The mortality from abscess of the liver is very large. In Rouis's

collection of 203 cases, 162 died, 39 recovered entirely, and 2

improved; 80 per cent., therefore, proved fatal. According to De

Castro,[111] whose observations were made at Alexandria, Egypt, 93 in

208 cases died, this being 72.5 per cent. According to Ramirez,[112] of

11 cases of which an account is given in his memoir, 10 died and 1

recovered--a mortality of 90 per cent. De Castro (p. 40) also gives the

results arrived at by the Medico-chirurgical Society of Alexandria, who

collected 72 cases of abscess, of which 58 died, making the percentage

of deaths 80.5. Various circumstances besides the abscess affect the

result. An early successful operation, the mode of discharge, the

amount of hepatic tissue destroyed by the {1018} suppuration, the

extent of pre-existing lesions--especially ulcerations of the

intestinal canal--are important factors in the result. In respect to

some of these we have valuable statistical data. The discharge through

the lungs is the most favorable route, next by the parietes of the

abdomen, and lastly by the intestinal canal. One-half of those cases in

which discharge is effected by the right lung get well. This is my own

experience, and it accords with the observations of Rouis, of De

Castro, and others. Rouis gives the result in 30 cases of hepatic

abscess discharging by the right lung; of these 15 recovered. Of 25

cases observed by De Castro, discharging by the lungs, 19 recovered.

Next to the discharge by the bronchi, the most favorable mode of exit

is externally, through the parietes of the abdomen; much less favorable

is by the stomach or intestine; but still more fatal is the discharge

into the cavity of the peritoneum. When the abscesses are multiple and

due to pyæmia, the termination is always in death. The numerous lesions

besides the hepatic accelerate the fatal issue. In the case of large

single abscesses the result is in a great measure due to exhaustion

from protracted suppuration. When in addition to the formation of a

great quantity of pus there is frequent vomiting and rejection of

aliment, the failure of strength is proportionally rapid. In favorable

cases, after an abscess is evacuated through the right lung, recovery

takes place promptly. When the discharge occurs through the abdominal

wall, the process is much slower, and often fistulous passages with

several orifices, very slow to heal, are formed. Complete recovery may

ultimately take place. The recovery will be incomplete in those cases

with large loss of hepatic substance, especially when this coincides,

as it usually does, with catarrh, ulceration, and other lesions of the

intestinal tube. Again, the recovery will be incomplete in those cases

where there are imperfect healing of the abscess site and a fistulous

communication with the exterior.

[Footnote 111: _Des Abcès du Foie des Pays chauds, et de leur

Traitement chirurgical_, _loc. cit._, p. 40, Paris, 1870.]

[Footnote 112: _Du Traitement des Abcès du Foie, Observations

receuilles à Mexico et en Espagne_, par Lino Ramirez, M.D., Paris,

1867, _loc. cit._]

It is possible for the arrest and healing of a suppurative inflammation

of the liver to take place without discharge. Under such circumstances

the watery part of the pus is absorbed, the solid constituents undergo

a fatty metamorphosis, are emulsionized, and thus absorbed, and

gradually closure of the damaged area is effected by a

connective-tissue formation. We must, however, accept with caution

those examples of this process which are supposed to have occurred

because radiating cicatrices are discovered on the surface of the

liver. In a case of hepatic abscess discharging through the lung, known

to the writer, after death, which occurred fifteen years subsequently,

there was no trace of the mischief, so perfectly had repair been

effected. Radiating cicatrices are so often of syphilitic origin that

they cannot be accepted as proof of the former existence of an abscess.

