Do obesity and diabetes increase the frequency and risk of bile reflux gastritis post-cholecystectomy?

<br><b>Introduction:</b> Biliary gastropathy is a disease characterized by upper abdominal pain, frequent heartburn, nausea, and vomiting of bile. It is caused by the backward flow of duodenal fluid into the stomach and esophagus.</br> <br><b>Aim:</b> A retrospective cohort study was performed to estimate the prevalence and risk factors of bile reflux gastritis secondary to cholecystectomy and to evaluate the endoscopic and histopathologic changes in gastric mucosa caused by bile reflux gastritis.</br> <br><b>Materials and methods:</b> The study involved 64 patients with epigastric pain and/or dyspeptic symptoms during the period from January 2018 to December 2020 who presented to Zagazig University Hospitals. The subjects were divided into two groups: the control group (CG), with 30 subjects who had never undergone any biliary interventions, and the post-cholecystectomy group (PCG), consisting of 34 patients who had undergone cholecystectomy.</br> <br><b>Results:</b> The prevalence of bile reflux gastritis was 16.7% in the CG and 61.8% in the PCG. In both groups, diabetes, obesity, increased gastric bilirubin, and increased gastric pH were risk factors for bile reflux gastritis (r = 0.28, 0.48, 0.78, and 0.57, respectively). However, there were no correlations between age, sex, epigastric pain, heartburn, vomiting, and the presence of bile reflux gastritis.</br> <br><b>Discussion:</b> Bile reflux gastritis is a common complication following cholecystectomy and is more common among obese and diabetic patients.</br>.
