Tubercular Peritonitis

This form of disease is by no means uniform in its first symptoms or in its progress. The only things uniformly attending it are tubercles on the peritoneum and more or less of inflammatory effusion, chiefly lymph and serum; tumor and hardness of the bowels, general or local; deranged function of the stomach and intestines; emaciation; and extreme fatality.

In some cases the invasion is acute and marked—a chill followed by fever, vomiting, early development of meteorism, and in a few days a point or points of resistance to pressure, but not necessarily dulness on percussion. In a few days the febrile action and the meteorism may subside, leaving the symptoms of local peritonitis. But we have not long to wait for a renewal of them and an evident extension of the inflammatory action. Remission and relapse alternate at varying intervals, until the whole extent of the peritoneal surface seems to be involved in inflammation. With this mode of development meteorism may not be renewed in the most common way. The lymphy product of inflammation may so bind the intestines to the posterior walls of the abdomen that they cannot extend forward, but are pushed upward against the liver and diaphragm, and so encroach on the thoracic space. But then the anterior parietes are tense and hard, and do not move in respiration. The febrile heat may not continue more than two or three months, but the pulse will be frequent to the end. There will be a thinning of bowel walls, and here and there a knuckle of adherent intestines may cause some prominence and give some resonance on percussion. There will be also occasional vomiting, and the dejections will be irregular—maybe only deficient or thin; there may be an alternation of constipation and diarrhoea.

Tuberculous ulcerations of the mucous layer of the bowels is not uncommon in tubercular peritonitis, and these ulcers have in rare cases perforated and allowed the fecal matter to accumulate in considerable quantity in a sac limited by previous adhesions. In all forms of tubercular peritonitis death is caused as often by grave complications as by what appears to be the primary disease. The affection occurs in probably every instance in those who had at the beginning, or had acquired in its progress, what we call the tubercular diathesis. We are not surprised, therefore, to find on inspection a wide diffusion of tubercles in the body, particularly on other serous membranes, and in the lungs. Death may occur, then, from phthisis pulmonalis or from pleurisy or meningitis, as well as from the exhaustion and accidents of the peritoneal disease. The effusion serum or turbid serum is very common in tubercular peritonitis, and can be recognized by the dulness it produces in part of the cavity, and sometimes by fluctuation. It is often sacculated, but it is not constantly found after death, it having been absorbed before, and perhaps long before, that event.

In other cases the invasion of the disease is stealthy and deceiving. It comes so quietly that the patient is not conscious of any local disorder beyond a dyspepsia and irregular action of the bowels. He has a pulse of growing frequency, but if he knows it he ascribes it to his dyspepsia. He is slowly losing flesh and strength; this he accounts for in the same way. At length a perceptible swelling of the bowels attracts his attention. At this stage the physician finds that the swollen bowels are tympanitic everywhere or only in the upper, while there is evidence of fluid effusion in the more depending, parts. He discovers some, it may be little, tenderness on pressure, and a pulse of 85, or maybe 90, increasing in frequency toward evening. The appetite is poor, the digestion slow, and occasionally there is vomiting; the complexion is pale and a little dingy; the skin of the abdomen may be dry and rough or may be natural; some colicky pains have been or soon will be felt. From this point the disease gradually advances. The distension of the bowels slowly increases or they are firmly retracted; the emaciation increases; the strength diminishes; there is often cough, which is generally dry; the bowels are slow or diarrhoea alternates with constipation; with the distended bowels there is always more than natural resonance on percussion, except when there is fluid effusion, though not often the full tympanitic sound observed in acute diffuse peritonitis. This resonance is not equal, always, in different parts of the abdomen; the respiration is embarrassed and almost wholly thoracic. The abdomen is often as large as that of a female at full term of pregnancy, and indeed the condition has been mistaken for pregnancy. This is an inexcusable blunder in a case like that which I have in mind—a young unmarried woman. She had no dulness on percussion in the space that would be occupied by the gravid uterus, but rather resonance. The case might have been a little less clear if there had been fluid effusion in the abdominal cavity, but if this were not encysted it would flow from one side of the abdomen to the other when the patient turned correspondingly in bed; if it was encysted, there would be small chances that it would have the shape and position of the gravid uterus; if it had, there would be no chance of hearing in it the foetal heart or feeling the foetal movements; and after all this there remains the experimentum crucis—a vaginal examination.

