaps comes the necessity for operative attention to these
latter, as one or many stones may be recognized in the gall-bladder or
the ducts. In this case there must be followed those general directions
elsewhere given in regard to the technique of operations upon the
gall-bladder and ducts. _Biliary drainage_ will in these cases be
nearly always indicated, for which a separate small opening in the
usual position may be made, if desirable, as it probably will be, for
one wishes usually to continue such drainage for several weeks, whereas
it is desirable to have a median incision heal as rapidly as possible.
The question of posterior drainage will also be raised. Ordinarily
it is of advantage, as the time required for anterior drainage can
be materially shortened, the abdominal wound be encouraged to close,
and because the natural effect of gravity is thus afforded. Moreover,
by it the whole period of confinement to bed may be materially
reduced. Therefore, unless the condition of the patient absolutely
contra-indicate, it will usually be a wise measure. In a few instances
it has been possible to drain a pancreatic abscess by a tube in the
common duct, after removal of the stone which has been obstructing
either it or the duct of Wirsung.
CHRONIC AFFECTIONS OF THE PANCREAS.
Chronic affections of the pancreas which interest the surgeon are:
1. _Interstitial pancreatitis_:
(_a_) Interlobular.
(_b_) Interacinous, leading to--
2. _Cirrhosis_ with accompanying diabetes.
3. _Neoplasms_:
(_a_) Cysts.
(_b_) Solid tumors.
4. _Calculi._
=Chronic Pancreatitis; Cirrhosis.=--The interlobular and interacinous
forms can both be considered under one heading so far as we are
concerned, their symptoms being similar, save that in the former the
compressed connective tissue by its presence causes atrophy of true
glandular elements, and thus by preventing their function interferes
with digestion; while in the interacinous type the proliferations of
this same sort of tissue invade the islands of Langerhans, impair
their glycolytic secretion or suppress it, and add a glycosuria to
those features common to both forms--moreover, their treatment is
essentially the same. In the advanced form of either type the pancreas
may be reduced in size and somewhat cirrhotic. This chronic affection
may be the result of an incomplete recovery from one of the more acute
conditions previously described; it may also have its origin in the
chronic irritation of the poisons of syphilis, typhoid, alcoholism,
and the like; but by far the most common causes are obstruction of the
pancreatic duct, either by biliary or pancreatic calculi, cicatricial
stenosis, the presence of tumors or the encroachment and erosion of
gastric ulcers and cancers. The morbid condition may involve the whole
gland or be localized, in the latter case particularly about its head.
=Symptoms.=--These should be studied with particular attention to the
case history, for a previous record of pain, cramps, chills, fever,
jaundice, very slight digestive disturbances, soreness, or local
tenderness will be suggestive and valuable if obtainable. As symptoms
gradually arrange themselves it will be found that tenderness over
the pancreas becomes constant, and is accompanied by at least a mild
degree of muscle spasm, that pain increases and is referred more
widely, often to the left side or even the scapula, while there may
be some fulness in the epigastrium. Dyspepsia and emaciation become
more marked. By the time the obstruction of Wirsung’s duct has become
complete, perhaps previous to it, fat and undigested muscle fibers will
be found in the stools, which are light-colored, bulky, and sometimes
contain blood. As pressure effects become more prominent evidences
of biliary obstruction, if previously lacking, present themselves;
the gall-bladder usually distends; the liver enlarges or may even
become cirrhotic from the irritation of pent-up toxic bile. Even the
spleen may become enlarged. In the urine sugar will be found in cases
of the interacinous type, though usually only at a late date; while
bile pigments are usually present and Cammidge’s test may reveal his
peculiar pancreatic reaction.
=Diagnosis.=--If the peculiar symptoms above rehearsed are present
diagnosis is not difficult. In many cases it is not easy to go beyond
the point of recognizing that both the pancreas and the biliary tract
are at fault, without deciding as to the exact degree of culpability
of each. The question of possible cancer arises in almost every one of
these instances. Should the ordinary pancreatic reaction in the urine
prove all that has been claimed for it, this grave problem can often be
settled previous to operation. If the operator satisfies himself by any
method short of actual operation that he has to do with cancer of the
pancreas, then operation may be considered inadvisable unless for some
special reason.
