Usefulness of Endoscopic Mucosal Resection Using an Over-the-Scope Clip for Duodenal Neuroendocrine Tumors: A Multicenter Retrospective Comparative Study.

ABSTRACT:

Background and aim

Resection of non-ampullary duodenal neuroendocrine tumors presents technical challenges. This study investigated the efficacy and safety of endoscopic mucosal resection using an over-the-scope clip compared to endoscopic mucosal resection with a ligation device and endoscopic submucosal dissection.

Methods

This retrospective multicenter study included 65 lesions (63 patients), categorized by resection method: endoscopic mucosal resection using an over-the-scope clip (n = 26), endoscopic mucosal resection using a ligation device (n = 17), and endoscopic submucosal dissection (n = 22). Patient characteristics, tumor details, and outcomes were systematically evaluated, with significance at p < 0.05.

Results

Endoscopic mucosal resection using an over-th
