Anorectal manometry

Anorectal manometry

Anorectal manometry is a test to measure how well the rectum and anal sphincter are working. This test is commonly performed for people who have fecal incontinence and constipation to check how sensitive the rectum is and how well it is working. The test also checks the strength of the muscles of the anus. These muscles control the opening and closing of the anus.

How is it performed?

 

  • The night before the test, the patient will be instructed not to eat or drink anything and may be given a laxative.
  • During the procedure, the patient will be made to lie on their side.
  • A flexible tube is inserted into the anus of the patient, passing a ring of muscles called the anal sphincter, before passing into the rectum.
  • Once the tube is in place, a small balloon at the tip of the tube is gradually inflated. This causes the nerves and muscles in the rectum and anus to begin to squeeze.
  • The end of the tube outside the anus is connected to a machine that records the contractions and relaxations of the rectum and anal sphincter.
  • After the measurements are taken, the tube is slowly withdrawn.
  • The test typically takes 10 to 20 minutes to complete.
