BY ALVIN EVER, M.D., CLEVELAND, O. Reprinted from the Medical Record, August i, 1891. December 17th last, Charles G. S was admitted into Lakeside Hospital with the following history: Rail- way brakeman, aged twenty-eight, with good general health up to the previous day, when he met with an ac- cident, the following report of which is as complete as could be obtained. By the slipping of a " push pole " (a pole attached by one end to an engine and used in mov- ing cars) he was so caught as to be squeezed against the foremost car and bodily rolled out from between the two. When picked up he was found several feet from the train and in an unconscious state. Upon being brought some thirty miles an examination brought to light little beyond severe localized pain in the right lower chest with some considerable injury to the right forearm, and a distinct band of discoloration some four inches in width, encircling nearly the entire abdo- men. While no crepitus was found it was still thought 2 best to firmly strap the right chest as a precautionary measure against possible fracture of one or more ribs. This, with attention to the injured arm and such anodyne treatment as was required, was all that was deemed nec- essary for the time being. In the course of twenty-four hours, however, there was a rise of temperature and upon auscultation evidences of pneumonia, corresponding to point of injury over right lung, were plain. He was at once placed upon additional treatment, and for the next sixteen days seemed to run a favorable, yet perhaps se- vere, course of traumatic pneumonia involving the entire lung. Beyond somewhat more pain than one generally ob- serves in such cases, however, nothing unusual presented itself, except on the second day, when there appeared a gaseous distention of the abdomen and also enough dys- pnoea with a hyper-resonance of both lungs to suggest pneumothorax; but whether pneumothorax actually ex- isted or whether this condition depended upon the ab- dominal distention was not definitely determined at once and in twenty-four or thirty-six hours the whole chain of symptoms, in so far as the thorax was concerned, passed away, leaving the patient about as before with the excep- tion of more or less constant abdominal tympany. On the seventeenth day there came a great and most remarkable change over our case. Pain was complained of, and upon examination some redness with soreness upon pressure was found directly above and somewhat behind the anterior superior spinous process of the right ilium. Upon deep pressure fluctuation could be ob- tained ; and after the introduction of an exploring needle, an opening was carefully made quite down upon the ex- ternal oblique muscle. The moment the fistulous tract was struck there came a gush of most offensive gas, followed by a flow of nasty- smelling discharge, not unlike fecal matter both in ap- pearance and odor. So offensive was this discharge that the patient had to be removed from the general ward into 3 an apartment by himself. An intestinal fistula was at once thought of, and in the next day or two, with the opening still discharging a fluid very similar in appear- ance to what was given him to eat (expressed beef-juice, milk, and whiskey), and with repeated assurances of the orderlies that its odor was identical with what had passed per rectum, the diagnosis of such a fistula confirmed itself in our minds without further or special investigation. After two or three more days the discharge lost its offensiveness to a very great degree; but otherwise re- mained much the same-opaque and milky-with marked increase of flow at any time the patient was asked to bear down as though at stool. At this time, too, rapid ema- ciation set in, and from these two facts-loss of odor and the unusually rapid emaciation-it was inferred that the intestinal lesion was high up and the food-stuffs given him came away as chyme. Under this belief it was deemed best to limit stomachic alimentation, as to quan- tity, and confine it entirely to predigested nitrogenous foods, while rectal feeding was pushed to its utmost limit Notwithstanding, however, this forced feeding and the apparent well-doing of his pneumonia the patient was still rapidly succumbing to starvation. So rapid was his inanition that it was estimated his body loss-from the date of fistulous formation (seventeenth day) to death (thirty-eighth day)-exceeded four pounds per diem, and that his entire loss much exceeded one half his normal body weight. During all this time we could see nothing to be done, more than sustain strength and life until such time as the patient's pneumonic condition would permit a restora- tion of the intestinal continuity, keep the tissues of the right side well open to favor drainage, and prevent sloughs. Starvation, however, went uninterruptedly on, and as already stated, death supervened on the thirty- eighth day after injury. This, then, briefly stated, covers the history, clinical course, diagnosis, and fatal ending of our case. To sum 4 up its clinical significance we wiil take up : First, our diagnosis, not in its entirety, but only in so far as the fis- tula was concerned ; second, the autopsy and its findings; third, a study of the case, upon the whole, with the view of establishing a