Characteristics of gastro-esophageal reflux episodes in Barrett’s esophagus, erosive esophagitis and healthy volunteers

Abstract

Barrett esophagus patients have more severe reflux as shown by the number of acid and weakly acidic reflux episodes, re-reflux episodes and proximal migration. Given that PPI change only the pH of the refluxate, the role of weakly acidic reflux in Barrett's patients on acid suppressive therapy warrants further investigation.