=Treatment.=--At least a reasonably long trial will usually be made,
in these cases, of medical, hydrotherapeutic, and other non-operative
treatment, with little or no benefit. When after appreciation of
the condition and intelligent treatment but slight relief accrues,
the case may be regarded (as it really is upon its commencement) as
surgical. Treatment, then, consists of _removal of the obstructing
cause by drainage of the biliary passages_. The operative procedure
will therefore take the form elsewhere described for this purpose.
Should deep exploration reveal no calculi it will be well to make sure
at least of the patulency of the ducts, by opening the gall-bladder or
common duct and exploring with the probe, or possibly even opening the
duodenum in order to do the same with the pancreatitic duct. Whether
calculi are discovered or otherwise a gentle stripping or massage of
the pancreas may be made to advantage. Biliary drainage should then be
established, and usually externally.
It has been difficult for the profession to appreciate why and how
these measures, which seem to be directed rather to the biliary
passages than to the pancreas, have given such brilliantly satisfactory
results as are everywhere reported. These are to be accounted for by
the facts that the primary cause most often lies in the former rather
than the latter, and is thus removed, and that one source of constant
irritation--namely, infected bile--is thus done away with, while
tension is removed and pancreatic juice again permitted to flow on as
it should; that a chronic toxemia (cholemia) is relieved, and that
physiological rest is afforded to the affected and disturbed organs.
When the operation is thus performed benefit may be expected; even when
done late it may be capable of great good.
NEOPLASMS OF THE PANCREAS.
=Cysts.=--In addition to _true cysts_ of the pancreas there have
been described so-called “_pseudocysts_” in the lesser peritoneal
cavity, and more or less surrounding the pancreas. They are rarely of
congenital origin, but are probably due rather to traumatism than to
any other cause. By many they have been likened to ranulas, or the
cysts which form in the salivary glands in consequence of obstruction
to ducts or their branches. Anything which obstructs any portion of the
pancreatic duct may lead to the formation of a retention cyst, the true
proliferation cyst--adenomas being practically unknown. That traumatism
figures so largely is due to the fact that injury is followed by
hemorrhagic extravasation, and this by more or less liquefaction or
degeneration, both of contents and of surrounding tissue, with the
secondary formation of a cyst whose walls are made of new connective
tissue.
A _true pancreatic cyst_ is a retroperitoneal tumor, while pseudocysts
are intraperitoneal. In front of the former lie four layers of
peritoneum, which may be completely merged together, but through which
a passage must be made when opening into it from the front. The
etiology of old pancreatic cysts may be completely concealed by the
changes which have slowly occurred since their origin. They may be
single or multiple, occur in any portion of the gland, and increase
even by coalescence. Within some of them, especially those of the duct
type, papillomatous excrescences may be found. The more distinctly
traumatic cysts occur perhaps oftener near the tail of the pancreas,
while into them repeated hemorrhages may take place, and the sac will
become quite thick, even exceptionally calcifying in places. These have
been described as _apoplectic cysts_.
Altogether, up to date, at least 150 of these cysts have been subjected
to operative intervention.
Pancreatic cysts contain a fluid which may be variously colored or
sometimes colorless, which is usually alkaline, and contains fat
globules, cholesterin crystals, blood crystals, albumin, and various
salts, most of these being evidences of their hemorrhagic origin. The
fluid may also contain the specific pancreatic ferments, of which the
diastatic is the more common, tryptic ferment being met occasionally,
while the fluid may also possess emulsifying properties. In size these
cysts vary from minute sacs to enormous collections of fluid.
As such a cyst attains marked size it will displace the adjoining
viscera, pushing the diaphragm upward and impeding heart and lung
action, obstructing the pylorus and duodenum and causing gastric
dilatation, pressing upon the intestines and perhaps even compressing
the ureters, thus producing hydronephrosis. Other peculiar pressure
effects may be met in particular instances. A sudden increase in size
indicates a fresh hemorrhage, which may lead to its rupture and to
death from peritonitis. These cysts rarely empty spontaneously into
the bowel. Their contents are liable to infection, and thus a cyst may
become converted into a large abscess.
=Symptoms.=--Symptoms include especially _pain_, which may have been
sudden, but becomes more or less constant, accompanied by a sense of
oppression, according to the size and the pressure effects produced
in each case. Digestion is always more or less disturbed; this may be
attributed to the stomach dilatation, which is itself a sequel of the
condition. The stools show little which is significant save that they
are occasionally bloody. Undigested muscle fiber would indicate loss of
pancreatic function. Other symptoms will vary so much with individual
cases that it is not necessary to consider them here.
