Information for patients
This leaflet can be made available in other formats including large print, CD and Braille and in languages other than English, upon request.
This leaflet contains information regarding aftercare following the test you had today and also results.
A CT Colonoscopy is an X-ray examination. It is a type of body scan which looks at the large intestine (bowel or colon). The Radiographer will discuss the procedure with you and complete a health questionnaire.
You will be asked to lie down on the CT table on your left side, with your knees slightly bent.
A soft tube will then be gently inserted into your rectum (back passage). Carbon dioxide will be passed through the tube to inflate your bowel so that a doctor can see all parts of your bowel in the scan. This is done using an electronic pump so that the pressure inside your bowel is safely controlled. This can cause ‘windy’ discomfort for a short time.
Following your test, we recommend that you go to the toilet to try and remove as much of the carbon dioxide gas as possible.
You may also need to pass a bowel movement or some retained fluid.
Taking deep breaths will also help you feel more comfortable and remove some of the gas that was used.
A drink will be made for you if you would like one. As long as you are feeling ok, you are free to leave the department. You can resume your normal diet.Are there any side effects?
You should not experience any side effects from this test aside from some mild stomach pains.However, if you were to experience any severe pains in your stomach following your scan today, you should seek medical attention from your local A&E department.
Once your scan has been reviewed by a doctor and a report has been made, the results will then be sent to your doctor or consultant.The results will then be discussed with you at your next appointment with your doctor.References
