Postoperative Clinical-Endoscopic Follow-up for GERD and Gastritis After One Anastomosis Gastric Bypass for Morbid Obesity: How, When, and Why.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
introductionThe 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.
methodsFrom 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.
resultsTwo 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%).
conclusionOAGB 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.
