Carving Out a Place for Endoscopic Submucosal Dissection

The larger the polyp, the greater the cancer risk. Among polyps >20 mm in size, the risk may exceed 10%.1 Although some polyps portray overt signs of cancer through their pit pattern or a depressed morphology,2,3 others are covert without such worrisome characteristics. Cancers with minimal invasion into the submucosa can be removed completely by endoscopic resection and, in the absence of lymphovascular invasion or poor differentiation, for almost all complete resection equates to cure.4 To prove a healthy margin and confirm complete resection, the polyp has to be removed in 1 piece (en bloc).
