Abstract

The purpose of this study was to evaluate the interindividual and intraindividual variability of slow motorized pull-through lower esophageal sphincter (LES) manometry compared to standard station pull-through LES manometry to measure LES overall length, abdominal length, and pressure and to report normal values for the slow motorized pull-through method. The slow motorized pull-through had significantly smaller coefficient of variation, indicating closer agreement between different examiners in analyzing a given tracing. The correlation coefficients for each parameter in normal subjects and symptomatic patients was significantly higher when using slow motorized pull-through for both patients and normal subjects for all three parameters. The 5th percentile of normal values obtained from 41 volunteers for LES overall length, abdominal length, and pressure was 2.7 cm, 1.4 cm, 5.1 mm Hg, respectively. The results indicate that the slow motorized pull-through method is more reproducible than the standard station pull-through method both between different observers and when the same examiner measures the same tracing on two different occasions.