DIAGNOSIS.--He who finds the diagnosis of abscess of the liver easy

under all circumstances can have had but little experience with the

numerous difficulties in the way of a correct opinion. There are cases

so plain that the most casual inspection suffices to form a conclusion;

there are cases so difficult that the most elaborate study fails to

unravel the mystery. The maladies with which hepatic abscess may be

confounded are echinococcus of the liver, dropsy of the gall-bladder,

cancer, abscess of the abdominal wall, empyema, or hydrothorax, etc. As

regards echinococcus, the difference consists in the slow and painless

enlargement characteristic of echinococcus, and the absence of any

symptoms other than those {1019} due to the mere pressure of the

enlarging mass. In abscess there may be no apparent enlargement, or the

increase in the area of dulness may be very great, or after a period of

increase of size there may be contraction due to the formation of pus,

and hence limitation of the inflammation; finally, the accumulation of

fluid may be sufficient to cause dulness up to the inferior margin of

the second rib. There are no corresponding changes of size in the

echinococcus cyst. Furthermore, abscess of the liver large enough to be

recognized by the increased dimensions of the organ will be accompanied

by more or less pain in the right hypochondrium and by a septicæmic

fever. On the other hand, an echinococcus tumor is not accompanied by

fever, pain, or tenderness, and it has that peculiar elastic trembling

known as the purring tremor. The most certain means of differential

diagnosis is the use of an aspiration-needle and the withdrawal of a

portion of the fluid. The presence of pus with hepatic cells will be

conclusive of abscess, whilst a serous fluid with echinococci hooklets

will prove the existence of the echinococcus cyst.

In cases of dropsy of the gall-bladder there are no febrile symptoms,

no chills, and the tenderness when present is limited to the pyriform

body, the seat of the accumulation of fluid, and no general enlargement

of the liver can be made out. At the point of swelling fluctuation may

be detected, or if the gall-bladder is filled with calculi the

sensation imparted to the touch is that of a hard, nodular body of an

area and position corresponding to that of the gall-bladder. Tapping

the gall-bladder, an easy and safe procedure, will resolve all doubts.

When an impaction of a gall-stone is the cause of abscess, the clinical

history is eminently characteristic: there are attacks of hepatic

colic, after one of which the chills, fever, and sweats belonging to

hepatic abscess occur.

The differentiation of cancer of the liver from abscess rests on the

following considerations: In cancer there is slow enlargement, with

pain; a more or less nodular state of the organ without fluctuation;

usually ascites; no rigors; no fever and sweats. In abscess the liver

may or may not be enlarged; there are rigors, fever, and sweating, and

the surface of the organ, so far as it can be reached, is smooth and

elastic, and it may be fluctuating. Cancer happens in persons after

middle life, develops very slowly, and is accompanied by a peculiar

cachexia; abscess occurs at any period, very often succeeds to or is

accompanied by dysentery and by the usual phenomena of suppuration.

It is extremely difficult to separate an abscess in the abdominal wall,

in the right hypochondrium, or a tumor in this region, from an abscess

of the liver. The history of the case, the existence of a dysentery or

of an apparent intermittent or remittent fever before the appearance of

a purulent collection, will indicate the liver as the probable source

of the trouble. Attention has already been called to a case in which an

abscess of the liver was supposed by an eminent surgeon to be a tumor

of the abdominal wall. The history in this case of an obstinate

remittent fever, followed by the appearance of a tumor of the

hypochondrium and by a preliminary discharge at the umbilicus, clearly

indicated the nature of the trouble. In the absence of any history of

the case it is extremely difficult to fix the origin of a suppurating

tumor originating, apparently, in the depth of the right hypochondrium.

Mistakes are frequently made in the case of an abscess developing in

{1020} the convexity of the right lobe of the liver and pushing the

diaphragm up to the third, even to the second, rib, and thus producing

conditions identical with empyema of the right thorax. Such instances

of hepatic abscess are peculiarly difficult of recognition, because,

the physical signs being the same as those of empyema, the

differentiation must rest on the clinical history. In cases of empyema

proper the effusion in the chest is preceded by pain and accompanied by

an increasing difficulty of breathing; in hepatic abscess there are, as

a rule, symptoms of disturbance in the hepatic functions, fluctuation

in the hepatic region, dysentery, etc., long anterior to any

disturbance in the thoracic organs. Again, empyema may be a latent

affection, without any symptom except some obscure pain and a

progressive increase in the difficulty of breathing; on the other hand,

abscess of the liver is preceded by symptoms of liver disease and of

associated maladies. A dry, purposeless cough is present in many cases

of abscess; a painful cough with bloody expectoration occurs when

preparation is making for discharge through the lungs.