The physical signs, coupled with a suggestive history, especially one
which includes an account of injury, are of the greatest importance
in diagnosis. These physical signs will include usually a yellowish
tinge of the skin, marked emaciation, dry skin, and the presence of a
tumor in the upper abdomen, which is usually centrally placed, but not
necessarily so. If the patient has carefully noted the development of
his own symptoms it will be found that the enlargement commenced above
and usually a little to the left, and developed in other directions
from that location. Palpation reveals a smooth, elastic, usually
fluctuating tumor, sometimes movable with respiration, rarely pulsating.
It must be remembered that a pancreatic cyst may rise above the
stomach, may rest entirely behind it, or may protrude either below
it and above the colon or else quite below the colon. Distention of
the stomach will afford accurate location, in these respects, upon
percussion, while percussion without distention may mislead. A tumor
which gives dulness below the stomach and above the colon is extremely
suggestive.
=Diagnosis.=--Diagnosis by aspiration is inadvisable, even dangerous,
for death has followed the introduction even of a needle into such a
cyst. Aspiration, then, should be reserved for tumors already exposed
through an abdominal incision.
For the purpose of _differentiation_ it will suffice here to remind
that tumors of the kidney, as well as hydronephrotic cysts, grow
downward and forward from the loin, and can be pushed backward to
their proper place unless too large, that they are not accompanied
by digestive disturbances, while the urine is usually more or less
indicative. A hydronephrotic cyst can scarcely be made to occupy a
position between the stomach and the colon and present in the middle
line in front. Ovarian cysts rise from the pelvis and will rarely
occur in the upper location, save those provided with extremely long
pedicles. Hydatid cysts of the liver show a continuity and fixation to
that viscus which are usually diagnostic.
=Treatment.=--The only treatment for pancreatic cysts is surgical,
it remaining with the surgeon to decide as between _drainage_ and
_extirpation_. While it is indisputable that extirpation is the ideal
method of dealing with all cysts and tumors, most of these cases are
of such long duration that the adhesions contracted between their
exteriors and the surrounding viscera are so dense and firm that
much greater danger attaches to a radical operation than to one for
simple incision and drainage. I have been able in at least one case to
completely extirpate such a cyst, but it was one exceedingly favorably
situated and surrounded.
_Incision and drainage_ may be effected in one operation or in two
sittings, and as between them it must be decided according to the
merits of the case. It is undesirable to permit the escape of the
contents of these cysts into the abdomen. In some instances, therefore,
it would be much better to make a small abdominal incision and through
it attach the surface of the cyst to the margins of the parietal
peritoneum, reserving the actual opening into the tumor until a day
or two later, when it may be expected that firm adhesions will have
attached the sutured surfaces. In this way any leakage within the
abdomen may be avoided. Care must be exercised, even in such cases,
as a large cyst too suddenly emptied may cause sudden displacement of
the heart or of other viscera, which would not be to the advantage
of the patient. In this case fluid could be withdrawn in portions as
desired, or, making a small opening, one could arrange for its gradual
escape. On the other hand, there are cases where it would be of great
advantage, if the cyst could not be emptied, to so open it as to permit
posterior drainage to be made, by which the period of recovery would be
much abbreviated.
No case of this kind can be treated without drainage, the explanation
being that the cyst being emptied will collapse, its walls coming
into more or less close contact with each other, that the presence
of drainage material will provoke exudate and the formation of
granulation tissue, and that a complete obliteration will thus in
time occur--but drainage in the natural direction of gravity as the
patient lies upon the back will permit of much more speedy fulfilment
of one’s hopes; hence its advantage. Better still, perhaps, would be
through-and-through drainage, with such irrigation as might be needed,
practised daily, or oftener if necessary.
=Tumors of the Pancreas.=--While _sarcoma_ and other forms of malignant
disease, as well as _adenoma_ of the pancreas, have been described,
they require no special consideration here, since the surgeon has so
rarely to do with anything of this character save _adenocarcinoma_ of
the pancreas. This is a disease of middle or advanced life, more common
in males than in females, usually of scirrhous type, and localized,
though it may appear in softer forms or be disseminated. It takes
its origin from the epithelial cells lining the acini and the ducts.
Metastasis is common and direct extension by continuity most easy and
frequent. It is made known by its pressure effects rather than by any
other important signs or constant features. It has been known to lead
to chylous ascites.
