    Abstract:
    BACKGROUND: There has been a resurgence of interest in intestinal tuberculosis because of acquired immunodeficiency syndrome (AIDS) epidemic sweeping our country. Role of colonoscopy and colonoscopy directed histology for diagnosing the disease have been emphasised since last few years. AIMS AND OBJECTIVES: To know the colonoscopic features in patients with intestinal tuberculosis and to study the clinicopathological findings in the same. METHODS: We studied twenty-one patients with intestinal tuberculosis referred to us between 1993-1997. Colonoscopy was done in all patients and biopsy specimens were collected from the site of lesion during the procedure. RESULTS: Ileocaecal disease was found in 9 patients, ileocaecal with contiguous ascending colon involvement in eight and segmental colonic tuberculosis in four cases. The colonoscopic findings included nodules in seven patients, nodules with ulcerations in three, ulcerations alone in seven, nodules with strictures in three and polypoidal mass in one patient. Eight cases revealed granuloma on histopathology. CONCLUSIONS: Though bacteriological and histological assessment of tissue is essential to differentiate tuberculosis from other disorders, we stress the importance of colonoscopic appearances in diagnosing tuberculosis. We also recommend antituberculous chemotherapy in patients with high clinical suspicion of tuberculosis on the basis of colonoscopic appearance alone after ruling other causes on histopathological examination.
