This name, derived from the Greek (XoXrj, bile, and hZos, a stone), is used to designate that state of the system in which biliary calculi are formed. This disease, without being one of the most frequent, is yet far from rare. A good deal of practical knowledge concerning it has already been accumulated, yet we must admit much remains to be ac- quired, and much is still shrouded in obscurity. The following paper is based upon the study of thirty-five cases observed and treated by me, and is offered as embodying the results of my studies and clinical experience with a disease which for years has been of deep interest to me. It has been suggested by several distinguished observers that the formation of gallstones depends upon a peculiar diathesis. In support of this view they allege that in many of these patients there is an evi- dent predisposition manifested by a constant formation of gallstones, and this in spite of all treatment; that the disease is often hereditary; that there is a certain close connection between the state of the system that induces the formation of gallstones and which results in the for- mation of urinary calculi; and, finally, that this constitutional state is gout. I have not been able to corroborate this view; on the contrary, I have been compelled 'to regard this disease as due to local or general causes entirely independent of any diathesis whatever. Some cases are rebellious, and obstinately resist all our efforts to cure; but when one reflects how difficult it is to continuously and completely control these patients, and when the various features of the disease are taken into account, this rebelliousness to treatment is more readily explained by the persistence of local causes without assuming the existence of a peculiar constitutional vice. In only two of my cases were any of their ancestors known to have A Paper on Chole-lithiasis. 4 had gallstones, and I therefore conclude that heredity plays but a feeble part in their production. Morgagni thought that hepatic colic in a patient subject to urinary calculi gave strong reason for suspecting the existence of biliary calculi, especially if the patient be an adult. Subsequent writers have noted the co-existence of these two forms of lithiasis, and have expressed a belief in their mutual connection. I am led to believe it is quite rare and incidental, for it was not observed in a single one of my thirty-five cases. Neither did I ever find any of the usual manifestations of gout in the persons I have treated for gall- stone. Gout is notoriously uncommon in women, but it is especially in them that gallstones are most often found. Causation. The etiology of gallstones is one of the “dark points” upon which much additional light must be shed before our knowledge concerning them can be satisfactory and complete. Age is one of the general conditions operating at least as a predis- posing cause. Gallstones are most common after middle-age. My oldest case was in a woman seventy-six years old; my youngest was another woman aged twenty-two. They have, however, been found in children ten and two years old, and even in new-born infants. These very young subjects did not, so far as I can learn, suffer from hepatic colic, and the presence of the concretion was only recognized after death. I do not know what is the earliest recorded age at which they have begun their travels and thereby occasioned trouble. Sex.—The greater susceptibility of women than men to this disease is well known. It is said to be in the proportion of three of the former to two of the latter. In my cases the difference was even more marked, being twenty-nine women to six men. Habit and Regimen. The majority of persons suffering from chole-lithiasis are large eaters> and fats enter prominently into their dietary. Jaccoud insists that they are generally corpulent. A tendency to obesity was noticed by me in thirty out of thirty-five.

It also pro- motes deposition of biliary constituents in the gall-bladder, which is strongly favored by too prolonged intervals between meals, and indeed by any retardation of the flow of the bile. Precipitation of the solid constituents of the bile may be determined by a variety of local con- ditions, which I will mention in detail. The general conditions just set forth act at most as a predisposing cause, which, without the action of a local cause, would be wholly inoperative so far as the development of gallstones is concerned. Diet undoubtedly has a certain influence in the production of gall- stones, both in man and in some of the lower animals. It has been observed that biliary calculi are more frequent in the gall-bladder of stall-fed oxen and sheep who have been fed on dry hay than in those who have been at pasture. I have inquired as to the occurrence of gallstones in horses with the hope of throwing additional light on the general etiology of this disease, but was sur- prised to learn that among them it is so rare that only one case has been recorded. Percival* believes this immunity is due to the sim- plicity of the biliary apparatus in these animals. Local Causes. 1. Increase in the solids of the bile to such amount that the physi- ological solvent can no longer hold them in solution, the excess being thrown down and forming biliary calculi. This mode of formation is beyond the reach of demonstration, but one can readily conceive it to be possible, and certain facts render it quite probable. Gallstones become frequent at the age when the bile contains a larger amount of cholesterin, and Chevreul has shown that in several persons with chole- lithiasis the bile was excessively charged with fats.f 2. A diminution in the amount of biliary solvents, cholate and choleate of soda and potassa, causing a precipitation of solids normally held in solution. This mode of formation is still less capable of dem- onstration than the former, but it is rendered probable by the effects that have been observed on administration of biliary salts in certain cases of chole-lithiasis. *0n the Diseases of the Digestive Organs of the Horse.

