Outcome of Endoscopic Submucosal Dissection for Rectal Neuroendocrine Neoplasms - A Multicentre Study

Aims Recent guidelines recommend advanced endoscopic resection techniques, such as Endoscopic Submucosal Dissection (ESD), for the treatment of rectal neuroendocrine neoplasms (R-NENs) under 15mm due to high rate of positive margins at Endoscopic Mucosal Resection (EMR) (1,2). Data for supporting ESD on R-NENs are scarce. We retrospectively ruled in a western cohort of patients who had ESD for R-NENs and a post ESD endoscopic follow-up to evaluate its efficacy.
