Although it is commonly used in procedures such as endoscopic mucosal resection and endoscopic submucosal dissection, its use in double\u2010balloon enteroscopy\u2010assisted endoscopic retrograde cholangiopancreatography (DBE\u2010ERCP) has rarely been reported. An 81\u2010year\u2010old man with a history of distal gastrectomy and Roux\u2010en\u2010Y reconstruction underwent DBE\u2010ERCP for recurrent common bile duct stones. Despite 98 min of conventional attempts, the jejunojejunal anastomosis could not be identified because visualization was impaired by postoperative adhesions and residual food debris. After switching to the gel immersion method, the anastomosis was clearly identified within 4 min. Stone removal was successfully performed, and the postoperative course was uneventful. In this case, the gel immersion method markedly improved visualization and reduced intraluminal pressure, thereby facilitating identification of the anastomosis. This method may be particularly useful when conventional visualization is difficult during DBE\u2010ERCP, as it may enable rapid and safe identification of the jejunojejunal anastomosis.<\/jats:p>","DOI":"10.1002\/deo2.70348","type":"journal-article","created":{"date-parts":[[2026,5,11]],"date-time":"2026-05-11T04:15:08Z","timestamp":1778472908000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The
