To overcome difficulties in the removal of duodenal bulb lesions, especially those anatomically challenging locations, we developed endoscopic resection via antral submucosal tunneling (ERAST) technique. In this study, evaluated feasibility and safety ERAST for superficial subepithelial lesions bulb. This was a single-center retrospective study 10 patients with Submucosal from gastric antrum to duodenum performed facilitate en bloc tumor The rate, postoperative bleeding, perforation were primary endpoints. Ten (four six subepithelial), an average size 19.1 ± 9.2 mm, resected by ERAST. Esophagogastroduodenoscopy follow-up after 2 months indicated complete wound healing all patients. our experience, found be feasible safe technique bulb, that are difficult access.
