Abstract

Background: Gastroesophageal reflux disease (GERD) is common after sleeve gastrectomy (SG). We aimed to evaluate the effect of revisional one anastomosis gastric bypass (OAGB) on GERD, compared with revisional Roux-en-Y gastric bypass (RYGB) Methods: A retrospective single-center study of a prospectively maintained patient registry (2018–2022). All patients with GERD undergoing OAGB and RYGB after SG were retrieved and included in the study. Results: Seventy-eight SG patients had conversion to OAGB (n=31) and RYGB (n=47). Baseline characteristics were similar except age (43.8±11.5 vs. 50.3±13.4 years; p=0.03), body mass index (39.9±8.8 vs. 30.6±6 kg/m2; p<0.001), time interval (8±2.7 vs. 6.4±3.4 years; p=0.01), and sleep apnea (29% vs 8.5%; p=0.01), respectively. There was no significant difference between groups in number of patients consuming proton pump inhibitors (70.1% vs. 72.3%; p=0.66), GERD-health-related quality of life (HRQL) score (9.6±7.2 vs. 13.1±8; p=0.06), and pathological endoscopic findings (48.4% vs. 46.8%; p=0.89). Major complication rates were 0% vs. 8.5% (p=0.09). At 32.4 months follow-up, total weight loss was 22%±12.9 and 4.4%±14.6 (p<0.001), GERD resolution 77.4% and 91.9% (p=0.03), HRQL scoring improved to 1.7±4.5 and 1.7±2.7; p=0.94 for OAGB and RYGB, respectively. Conclusions: SG conversion to RYGB provides better chances for definitive treatment of GERD. OAGB results in good symptom resolution and improved quality of life and may be considered for post-SG GERD treatment. The most appropriate solution should be individualized to each patient.
