Submucosal endoscopy with mucosal resection (SEMR): a new hybrid technique of endoscopic submucosal balloon dissection in the porcine rectosigmoid colon

摘要

Background We developed a technique, submucosal endoscopy with mucosal resection (SEMR) intended to make endoscopic submucosal dissection easier and safer. With this technique, the submucosal layer is balloon dissected in lieu of electrosurgical knife dissection. The aim of this study was to further evaluate SEMR in the porcine rectum and colon.
