Traction-preclosure-assisted vs conventional endoscopic full-thickness resection for gastric subepithelial tumors: Safety, efficacy in a retrospective cohort (with video)

BACKGROUND Gastric subepithelial tumors (SETs), commonly encountered in gastrointestinal practice, require precise and complete resection to prevent recurrence and malignant transformation. AIM To compare efficacy, safety, and clinical outcomes between traction-preclosure (TPC)-assisted endoscopic full-thickness resection (EFTR) and conventional EFTR for gastric SETs. METHODS We retrospectively analyzed 214 patients who underwent EFTR for gastric SETs, assigning them to the conventional EFTR (n