differentiation between fistulas com- municating with the thoracic duct, and such other fistulous tracts as may prove undefined or doubtful as to origin. i. In defence of our diagnosis of intestinal fistula I will only say : In the sixteen days' observation of the case there were, with but three exceptions, absolutely no indications of disease or injury other than those refer- rible to the right lung-now in an advanced stage of pneu- monia. With the appearance, therefore, of the painful bulging, followed by the rush of gas and fluid upon lancing, which plainly established the existence of some form of fistula, the exceptions-a band of discoloration, obstinate bowels, and slight tympany-were recalled ; and, for the life of me, nothing could have been plainer or more easy to diagnose. In fact, the whole case seemed too plain and simple to be mistaken. The gas and decidedly fecal smelling dis- charge in themselves moulded at once our belief, diag- nosis, and mistake. That there was a fistula was plain; that it was fecal was too plain, and there we rested. To give you the benefit that was given the House Staff, let me tell you, as was told them, how all this chain of occurrences happened : "You see this man was caught between the end of a pole and a box car; the little black and blue band about his waist plainly indicates to you what part of the body was caught. Now the pole must have so squeezed the abdominal parieties up against the car, as to impinge a knuckle of gut within its embrace; and while this did no immediate or serious injury to the belly or its contents, there still must have been enough harm done to subse- quently set up a low form of plastic inflammation where- 5 by the gut and peritoneum became agglutinated and ad- herent one to the other. " In due time, of course, death took place in that por- tion of the gut and the delicate serous membrane which was most centrally located in the adhesion, and then the tissues gave way and the fistula became established. Of course it could not communicate with the abdominal cav- ity, because you see the opening through the gut and peritoneum was simultaneous; and as the healthy por- tions of the two are still adherent there is a sort of artifi- cial anus formed, and through it, of course, the fecal matter must pass, then force its way on through the extra-peritoneal tissues in whatever direction it finds least resistance. Observe as you make pressure on this side a wave appears on the opposite side, not far under- neath the skin, and beginning evidently in the linea alba. That is the fluid coursing its way through the newly made channel toward its outlet. " As to what can be done in such cases, for the pres- ent we will only make a freer opening, so as to give free vent and prevent the burrowing of fluids and subsequent sloughing. Later on, of course, when his pneumonia has subsided, laparotomy with, perhaps, enterectomy, will be performed, all of which will be a simple matter. " Stimulate and feed him well, for, as you see from what has been said concerning the character of the dis- charge, which really seems to be nothing more than par- tially digested milk, whiskey, and beef-juice, the lesion must be high up, and therefore the area for absorption is greatly cut off. " The discharge which, you will remember, was so very offensive no longer smells badly, which also means that the foods leave the canal high up, and therefore have no chance for decomposition. " This without doubt would be a nice case for Senn's hydrogen gas test, but, as the case is so plain and the poor fellow has already been badly hurt, we will pass that by. The pneumonia, of course, is a contra-indication for 6 the use of an anaesthetic, so all we have done, as you know, had to be done under the local spray and cocaine, neither of which is very effectual." These, in substance, were the clinical points upon which was based our diagnosis two days after the fistulous formation. From then on the patient's pneumonia did well and seemed promising; and so was also our forced feeding borne well by him, but he starved to death on the thirty-eighth day, and thus ended our first lesson. Autopsy.-In making the autopsy it was at first deter- mined to follow the tract from without in, but as it proved to run an unfavorable course for such a step, the attempt was abandoned and the abdomen gone into through the linea alba-the incision extending from the ensiform cartilage to the.pubes. At first glance there could be seen many evidences of starvation's fearful rav- ages. All the viscera presented an unusual dryness, with the surface of the intestines and liver much darker in ap- pearance than normal. The gall-bladder was greatly dis- tended and seemed on the point of bursting; while the omentum, always so rich in fat, was but a mere network of blood-vessels and connective tissue. These points being noted the point of " adhesion " was at once looked for, but no such condition could be found; and then a search for the fistula began. For this we looked high and low. Applying a double ligature just above the sigmoid flexure and dividing the gut between the two, we emptied the abdomen from below up, carefully noting every patho- logical change as we went. Up to the diaphragm we failed to find even evidences of inflammation, new