Y Not Roux-en-Y?: Resolution of Barrett's Esophagus After Surgical Conversion of Gastric Sleeve in Two Patients.

Esophageal lesions ranging from erosive esophagitis to Barrett's esophagus (BE) eventually develop months-years after sleeve gastrectomy (SG), representing a significant post-surgical issue in GI practice. Roux-en-Y gastric bypass (RYGB) conversion is a widespread and effective method of managing reflux and esophageal complications following SG. Although some studies using a limited sample size have demonstrated that RYGB performed as a primary procedure may regress BE presumably by reducing reflux, whether the same may apply to RYGB performed as revision surgery after SG has scarcely been addressed in the literature. Though histological regression of BE following primary RYGB occurs in 51.9% of patients, with regression of Barrett's dysplasia in 50% of cases, revisional RYGB yields a remission rate as high as 81.8% for Barrett's metaplasia and 100% for dysplastic lesions, although the number of subjects in the published studies are very small. We report two patients who developed GERD and BE following SG with complete regression 12 months after conversion to RYGB in both subjects, confirming the substantially greater proportion of BE resolution in patients undergoing RYGB as revision surgery following SG.
