Cap-assisted EMR for rectal neuroendocrine tumors: comparisons with conventional EMR and endoscopic submucosal dissection

摘要

Background and Aims: The incidence of rectal neuroendocrine tumors (NETs) is increasing, and most small rectal NETs can be treated endoscopically. Cap-assisted EMR (EMR-C) was suggested as an effective treatment for rectal NETs in a few studies. We aimed to compare the outcomes of conventional EMR, EMR-C, and endoscopic submucosal dissection (ESD) for the treatment of rectal NETs.
