Used to diagnose bowel incontinence and constipation, anorectal manometry measures proper bowel functioning.
Anorectal manometry is an in-office exam that tests the rectum’s ability to contract. A tiny tube with a balloon on the end is inserted into the rectum. The balloon helps to measure the function of the sphincter muscles. A machine will measure the pressure of your movements during anorectal manometry. The procedure takes about 30 minutes.
Preparation is needed for this test, but your physician will go over everything with you if he or she determines this is the proper diagnostic tool for your bowel symptoms. It is an outpatient procedure, meaning no hospital stay is needed.
