Anorectal Manometry

A Simple Test of How Well the Rectal and Anal Muscles Work

What Is Anorectal Manometry?

Anorectal manometry is a simple, safe test that measures how well the muscles and nerves in your rectum and anus are working. A thin, flexible tube with a small balloon on the tip is gently placed in the rectum, and sensors measure muscle pressure, coordination, and sensation as you squeeze, relax, and bear down.

 

The test helps your doctor understand the cause of problems like chronic constipation or difficulty controlling bowel movements. It is performed in the office, takes about 30 minutes, and does not require sedation, so you can return to your normal activities right away.

Why Anorectal Manometry Is Performed

Many bowel problems are caused by muscles and nerves that are not working together the way they should. Anorectal manometry gives your doctor precise information about how your pelvic floor and sphincter muscles function, which blood tests and imaging cannot show. This helps pinpoint the true cause of symptoms and guide the most effective treatment, including biofeedback therapy.
