ObjectiveTo investigate the efficacy and application value of endoscopic submucosal dissection(ESD) for treating gastric fundus submucosal tumors. MethodsThe clinical data of 29 patients with gastric fundus submucosal tumors treated by ESD were retrospectively analyzed, and the efficacy was evaluated. ResultsOf the 29 patients undergoing ESD, 2 cases had intraoperative slightly heavy bleeding, with the maximum bleeding volume of about 20mL, 4 cases suffered from intraoperative perforation. Twenty-nine cases of gastric fundus submucosal lesions were completely dissected, and no postoperative complications occurred, such as delayed bleeding and perforation. Operation duration and postoperative hospital stay were 70.1±29.3 minutes and 5.3±1.2 days, respectively. Twenty-five cases were diagnosed as gastrointestinal stromal tumor and 4 as leiomyoma confirmed by postoperative pathological findings. All patients were followed up for 4 weeks, no special complications occurred, and 3 months later, a rechecking based on gastroscopy exhibited favorable wound healing and no relapse cases. ConclusionESD is a safe and effective therapy for gastric funds submucosal tumors, with a low incidence rate of postoperative complications and perfect recovery.
