However, bariatric procedures, including a sleeve component, may cause post\u2010operative gastroesophageal reflux disease (GERD) due to disruption of the angle of His and increased intra\u2010gastric pressure. Sleeve\u2010plus procedures such as single\u2010anastomosis duodenojejunal bypass with sleeve gastrectomy (SADJB\u2010SG) can also cause non\u2010acid reflux related to bile and pancreatic juices. Consequently, acid\u2010suppressive therapy is often ineffective. We report a case of refractory GERD after SADJB\u2010SG, in which multichannel intra\u2010luminal impedance (MII)\u2013pH monitoring revealed predominant non\u2010acid reflux. The patient was successfully treated with conversion to resectional Roux\u2010en\u2010Y gastric bypass, which resulted in marked resolution of symptoms. This case highlights the importance of objective functional evaluation, including high\u2010resolution manometry and MII\u2010pH monitoring, to characterize reflux patterns, and to guide appropriate conversion surgery after sleeve\u2010plus procedures.<\/jats:p>","DOI":"10.1111\/ases.70340","type":"journal-article","created":{"date-parts":[[2026,7,1]],"date-time":"2026-07-01T02:43:32Z","timestamp":1782873812000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Conversion
