Objective To evaluate the perforation repair method of purse-string suture with single channel after gastroscopy endoscopic submucosal resection (ESD) in treating gastric submucosalal stromal tumor originating from muscularis propria lay of gastric fundus. Methods 15 patients with GIST from gastric fundus muscularis propria were treated with ESD. The diameters of tumors were from 1.5 ～ 3.5 cm. Purse-string suture with single channel gastroscopy was performed for the gastric wall perforation during ESD. Results All patients underwent repair successfully. The procedure time was 10 ～ 15 min. No severe complications occurred. Conclusion Purse-string suture with single channel gastroscopy is a feasible and effective perforation repair method during ESD of gastric fundus.
