Colorectal physiology testing
TESTS TO INVESTIGATE LOWER BOWEL PROBLEMS
We're able to carry out a wide range of colorectal physiological tests to get to the root of your lower bowel problems
What are colorectal physiology tests?
If you're having problems with your back passage or lower bowel, we can carry out tests to get to the root of your problems. These may include:
- Colonic transit: This measures how long it takes for you to empty your bowel. We'll ask you to swallow a capsule and track it on an X-ray
- Rectal sensation: This involves inserting a balloon into your rectum to see how much volume it can hold
- Anal pressure measurements: This involves inserting a small tube into your back passage to measure the strength of your rectum muscles
- Pudendal nerve function test: This test studies the function of the nerves in your pelvic floor
- Ultrasound: This scan can tell if the muscles around your back passage are intact or damaged
- Evacuation proctography: This test is used to investigate any problems you may have when you try for a bowel movement
Depending on your symptoms, we may carry out one or a combination of these tests.
Need to know
You'll most likely be able to go home on the day of your test(s). You can arrange for a friend or relative to come and pick you up after the test. However, we won't be giving you a sedative beforehand (a drug to help you sleep) so you won't necessarily need someone to come and collect you.
You may experience a little discomfort in the lower part of your tummy or back passage after the tests for a few hours but this usually settles down. If you experience any unusual symptoms, like bleeding, please do get in touch.
