A CASE OF ABSCESS OF THE LIVER FOLLOWING AMCEBIC DYSENTERY: WITH REMARKS. By J. H. MUSSER, M.D., ASSISTANT PROFESSOR OF CLINICAL MEDICINE, UNIVERSITY OF PENNSYLVANIA ; PHYSICIAN TO THE PHILADELPHIA AND THE PRESRYTERIAN HOSPITALS ; AND DEFOREST WILLARD, M.D., SURGEON TO THE PRESBYTERIAN HOSPITAL; PROFESSOR OF ORTHOPEDIC SURGERY, UNIVERSITY OF PENNSYLVANIA. [Read February 22, 1893.] The patient, a male, aged thirty-one years, white, galvanizer by occupation, was admitted to the wards of the Presbyterian Hospital on the 16th of November last. He sought the hospital on account of prostration following an attack of dysentery. It appears that throughout the entire summer he had been ailing. He lost his appetite, and was dull and depressed in spirits. He had little aptitude for exertion, and observed that his bowels were irreg- ular, constipation alternating with diarrhoea. At the same time he felt con- siderable soreness in the loins when lying down. Vertigo troubled him very much. The symptoms increased in severity and seemed to culminate in an attack of dysentery seven weeks prior to admission. The attack was, clinically, like that of the amoebic variety. The stools were bloody, contained mucus, and were discharged with tormina and tenesmus. During the seven weeks of illness he had several exacerbations, each followed by an amelioration of symptoms. Four weeks ago vesical tenesmus began, with frequent micturition. Three days prior to admission the diarrhoea ceased. Before detailing the state of the patient at the time of admission, it may be well to remark that he resided in this city in a most unsanitary neighborhood, and had been accustomed to drink water from the usual city supply. For possible aid in the diagnosis we further gleaned from the patient that he was a widower, the father of five healthy children, that he had smallpox, besides the usual diseases of childhood, and typhoid fever at twenty-one; that his personal history regarding habits, etc., was good, and that he never had any venereal disease. His mother, one sister and three brothers are in good health. The father died of some gastric affection, and two sisters of phthisis florida. The grandparents of the previous generation were very healthy. On admission the patient was very weak, emaciated, and pale. The anaemia was striking, and on examination of the blood it was found so 2 MUSSER, WILLARD, reduced that only 2,800,000 red corpuscles were counted in a c.mm., with pro- portionate decrease of the white corpuscles. The patient was so weak as to be compelled to remain in bed. He weighed thirty pounds less than in health. The cerebro spinal system was free from disease. He had no appetite, but a furred tongue and some flatulent dyspepsia. His bowels had not been moved for twenty-four hours. An enema was necessary to relieve the impaction. No mucus was passed. The abdomen was not distended. The liver and spleen were not enlarged. The lungs were normal. At the pulmonary and mitral areas systolic mur- murs, low in pitch, were heard, due to anaemia. Murmurs from similar cause were heard in the vessels of the neck. The urine was abundant, of low specific gravity, and did not contain pathological elements. Diagnosis : anaemia following dysentery. With rest and careful feeding, strength returned and the color improved. On December 1st the patient began to complain of pain in the lower portion of the right chest, anteriorly. It increased in severity and soon became localized to an area the size of a half-dollar in the seventh interspace, anterior axillary line. On account of its severity, the patient was compelled to lie on his back. Movement increased the pain, after a short time, and lying on the left side or sitting in the erect position caused agony. The liver was enlarged upward. The upper limit of dulness was found at the fifth rib anteriorly. The lower border could not be felt, and on percussion the limit of dulness was not beyond the edge of the ribs. The remaining organs were normal. The cardiac and vascular murmurs had lessened and the blood increased in richness to 3,800,000 red corpuscles per c.mm. Appetite remained poor, and there was constipation. Has gained in flesh and strength. 1th. Pain has continued in spite of blisters and other external applications. Morphine was required. The liver continued to enlarge. The upper border of the liver in the mid-clavicular line begins in the fourth interspace, in the axillary region in the fifth interspace, and posteriorly, one inch below angle of scapula. The hepatic region has increased in size, but there is no local bulging. The lower right chest does not expand freely as compared with the left. There are no friction sounds or signs of pleural effusion. Anaemia much improved, and patient has gained flesh. There has been no fever but occa- sional sweats. Appetite not improved. 