Dr. Thudicum* notes that in some cases the unclear part is com- posed of casts of the bile-ducts, and the central part often consists of small concretions of bile pigment which have fallen from the smaller ducts. A clot of blood, a globule of mercury, a fruit-stone, have been found as nuclei of gallstones. In one case the nucleus was composed of a lumbricoid worm, in another it was a pin. This is doubtless a rare mode of formation, but it does occur, which shows that when once a nucleus exists biliary matters tend to become deposited around it. 4. Catarrhal inflammation of the biliary passages. This is the most efficient and probably the most frequent cause of gallstones. In health all the constituents of the bile are held in solu- tion, probably by the cholate of soda. But when catarrhal inflammation of the mucous membrane of the gall-bladder sets in, its solvent power is lost, the bile is decomposed, and its solids are thrown down either in the form of a pulverulent mass or larger particles, which tend to increase by continued accretion.^ Drs. Thudicum and Gomp. Bezanez have shown that when bile is allowed to stand for a long time in a bottle, acid decomposition takes place spontaneously and pigment hitherto dissolved is deposited. That the influence of catarrhal mucus in the gall-bladder plays an import- ant part in the decomposition and precipitation of bile, and the subse- quent formation of calculi is rendered still more probable by analogous changes in the urinary bladder, owing to cystitis, so familiar to all that more extended mention is superfluous. 5. Another suggestion made by Thudicum is that decomposition of bile may also be due to a putrid ferment absorbed by the intestine; but of this I have seen no proof, nor of its agency in the production of gallstones. Catarrh affecting the biliary passages within the liver may, though rarely, produce a similar result as when affecting the gall-bladder. Structure. The usual seat of gallstones is in the gall-bladder. They are less commonly found in the cystic, hepatic, and common choledoch duct, *Thudicum on Gallstones, page 166. f Jaccoud loc. cit. A Paper on Chole-lithiasis. 7 and it is only seldom that they are found occupying the biliary canals within the liver. In this latter locality they are invariably quite small. Their volume varies from the small size of sandy particles to that of a hen’s egg, and even larger,* and is in inverse ratio to their number. When there is only a single calculus present it may fill the whole gall-bladder, and usually corresponds in outline to the form of the latter. The surface of the concretion may be rough or smooth, but the walls of its receptacle generally fit it closely, sometimes sending down processes of mucous membrane into the depressions which here and there furrow its surface. Multiple calculi, by reciprocal attrition and pressure, assume facet shapes and convex and concave surfaces, and thus come to fit perfectly together. Sometimes they present the form of regular tetra- or octa-hedral crystals. In consistence they may be firm or waxy, but are most often brittle, break readily between the fingers, and soon crumble either spontane- ously or on slight pressure. I have, however, in my collection, gallstones passed twelve and thirteen years ago, and which are still perfectly hard and intact. The material holding the particles together is thought to be cholic or choloidic acid, or both; it has also been supposed to be mucus. The color is subject to infinite variation; they may be whitish, brownish yellow, brown, green, blackish, mottled, or streaked. They are made up of many strata of different materials, and the differences in color between these various layers are often very great. The calculi have a nucleus, sometimes multiple, chiefly composed of biliary pigment in combination with lime, traces of mucus, and earthy phosphates. Around this nucleus the materials that constitute the concretion become deposited in regular or uneven strata. A ma- jority of the calculi are composed entirely of cholesterin, with a nucleus of calcareous matter, or pigment. Now and then this pig- ment is more abundant, and is sometimes uniformly distributed through- out the mass; at other times it and cholesterin form alternating layers. In some cases there is no cholesterin at all, and the calculi consist exclusively of carbonate and phosphate of lime. Uric acid\ has been found in them, and they generally contain traces of iron, manganese, and copper. * See an interesting case, with illustration, recorded in the American Practitioner February, 1877. -j- Stockhard and Marchand. 8 A Paper ou Chole-lithiasis. The specific gravity is light, and varies with the composition; when chiefly of cholesterin they float in water. Ordinarily they are slightly heavier than this liquid, and sink in it. There may be fullness of the gall-bladder, and when palpation is practiced the calculi are felt as hard, movable bodies, producing by contact with each other, a crackling sound, which may be heard with the stethoscope, and is said to resemble the noise made by tapping upon a bag containing nuts or dry beans.* A large calculus can be accurately made out, as shown by Buckler and others. Biliary calculi being once formed may remain quiescent within the gall-bladder for an indefinite length of time. I have never seen a case where the diagnosis could be made under such circumstances, though it is sometimes practicable.f In certain cases, however, they do not remain latent, but give rise to disturb- ances of different kinds. i. The calculi excite irritation within the gall-bladder. Ordinarily they may exist even in large numbers without giving rise to changes in the mucous membrane; at other times they are merely the lesions pecu- liar to a catarrhal inflammation.f But in a smaller proportion of cases their presence induces suppurative inflammation, which may terminate in perforation, sometimes into the peritoneum, the stomach, the bowel portal vein, ureter, or into the pleura. But fortunately it is usually pre- ceded by the formation of adhesions to neighboring organs. This is especially likely where the opening takes place externally. Such a case came under my observation many years ago through the kindness of the late Dr. Lewis Rogers, who was so justly distinguished in life and so deeply mourned in death. The patient, a woman of middle-age, had for a long time suffered from dull, recurrent pains in the region of the gall-bladder. After a while she had sharp, shooting, and then throb- bing pains and fever. A swelling appeared, and an abscess formed, which broke e’xternally, and several gallstones were discharged through the wound. In time the opening closed and the patient recovered. Chronic inflammation may also be developed when the walls of the gall-bladder thicken and contract and the liquid contents become condensed by absorption of the water, and the gallstones become * Petit. fjaccoud Path.

