Knowledge of the "pseudokidney sign" has proven beneficial in order to identify bowel lesions during ultrasound examinations. Numerous causes of the "pseudokidney sign" have been reported. Until now, however, there have been no published reports describing its association with tuberculosis. A description is given of a case of ileal tuberculosis identified by ultrasound, together with an explanation of its cause.

Seven cases of colorectal (five of colonic and two of rectal) tuberculosis are presented. Only one of these patients had associated pulmonary tuberculosis. Radiologic signs of colorectal tuberculosis are nontypical, making the preoperative diagnosis difficult. All five patients with colonic tuberculosis presented with subacute intestinal obstruction and underwent resectional surgery followed by antitubercular chemotherapy. Both patients with rectal tuberculosis presented with rectal strictures and were treated by repeated dilatation combined with antitubercular drugs. All seven patients have been followed for two to ten years and have remained asymptomatic.
Forty-six patients were diagnosed as having schistosomal, tuberculous, or amebic colitis over a two-year period using colonoscopy and biopsy. Both schistosomal and tuberculous colitis could be diagnosed by characteristic endoscopic and histologic features in the majority of cases. Colonoscopy provided the added advantage of endoscopic polypectomy at the diagnostic session itself. The yield of granulomas in tuberculous lesions was 100 percent, although acid-fast bacilli could not be recovered from any. The endoscopic picture of amebic colitis often resembles that of inflammatory bowel disease; hence endoscopic biopsies are of paramount importance in establishing a correct diagnosis, especially in developing countries where both diseases exist with considerable frequency.
Tuberculosis of the rectum is a rare disease. A patient with a miliary pattern of pulmonary tuberculosis had a rectal lesion which proved to be tuberculosis. The patient subsequently developed several opportunistic infections characteristic of acquired immune deficiency syndrome. The clinical, endoscopic, radiologic, and histologic findings of this treatable lesion are presented.

A case is described of tuberculosis of the cecum mimicking carcinoma so closely that a conventional cancer operation was carried out. Ileocecal tuberculosis, reported in the literature, is briefly reviewed with special attention to its incidence, clinical manifestations, clinical investigation, and treatment.

One hundred and seven cases of abdominal tuberculosis were analyzed. There were no specific laboratory or x-ray findings pathognomonic of abdominal tuberculosis. Leukopenia was often found, but was nonspecific. An abdominal tumor was often palpable. A great rarity in our series was profuse hemorrhage from a jejunal tuberculous ulcer; the patient had to be subjected to an emergency operation. In another case tuberculosis appeared in a side-to-side small intestinal anastomosis and in its blind ends, which had developed as a late complication. The diagnosis of abdominal tuberculosis must be confirmed by histologic examination of biopsy specimens; if the results are inconclusive, acid-fast bacilli must be seen or culture should be positive. Guinea-pig inoculation is rarely positive, probably owing to the low virulence of the tuberculous bacteria in abdominal tuberculosis. Good results are obtained with chemotherapy in both intestinal and peritoneal tuberculosis. The complications, obstruction being most usual, must be surgically treated. Resection of the affected segment is the best surgical procedure. For ileocecal tuberculosis, right hemicolectomy was performed. According to the authors, roentgenographic evidence of tuberculosis in the abdomen must always be confirmed by operation, because differentiation from carcinoma and other inflammatory lesions is impossible. For good results after operation, anti-tuberculosis chemotherapy is mandatory.
The etiology of colonic strictures in 263 South African black and Indian patients is presented. Nonmalignant lesions accounted for strictures in two-thirds of the patients and included amebiasis (27), tuberculosis (24), nonspecific colitis (30), ulcerative colitis/Crohn's colitis (11) and other lesions (36). Malignant lesions caused strictures in approximately a third of the black and Indian patients, which is higher than in other reported series in blacks. Accurate clinical diagnosis is difficult and early histologic confirmation is mandatory in order to institute rational management. Strictures of the right colon in the black population are more likely to be benign, except in younger patients. Left-sided colonic strictures have an equal chance of being benign or malignant, and early histologic confirmation is essential. The coexistence of an underlying malignant lesion in association with an inflammatory lesion in an endemic area should always be considered, particularly if it fails to respond to empirical therapy within a short period of time.

One hundred sixty seven children were operated at the Kalawati Saran Children Hospital for acute peritonitis during last 10 years (1978-88). Bowel perforation was seen in 123 cases. Nineteen cases had underlying tubercular enteritis. Preoperative diagnosis was usually difficult. The terminal ileum was affected in 12 and the jejunum in 5 cases. Multiple perforations were seen in 3 cases. Postoperative mortality was high (12/19) and usually attributable to their poor preoperative status.