15fA. Pain not relieved. Liver about the same size. The upper limit of dulness is not movable. The organ does not extend beyond the margin of the ribs. When the patient turns on the left side the extent of dulness lessens in the axillary region, and is found between the fifth and seventh ribs. On his back the lower border of dulness extends to the margin of the ribs. The dulness begins at the ninth rib, in mid-scapular line. Appetite poor. No fever. Strength greater. With a fine hypodermatic needle introduced in anterior axillary line in seventh interspace, pus was withdrawn. Admitted to surgical ward. During the time the patient was in the hospital ward, the stools were not studied because of the absence of mucus or any material likely to contain amoebae. In fact, constipation had to be combated. Nevertheless, the diagnosis of abscess of the liver secondary to dysentery was made because of ABSCESS OF THE LIVER. 3 this possible sequence, and because of painful enlargement of the organ-an enlargement that could not be satisfactorily explained by any other patho- logical process. Persistent poor appetite, in spite of improvement in general health, was also believed to be significant of the presence of pus. The above conclusion was arrived at notwithstanding the absence of fever. The interesting features of the case are worthy of consid- eration seriatim. 1. Improvement in general health in spite of the extensive sup- puration. This seemed to the writer remarkable. The blood-count showed improvement; the weight and strength increased. If to this is added the absence of fever (considered in the next paragraph), it is seen that the general phenomena did not indicate the gravity of the local process. 2. Fever. The absence of fever is worthy of comment. The temperature did not vary from the normal during the entire time in the medical ward. At different periods a two-hour temperature observation was taken, with negative results. Rigors were never present, and slight sweats only occasionally noticed. The latter were not sufficiently pronounced to be suggestive. 3. Loss of appetite. The. writer has previously suggested the importance of this symptom in obscure cases of suppuration. If the loss of appetite can be explained in any other way, as by local gastric disorder, it is not noteworthy. But if there is loss of appetite without cause, and if such impairment is attended by slight nausea or revulsion at the sight of food, or after a few portions are taken, it is highly suggestive of suppuration and pus-absorption. The writer has seen these relations most strikingly in pelvic disease and suppu- ration about the appendix. The symptom is not an indication of the seat of pus, but that somewhere pus-formation, with its imprison- ment, is in progress. Unexplained loss of appetite, without fever, but with failure in health, may serve to explain the nature of a local process which does not show any signs of pus. 4. Pain. At first, on account of the profound anaemia, intercostal neuralgia was thought to be the cause of the localized pain. Although the anaemia improved, the pain increased in severity and was the cause of attention to the liver. The pain was increased by pressure and by movement. No localized peritonitis or pleuritis could be detected to explain the symptom. Pain in the right shoulder was not observed. 5. Enlargement of the liver and of the affected side. The exten- sion of the enlargement upward was of interest. The writer has had 4 MUSSER, WILLARD, the privilege of observing a number of cases of hepatic abscess. In all save one the increase in size of the organ was downward, and the organ itself, or the portion in which the abscess was situated, could be readily outlined below the ribs in the hypochondriac or epigastric regions. While there was no distinct localized bulging, an enlarge- ment of the right lower half of the chest could easily be detected. 6. Pleural friction sounds. It may be noted that friction sounds and other physical signs of inflammation above the diaphragm were absent. This is all the more remarkable because of the close prox- imity of the abscess to the diaphragm. 