It is difficult in many exploratory operations to decide as between
a chronic induration or cirrhosis of the pancreas and that due to
cancer, and, in fact, in certain cases it may be impossible to clear
up the difficulty, leaving it to be solved either by recovery or death
in consequence of extension of malignant disease. Thus when operating
for biliary obstruction, where the parts are surrounded by adhesions
and the organs are only indistinctly palpable, it may be impossible
to decide as to the nature of a hard mass felt in the head end of the
pancreas, especially when other distinct expressions of cancer are
absent.
_Cancer of the pancreas_ is at present a primarily hopeless disease,
and is of interest to the surgeon only in that some of the most
distressing features which it causes may be temporarily relieved by
biliary drainage. The symptoms which will bring such a patient to him
will be essentially those of biliary obstruction, perhaps with the
accompaniment of glycosuria or the discovery of fat in the feces.
Neither of these, however, is an invariable symptom. Diarrhea is but an
occasional feature, and colorless stools may be discharged when there
is no jaundice. A perfectly painless progressive (bronzing) jaundice,
with distention of the gall-bladder, would perhaps more than any other
single feature indicate pancreatic cancer. When such a growth has
attained a size sufficient to make it discoverable on palpation it
might be mistaken for a biliary cancer, from which it would have to be
differentiated especially by the movability usually noted in the latter.
The only treatment for pancreatic cancer is operative, and consists in
_drainage of the gall-bladder_, and after a manner elsewhere described
in the section on Diseases of the Biliary Passages.
PANCREATIC CALCULI.
From the true pancreatic secretions precipitations of mineral salts,
combined with organic elements, may occur, just as from the saliva,
the latter thus furnishing the salivary calculi elsewhere described,
the two varieties having many points of resemblance. Again, calculi,
evidently of biliary origin, may be met with in the pancreatic duct.
The former consist largely of calcium oxalate, combined with calcium
carbonate and phosphate. They may be single or multiple, and vary
greatly in size up to that of a robin’s egg. Hypothetical calculi, with
consequent duct obstruction, have been held to be responsible for many
pancreatic cysts. Thus one may explain cyst formation, even though no
calculi be found at the time of operation.
Calculi reposing within the structure of the pancreas have much to
do with the acute and subacute, as well as the more chronic types
of pancreatitis, the latter when they act alone, the former when to
their essential disturbances are added the possibilities of bacterial
infection.
When pancreatic calculi produce symptoms they resemble those of
cholelithiasis, causing paroxysmal pain, with vomiting, and perhaps
transient jaundice. Glycosuria is an occasional feature.
The condition is rarely diagnosticated previous to operation. Should a
calculus be met in this location during the progress of any operation
it should be removed by an incision made parallel to the duct, with
such closure of the wound in the pancreas as can be subsequently
effected and with ample drainage of the deep wound, in order that
pancreatic fluid may not escape into the peritoneal cavity. If
encountered during operation for pancreatic cyst the same advice will
apply.
CHAPTER LIV.
THE KIDNEYS.
CONGENITAL ANOMALIES AND DEFECTS OF THE KIDNEYS.
Recent embryological studies have established the fact, in regard to
the kidneys, and given rise to the inference in regard to the other
viscera, that the primary cause of congenital variations has much to
do with the earliest development of the bloodvessels. The general
inclination has been to view the vessels as following the organs.
This should be reversed, as we are now learning that organs develop
_around the bloodvessels_, and that so-called congenital variations
arise from departures of vascular arrangement from the ordinary types.
Without pursuing this subject further it is sufficient to say that,
aside from defects of such character that the newborn infant can live
but for a few hours or days, those which have most surgical interest
mainly comprise variations in number and in size, including every
possible combination, from _absence of an entire kidney_ to _horseshoe_
forms, and various anomalies of the _ureters_ including _defects_ and
_redundancies_, _double ureters_, and the like. While _supernumerary
renal tissue or kidneys_ are extremely rare, the presence of
supernumerary _adrenal_ tissue in one or both kidneys (even in
adjoining organs) is not uncommon. Here it may lead to the development
of a distinct form of tumor, _hypernephroma_, which will be discussed
later. The complication of absence of an entire kidney is sufficient to
give it actual surgical importance, since it has repeatedly happened
that the remaining kidney has been removed for disease, the inference
being that its work could be carried on by its fellow, which proved to
be lacking. This accident might be prevented by a careful cystoscopic
examination. Nevertheless the rarity of this condition permits it to
be almost excluded from ordinary consideration. After removal of one
kidney the other undergoes compensatory physiological enlargement and
does double duty, if indeed this has not already occurred.
