What Does an Anorectal Manometry Involve?
Before Anorectal Manometry
After the doctor explains the reasons and the steps of your procedure, you will be asked to take a cleansing bowel formulae (a laxative) at home the day before your procedure.
During the Procedure
Anorectal manometry can be performed in your doctor’s office, since it’s a very simple and painless procedure. The doctor will ask you to lay on your side, with your knees drawn toward your chest. Then, your doctor will insert in your anus a small catheter -the size of a thermometer- with a small balloon attached at the end. The balloon will be gradually inflated in order to detect the contractions and relaxations of the rectum and anal sphincter during the movements of squeezing and relaxing that your doctor will ask you to do. The catheter is connected to a machine that records all the results during the procedure for later interpretation. The entire procedure usually takes around 10-15 minutes.
After the Procedure
Usually, the procedure is performed on an outpatient basis and you can go home as soon as the procedure is finished. Also, you can resume your normal activities and diet immediately after the procedure.
Possible Risks and Complications
Anorectal manometry is a very safe procedure with almost no risk associated. You might feel some anal discomfort or irritation after the procedure or minor bleeding if you have any other anorectal conditions like hemorrhoids.
