Anorectal Manometry

What is Anorectal Manometry?

Anorectal manometry is a test used to assess how well the rectum and anal sphincter are working. These two components work together to control the passing of stool. This test is used for patients who have difficulty passing stool (constipation) or fecal incontinence (leakage of stool). A small flexible tube with a balloon on the end is inserted into the rectum. The balloon is gradually inflated to mimic a bowel movement. A small computer records the pressure exerted on the small tube and this allows your doctor to better determine the cause of your symptoms. 

What is the preparation for Anorectal Manometry?

You may need to prep your body ahead of time. This prep is necessary so that there is no stool in the rectum. Before the test you should not eat or drink anything after midnight the night before the test. You may need to do an enema 2-3 hours before your appointment. This can be purchased over the counter.
