Interaction of hiatus hernia size and LES pressure on reflux
Interaction of hiatus hernia size and LES pressure on reflux
Model showing the relationship between hiatus hernia size, lower esophageal sphincter (LES) pressure, and reflux score. The reflux score increased with increasing hernia size and lower LES pressure, both of which were required for marked reflux.
