We reported a case of a 70-year-old male with gastroscopy showed an elevated lesion with central depression on the gastric body, with clear margins. Background consistent with bile reflux gastritis. Endoscopic submucosal dissection (ESD) was performed. Histopathology confirmed a gastric serrated adenoma. This study reports the first documented case of gastric serrated adenoma arising in a background of bile reflux gastritis, suggesting bile reflux may be a potential risk factor for gastric serrated adenoma development.<\/jats:p>","DOI":"10.3389\/fonc.2025.1670442","type":"journal-article","created":{"date-parts":[[2025,10,6]],"date-time":"2025-10-06T04:10:40Z","timestamp":1759723840000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["A
