Anorectal Manometry

Anorectal manometry studies are conducted on patients who experience bowel symptoms such as difficulty emptying the bowel, fecal incontinence (leakage of stool), fecal urgency, constipation, and other fecal problems.

This study evaluates the rectal and anal muscles to determine how strong they are and if they are working synergistically. This information will better inform your doctor on which treatment options are right for you.
This procedure can take anywhere from 30-60 minutes.

How to prep for the study:

  • Do not eat or drink anything starting two hours before the start of the study
  • Please defecate prior to the study, if possible
  • If you have a history of constipation, please discuss with your provider if you should use a fleet enema prior to the study.
  • You may take your regular medications up to two hours before the procedure with small sips of water.
  • Please check in at least 15 minutes prior to your procedure time.

How Is the Test Performed?

  1. You will be asked to change, waist down and put on a drape and lie down on your left side with your knees slightly bent. Please note that because of the sensitive nature of this test, every effort will be made to respect and guard your privacy.
  2. A small catheter with a balloon attached to the end will be placed about four inches into your rectum. The catheter may be slowly pulled out and placed back in during the exam.
  3. You will be asked to do a series of squeezes, like holding in a bowel movement, followed by bear downs, like pushing out a bowel movement.
  4. The balloon at the end of the catheter will then be inflated and deflated a few times. We will ask when you feel a sensation in your rectum or when you feel the urge to have a bowel movement.
  5. We will then take out the catheter, and reinsert. The balloon will be inflated with air, and you will be asked to try and expel (push out) the balloon within 5 minutes. If you are unable to do so, we will deflate the balloon and take the catheter out for you.


What happens after the study?

You will be scheduled for a follow-up appointment to discuss the results of the study.
You may expect to feel some discomfort in your rectum following the procedure. This should pass in a couple of hours. If it does not, you should follow-up with our office.
