Prevalence and axial length of hiatus hernia in patients, with nonerosive reflux disease: a prospective study.

Background And Aims: The relationship between hiatus hernia and reflux esophagitis is well established. However, there are conflicting reports regarding its effect on the development of nonerosive reflux disease (NERD). Our aim was to investigate the prevalence and axial length of hiatus hernia in patients with NERD, compared with patients with reflux esophagitis, Barrett esophagus, and controls.
