Core Tip
Core Tip: This retrospective cohort study compared traction-preclosure-assisted endoscopic full-thickness resection (EFTR) with conventional EFTR for gastric subepithelial tumors. traction-preclosure-EFTR improved complete resection rates, shortened operation and closure times, and reduced pneumoperitoneum incidence while enhancing postoperative quality of life (higher EuroQol visual analogue scale and health utility values) without increasing recurrence risk, demonstrating superior efficacy and safety.
