Acid and bile reflux in erosive reflux disease, non-erosive reflux disease and Barrett's esophagus.

Abstract

The Bilitec method reliably identifies the presence of bilirubin and quantitatively detects duodenogastroesophageal reflux of bile. Mixed reflux (acid and bile) is the chief pattern of reflux in GERD patients in this study. Bile reflux either alone or mixed with acid reflux contributes to the severity of erosive and non-erosive reflux disease as well as to Barrett's esophagus.
