Endoscopic submucosal dissection and endoscopic mucosal resection methods for the removal of large sessile polyps

In expert hands, endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) methods can successfully and definitively treat large sessile polyps, thus, eliminating the need for segmental colectomy. The goal should be to utilize ESD whenever feasible as it yields an en bloc specimen. ESD methods can also be used to definitively treat superficial invasive colorectal cancers, which have a very low chance of lymph node involvement.