Errors of diagnosis are liable to occur in the consideration of

symptoms unquestionably hepatic in origin. Thus, the intermittent fever

accompanying some cases of hepatic colic, like the shivering fits and

fever which occur in cases of nephro-lithiasis, may be confounded with

the septicæmic fever of hepatic abscess. An attentive examination of

the attendant circumstances, especially a careful survey of the right

hypochondrium, can alone determine the nature of the symptoms. In all

doubtful cases the experimentum crucis of puncture with the

exploring-needle becomes a measure of necessity. When all diagnostic

indications are at fault, the needle of the aspirator may decide the

issue. An abundant experience has shown that a needle of suitable size

may be introduced into the right lobe without any ill result--often,

indeed, with distinctly good effects when there is no suppuration or

when pus cannot be detected. In the present state of our knowledge it

cannot be determined why puncture of the organ should be beneficial in

cases having the symptomatic type of hepatic abscess when none exists;

but of this fact there is no doubt.

TREATMENT.--As the formation of pus is coincident with or causative of

the first symptoms, it is obvious that treatment directed to prevent an

abscess can rarely succeed. Yet it is probable that now and then an

abscess just forming has been arrested and healing effected. At the

onset of symptoms some large doses of quinine, with a little morphine

(scruple j of the former and 1/8 gr. of the latter), every four or six

hours, may have a decided curative effect. During the course of the

septicæmic fever, with its chills and febrile exacerbations, quinine in

full doses and alcohol according to the conditions present are

necessary remedies. As the symptoms develop saline laxatives are useful

until the formation of pus becomes evident, when all perturbating

treatment of the intestinal canal should cease. If dysentery be present

when the hepatic symptoms arise, it should be cured as promptly as

possible; and of all remedies for this purpose, ipecac given in the

usual antidysenteric quantity offers the best prospect of relief. For

the dysentery which succeeds to abscess, and is probably, in part at

least, dependent on portal obstruction, the mineral astringents, as

copper sulphate, are the most effective remedies. As far as

practicable, after an abscess has formed the intestinal canal should be

kept quiet, for any considerable disturbance will {1021} endanger the

escape of pus into the peritoneal cavity. Persistent vomiting is very

significant of pressure by an enlarging abscess in the stomach, and

usually signifies an abscess associated with impacted calculus. It is

important in such cases to maintain, as far as can be done, a quiescent

condition of the stomach, for the purpose of preventing rupture into

the peritoneal cavity and to favor the nutrition which is seriously

endangered by the repeated vomiting. Effervescent soda powders are very

useful; carbolic acid in solution, or creasote-water with or without

bismuth, is beneficial; champagne, very dry and highly effervescent,

has been, in the writer's hands, remarkably efficient. As food becomes

a most important need in such cases, milk and lime-water, wine-whey,

egg-nog, and similar aliments must be given in small doses and

frequently. Nutrient enemata, prepared from eggs, milk, and beef-juice,

with the materials for digestion--acid and pepsin--may be made to

supplement the stomach, but such efforts have a very limited utility,

owing to the state of the hepatic functions and to the obstruction of

the portal circuit. In all cases it is necessary to maintain the

strength by suitable aliment and the judicious use of stimulants. The

long-continued and profuse suppuration makes an enormous demand on the

vital resources of the patient, and this must be compensated by

suitable food-supplies.

As the formation of pus has taken place in most cases when symptoms

have begun, the question of highest importance is, Shall the pus be

evacuated? The statistical evidence relating to this question becomes

then an extremely valuable guide. As in almost all cases of puncture of

the liver for the evacuation of an abscess some part of the liver

substance must be passed through, it is necessary to note how far this

can be done without inflicting permanent injury on the organ. Hammond

has punctured the liver in eight cases without the presence of an

abscess, and of these not one has presented any unfavorable symptom.

