Pelvic Floor

The exact tests used will depend on the type of pelvic floor abnormality and whether other organs are affected as well as the bowel:

endoanal USS

specialised test used in assessing whether the two anal sphincter (‘back passage’) muscles are intact or not (in patients affected by faecal incontinence)

MRI proctogram

a dynamic (ie study showing movement) assessment of how the pelvic organs function during defaecation

defaecating proctogram

a type of dynamic X ray test (test showing movement) used to investigate patients who have significant problems evacuating

ano-rectal manometry

an investigation that determines the strength of the anal sphincter (‘back passage’) muscles both when at rest and when trying to squeeze to delay defaecation

pudendal nerve function

a test that measures the speed ie function of the main nerve that helps provide bowel control

flexible sigmoidoscopy

limited endoscopic (‘camera’) investigation of the lower part of the bowel
