Abstract
The definite diagnosis of the colonic tuberculosis by biopsy have been considered to be difficult until today. In 6 (85.7%) of 7 cases without antituberculous therapy, tubercle bacilli were cultured from biopsy specimens. There was no relation between cultivated results and shape of unlcers, i. e. size or depth. It is considered that tuberle bacilli always exist on the bottom of active ulcers of and that culture of tubercle is more effective than histological examination for the definite diagnosis of the colonic tuberculosis. It has become clear that cases without typical "scarred area with discoloration" exist on the follow-up radiological studies of non-operated cases of colonic tuberculosis, definitely diagnosed. We could classify X-ray patterns of colonic tuberculosis into 3 groups in the investigation of these atypical cases.
