Endoscopic pictures of healed total colitis were studied. An atrophic type was predominant among the cases healed with medical treatment (71%). On the contrary, a polyposis type was 50% in operated cases. Cases with inflammatory diverticulosis proved to be not so infrequent in our series. In most cases, the rectum showed the atrophic type. Inflammatory polyposis and diverticulosis were observed in the colon irrespective of anatomic location. Endoscopic findings of the healed ulcerative colitis was almost the same in the first and the following attacks. Polyposis vanished after three or more years of remission. Cases with deep ulceration at the active stage resulted in polyposis and/or diverticulosis type. Inflammatory diverticula ranged from deep to shallow, wide to narrow. They were established soon after the remission in 4 cases. However, they appeared after one year in 2 cases. In one case diverticula became deeper and extensive with a lapse of time. They vanished after a long period of remission except deep ones. Two cases with stenosis and one case with mesh-like lesion were noticed as rare examples of healed lesions.
