To evaluate the value of forward-return way in endoscopic resection for the treatment of gastric fundus stromal tumor, patients with gastric fundus stromal tumor in muscularis propria diagnosed by endoscopy and endoscopic ultrasonography at the Department of Digestive Endoscopy of the Fourth Affiliated Hospital of China Medical University from June 2020 to June 2021 were prospectively enrolled in the study. All patients were treated with endoscopic full-thickness resection under general anesthesia with endotracheal intubation. The success of forward-return way, endoscopic procedure, operation performance, pathological classifications and complications were analyzed. A total of 12 patients were enrolled. All of them were confirmed as having stromal tumor by postoperative pathology, with 10 of very low risk and 2 of low risk. Forward-return way was successful in 9 patients and failed in 3 patients. Nine patients were successfully treated with endoscopic procedure eventually. No intraoperative bleeding occurred in any patient. In endoscopic resection, the scores of same direction of forward and backward, endoscopic field of view, and endoscopic body stability were all 2.00 points. Forward-return way has clinical application value for the endoscopic treatment of gastric fundus stromal tumor.
