CAUSES.--Sclerosis of the liver is, conspicuously, a disease of adult

life and onward. Except the congenital example mentioned below, the

earliest age at which the disease has occurred, so far as I am able to

ascertain, is four years--a case reported by Wettergreen[51] of

hypertrophic sclerosis, in which neither a syphilitic nor paludal cause

could be ascertained. Cayley[52] reports a case in a child of six;

Murchison,[53] Frerichs,[54] Griffith,[55] one each at ten. After this

period the increase relatively to age is rapid. The majority of cases

occur between thirty {991} and fifty years. Yet Virchow[56] has given

the details of a congenital example. According to Förster, of 31 cases

of cirrhosis, 16 were between forty and sixty years. The preponderance

of cases in the male sex is very decided. Of Bamberger's 51 cases, 39

were men, 12 were women; of Frerichs' 36 cases, 20 occurred in men and

16 in women--a larger proportion of women than any other author

records; of 12 cases observed by myself, only 1 was a woman.

Nationality does not affect the production of cirrhosis, except as

regards the personal habits of the people. This disease is

comparatively uncommon in wine- and beer-drinking countries, and

frequent amongst a spirit-drinking people.[57] The great etiological

factor is the abuse, the habitual use, of spirits, and hence the number

of cases observed in North Germany, England, Scotland, and the United

States. Murchison affirms that he has never seen a case produced in any

other way. Even in children of tender years the abuse of spirits can

usually be traced. Nevertheless, there are instances of the disease the

origin of which cannot be referred to alcoholic excess. The congenital

cases, as that narrated by Virchow, and the instances occurring in

children and adults not given to spirits in any form, indicate that

there are other pathogenetic influences which may bring about a

sclerosis of the liver. Virchow[58] was one of the first to illuminate

the subject of visceral syphilis and to demonstrate the occurrence of

sclerosis of the liver from syphilitic infection. Very often the

syphilitic cachexia coincides with alcoholic excess. There can be no

doubt that chronic malarial poisoning causes, or powerfully predisposes

to, cirrhosis. I have submitted elsewhere pathological evidence on this

point,[59] and the Italian physicians, who have the opportunity to

obtain accurate data, maintain that malarial toxæmia does bring about

this state. It is probable that the overgrowth of connective tissue is

induced by the repeated congestions of the malarial attacks, and by the

obstruction due to catarrh of the bile-ducts which so often occurs in

the febrile paroxysms.

[Footnote 59: _Memoirs of the Sanitary Commission_, medical volume.]

J. Wickham Legg[60] and Charcot[61] nearly simultaneously discovered

that obstruction of the bile-ducts, if continued a sufficient length of

time, sets up a hyperplasia of the connective tissue of the liver. The

evidence is pathological and experimental. Thus, Legg has seen a liver

markedly cirrhotic in a case where a small cancer of the duodenum

completely obstructed the flow of bile into the intestine.[62] By tying

the common duct in dogs it was found that a hyperplasia of the

connective tissue very soon occurred, and this was followed, of course,

by contraction of the new tissue and atrophy of the hepatic cells.

Closure of the hepatic vein has the same effect, and also, as

Solowieff[63] has asserted, closure of the portal vein; on the other

hand, by Frerichs and others the closure of the portal is attributed to

the sclerosis.

[Footnote 63: _Arch. f. path. Anat., etc._, Band lxii. p. 195.]

Certain poisons, as antimony, arsenic, notably phosphorus, have the

power to set up an irritative hyperplasia of the connective tissue of

the {992} liver. These metals accumulate in the liver in preparation

for excretion. Wegner,[64] in the study of the action of phosphorus on

dogs, rabbits, and other animals, has induced a marked degree of

sclerosis, but such results have not been observed in cases of

poisoning by phosphorus in man, except in an instance reported by

Küssner.

[Footnote 64: _Virchow's Archiv_, Band lv. p. 18.]

Finally, a condition of the liver corresponding in all respects to

cirrhosis has been induced by perihepatitis, by the organization of the

exudation and its subsequent contraction, and by the extension of the

morbid process from the capsule to the interlobular connective tissue

(Poulin[65]).

[Footnote 65: _Étude sur les Atrophies viscérales consécutives aux

Inflammations chroniques du Sereuses, etc._, Thèse de Paris, 1880.]

PATHOLOGICAL ANATOMY.--Several forms of cirrhosis are recognized by the

modern French school of pathologists. According to Sabourin,[66] there

is an annular, a monolobular, and a multilobular form. These differ

merely in regard to the arrangement of the new connective tissue. At

the outset of the disease the liver is increased in size and hyperæmic.

Its consistence is also greater than normal. The outer surface is at

this period smooth, but on section the islets of the parenchymatous

tissue, yellowish in color, are distinctly visible between the grayish

or pale-rose tint of the intervening or proliferating tissue. This

reddish-gray material consists of fine connective-tissue elements

containing spindle-shaped cells.[67] The development of this material

is such as to even exceed in quantity the proper glandular structure.

