In this study, we evaluated the feasibility and safety of ERAST for the removal of superficial and subepithelial lesions in the duodenal bulb. This was a single\u2010center retrospective study of 10 patients with lesions in the bulb. Submucosal tunneling from the gastric antrum to the duodenum was performed to facilitate en bloc tumor resection in the bulb. The en bloc resection rate, postoperative bleeding, and perforation were the primary endpoints. Ten lesions (four superficial and six subepithelial), with an average size of 19.1\u2009\u00b1\u20099.2\u2009mm, were resected en bloc by ERAST. Esophagogastroduodenoscopy follow\u2010up after 2\u2009months indicated complete wound healing in all patients. In our primary experience, ERAST was found to be a feasible and safe endoscopic resection technique for the removal of lesions in the duodenal bulb, especially those that are difficult to access.<\/jats:p>","DOI":"10.1111\/den.14350","type":"journal-article","created":{"date-parts":[[2022,5,15]],"date-time":"2022-05-15T14:10:36Z","timestamp":1652623836000},"page":"1063-1068","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Endoscopic
