Dose-related healing of artificial ulcers after endoscopic submucosal dissection using esomeprazole: A randomized controlled study

AbstractBackground:Endoscopic submucosal dissection (ESD) is a standard procedure for treating gastric neoplasms. However, ESD causes larger artificial ulcers other than mucosal resection methods. We conducted this prospective randomized controlled study to evaluate the effect of stronger acid suppr
