High-resolution Anorectal Manometry Measures Are More Accurate Than Conventional Measures in Detecting Anal Hypocontractility in Women With Fecal Incontinence.
Anorectal manometry is a common test of anal tone and contractility. However, existing measures are often criticized for their poor ability to detect functional differences between individuals with presumably normal sphincter function and individuals with fecal incontinence. We investigated whether new measures, derived from high-resolution anal manometry (HR-ARM), more accurately identify incontinent women with abnormal sphincter function than measures from conventional anal manometry (C-ARM).
