Anorectal Manometry

What is anorectal manometry?

Dr. Rayapudi performs an anorectal manometry procedure to identify potential problems associated with the anal sphincter muscles and nerves that help you pass stool.

During this test, several measurements are taken, including:

  • Sensation in your rectum
  • Anal sphincter muscle pressure
  • Neural reflexes that control bowel movements

Dr. Rayapudi might suggest an anorectal manometry if you’re suffering from involuntary fecal leakage (incontinence) or chronic constipation.

Why is anorectal manometry done?

An anorectal manometry provides valuable insight into the specialized muscles that control normal bowel movements.

In a healthy rectum, your anal sphincter tightens to prevent a bowel movement from occurring until it’s convenient. When you push during a bowel movement, this relaxes your anal sphincter muscle which allows stool to pass freely. If your anal sphincter weakens or fails to contract appropriately, you can experience involuntary bowel leakage or constipation.

By performing an anorectal manometry, Dr. Rayapudi can determine the strength of your anal sphincter muscles and if they’re relaxing and tightening when appropriate.

What can I expect during anorectal manometry?

Your anorectal manometry typically takes 20-30 minutes. Before your test, Dr. Rayapudi might recommend having one or two enemas to clear your bowels completely.

During your appointment, Dr. Rayapudi has you lie on your side so he can perform your test. While you relax comfortably, he inserts a thin, flexible catheter with a balloon into your rectum.

To conduct the test, Dr. Rayapudi inflates the balloon to measure pressure. You’re asked to tighten your sphincter muscles as though you’re trying to prevent a bowel movement and also to bear down as though you’re trying to pass stool.

Following your anorectal manometry, you can resume regular activities.

Can an anorectal manometry treat fecal incontinence and constipation?

While an anorectal manometry test is not a treatment, the details that it provides can help determine what kind of therapies may work best for your particular situation.

Based on your results, Dr. Rayapudi might recommend several treatments for weak anal sphincter muscles and reduced rectal sensation, like biofeedback techniques and exercises to strengthen the pelvic floor muscles.

Or if you’re experiencing constipation problems due to abnormal muscle function, Dr. Rayapudi might suggest retraining the muscles to relax through biofeedback techniques.
