Resting pressures in the lower esophageal sphincter

Abstract

Interdeglutive pressures of the lower esophageal sphincter (LES) were studied by nonpullthrough techniques in 36 volunteers. Resting pressures did not remain at the high levels observed when the LES was entered. In 30 studies a gradual protracted decay ranging from 5 to 18 mm Hg was observed. These studies suggest that the LES may not pose a continuous barrier to reflux of gastric contents.
