What is Anorectal Manometry?
Anorectal manometry is a noninvasive procedure to evaluate the function of the rectal and anal muscles. This group of muscles, called the anorectal sphincter, controls how stool is released from your body. Anorectal manometry can help determine if these muscles are too loose, too tight or are not engaging at the right moment. This study measures the pressures created by the muscles, the sensation in the rectum (the passageway between the large intestine and the anus), and the neural reflexes necessary for normal bowel movements.
Why is There a Need To Perform Anorectal Manometry?
Having a bowel movement requires cooperation between specialized muscles and nerves in the rectum and anal canal. Normally, when stool enters the rectum, the anal sphincter muscles tighten to prevent passage of stool until you can get to a toilet. If these muscles are weak or do not contract in a timely way, fecal incontinence (leakage of stool) may occur. Similarly, when you push to have a bowel movement, the anal sphincter muscles relax to allow stool to exit. If they tighten instead, this could contribute to constipation.
What To Expect During the Study
Anorectal manometry is a fairly simple study and does not require anesthesia. The equipment to perform this study usually includes:
• A catheter with a balloon on the end that gets inserted into the anus and rectum.
• A syringe connected to the catheter allows a nurse to change the pressure in the balloon by inflating and deflating it, usually with air.
• Computer software is connected to the catheter and records data from the probe and balloon. • The study usually takes about 30 minutes.
