Prototype holder adequately supports the overtube in balloon-assisted endoscopic submucosal dissection

摘要

Endoscopic maneuverability is essential for colorectal endo-' scopic submucosal dissection (ESD). If the necessary degree of endoscopic control cannot be achieved with conventional colonoscopy, the intrinsic design of balloon-assisted ESD (BAESD) enhances endoscopic maneuverability and provides an effective alternative to conventional colonoscopy. However, BAESD requires an assistant to hold the overtube throughout the procedure. Therefore, we devised a prototype mechanical overtube holder as an alternative to an assistant (Figs 1,2). We analyzed our results to determine whether the prototype holder takes the place of an assistant.