The gallstones are disturbed and travel along the ducts, giving rise in their migrations to the symptoms of hepatic or gallstone colic. I have often found biliary calculi at the post mortem examinations of persons in whom their presence had never been suspected during life, and many persons pass small gallstones without any pain, especially at Carlsbad and Marienbad while drinking of these justly celebrated mineral waters; yet ordinarily the passage of one of these concretions is attended by characteristic and severe symptoms. Symptoms and Course. Calculi within the liver itself are even more likely to remain latent than when they quietly occupy the gall-bladder, but their symptoms are so extremely obscure that a diagnosis can scarcely be based upon them. Ill defined paroxysmal pains, not radiating, but confined to the right hypochondriac region, absence of jaundice, and hepatic enlargements, with, perhaps, slight digestive derangements, constitute their whole number. When an intra-hepatic calculus in its downward course becomes lodged in the hepatic duct there is fixed pain, persistent jaun- dice, with whitish evacuations, and the liver becomes speedily enlarged, but the gall-bladder is not distended, and this is a symptom of diag- nostic importance in differentiating between obstruction of the chole- doch duct and of the hepatic duct. It has already been mentioned that calculi may remain for a long time in the gall-bladder without giving rise to irritation, but in certain cases their presence induces chole-cystitis, sometimes so slight and superficial as to be unattended by any symptoms, while at other times involving the whole thickness of the wall of the gall-bladder and sig- nalized by acute symptoms of great severity. There are then severe pains in the region of the gall-bladder, con- stant, but with paroxysmal exacerbations, during which they radiate to the epigastrium, loins, and right shoulder, and also fever. The neck of the gall-bladder is of necessity implicated in the inflammatory process, and becomes obstructed; hence, to the symp- toms above related is added distension of the gall-bladder, which gives rise to a pyriform tumor in this region. But there is no jaundice, which A Paper on Chole-lithiasis. 10 is a point of importance as establishing the diagnosis between this con- dition and obstruction of the choledoch duct. Chole-cystitis ordinarily terminates in recovery, but may result in perforation and peritonitis, as already mentioned, with the alarming and grave symptoms that accompany that event. An interesting case of chole-cystitis from gallstones is reported by M. Paulet in Allg. Wiener Med. Zeitung, 1875, as follows: A woman aged 42, mother of eight children, began in November, 1874, to feel a severe pain in the right side. On examination there was found a somewhat diffuse tumor about the size of a child’s head, which extended from the umbilicus to the anterior superior spinous process of the ileum. As the case was attended by fever it was diagnosticated as one of suppurative ovaritis. In December it was determined to open the tumor with Vienna paste. In three days the skin was destroyed, and in seven the aponeurosis. An exploratory incision was now made, from which a little fluid escaped, but the needle came in contact with numerous hard bodies, which on removal proved to be gallstones. Forty of these were then taken out and a large one found almost encapsulated. It was broken, divided, and extracted without much difficulty, and some bile was also dis- charged. This biliary fistula soon closed, and in March, 1875, the patient had entirely recovered. It is difficult to understand why in some persons gallstones, even in large numbers, should remain in the gall-bladder without indicating their presence by any symptoms, and why in other cases they should be so often disturbed from their resting-place and urged along the various passages until finally ejected from the system. Speculation on this point is vain. There seems to be some connection between the inception of an attack of biliary colic and the period of greatest functional activity of the small intestine and neighboring parts consequent upon a full meal. The paroxysm ordinarily begins two or three hours after a meal, and patients are prone to believe that food has disagreed.

It has already been remarked that biliary sand and concretions of larger size may pass without un- pleasant symptoms, and even without the knowledge of the patient, but such is not the general rule. I have noted the symptoms of at least 150 attacks of gallstone colic, and though they were subject to great variation as to severity and dura- tion they were also characterized by great uniformity, so far as their number and character were concerned. (a) The earliest symptom is usually either shivering or a sense of discomfort and distress in the epigastrium. This is soon followed by (£>) nausea, vomiting, and (
