Cross-sectional study on bile acid reflux and Barrett's esophagus, Gastro Esophageal Reflux Disease - Bile Acid Reflux and Barrett's Esophagus, GERD

Patients with Barrett's esophagus have higher total bile acid concentration (total BA) and certain bile acid fraction concentrations (e.g. Conj CDCA). The Spearman rank correlation coefficient between total BA and Conj CDCA is strongly correlated at 0.95. Total BA, Conj CA, and Conj CDCA are strongly correlated with the color of gastric juice. The color of the intragastric liquid was quantified to obtain a cutoff value (Youden Index) for the presence of Barrett's esophagus (YI 11.3).
