Characterization and correction of pressure drift in the ManoScan^™ high‐resolution manometry system: <i>In vitro</i> and <i>in vivo</i>

Abstract

The substantial drift in the ManoScan(™) HRM system is highly variable and not corrected via the standard operating instructions. ITC has superior performance but requires communication with the manufacturer to enable this option. This has a substantial impact on clinical diagnosis, utility of existing normative data, and future research of HRM.