The author has punctured the liver, penetrating well into the interior,

in two cases in which no abscess was discovered, but the symptoms of

hepatitis existed, with the effect to improve the symptoms. In

Condon's[113] collection of 11 cases there were 8 of abscess evacuated

by the trocar, and 3 of acute hepatitis in which abscess had not

formed, but in which the puncture procured the most decided

amelioration of the symptoms. We have heretofore referred to Hammond's

experience in the puncture of the liver in cases of hypochondriasis,

this condition appearing to depend in some instances on the presence of

abscess. In a number of instances abscesses did exist, but in many

others there was no apparent lesion of the liver, but in these cases

the puncture of the organ was without any ill result. Testimony to the

same effect is given by Ramirez,[114] who asserts that he had not known

a single instance in which any ill result followed puncture of the

liver. It may therefore be regarded as certain that exploratory

puncture of the organ for the purpose of diagnosis as well as for

treatment can at any time be performed with suitable precautions in

respect to the size, condition, and character of the instrument.

[Footnote 113: "On the Use of the Aspirator in Hepatic Abscess," Dr. E.

H. Condon, _The Lancet_ (London), August, 1877.]

[Footnote 114: _Du Traitement des Abcès du Foie, Observations

recueilles à Mexico et en Espagne_, par Lino Ramirez, M.D., Paris,

1867, p. 65.]

The authorities of most experience are agreed that, provided with the

{1022} aspirator, the abscess may be punctured as soon as a purulent

collection can be ascertained to exist. The obvious reason for tapping

the abscess is its tendency to extend in various directions, destroying

the hepatic substance. In those examples confined by a limiting

membrane, after a time of inactivity ulceration begins, and the pus

seeks an outlet in some direction. The early evacuation by a suitable

aspirator becomes then a measure of the highest necessity. The good

effects of puncture with even such a crude instrument as the trocar is

well exhibited in the statistics collected by Waring.[115] In a

collection of 81 cases opened by the knife or trocar there were 66

deaths, making the percentage of recoveries 18.5. In these cases the

operative procedure was a final measure, and the mischief had been done

almost if not quite in its entirety. The statistics of Waring are

concerned with a period anterior to 1850. Although they demonstrate the

value of the trocar and evacuation of the abscess, as compared with the

results of the natural course of the disease, the far greater success

of the treatment by the aspirator is shown by the statistics of recent

times. Thus in McConnell's[116] 14 cases, also of India, in which the

aspirator was used to empty the sac, 8 recovered and 6 died. The

statistics of Waring may also be profitably compared with those of

Condon,[117] in which, of 8 cases of abscess evacuated by the

aspirator, 4 recovered, or 50 per cent. They may also be compared with

Sach's[118] cases, 21 in number, of which 8 recovered, or 38 per cent.,

and with the cases of De Castro[119] of Alexandria, who reports 22

large abscesses operated on, the proportion of cures being 31.8 per

100, and 10 small abscesses, the proportion of cures being 70 per 100.

In a case seen in consultation with Collins, in this city, last year,

the aspirator was used by us about three months after the symptoms of

abscess declared themselves. About a quart of bloody pus was drawn off

at once, the opening sealed, and no subsequent accumulation occurred,

the patient entirely recovering, for after a year he was seen

(December, 1884) in complete health. From these data we draw the

important conclusion that early operation is desirable. This fact may

be formulated in the expression: In all cases of hepatic abscess use

the aspirator whenever the presence of pus is made out. When the

abscess is large, and especially when communication is established with

the parietes of the abdomen, a free opening, followed by the insertion

of a drainage-tube, is the proper method to pursue. If the pus

reaccumulates, it is good practice to inject the cavity with tincture

or compound solution of iodine after the pus is drawn off, provided the

dimensions of the abscess are not too great.

Liver_, _loc. cit._]

of the Liver treated by this Method," _Indian Annals of Medical

Science_, July, 1872, quoted.]

Traitement chirurgical_, par le Docteur S. V. de Castro (d'Alexandrie

d'Egypte), Paris, 1870, p. 59.]

As regards the mode of proceeding, the following are useful rules:

Ascertain, if possible, the existence of fluctuation; locate the point

where the walls of the abscess are thinnest; insert an

exploring-needle, and if the dépôt of pus is reached substitute a

trocar having a sufficient calibre to evacuate the contents of the

abscess; observe antiseptic precautions in respect to each detail of

the operative procedure, and after the removal of the canula or needle,

if a drainage-tube is not necessary, close the {1023} wound

antiseptically. If drainage is necessary, keep the cavity empty and use

proper solutions to prevent septic decomposition. When an abscess of

the liver is pointing, the best place to puncture is where the abscess

is most prominent and it walls thinnest, but if the accumulation of pus

is encysted and there is no attempt at effecting an exit, the

exploring-needle should be passed into the interior of the right lobe,

the most usual site of suppuration. If pus be reached, a larger trocar

may be inserted to evacuate the cavity thoroughly. Repeated insertion

of the needle-trocar is preferable when the abscess is small, but when

the accumulation is large and sufficiently firm attachments to the

abdominal parietes exist, a drainage-tube will be necessary.

