Gastrointestinal Physiology Service

This information will explain your forthcoming tests to help you avoid unnecessary concern. There is no need to prepare the bowel for the tests and you will be able to proceed to your normal activities afterwards. Before commencing with any of the function tests a medical history is taken. This will include specific questions on your bowel complaint, any medication that you may be taking, surgery that you may have had and, where applicable, your child bearing history.

After the history has been taken the tests will be explained to you. The tests look at the way in which the muscles and nerves around the anal canal are working together. Some very small catheters are introduced into the anal canal to take the measurements. Once the function tests and any other investigations have been completed you may need to come back to the clinic to see a Doctor to discuss your results.

How long will it take? The session usually takes about half an hour but the tests will take less than half of this time.

Why do I need the physiology function tests? This service, only available in some specialist colorectal units, provides you and your Doctor with information on the function of the lower end of the bowel. Together with tests such as an ultrasound or an X-ray, which show the anatomy of this region, these tests give the information necessary to select the best treatment or therapy for your complaint.

Is it painful? No, it is not painful although a slight discomfort may be felt if you are already sore in the anal region. It is very important that you relax as much as possible, not only for yourself but also for the person conducting the investigation.

Can the tests be performed during menstruation? Yes, this will not affect the tests in any way.

Confidentiality: As with any medical report all information obtained from the function tests is strictly confidential.

Description of the Biofeedback Service

A few specialist centres offer biofeedback therapy (bowel and muscle retraining). This treatment usually involves an initial assessment by a specialist nurse or physiotherapist who will obtain a detailed assessment of your bowel symptoms, general health, diet, lifestyle, and any other factors that may influence your bowel function.

From this assessment and the results of any other investigations you may have had, the therapist will discuss with you the likely cause of your problems and set an individualised treatment programme with strategies for you to follow.

Most patients have further appointments at regular intervals. It usually takes several months for improvement to occur and this improvement often continues following completion of therapy. You will have to work hard to make this therapy effective. However, the majority of people find this therapy improves their bowel function.

Biofeedback Treatment

Before the first appointment patients are posted a symptom questionnaire and a bowel diary to complete and bring into hospital. Initially each patient will have an assessment interview.

Patient Leaflets

These leaflet will give you information about what biofeedback is, how it works and how long the treatment is. A member of the team will speak to you about everything in this leaflet, but if you have any questions, please ask us.