The bands of newly-formed connective tissue extend between individual

lobules (monolobular cirrhosis) or between groups of lobules

(multilobular cirrhosis). A portion of the spindle-shaped cells form

new vessels communicating with the branches of the hepatic artery.[68]

Coincidently with the formation of the new connective tissue ensues its

contraction. The enlarged organ diminishes in size from a slight degree

to one-half its original volume; especially in the left lobe is the

diminution of size most marked. On the surface it exhibits a knobbed or

nodular aspect (hobnail liver), and these knobs present through the

capsule a yellow appearance. The granulations, so called, consist of

small prominences corresponding to lobules or groups of lobules, and

hence vary in size from that of a pinhead to that of a pea.[69] Between

these are the sharply-defined masses of connective tissue. On section

the organ is found to be of firm almost cartilaginous hardness, and

between the interlacing bundles of connective tissue are the small

islands of parenchymatous tissue projecting above the cut surface and

having a yellowish or brownish-yellow color. As the terminal branches

of the portal are compressed in the process of shrinking undergone by

the new connective tissue, they are destroyed. The result of this

obliteration of the portal radicles is the impaired nutrition of the

lobules and atrophy of the cells. Formerly it was held that the atrophy

of the hepatic cells was due to the compression exercised by the

contracting connective tissue, and Beale[70] even maintained that the

change began in {993} the cells, the connective tissue contracting as

the cells receded before them. This view has been reaffirmed by

Ackermann in a paper read last year before the Congress of German

Naturalists and Physicians, but without any acknowledgment, so far as I

can ascertain, of Beale's long-before expressed opinions. In the

discussion which followed the reading of Ackermann's paper the position

of its author was supported by Aufrecht, Küssner, and others, but

controverted by Rindfleisch. It has been demonstrated by Cohnheim and

Litten[71] that the lobule is nourished not only by the portal

radicles, but by the branches of the hepatic artery, which enter, by

the interlobular vein, the capillaries of the lobule, and hence the

nutrition of the cells suffers in consequence of the lessened

blood-supply; but it is probable also that more or less compression is

exercised. When the cells are destroyed, their remains may be discerned

in the mass of connective tissue as fine fat-granules or masses of

pigment yellowish or brownish in color. The peculiar appearance to

which the name cirrhosis is applied is due to the lobules or groups of

lobules which project on section above the divided surface, and are

colored yellowish by the bile-pigment, which here exists in an

exaggerated quantity. The cells themselves are not normal: they are

enlarged by compensatory hypertrophy, and they contain much

bile-pigment and a considerable quantity of fat. The compression of the

capillaries, especially their obliteration, leads to stasis of the

blood and its consequences in the whole chylopoietic system.

SYMPTOMS.--The development of sclerosis is usually very insidious.

After some years' indulgence in spirit-drinking or affected for a

length of time with the other causes of the malady, a gradual decline

of vigor occurs. The complexion takes on a fawn color, stigmata slowly

form on the face, there is more or less yellowness of the conjunctiva,

and attacks of headache, giddiness, and even severe vertigo, are

experienced. An increasing indisposition to mental effort, some

hebetude of mind, and a gradually deepening despondency are felt. The

appetite gradually fails, becomes capricious, and only highly-seasoned,

rather odd, or unusual articles of food can be taken. Such subjects

acquire a taste for condiments, for such uncooked vegetables as onions,

celery, raw cabbage, etc., for fruits, and get a distaste for

plainly-cooked meats and vegetables, for sweets, etc. The digestion is

as capricious as the appetite: at first there are times of appetite,

again of indifference, then of disgust; some heaviness is felt after

meals; gaseous eructations, acidity, pyrosis, nausea, occur day after

day as the case advances; and ultimately morning vomiting is regularly

experienced. Nausea is felt on rising; then with much straining and

distress a little glairy mucus and a teaspoonful of bile are brought

up; after which, it may be, a little food can be taken. It is only

after the case is fully declared that these troubles of stomach

digestion become constant; previously they occur now and then in a

paroxysmal way, whilst between there is only labored digestion.

As the compression of the portal radicles maintains, by reason of the

obstruction, a constant hyperæmia of the intestinal mucous membrane, a

catarrhal state, with fermentation of the fatty, starchy, and

saccharine constituents of the food, and hence complicated products of

an irritating kind, must result therefrom. Hemorrhoids, varying in size

according to {994} the degree of obstruction, form, sometimes bleeding

more or less profusely, again being merely troublesome or painful.

