Comparison of Esophageal Acid Exposure Distribution Along the Esophagus Among the Different Gastroesophageal Reflux Disease (GERD) Groups

Abstract

ALL GERD groups demonstrated significant greater esophageal acid exposure at the very distal portion of the esophagus, primarily as a result of short upright reflux events. Unlike erosive esophagitis and BE, NERD patients demonstrate a more homogenous acid distribution along the esophagus.
