Up to date, with remarkable advances of colonofiberscopy, we have been able to observe endoscopically almost all parts of colonic mucosa. Furthermore, for observing minute changes of colonic mucosa, several new approaches have been tried, as one of which, we have already applied the dye scattering method in colonof iberscopy. As the another new approach, we have made a special type of colonof iberscope, type CF-MB-M (Olympus), by which we can easily magnify the colonic mucosa and observe its close-up picture. The new fiberscope is 1110mm in its length and 14mm in diameter of its flexible portion, and its optical apparatus comes close to 5 mm from the colonic mucosa. This fiberscope has been applied to 51 cases in our clinic, and the results obtained were as follows; 1) By means of this f iberscope, the minute findings of the colonic mucosa was more clearly observed than usual. 2) Furthermore, with aids of methylene blue dye scattering method, the endoscopical and/or clinical stages were easily classified in 22 cases of ulcerative colitis. Especially, we could easily differenciate the quiescent stage of this disease from the normal colonic mucosa by observing the minute abnormal surface appearances, such as minute obscure depression or disorder of mucosal structures.
