A newly designed transparent plastic cap fitted to the tip of colonoscope was evaluated regarding to insertion of scope, visual field, polypectomy and mucosectomy. A transparent plastic cap has a 17-mm in outer diameter, l5-mm in inner diameter and 10-mm in length and is easily attached to the tip of the colonoscope. This method attained a good continuous visual field during insertion of scope and the lens of scope never contacted to the surface of mucosa. We could recognize easily the continuity of lumen through the wall of this cap at the turning point. Blind part of mucosa behind the fold of colon could be well observed by the oppresion of the cap. During mucosectomy after local injection of saline solution the target mucosa was sucked inside the cap and snared under a full endoscopic suction. We call this procedure EMRC (Endoscopic mucosal resection using a cap-fitted endoscope). We conclude that colonoscopy wearing a transparent cap is a very useful procedure not only as a diagnostic procedure but a therapeutic measure.