At first the diagnosis is unavoidably uncertain. Some aid is found, possibly, in the medical history of the family, in tuberculous antecedents, yet I remember cases in which no phthisis could be found in any living or dead member of the family on the paternal or maternal side as far back as it could be traced. Some aid is found if the patient himself has any of the physical or rational indications of pulmonary phthisis, and yet there are recorded cases in which the abdominal symptoms were the first to appear. The prominent German physicians attach great importance to the pre-existence of a cheesy mass or degeneration somewhere in the body as the real parent of tubercles wherever they appear. The truth of this doctrine, I do not think, has received anything like universal recognition; and if it had, as this cheesy degeneration is often, perhaps commonly, only discoverable after death, it could rarely give any assistance in diagnosis, so that the early diagnosis is always difficult, and a very early one often impossible. But as time goes on, and the symptoms are better defined and show themselves one after another as they are above described, it seems as if a careful observer could not confound it with anything except perhaps one of the other forms of chronic peritonitis or cancerous peritonitis. As to the latter, the cough which exists in most cases of tubercular peritonitis will assist in the distinction, but a physical examination much more; for a cough does not always attend phthisis when this disease exists; for example, I visited a daughter of one of the distinguished gentlemen of Vermont. She had had the bowel symptoms that indicated tubercular peritonitis for eight or ten months, and the diagnosis was not difficult. Remembering Louis's opinion that if tubercles invade any other part of the body, they are likely to be found at the same time in the lungs and in a more advanced condition, I examined the lungs, and found in the upper part of the right a cavity so large that it could have received a fist. I was only surprised by the fact that she did not cough, and had not coughed. She herself assured me of that (she was twenty-one years old); her physician, who was present at the visit, had never heard her cough, and had no suspicion of any pulmonary complication; but, more than all, her mother, who had walked with her, slept with her, eaten with her, travelled with her, and from the beginning of the illness had not been out of her company more than twenty minutes in any twenty-four hours since the disease began, had never heard her cough. Here, then, the nervous deviation to the abdomen, or whatever else it may have been, had so benumbed the sensibility of the pulmonary nerves that the alarm-bell of phthisis had never been sounded; but the cavity, had there been any doubt whether the bowel disease was cancerous or tuberculous, would have almost fully settled the question. But more of the peculiarities of cancerous peritonitis a little farther on.

The lesions of this disease (or its pathological anatomy) differ considerably, but the differences are in the amount of tuberculous deposit and the secondary results, not in the real nature of the disease. Lebert has published among his plates of pathological anatomy one which shows the peritoneum thickly sprinkled over with small tuberculous grains, and represents each particular grain surrounded by a little zone of inflammatory injection. There is yet no exudation, but that would soon follow. A fibrinous exudation will soon come over this primary deposit, and undergo a kind of organization, or at least get blood-vessels, which in their turn can furnish the material for a new crop of tubercles. These again provoke a new layer of fibrous tissue, which also becomes studded with tubercles, and so on, till a thick covering is formed over the intestines. But the same material is interposed between their folds, separating one from another and compressing them and diminishing their calibre; at the same time this agglomerated mass is firmly adherent to the abdominal walls everywhere. The new material may have a thickness of half an inch or even more. I remember how surprised and confused I was when I made my first inspection of such a case. The abdominal walls were cut through, but they could not be lifted from the intestines, but were firmly adherent to something. They were carefully dissected off and the bowel cavity (?) exposed; there was apparently an immense tumor filling the whole space: no intestines, no viscera, could be seen. A section was made through this mass from above downward, and another parallel with it and an inch distant from it, and this part removed. It appeared like a large, hard tumor, through which the intestine made several perforations. The new material appeared to be fibrous, with grayish-white tubercles sprinkled in through it everywhere, and pretty abundantly. In another case this fibro-tubercular material may occupy one part of the abdomen, and a large serous cyst or serous cysts another. The tuberculo-fibrous material may be found in markedly less quantity than is so far described, till there will be no more than in a case from Ziemssen's clinique, quoted by Bauer: "In the peritoneal cavity about four liters of yellowish-brown, slightly turbid fluid. Omentum thickened, stretched, adherent to the anterior wall of the abdomen and beset with hemorrhages; the same was true of the parietal peritoneum; between the hemorrhages whitish-yellow and entirely white tubercles occur, varying in size from the head of a pin to a lentil. The intestinal serous membrane was similarly invaded. The intestines intensely inflated; a number of ulcers on the mucous membrane, one approaching perforation. Covering of the liver thickened by fibrinous deposition."

The lungs and serous membranes generally will, in all probability, show more or less of tubercular deposit, the pericardium less frequently than the others.

The result in this affection, after it is fully established, is believed to be uniformly fatal, and at its commencement the difficulty of diagnosis may lead one to doubt whether his apparent success is anything better than apparent. Still, a plan which I have relied on is, I believe, worth announcing. As soon as the disease is recognized the patient is put upon the use of the iodide of potassium and the iodide of iron, in full average doses, and a solution of iodine in olive oil is applied to the whole surface of the abdomen by such gentle friction as will produce no pain; and after a minute or two of such friction the oil is brushed thinly over the surface and the whole covered with oiled silk. This dressing is repeated twice a day. The quantity of iodine to an ounce of oil will vary considerably in different persons; for some, seven to ten grains will be enough; for others, thirty will be needed. The iron is to make the application moderately irritating, and if it produce pinhead blisters or blisters a little larger, all the better. When the application becomes painful the oil is washed off, and the application is not renewed for two or three days. In this manner it may be continued for two or three months. Meantime, the patient is put upon the diet and regimen of the consumptive, the appetite encouraged; he takes sustaining food, with plenty of milk and cream, or cod-liver oil, as much fresh air as possible, and friction is applied to other parts of the body with dry flannel.
