Gastrointestinal tract tuberculosis: a study of 102 cases including 55 hemicolectomies.

Tuberculosis continues to be a major health problem in India. Our experience of 102 cases of gastrointestinal tract tuberculosis is presented. Eighty-one of these patients experienced obstructive symptoms, 62 had radiographic evidence of intestinal obstruction, and four had bowel perforation. Lymphadenopathy was present in 16 patients and pulmonary tuberculosis in 28. The commonest sites of bowel involvement were ileo-caecal, ileum and ascending colon. Duodenal lesions were seen in three cases and in another three there was isolated appendicular involvement. Right hemicolectomy was necessary in 55 of the 74 patients who had surgical exploration. Histopathological reports were available in 88 subjects. The various radiographic manifestations of tuberculosis of the bowel are discussed. Radiologically and sometimes even on histopathology, differentiation of ileo-caecal tuberculosis from Crohn's ileo-colitis may prove impossible.
