Endoscopic submucosal resection of gastric subepithelial lesions smaller than 20 mm: a comparison of saline solution-assisted snare and cap band mucosectomy techniques

Abstract

Background and Aims: Application of endoscopic submucosal resection (ESMR) in the management of gastric subepithelial lesions (GSLs) less than 20 mm is gradually increasing because it allows diagnosis and treatment at the same operative session. In this study, we compare and evaluate the benefits of ESMR with an endoscopic cap band mucosectomy technique or saline solution-assisted snare technique in GSLs smaller than 20 mm.
