A novel suture technique for a large gastric defect after endoscopic full-thickness resection

Endoscopic full-thickness resection (EFTR) is a technique for complete resection of GI lesions without concern about positive vertical margins. However, the difficulty in closing the defect after EFTR limits its clinical application, especially for large lesions. Herein, we present a novel suture technique to achieve complete closure for a large defect after EFTR through a single-channel endoscope.
