Esophageal Pressure Topography Criteria Indicative of Incomplete Bolus Clearance: A Study Using High-Resolution Impedance Manometry

Abstract

In individuals with normal EGJ relaxation and morphology, peristaltic contractions with breaks <2 cm in the 20 mm Hg isobaric contour or <3 cm in the 30 mm Hg isobaric contour are associated with complete bolus clearance, and longer breaks predict incomplete bolus clearance.