or old. In fact, the abdominal cavity seemed absolutely free from pathological condi- tions, and after going over the intestinal tract again and again, we thought it possible that the oesophagus might be the seat of lesion. So accordingly the liver and pancreas were removed and the diaphragm, beginning at the oeso- phageal opening, slit up to the ensiform cartilage. In removing the liver from its lodgment it was observed 7 that it was adherent to, and much softened about the aortic opening in the diaphragm, with evidences of recent in- flammation, and several masses of a cheesy deposit, not unlike the residue of partially digested milkin appearance, embedded in its upper surface. The diaphragm up to the oesophageal opening also showed the same evidences of inflammation, and at this latter point the bands of muscle forming the opening were so adherent and matted to the gullet that, in separating and lifting the latter out through the cut made in the diaphragm, it was so torn as to prevent us from determining whether its destruction had been ante-mortem or made by us. From the character, however, of the blackened and broken-down tissues, not only of the liver blit the diaphragm and oesophagus, and our failure to find any other lesion, we momentarily concluded we had reached the seat of trouble. The sternum and cartilages were next removed and after carefully examining the diseased right lung, which was found in various stages of hepatization, the same was lifted out of the thorax, and the upper surface of the diaphragm about its openings further examined. Its con- dition was similar to that found below, except, perhaps, that the inflammatory process had not been so extensive. The gullet above this point was also further examined but found to be perfectly healthy. Upon complete removal of the lung from the chest there was discovered a bulging into the cavity, from the back and uppermost point of its apex, which upon more careful investigation was found to be a post-pleural collection of fluid. Upon tapping its sac this fluid seemed to be identical with that which had been making its escape per fistula during life, and further examination proved this finding to be correct. The pent-up fluid was our supposed chyme, and had bur- rowed its way between the pleura costalis and chest-wall by gravity while the patient was flat upon his back. A careful dissection also proved the incorrectness of our just- formed belief that the lesion could have been in the oesoph- agus at the point of opening in the diaphragm, for in 8 no way could that tear and the newly found cavity be made to connect. This discovery, then, put us entirely at sea, and it was not until the bulging pleura was again referred to and its contents found to consist of a rich creamy clot, overrun by a brownish liquid, that a chyle- clot and lymph were thought of. Specimens were at once examined by heat and the microscope. The former clearly proved the fluid to be pure lymph, while the microscope showed us a collection of the most beautiful specimens of chyle-corpuscles ever looked upon. Thereupon the autopsy was brought to a speedy end by going directly into the posterior medias- tinum, and but little deeper than we had gone for the gullet, where the hard-looked-for hole was found-not in the alimentary canal, however, but in the thoracic duct. It was through this hole, then, that all our endeavors for the poor fellow's life had slipped. The fistula was found within the very opening formed by the diaphragm for the tube's reception, and the diaphragmatic crura, fasciculi, and interdigitations surrounding it likely had much to do with its formation, and probably led to the division of the stream of chyle, directing the one into the thorax and the other through the muscles of the back and abdomen to its ultimate point of outlet. Points of Differentiation, as presented in this case, bear- ing directly upon the non-existence of intestinal fistula, and somewhat plainly indicating division of the thoracic duct.-Under this head comes, first in order, Senn's hydrogen gas test. Had this test been applied, without doubt its results would have led to such further investi- gation as would have ultimately led to a correct diagnosis. Second, heat test and miscroscopic examination of fluids discharged. Had the former test been resorted to, these would surely have followed and a correct diagnosis might possibly have been arrived at. Third, shortness of inani- tion period. This, it would appear, should prove, in an otherwise healthy subject, a strong and emphatic diagnostic point indicative of thoracic duct destruction. 9 The adult subject, it is well-known, succumbs to starva- tion in twenty to twenty-four days ; but the phenomenon generally takes place under the withdrawal of all nourish- ment. Here, while the subject was suffering from pneu- monia, and was supposed to have an opening near the stomach through which his food escaped, death still came entirely too soon ; for under the forced rectal alimenta- tion, life should have been maintained for many weeks longer, had the fistula been elsewhere than in the tho- racic duct. Comments Worthy of Record.