Su1347 ANNUAL ENDOSCOPY IS ENOUGH FOR GASTRIC CANCER SURVEILANCE SCHEDULE AFTER THE ENDOSCOPIC RESECTION

Aims Patients who received endoscopic resection for early gastric cancer (EGC) or high grade dysplasia (HGD) are at high risk of subsequent development of metachronous gastric cancer. The aim of this study is to compare the prognosis of patients between biannual and annual endoscopic surveillance in patients after endoscopic resection of EGC or HGD.
