Mucosal Snare Resection (MSR) in Non-Submucosal Injection Endoscopic Submucosal Excavation (NSI-ESE) for submucosal tumor may not be the preferable choice: A retrospective study.

ABSTRACT:

Background and aims

Non-submucosal injection endoscopic submucosal excavation (NSI-ESE) and mucosal snare resection-assisted endoscopic submucosal excavation (MSR-ESE) are novel techniques for the treatment of gastric submucosal tumors (SMTs). This study aims to evaluate the feasibility, safety, and efficacy differences between these two methods in the management of gastric SMTs.

Methods

A retrospective analysis was conducted on 95 eligible patients who underwent endoscopic treatment for gastric SMTs between 01/01/2022 and 31/12/2024, including 41 patients treated with MSR-ESE and 54 with NSI-ESE. Differences in operative time, safety, and cost-effectiveness between the two groups were compared, and multivariate linear regression analysis was performed to investigate the ind
