Core Tip
Core Tip: The primary innovation of this study is the first-time integration of the endoscopic traction technique with endoscopic subserosal dissection, establishing a novel endoscopic strategy for managing gastric subepithelial tumors originating from the muscularis propria layer. This approach integrates the key advantages of both endoscopic subserosal dissection and traction techniques, enabling complete resection of the lesion while preserving serosal integrity - thereby substantially reducing the risk of serious complications. Moreover, it reduces procedural difficulty and enhances reproducibility.
