Anorectal Manometry Testing

Manometry testing is a procedure that measures the force and coordination of smooth muscles within the body. There are two types of manometry testing: esophageal and anorectal. Anorectal manometry measures the strength of the rectal and anal muscles needed for normal bowel movements. It is used to determine problems with severe constipation or fecal incontinence. 


Anorectal Manometry Testing Complications

Anorectal manometry is a safe and low-risk procedure.  You may feel some slight discomfort during the test, but it is unlikely to cause any pain. 


Preparing for Anorectal Manometry Testing

Preparing for anorectal testing requires you to not ear or drink at least 2 hours before the procedure. You will give yourself 2 Fleet® enemas 2 hours prior to the test.

The day of the procedure:

Fleet Enema – Take the fleet enema 2 hour before coming for exam. 

  • Insert the enema liquid into the rectum and hold it in for up to 10 minutes before releasing the fluids.  
  • Take your usual blood pressure medications with a small sip of water at least 2 hours prior to study. 
  • You should not eat anything during the 2 hours prior to the procedure.
  • If you are diabetic, do not take any of your oral medications or aspart. Please take 50% of your normal glargine dose. Please consult your diabetes provider for individualized instructions or if you are a Type 1 Diabetic. 
  • Please check in at least 45 minutes prior to your procedure time. 

What to Expect

What to Expect During Testing

The tests take approximately 45 to 60 minutes. You will be asked to change into a hospital gown. A technician or nurse will explain the procedure to you, take a brief health history, and answer any questions you may have.

During the Test

During the Test

  • Prior to the procedure, you will need to make sure your digestive tract is empty.  You doctor will give you instructions. 
  • You will lie on your left side. A small tube, about the size of a thermometer, with a deflated balloon at the end is inserted into the rectum.  
  • The catheter is connected to a machine that measures the pressure. During the test, the small balloon attached to the catheter may be inflated in the rectum to assess the normal reflex pathways.  
  • The nurse or technician may also ask the person to squeeze, relax, and push at various times. Another test may be done to measure the time it takes to expel a balloon from the rectum.
