Sleeve gastrectomy (LSG) is technically simpler but may predispose patients to reflux, whereas Roux\u2010en\u2010Y gastric bypass (LRYGB) is recognized for its durable anti\u2010reflux effect. Robust prospective data comparing the procedures beyond 5\u00a0years are scarce. This study compared 8\u2010year persistent or new\u2010onset GERD after LSG versus LRYGB using multimodal assessment based on Lyon Consensus 2.0 criteria.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      In this prospective dual\u2010cohort extension of a previous trial (\n                      <jats:italic>n<\/jats:italic>\n                      \u00a0=\u00a075), 51 patients (LSG\u00a0=\u00a019; LRYGB\u00a0=\u00a032) completed 8\u2010year follow\u2010up. Multimodal assessment included a symptom questionnaire, upper endoscopy, contrast radiology, manometry, and 24\u2010h pH monitoring. The primary endpoint was conclusive GERD per Lyon 2.0 classification.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Conclusive GERD was present in 94.7% of LSG patients compared with 25.0% following LRYGB (RR\u00a0=\u00a03.8; 95% CI, 2.06\u20136.97). Erosive esophagitis (Los Angeles grade\u00a0\u2265\u00a0B) was more frequent after LSG (73.7% vs. 18.8%;\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0&lt;\u00a00.001).