Fissures of the anus and fistula in ano not unfrequently complicate the

case. The bowels are necessarily rather relaxed than confined, but at

the onset of the malady they may be confined, afterward assuming more

or less of the characteristics of diarrhoea. The stools may be

offensive with the products of decomposition, rather clay-colored or

golden, or brownish and almost black from the presence of blood. In

some cases the stools are parti-colored--clay-colored in part, brownish

in part--and in exceptional examples continue normal or nearly so until

near the end. As the transudations from the portal vessels increase,

the mucous membrane of the intestinal canal becomes oedematous, and,

the normal secretions being arrested, the discharges finally consist of

a watery fluid, whitish or grayish, dark-brown or blackish, and very

offensive. The decomposition of foods instead of their proper digestion

and solution, and especially the fermentation of the starchy and

saccharine constituents of the aliment taken, produce a great quantity

of gas; hence meteorism comes to be an ordinary symptom. The

accumulation of gas is greatly promoted by the paretic state of the

muscular layer and by the relaxation of the abdominal walls consequent

on the oedema of the muscular tissue. A high degree of distress is

sometimes caused by the great accumulation of flatus; the abdomen is

greatly distended and the diaphragm is pushed up against the heart and

lungs, compelling the patient at length to sit up to breathe with ease.

Of course the accumulation of fluid may be greater, and the gas only

add to the discomfort.

A very common symptom is hemorrhage. Sometimes it happens, indeed, that

this is the only evidence of the portal obstruction at first observed.

Hæmatemesis is more common than intestinal hemorrhage. Now the blood

may be large in quantity, appear little changed from its usual

coagulated state, and be brought up promptly with slight effort of

vomiting; now it is passed by stool, is in coffee-colored, granular

masses or in a tar-like, semifluid state; and again it appears in

coffee-grounds mixed with the contents of the stomach. These variations

are due to the character, seat, and extent of the hemorrhage and to the

condition of the mucous membrane. Merely-distended capillaries,

yielding, may furnish a little blood, which, acted on by the gastric

juice, forms coffee-grounds, or, if not acted on in consequence of the

failure of the gastric glands to functionate, appears as bloody streaks

mixed with mucus. Enlarged veins, giving way, may furnish a large

quantity of partly-coagulated venous blood, charred or not as the state

of the juices will determine. In some cases hemorrhages into the

submucous tissue or thromboses of the submucous veins lead to solution

of the membrane thus deprived of its nutritional supply, and ulcers

form. Two admirable examples of this kind have been seen by the writer

in which large hæmatemesis occurred from ulcers near the pylorus. They

were round, smooth ulcers, containing coagula, and the eroded vessels

(veins) were readily seen opening into the cavity of each.

The obstruction to the portal circulation results also in an

enlargement of the spleen. There may be a simple enlargement due to the

hyperæmia merely; there may be an enlargement due to the hyperæmia and

to a resulting hyperplasia of the connective tissue; there may be also,

in {995} addition to the second form of enlargement, amyloid

degeneration, syphilitic hyperplasia, etc. The increased dimensions of

the spleen are by no means always made out, and authorities differ

greatly as to the proportion of cases in which the enlargement can be

detected. The organ may indeed be considerably enlarged whilst pushed

upward into the left hypochondrium by the effusion, and yet the attempt

to measure and define its dimensions may be fruitless. From a slight

increase due to the hyperæmia up to the enormous dimensions acquired by

the added amyloid material there are all possible variations in size.

Partly in consequence of the increased blood-pressure in the vessels of

the peritoneum, and partly in consequence of the watery condition of

the blood itself, effusion takes place into the sac of the peritoneum.

Such an accumulation is known as ascites, or dropsy of the abdomen. The

time at which the effusion begins, the amount of it, and the degree of

contraction of the liver necessary to produce it, vary in each case.

Ascites may be the first symptom to announce the onset of cirrhosis; it

is more frequently amongst the later symptoms, and is the evidence of

much interference in the portal circulation. However, it is not due

wholly to hepatic disease. The blood in cirrhosis is much reduced and

watery, hence slight causes suffice to induce an outward diffusion.

Given a certain obstacle to the passage of the blood through the liver,

transudation will be the more prompt to appear the greater the anæmia.

In some cases an enormous quantity of fluid collects: from ten to

thirty pounds may be regarded as usual, and forty to sixty pounds as

exceptional, although the highest amount just given is not rare. The

fluid of ascites nearly represents the serum of the blood. It has a

straw color and is clear, but it may have a reddish tint from the

presence of blood, a greenish-yellow or brown from bile-pigment. The

solids of the serum are in the proportion of from 1 to 3 per cent., and

consist of albumen chiefly and salts, of which sodium chloride is the

principal. Hoppe's[72] analysis gives this result: 1.55 to 1.75 solids,

of which 0.62 to 0.77 is albumen. According to Frerichs, the amounts of

solids ranges from 2.04 to 2.48, and of these albumen constitutes 1.01

to 1.34.

