説明

Forward viewing colonoscope has some limitation in observating the whole colonic area, for example behind a fold or an acute bend. We used forward-lateral viewing changeable colonoscope and evaluated whether it was usefull for dissolving blind area by comparing the ability of the observation using ordinary forward viewing colonoscope.<br> Sixty two cases were examined by forward-lateral viewing changeable scope (provisional name Olympus XCF-DS200I) , and 123 cases were examined by forward viewing scope (Olympus CF200I) . Insertion rate to the cecum was 95.2% by forward viewing scope whereas 95.1% by forward-lateral viewing scope. Lesions in the left side colon were observed in front by using forward-lateral viewing scope even when they situated behind folds and difficult to be observed by forward viewing scope. To look at lesions infront by forward-lateral viewing scope, maneuvers of twisting the scope is required.<br> Therefore observation by forward-lateral viewing scope in the right side colon was more difficult than in the left side colon. During the observation by lateral view system, the endoscopic treatment such as biopsy or polypectomy was impossible. If it were reformed that polypectomy snare wire was accessible in both lateral view and forward view system, it would be more useful.