-In endeavoring to arrive at the probable cause and time of lesion, which it seems to me would be of interest to know, two questions put themselves : Was it the destructive outcome of ex- isting inflammation and formed on, or about, the seven- teenth day ? or, Was it purely traumatic and formed on the day of original injury ? The inflammation about the aortic opening in the diaphragm and adjoining structures, as found in the post-mortem examination, with the inter- vening sixteen days before the fluid came to the surface, combined with the terrifically rapid emaciation after the seventeenth day, would all speak strongly in favor of the first proposition. In my judgment, as formed from a careful noting of the entire case, however, it would be under the latter prop- osition that the actual cause and time should be placed. In support of this, I would argue that the division was sustained in the accident, but happened to be so located within the grasp of the tendinous arch, thrown from one crus of the diaphragm to the other, that immediate, con- tinuous escape of lymph was checked, and the chyle-clot (found upon the removal of the liver) allowed to form in the tissues about the lesion, and so pack and arrange itself there as to temporarily dam up the break. . I believe this condition to have existed up to about the sixteenth day, when the inflamed tissues gave way and the burrowing of chyle began. The main point in support of this theory is to be found 10 in the peculiar tympany appearing on the second day after the injury. The distention, which was not only peculiar in its mode of coming but remarkably so in its stay, could not, at the time, be accounted for. The symptom proved unusually distressing, because of the existing pneumonia, and in our efforts to dispose of it full doses of salts were given, but to no avail. While the bowel discharges were copious and watery, the tympany still remained. This, it now seems, must have depended upon the gas being in the peritoneal cavity, and not in the intestines; and from its existence and its time of ex- istence I infer it to have been a phenomenon coincident to the injury to the duct and also, therefore, a data fixing the time of said injury. As to the cause of such an injury one could hardly conceive its possibility. Whether compression of the lower abdomen could so forcibly crowd its viscera against the diaphragm and upon the, perhaps, well-filled, duct, as to injure it; or whether the squeeze to the chest could have caused such forced respiratory efforts as to produce it; or whether an over-excited diaphragm could cause it by its muscular contractions, are only possibilities to be conjectured, but not shown. How this tube, lying as it does between the aorta and vena cava, could be singled out and divided by causes either indirect and in- flammatory, or direct and traumatic, without also tapping one or the other of its fellow companions, seems to us as incomprehensible, in the study of nature's method of ap- plying her causes in obtaining her effects, as does it seem irrational that she should assign to this poor mortal a death so sure, yet indirect and terrible, as starvation, when she might as well have decreed the tapping of either one of said vessels and let forth his simple life in a single moment, without bodily pain or mental suffering. It will be observed that in the autopsy no evidences of inflammation were to be found other than those in the lung, diaphragm, and the structures immediately adjacent to its aortic opening. These, of course, must be regarded 11 as entirely traumatic. The post-pleural cavity, contain- ing at least two pounds of chyle, with the channel lead- ing to it from the point of rupture in the duct, and also the upper two thirds of the tract through the extra-peri- toneal tissues, were as free from inflammation as though nature had formed and lined them. This latter condition, which positively demonstrates the non-irritability and homogeneousness of chyle to the textural structures of the human body, suggests two points of interest. 1. Could the chemico-physiologist ever be enabled to elaborate out of food-stuffs a product identical with that made in the human digestive laboratory then it would appear the surgeon's skill and ingenuity might lead to some form of venous feeding whereby life might be in- definitely maintained. 2. Bearing upon the much-discussed question of asepsis versus antisepsis the case in point furnishes much practi- cal information favorable to the former theory. Here existed a collection of chyle, pent up between delicate and sensitive tissues for a period of at least sixteen days, without the slightest evidence of inflammatory irritation. Had it been bile, gastric or pancreatic fluid, or even blood, surely no such inaction could have been expected. Upon what, then, could this difference depend other than the possession by the four latter fluids of materials septic to the body tissues, on the one hand, and the asepsis of the sterilized chyle, by virtue of its digestion, on the other ? The mechanical irritation, by contact, of this fluid must certainly be as great as that of sterilized water by boiling at blood heat; and therefore it would appear that the aseptic condition of the surgeon and his materials infuse should become in the end practical, and by all means preferable to the dangerously potent anti- septic remedies used as germicides. 89 Euclid Avenue.
