  3. Anorectal Manometry & Physiology...

Anorectal Manometry is a test to investigate the function of the ano-rectum, more specifically the pressure the muscles of the anal canal, rectum and pelvic floor can generate, and the coordinated (or discoordinated) movements of these muscles during a squeeze, push and relaxation. It is combined with a simple and painless rectal sensation test to gain more information of the physiological functioning of these organs.

Anorectal manometry and physiology testing is very important in the assessment of anal sphincter muscle incompetence, fecal incontinence, anismus, obstructed defecation, chronic anal and rectal pain and other functional disorders of the ano-rectum.

What to expect when going for this procedure?

The test needs no preparation, but it is better if you could go to the toilet in the morning before this test is performed. It takes about 10-15 minutes, not at all painful, no sedation needed.

You will not receive the final result of the test straight after the procedure, but you will be able to look at the graph on the screen and get your doctors comment on its normality. Your doctor needs to analyse the graphs to give you a precise description and diagnosis, which then guides the treatment plan. This report with the explanation you will receive at your free follow-up a minimum of 1 day after your procedure.
