An Anorectal Manometry is a study done to evaluate the motor function and coordination of the anal and rectal muscles, which work together with the brain to control our bowel movements. 

 

It’s a test indicated for certain patients with constipation or those with fecal incontinence.

 

Two hours before the procedure, you will need to avoid any food or drink, and you will require to take 2 enemas in order to partially clean the distal part for your colon.

 

The procedure consists on the placement of a small lubricated catheter with a balloon attached to the end that will be placed about four inches into your rectum. You will be asked to do a series of squeezes, like holding in a bowel movement, followed by pushes similar to pushing out a bowel movement. The balloon at the end of the catheter will then be inflated and deflated a few times to evaluate if you feel a sensation in your rectum, as well as, the time you feel the urge to have a bowel movement.

 

Later, you might be asked to sit on a commode to test if you can expel (push out) the balloon within 5 minutes. If you are unable to expel the balloon, then the nurse will deflate it and remove it.

 

The entire procedure typically takes 30-60 minutes, and your privacy will be respected throughout.
