Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of air-coupled balloon esophageal and anorectal manometry catheters with solid-state esophageal manometry and water-perfused anorectal manometry catheters.
Clinical gastrointestinal manometry studies are currently performed with multilumen water-perfused polyvinyl or strain gauge sensor solid-state catheters. A disposable catheter incorporating air-filled balloons has been developed with performance characteristics suitable for esophageal and anorectal manometry studies. ⋯ Correlation coefficient analysis demonstrated that LES pressures, esophageal contraction amplitudes, and anorectal resting and squeeze pressures were not significantly among between the different catheters. We conclude that recently developed air-filled balloon esophageal and anorectal manometry catheters provide very similar measurements of LES, esophageal body, and anorectal sphincter pressures compared to presently used manometry catheters.