7. Character of the pus. It partook of the character so well described by Councilman and Lafleur, of an anchovy-sauce-like fluid. The .amoeba dysenterica was found readily. In addition to the usual appearances of purulent fluid and pigment, leucin and tyrosin crystals were found in abundance. The case shows that amoebic dysentery may arise in this locality. Resume: Amoebic dysentery; anaemia; pain in the hepatic region, enlargement of the liver upward ; loss of appetite. On exploration, pus found. Diagnosis : abscess of the liver. Operation.-Admitted to surgical ward December 17, 1892. The patient suffers no pain. Temperature normal. Says that he feels as well as he ever did in his life. Physical signs as before described by Dr. Musser. Large aspirator needle in the seventh interspace, at the depth of two and a half inches, secured pus. With- drew the trocar and replaced it with a blunt plunger. Camila used as a guide to the abscess, and kept in situ until pus was reached with the knife. An incision, three inches long, was made in the seventh inter- space ; three inches of the seventh rib were resected subperiosteally without hemorrhage and without opening the pleural cavity. When the pleural cavity was opened by an incision, the lung slid upward, but there was no great collapse of the lung, nor great depression of the patient. The pulse became slightly more rapid, but did not lose force. Pressure upon the right ribs permitted only a small amount of air to enter the pleural cavity. The pleura was then slit two inches. With a long curved needle four catgut sutures were passed from the parietal layer of the pleura through the diaphragmatic layer, and out again through the parietal layer. Two of these stitches were parallel to and a little longer than the wound in the pleura; the other two united the two ends of these first sutures well beyond the angles of the pleural incision. These stitches enclosed a ABSCESS OF THE LIVER. 5 rectangular parallelogram, and were tied separately over the four sides surrounding the area of incision, thus closing the pleural cavity against air and pus. The stitches were tied lightly, so as to approx- imate the two layers of the pleura, and not so tightly as to cut the tissues, since adhesive inflammation only was desired. With the canula as a guide, the liver was then opened through the diaphragm, and a pint of chocolate-colored pus evacuated. The cavity was thoroughly washed out with hot distilled water, and a large drainage-tube inserted. A finger could be carried round the walls of the cavity, but could not detect any softened spots down- ward. The finger was unable to reach the bottom of the cavity. The wound was packed with sterilized gauze. No hemorrhage occurred throughout the operation. The amount of pneumothorax was slight. The patient suffered no dyspnoea from ether. His pulse and general condition were good. Dyspnoea during the remainder of the day and night of operation was very marked, but there was but little cough, and no serious collapse of the lung. The temperature on the third day was normal. There were no signs of pleurisy, and the pneumothorax was dimin- ishing. The patient was much stronger. On the sixth day he was greatly improved. The quantity of the pus steadily decreased. His appetite was good, and his general health improved. The drainage-tube was slightly shortened at every dressing, and was removed entirely at the end of the fifth week. The patient had no bad symptoms whatever during the course of the treatment. At present writing the discharge of pus amounts only to a few drops daily. The main interest in this case consists in the route taken to reach the pus. The suturing of the two pleural surfaces in contact over a parallelogram of tissue so as to prevent infection from entrance of air and pus was, in this instance, effective. The prompt adhesion of two pleural surfaces brought gently into contact has been illustrated by myself in various operations upon the pleura of dogs,1 the adhe- sions having taken place, in some instances, within twenty-four hours, and in all without pain or evidences of pleurisy. These experiments made me hopeful of union in the human subject, and I was not disappointed. 1 " Pneumonotomy and Pneumonectomy," Transactions Philadelphia College of Physicians, November, 1892 ; " Intra-thoracic Surgery," Transactions Am.

The sub-periosteal resection of rib permits late opening of the pleural cavity, which is important. After the opening is made, if violent dyspnoea results, partial closure of the opening by pressure or a plug of gauze is helpful. Again, the retention of the canula as a guide to the pus is a helpful procedure, since good surgeons have missed a pus collection in the liver, even when their incision was within a quarter of an inch of it.
