In our clinic, 38 patients were diagnosed as proctitis-type ulcerative colitis in these 15 years by the initial clinical assessments.<BR>Among the 38 patients, 21 were followed up over 1 year, i.e. over 1 year in 5 patients, over 2 years in 5, over 3 years in 4 and over 5 years in 7.<BR>The extent of the disease was determined by barium enema and colonofiberscopy, without using magnifying colonoscopy nor dye-spraying method. During the periods of the follow-up study, 2 patients developed total or left-sided colitis. In the other 19 patients (91%), the extents of the disease were almost unchanged. On the other hand, in 22 patients with total or left-sided colitis followed up over 2 years, 3 developed proctitis-type colitis.<BR>These studies indicate most patients with proctitis-type colitis are unchanged in the disease in the course. However, in a few patients there is possible risk to develop total colitis.
