  • Look Inside

 During the last three years colonofiberscopy has been performed in 256 patients in our department complaining of abdominal pain or disturbance of the defecation, and 25 cases of ulcerative colitis were found. In this paper, ulcerative colitis has been investigated from the clinical and endoscopical viewpoint.

 1) According to Roth's clinical classification of ulcerative colitis, 9 cases of them belonged to chronic continuous type, 15 to relapsing-remitting one and 1 to acute fulminating one. However, we differentiated chronic continuous type from relapsing-remitting one in 4 months after the first attack, not in 6 months as reported by Roth, because the clinical symptoms disappeared within 4 months after medical treatment in the greater part of our remitting cases.

 2) Endoscopical findings were classified into three grades for ulcerative colitis; 1st grade(most reliable of ulcerative colitis): pseudopolyposis ; 2nd grade(highly suspicious): multiple ulcers and/or erosions; 3rd grade(suspicious): easy bleeding, abnormal visual capillaries, redness and uneveness of the mucous membrane. In the diagrosis of these 3rd grade ones, dye scattering method was useful for the demonstration of the superficial minute mucosal changes, and for differentiation from non-ulcerative colitis.

 3) Active and inactive stage of the disease were judged endoscopically from the vulnerability of mucosa and this was closely correlated with clinical and histological findings.

 4) The prognosis of ulcerative colitis is hard to tell clinically and endoscopically, but there was observed a significant correlation between the frequency of the defecations and the extension of endoscopical active lesion.
