1 Medical Imaging Department NHS Foundation Trust Patient Information Ct (Computed Tomography) Colonography - Picolax Every Matters 1

2 Your Doctor would like you to attend for a Ct Colonography This leaflet will help to explain what a CT Colonography is and answer some of your questions. Please read the entire leaflet immediately as you may need to contact the Department with important information. What is a CT Colonography? This is a special type of X-ray examination looking specifically at your Colon (large bowel) but also at other organs in your abdomen and pelvis. The examination will involve taking a strong laxative to clean your bowel out, so that the Consultant Radiologist can examine the bowel without faeces hiding any detail. The examination also involves an injection of a drug that relaxes the bowel and therefore improves the image quality, which may be degraded by bowel movement. It also uses a special dye injected in your vein that outlines blood vessels and other organs, further highlighting any abnormality that may be present. Before taking the enclosed laxatives. What you need to tell the staff in x-ray about If you have any of the following please contact us as soon as possible. Diabetes Kidney impairment/failure Myeloma Severe acute inflammatory bowel disease Difficulty in swallowing or have a peg feeding tube If there is any chance that you could be pregnant 2

3 Before taking the enclosed laxatives - information for women If you are using the contraceptive pill it may become ineffective whilst taking the laxative and we advise that you take extra precautions to prevent pregnancy at this time. For women of child bearing age, this examination must be performed within the first 10 days of your last menstrual period. If this appointment is outside this criteria please contact the Department as soon as possible. Information about Picolax Please read the product information leaflet enclosed with the laxatives for a list of potential side effects. Picolax is a strong laxative and may cause you to become dehydrated; this is especially the case if you take water tablets. If you are diabetic we would like you to contact the Department as we may decide to give you an alternative laxative. Do you need to follow a special diet? To prepare you for this examination it is important that your bowel is completely empty. You must not eat any solid food on the day you take the laxatives and up to your appointment. You must take the enclosed laxatives. The product information leaflet states that you can eat food with picolax, however for this procedure we ask that you do not eat any solid food. 3

4 What can you eat and drink? The day before you have the CT Colonogram your diet should consist entirely of fluids, to prevent dehydration drink plenty of fluids, try to drink approx 4-5 pints (equivalent of litres) during the day including: Tea Coffee Milk You may also have plain yoghurt, ice cream and jelly, in moderation, for example: one bowl of yoghurt and/or one bowl of jelly and icecream. You may also suck boiled sweets and pastilles. A suggested meal plan for diabetics is available on the last page of this leaflet. Medication Mineral drinks Smooth fruit juice Squash Build-up Complan Oxo If you take any form of medication, please continue to take it as normal, but we suggest that you leave a minimum of 1 hour between taking the medication and taking the laxative as you may not absorb the medication. However if you are taking iron tablets please stop taking them 7 days before your appointment. If you are taking any regular laxatives, including bulk forming laxatives such as Fybogel and ispaghula husk. Please stop taking these at least 2 days before your appointment. When do you need to take the enclosed laxatives? These need to be taken the day before the examination. The first sachet of picolax should be taken at 8.00 am. Bovril Clear soup 4

5 Mix the contents of one sachet in a cup of cold tap water (approximately 150 mls). Stir for 2-3 minutes and drink the solution. If it becomes hot, wait until it cools sufficiently to drink. IMPORTANT: Please avoid plastic cups/containers. The second sachet should be taken at 4.00pm and mixed as before. THE POWDERS YOU ARE TAKING ARE A POWERFUL LAXATIVE, which will cause several bowel movements and can act quite quickly. You should stay within easy reach of a toilet. On the day of your appointment you may find that the laxative is still working, this is normal. On the day of your appointment continue to drink fluids from page 4. Due to the laxatives you may suffer from dehydration. This may lead to headache, dizziness and mild confusion. It is therefore important that you drink fluids from the list on page 4 throughout the process. Allergic reactions Allergic reactions are extremely rare but as with all medications possible. A reaction could be a rash, itchy skin, redness and swelling, difficulty in breathing and wheezing. If you experience any of these symptoms seek medical help. In the case of extreme reactions attend Accident and Emergency Department and please bring any packaging. Please note that diarrhoea and anal (bottom) irritation is common and is not a sign of an allergic reaction. For other possible side effects please see the product information leaflet. 5

6 What happens when you arrive in the Medical Imaging Department? Please bring this appointment letter and on arrival report to the second reception desk in the x-ray (medical imaging) Department, if you have an evening appointment please report to the first reception desk. Once registered, they will advise you where to wait. What does the examination involve? You will be asked to change into a hospital gown and lie on the CT scan table. If you wish you can bring your own additional dressing gown, as we are no longer able to provide one. The Consultant will then speak to you and answer any questions you may have before the examination starts. A needle will then be put into a large vein in your arm for the dye used in the scan and to give you the drug to relax your bowel, this may cause you to experience blurred vision for approx 45 minutes, we ask that you do not drive while your vision is impaired. The Consultant will then insert a small tube into your rectum (back passage) and gently inflate your bowel with gas using a special pump. You will then be asked to lie on your back and the scan (special x-rays) will be performed whilst injecting a dye into your vein using the needle already in place. Once you have the scan you will be asked to roll flat onto your tummy to have the scan repeated in this different position. Again this is to improve accuracy in detecting any small abnormality that may be present in your large bowel. How long will the examination take? The examination usually lasts between minutes. During the procedure you may experience abdominal fullness but it should not be painful. 6
