1. Previously we used side-viewing fibergastroscope type, CL (FGS-CL) for the observation of the colon as the basic study of the fibercolonoscopy. Of the 27 cases examined by FGS-CL, we succeeded in insertion into the transverse colon in 2 cases and into the descending colon in 13 cases, comprising 56% (15/27).The figure of the scope along the sigmoid colon was found important for the further insertion. We presented one case of colon carcinoma successfully observed and biopsied by side-viewing scope.2. Owing to the recent advance in the fibercolonoscope, thorough examination of the entire colon has become possible. Of the 27 cases examined by, we introduced the fibercolonoscope (FCS, Machida) into the transverse colon and the cecum in 84%. We explained how we succeeded in introduction of the FCS into the cecum, and emphasized the difficulty in passing the sigmoid colon and especially the transverse colon.3. We introduced the fibersigmoidscope (FSS, Machida), produced for the observation of the sigmoid colon where lesions are common next to the rectum.In all the cases examined by the FSS we succeeded in observation of the sigmoidcolon. We showed one case of carcinoma of the sigmoid colon which previously we failed to find both by barium enema and romanoscopy.4. Finally we compared the efficiencies of side- and frontal-viewing fiberscope for the colonic examination.
