Usefulness of the S-O clip for duodenal endoscopic submucosal dissection: a propensity score-matched study.

ABSTRACT:

Background/aims

Endoscopic submucosal dissection (ESD) for superficial non-ampullary duodenal tumors (SNADETs) is associated with a high rate of en bloc resection. However, the technique for ESD remains challenging. Recent studies have demonstrated the effectiveness of S-O clips in colonic and gastric ESD. We evaluated the efficacy and safety of duodenal ESD using an S-O clip for SNADETs.

Methods

Consecutive patients who underwent ESD for SNADETs between January 2011 and December 2021 were retrospectively enrolled. Propensity score matching analysis was used to compare patients who underwent duodenal ESD with the S-O clip (S-O group) and those who underwent conventional ESD (control group). Intraoperative perforation rate was the primary outcome, while procedure time and R0
