Anorectal manometry is an important diagnostic tool used in the assessment of faecal incontinence and chronic constipation. It is a test that measures how well the rectum and anal sphincters work together to eliminate stool (faeces). The anal sphincter has an internal and external sphincter, or valve, which helps to control continence (passing) of stool. These valves are made of muscles that control the opening and closing of the anus. The test is performed to see how well it is working.
Colonic transit marker studies
The colon transit study is a motility (movement) study of your colon.
The purpose of this study is to check if the movement of faeces (stool) through your colon is normal or slow and assess the function of your bowel. This will help your doctor to decide on appropriate treatment for your constipation.
Dynamic MRI defecography
MRI Defaecography is an imaging exam that doctors use to look at problems in the structure of the pelvic floor or problems with how these muscles are working when you move your bowels. In addition to MRI images of the pelvic floor, rectum and sphincter, images are taken during squeezing, straining and defaecation. It is an important test to investigate for the cause of chronic constipation.
