Effect of hiatal hernia on proximal oesophageal acid clearance in gastro‐oesophageal reflux disease patients

Abstract

The presence of hiatal hernia is a strong predictor of more prolonged proximal oesophageal acid exposure and clearance. Hiatal hernia is likely to play a role in the pathophysiology of gastro-oesophageal reflux disease symptoms, and should be taken into greater consideration in the treatment strategies of the disease.
