Association of hiatal hernia and gastroesophageal reflux: correlation between presence and size of hiatal hernia and 24-hour pH monitoring of the esophagus.

Abstract

Most patients in this study had normal results of pH monitoring of the esophagus regardless of the presence or absence of hiatal hernia. However, patients with larger hiatal hernias were more likely to have abnormal findings on pH monitoring; hiatal hernias of minimal size were a poorer predictor of the presence of abnormal gastroesophageal reflux.