[Footnote 72: _Virchow's Archiv für path. Anat., etc._, Band ix.]

Oedema of the inferior extremities comes on after, usually--rarely

with--the ascites. If the mechanism of this oedematous swelling be as

supposed, the effusion into the areolar tissue necessarily succeeds to

the abdominal effusion. The pressure of the fluid in the cavity on the

ascending vena cava and iliac veins seems to be the principal factor;

but to this must also be added the intestinal gas, which in some

instances exerts a powerful force. The ankles have in rather rare cases

appeared swollen before the abdomen, but the detection of fluid in the

peritoneal cavity when in small quantity is not always easy. Obese

women, with much accumulation of fat in the omentum and flatus in the

intestines, have swollen feet and legs if erect for some time, the

effusion being due to pressure on the vena cava. The legs may become

enormously distended. The scrotum and penis in the male, the vulva in

the female, the buttocks and the abdominal wall, also become

oedematous, sometimes immensely. Walking grows increasingly difficult.

Warmth and moisture and the friction of the sensitive surfaces excite

vesicular and pustular eruptions where the {996} scrotum and labiæ come

in contact with the thighs. Urination may be impeded by the oedema of

the prepuce.

An attempt at compensation for these evils growing out of the

obstruction in the portal system is made by the natural powers.

Anastomoses of veins through minute branches are made use of to convey

the blood of the obstructed portal circulation into the general venous

system, and to this end become greatly enlarged. The interlobular veins

being obliterated by the contracting connective tissue, the pressure in

the branches and trunk of the portal vein is much increased. Hence an

outlet is sought for in the veins which communicate between the portal

and the ascending vena cava. One of the most important of these is a

vein in the round ligament, at one time supposed to be the closed

umbilical vein, but proved by Sappey to be an accessory portal vein.

Bamberger,[73] however, has found the umbilical vein pervious, and

since, Hoffmann[74] has demonstrated the same fact. It is probable,

indeed, that Sappey's observation is correct for some cases. In either

event, the veins of the abdominal wall about the umbilicus

communicating with the epigastric become enormously distended, and in

some advanced cases of cirrhosis form a circle known as the caput

Medusæ. Further communication between the portal and the veins of the

diaphragm takes place by means of the veins in the coronary and

suspensory ligaments. In some instances a new route is established

between the veins of the diaphragm and the portal by means of new

vessels formed in the organized connective tissue resulting from

perihepatitis. Still another channel of communication exists between

the inferior oesophageal veins, the azygos, and the coronary, and

finally between the inferior hemorrhoidal and the hypogastric. The more

completely can communication be established between these anastomosing

veins the less severe the results of portal obstruction.

[Footnote 73: _Krankheiten des Chylopoiet. Syst._, _loc. cit._]

[Footnote 74: Quoted by Thierfelder, _op. cit._]

Besides these indirect evidences of portal obstruction and a

contracting organ, there are direct means of ascertaining the condition

of the liver. By the methods of physical diagnosis we may acquire much

information. On auscultation, as our Jackson[75] was the first to show,

a grating or creaking like leather, or friction sound, is audible over

the right hypochondrium synchronously with the respiratory movements or

when produced by moving with the fingers the abdominal wall on the

liver. This sound is caused by the bands of false membrane which extend

between the two surfaces, and hence indicates a secondary

perihepatitis.

[Footnote 75: _The American Journal of the Medical Sciences_, July,

1850.]

To ascertain the dimensions of the liver--to mark out the area of

hepatic dulness--with accuracy is a most necessary procedure. The

period of the disease is an important element in the problem. When the

new material is deposited and the congestion of the portal system first

occurs, an increase in the dimensions of the organ is observed. This

enlargement, of brief duration, must not be confounded with the

hypertrophic sclerosis, another form of the malady. So considerable is

the increase in the size of the liver that there is an evident

enlargement of the right hypochondrium, and the whole abdomen seems

fuller. The organ may be felt, on palpation, projecting one, two, or

even three fingers' breadths below the margin of the ribs, and the left

lobe extends well across the epigastrium, increasing the sense of

resistance and the area {997} of dulness in this direction. The

enlarged liver, as felt below the ribs, appears firmer than is natural,

is yet smooth, and the margin is sharply defined. The duration of this

period of enlargement is indefinite, but it is rather brief, and is

followed by the contracting and atrophic stage. It is not often,

indeed, that the patient presents himself during the period of

enlargement. Sometimes a perihepatitis or an unwonted tenderness in the

right side compels attention during this stage, but more frequently it

escapes notice. If perihepatitis occur, there will be fever, pain, and

tenderness, a slight icterode hue of the skin, and possibly

Jackson's[76] friction sound. These symptoms, taken in conjunction with

the history of the case and the obvious enlargement of the organ, will

indicate the existence of the first stage of sclerosis.
