A clinical study of tuberculous colitis.

During the last 8 years, the diagnosis of tuberculous colitis has been made radiologically in 22 cases. Twelve were confirmed by histological or bacteriological evidences. The X-ray findings are classified into three types as follows: Type A, showing an extensive scarred area in the ileocecum and ascending colon. Type B, showing annular stricture in the ascending colon and dilatation of its oral side. Type C, showing pouchformation (pseudo-diverticulum) and deformity in the cecum. We emphasize that histological examination and culture of the biopsy specimens by endoscopy were useful for the diagnosis of tuberculous colitis. Furthermore, radiologic changes of the colon by administration of antituberculous drugs were observed.
