Clinical Outcomes of Patients with Small Rectal Neuroendocrine Tumors Treated Using Endoscopic Submucosal Resection with a Ligation Device.

Background/aims: The therapeutic strategies for small rectal neuroendocrine tumors (NETs) have not been standardized. We examined the efficacy and safety of endoscopic submucosal resection with a ligation device (ESMR-L) and the long-term outcomes after endoscopic treatment.

Methods: A total of 181 patients with rectal NETs <10 mm who were treated between May 2002 and May 2017 were retrospectively enrolled.
