Non-erosive and erosive gastroesophageal reflux diseases: No difference with regard to reflux pattern and motility abnormalities

Abstract

No difference was found between NERD and mild to moderate ERD in terms of acid exposure time and esophageal motor abnormalities. To a certain extent, ERD is a "more complicated" form of the disease. Host factors related to a particular patient (e.g. mucosal defense, genetics, acid clearance) might be responsible for the development of esophagitis.