_Acquired defects_ may be due to intrinsic or extrinsic causes, _e.
g._, disease within the renal structures or ureters, or lesions
in adjoining organs and tissues, producing mechanical or other
disturbances. Thus the functionating capacity of one or even both
kidneys may be seriously compromised by either internal or external
conditions, and it behooves the surgeon to estimate the degree of renal
disability or inadequacy before operating upon either of these organs.
On the other hand if the disease be confined to one kidney he may feel
that it is doing so little good and so much harm that the patient will
be really relieved by its removal. Nearly everything, then, depends
upon a determination of the precise existing conditions. They should be
ascertained by means of the catheter, the cystoscope, the microscope,
and by the careful _chemical_ study of the urine. These methods have
been developed into a specialty of considerable complexity, but of
great practical importance. The surgeon should not fail to employ
them. If he is not familiar with the technique he should seek special
assistance.
[Illustration: FIG. 632

INJURIES TO THE KIDNEYS.
Although the kidneys lie in a protected position they are not
infrequently injured, both by contusions and by penetrating wounds.
From the latter blood will escape externally. In the former it can
only extravasate when the cortex and capsule are torn, or escape
through the ureter into the bladder, when it will be seen in the urine,
which, however, may have to be drawn by the catheter on account of
retention. _Blood in the urine after a local injury denotes serious
mischief inside the kidney or along the urinary tract._ If continuing
for several hours, but especially if accompanied by local indications,
swelling or other evidences of extravasation, by muscle rigidity or
by severe pain, with general symptoms, it should be assumed that
these fluids are escaping into the perirenal tissues, perhaps into
the peritoneal cavity, and that an immediate exploratory operation
should be urged. When once this indication is clearly recognized the
condition brooks no delay. The same is true of penetrating wounds. On
general principles, with a patient in such a condition and showing
no improvement, or especially if the reverse, _exploration offers
the safer course_ in by far the greater number of cases. The surgeon
need only convince himself that such blood as the urine contains does
not come from the lower tract, but rather from the kidney or ureter.
_Exploratory nephrotomy_ is by itself so harmless that one need never
hesitate to urge it. A kidney found slightly lacerated may be repaired
with sutures, while one found seriously disorganized should either
be sutured and drained or totally removed, as the case may require.
There is little room for doubt that it is better to institute such a
measure early rather than to permit the dangers and even ravages of
infiltration of blood and urine. In fact it may almost be laid down as
a precept that _every patient who has received an injury in the loin or
flank and who repeatedly passes blood in the urine should be explored_.
PAIN IN THE KIDNEY; NEPHRALGIA.
This is a vague term, implying pain or neuralgia in the kidney, and can
refer only to symptoms, not to any particular disease. Yet it must be
confessed that for certain cases of so-called nephralgia no physical
cause is easily discovered. Pain in the kidneys--or, as patients will
often say, in the back--may be associated with excess of oxalic and
uric acids and salts in the urine, and is then relieved by a steady
course of alkaline diuretic treatment, with plenty of fluid, the
severe pain being combated with aspirin. Nephralgia may be expected in
connection with many renal disorders, but the term should ordinarily be
confined to cases of pain without known cause.
When such pain is uncontrollable and intolerable the indication is to
make an exploratory operation, by which the kidney should be at least
exposed, perhaps delivered upon the external surface of the body, and
carefully examined. Its capsule should be split (capsulotomy), as
Harrison and others have suggested, and if on palpation or needling
(using a needle as a probe) there be any good reason for opening it
this may be done, so that with the finger its pelvic cavity may be
carefully explored, in order to find any previously unrecognized
calculus or other surgical lesion. The mere operation of _capsulotomy_
or capsule splitting has proved of such great value that I always
practise this measure upon any kidney which for any reason it may seem
wise to expose.
INFLAMMATIONS AND INFECTIONS OF THE KIDNEYS.
Under this head it is intended to consider (1) acute or subacute
specific infections of the upper urinary passages, due to bacteria,
with the effects of which we are familiar, _i. e._, septic, gonorrheal,
and tuberculous lesions, and (2) chronic nephrites of irregular or
uncertain type, for which operative treatment has been recently
proposed.
