ObjectiveTo explore the clinical value of endoscopic full-thickness resection (EFTR) in the treatment of gastric tumor originating from muscularis propria. MethodsTwenty-eight patients with gastric tumors originating from muscularis propria were confirmed by endoscopy, miniprobe endoscopic ultrasonography and abdominal CT scan. All the patients underwent EFTR. ResultsThe gastric tumors originating from muscularis propria of 28 patients were completely removed by EFTR, and the wound surface was closed by purse string suture using nylon rope and titanium clips.No conversion to surgery occurred. The lesions located at gastric fundus and gastric body were found in 25 cases and 3 cases respectively. The diameters of tumors were 0.8-4.0 cm. Twenty-four cases and 4 case were confirmed as astrointestinal stromal tumor and liomyoma by postoperative pathology respectively. The patients were followed-up for six months. The surgical wound surface healed, and no tumor recurrence occurred. ConclusionEFTR obtains a definite efficacy for gastric tumor originated from muscularis propria, and is a minimally invasive, safe and effective treatment.