In what direction soever discharge of an abscess may take place, the

general indications are to support the powers of life by food and

stimulants. The utmost quietude should be maintained. It is useful, by

the application of a firm flannel bandage, to keep the liver in its

proper position and maintain it there. When pointing of an abscess

occurs, a large flaxseed poultice is a soothing and a mechanically

supporting application.

Acute Yellow Atrophy.

DEFINITION.--By the term acute yellow atrophy is meant an acute

affection of the liver, characterized by rapid wasting or degeneration

of the organ, accompanied by the systemic symptoms belonging to an

acute acholia or cholæmia. It is an acute, diffused inflammation, with

atrophy of the proper gland-elements. It has been called icterus

gravis, malignant icterus, hemorrhagic icterus, malignant jaundice,

etc.

HISTORY.--Cases having a more or less exact resemblance to acute yellow

atrophy have been occasionally reported from the earliest period.

Amongst English physicians, Bright[120] was one of the first to give an

accurate account of the clinical history of some well-defined cases.

Rokitansky[121] was really the first to define the disease from the

pathological standpoint, and it was he who designated it acute yellow

atrophy, this term being intended to signify the nature of the

objective changes. The first treatise ever published on the disease as

a distinct morbid entity was the monograph of Horaezek,[122] which

appeared in 1843. Amongst the French, Ozonam in 1847 was the first to

recognize and describe the disease as a distinct affection, although

Andral[123] had several years before mentioned an affection of the

liver which corresponded in some of its features to this affection. In

1862, Wagner[124] asserted that many of the cases of acute yellow

atrophy were only examples of acute phosphorus-poisoning, and that no

real distinction exists between the two affections. This statement has

been warmly disputed by various German observers, but there is no doubt

a close resemblance between the two affections.

[Footnote 120: _Guy's Hospital Reports_, 1836, vol. i. p. 621.]

[Footnote 121: _Handbook of Pathological Anatomy_, Am. ed.]

[Footnote 122: Quoted by Legg, _On the Bile, Jaundice, and Bilious

Diseases_, _loc. cit._]

[Footnote 123: _Clinique médicale_, 1839, tome ii. p. 363.]

[Footnote 124: _Archiv der Heilkunde_, 1862, p. 364.]

CAUSES.--There can be no doubt that acute yellow atrophy is a very rare

disease, since so few examples are found post-mortem. In the course of

a very large experience in autopsical examinations I have met with but

{1024} one characteristic example.[125] According to Legg, it is "one

of the rarest diseases known to man."

[Footnote 125: _General Field Hospital_, December, 1863.]

Several theories have been proposed to explain the occurrence of this

affection, but without success. It has been ascribed to an excess in

the production of bile, to stasis in the bile, and to a sudden

saturation of the hepatic cells with biliary matters contained in the

portal vein. That these supposed causes are really influential in

producing the malady can hardly be entertained. That there is a

peculiar poison which has a causative relation to the disease is

rendered probable by the fact that a condition closely allied to this

disease is produced by phosphorus, antimony, arsenic, and other

poisons. Is it not a ptomaine generated under unknown conditions in the

intestine? Especially does the morbid anatomy of phosphorus-poisoning

nearly agree in all its details with icterus gravis--so nearly that by

many German authorities they are held to be identical.

Age has a certain influence in the causation of this disease. It is

rarely seen in early life, Lebert in a collection of 63 cases having

found only 2 before ten years of age, yet there has been a well-marked

case at three, and Hilton Fagge reports one at two and a half years of

age. Nevertheless, much the largest number occur between fifteen and

twenty-five years of age, and the maximum age may be fixed at sixty.
