Abstract
INTRODUCTION: The one anastomosis gastric bypass (OAGB) is a widely diffused surgical procedure for morbid obesity. Several studies considered OAGB at risk for biliary reflux and anastomotic ulcers. The aim of the study was to evaluate gastro-esophageal reflux disease (GERD) and esophagitis/gastritis rate after OAGB diagnosed by upper endoscopy (UE), comparing the results with GERD-Health-Related Quality of Life (HRQL) score. METHODS: From July 2014 to February 2019, patients underwent OAGB with at least 12-month follow-up were retrospectively evaluated. Clinical evaluation was associated with GERD-HRQL scoring. UE with a mucosal biopsy was also performed. A comparison among clinical scores and endoscopic findings was performed. RESULTS: Two hundred forty-one patients were analyzed in the study. Anthropometric features (BMI, %Excess weight loss, %Total weight loss) were significantly improved. Only 30% of patients with GERD-HQRL>30 showed esophagitis at UE: 11/181 (6.1%) showed grade A erosive esophagitis, 2/181 (1.1%) grade B esophagitis, whereas no patient resulted in grade C/D. Fifty-two patients (28.7%) showed endoscopic remnant gastritis of at least grade 1, with histological gastritis of at least mild grade in 70/181 patients (38.7%). CONCLUSION: OAGB is a feasible and effective procedure in terms of weight reduction and comorbidities control, but controversies remain about the long-term onset of GERD and bile reflux. The incidence of esophagitis was increased after OAGB. However, the severity and incidence were lower compared to sleeve gastrectomy. Conversely, the incidence of gastritis, ileo-gastric anastomotic inflammation, and HP positivity were not negligible, suggesting the potential benefits of endoscopic surveillance after OAGB.
