Anorectal Manometry

Anorectal manometry is a test to evaluate the functioning of the anal canal, usually to diagnose the cause of chronic constipation or fecal incontinence. The test can be helpful to confirm the cause of fecal incontinence when it is suspected that surgery or disease has injured the nerves or muscles in the anus, or when diabetes may have resulted in impaired sensation in the rectum. In addition, anorectal manometry may also be used as a treatment for fecal incontinence to retrain anal muscles to contract more forcefully. A laxative or an enema may be required before an anorectal manometry procedure.
