High Resolution Esophageal Pressure Topography (HREPT) in Asymptomatic Volunteers. A Comparative Study Between Solid-state and Water-perfused Systems

Background and Aim: a) HREPT is the most accurate technique for identifying esophageal motility disorders (EMD). Results: Twenty HV were included, 14 women, mean age 34 (24-55) years. The pressures in the UES and LES pressures, IRP are lower with the perfusion system (p 0.0064, 0.008 and 0.0061, respectively) and have a faster peristalsis registration with the solid system, (DL p 0.0002). With the CC 2012, the solid state system presented a higher frequency of volunteers with hypotensive peristalsis (p 0.0143).
