Normal values of esophageal pressure responses to a rapid drink challenge test in healthy subjects: results of a multicenter study

Abstract

The range of normal pressure responses to a rapid drink challenge test in health has been established in a large multicenter study. Main responses are a virtually complete inhibition of esophageal pressures with a low-pressure gradient across esophagogastric junction. This data would allow the correct differentiation between normal and disease when using this test.
