BACKGROUND: Although bile reflux plays an important role in the development of Barrett's esophagus, the relationship between endoscopic findings of bile reflux and Barrett's esophagus remains unclear.
OBJECTIVE: This study evaluated whether endoscopic evidence of bile reflux was associated with the presence of Barrett's esophagus.
METHODS: A retrospective analysis of a prospectively maintained database comprising consecutive patients who underwent screening esophagogastroduodenoscopy was conducted. Endoscopic evidence of bile reflux was defined as the presence of bile-stained fluid in the gastric fundus. We performed multivariate analysis to identify predictive factors that differed significantly between patients with and without Barrett's esophagus.
RESULTS: Of 4021 patients, 922 (23%) had Barrett's esophagus, and 1000 (25%) showed endoscopic findings of bile reflux. Multivariate analysis revealed endoscopic evidence of bile reflux as the strongest independent factor associated with the presence of Barrett's esophagus (odds ratio [OR] 5.65, 95% confidence interval [CI] 4.71-6.76) in relation to the presence of hiatal hernia (OR 3.30, 95% CI 2.70-4.04) and male gender (OR 1.54, 95% CI 1.24-1.91).
CONCLUSIONS: Endoscopic evidence of bile reflux was independently associated with the presence of Barrett's esophagus. This finding might help identify patients at future risk of Barrett's esophagus who could benefit from increased endoscopy surveillance.
