Anorectal manometry measures the functional performance of the anus and rectum. Our physicians will use a small catheter and a balloon with sensors that measures the pressures of the anal sphincter muscles, the sensation in the rectum and the neural reflexes that are needed for normal bowel movements.
Our physicians generally recommend this test to evaluate patients with generalized bowel dysfunction to include chronic constipation or fecal incontinence.
After changing into a hospital gown, you will lie on your left side on an exam table. A small, flexible catheter with pressure sensors and a balloon on the end will be gently inserted into the rectum. During the test, we will inflate the balloon to assess the normal reflex pathways. The nurses may also ask you to squeeze, relax and push at various times to measure the anal sphincter muscles. Anorectal manometry generally does not cause any pain and takes approximately 30 minutes.
Our office will give you detailed instructions prior to the test. However, you will be asked to administer an enema at home the day of the test — our nurses will instruct you the amount and type to be used. Please do not eat anything two hours prior to the test.
You will be able to drive yourself home and resume normal daily activity following the test. You may receive results the day of your test or your physician may require a few days to review the results.
