Anorectal Manometry at Drexel Gastroenterology

Anorectal manometry is a safe, low-risk procedure that is used to evaluate patients with fecal incontinence or chronic constipation. The test measures how strong the sphincter muscles are and whether they relax as they should during stool passage. There are many causes of fecal incontinence and chronic constipation, and anorectal manometry provides helpful information in treating these patients.

During anorectal manometry a catheter (a small, flexible tube) is inserted into the rectum and the patient is asked to squeeze, relax, and push at various times. This allows the technician to measure the pressure of the anal sphincter muscles, the sensation in the rectum, and the neural reflexes that are needed for normal bowel movements. Anorectal manometry takes approximately 30 minutes and does not require sedation or pain medication.
