 It goes without saying that in the diagnosis of ulcerative colitis, x-ray examination and endoscopic study are both indispensable like two wheels of a cart; of more importance than any other diagnostic method. This is especially true in endoscopic findings as they furnish the most important materials for determination of the actual aspect and stage of this disease. However, even when exact findings can be obtained by recto-sigmoidoscopy, its extent or depth of examination is confined at most up to the flexul-a recto-sigmoidalis, being unable to photograph or observe under direct view the segment oral beyond the said flexura. Although a preliminary step in photographying the mucosa all over the colon has been initiated by the sigmoidocamera devised by Prof. Matsunaga, it involves many drawbacks such as blind photograph and difficult technique in inserting this camerra in a deeper segment. All these difficulties are now obviated in the present colonofiberscope, enabling the examiner not only to observe and photograph the mucosa of the colon under direct view, but to perform repeatedly biopsy as well, with a rise in the ratio of successful insertion of this instrument into a far deeper segment of the bowel. Of 1.85 m length, the colonofiberscope now being employed is able to reach, over beyond the sigmoid, the descending colon in 74 per cent of cases examined, whereas the sigmoid camera has only been successful in 25 per cent. In addition to this, observation and photography of the mucosa of the cecum and the ascending colon is now going to be feasible. For the diagnosis of right-side ulcerative colitis, relatively localized changes in the ascending colon and of mucosal changes of the rectum in mild cases, the colonofiberscope is a most appropriate diagnostic measure. This fact has been outlined in this paper in each type of ulcerative colitis in addition to several illustrative cases. Brief comments have also been made on practical methods of endoscopic examination of the colon, including the colonofiberscope.
