Abstract
Although mycobacterium tuberculosis infects us via respiratory tract and injuresmainly lungs, it injures other various organs, including digestive system. It is reported that19.4% of the patients with intestinal tuberculosis suffer from active pulmonary tuberculosis. However there are few reports that investigate the tuberculous changes of lowerdigestive tract in patients with active pulmonary tuberculosis. To investigate tuberculouschange in louver digestive bract of patients with active pulmonary tuberculosis, vvho haven not any digestive symptom, we performed total colonoscopy to thern. In 3 of 6 patients, aphtoid lesions were found in ileocecal lesions. And then thesechanges were cured by treatment of antituberculous drugs. But we could not recognize theorigins of these changes bacteriologically, histologically or endoscopically.
