Problems in the management of abdominal tuberculosis are discussed with reference to 300 surgically verified cases. The protean clinical manifestations depend on the site and extent of the disease, and its complications. Operation was resorted to for complications when diagnosis was in doubt and when intrinsic intestinal disease was proved. Surgery was preceded by antituberculous drugs whenever possible. At operation, the disease was found to involve the alimentary canal in 196 cases; in the remaining 104, only the lymph nodes and/or the peritoneum were affected. Intestinal resection was carried out in 100 cases. Emergency surgery carries a high mortality (18/76) because of toxemia, hypoproteinemia, anemia, etc. Positive histology was obtained in 229 cases. One hundred and seventy-nine cases showed evidence of caseation. Caseation and peritoneal tubercles (103 cases) differentiate intestinal tuberculosis from Crohn's disease. Despite considerable progress made in therapy and prophylaxis during the last quarter of the century, tuberculosis of various sites continues to be a major health hazard in India. The precise prevalence of Koch's disease of the abdomen has not been determined due to lack of a survey in random samples of population. This common malady, however, with its protean profiles and varied complications continues to challenge the diagnostic acumen and therapeutic skill of clinicians practicing various discplines of medicine.
