What is Wilkes Syndrome?

Wilkes syndrome is a rare congenital anomaly where your superior mesenteric artery lies on top of your small intestine instead of behind it. If you are a normal weight, you may not notice any problems except for occasion pain and constipation. If you lose a lot of weight and you have this syndrome, the mesenteric artery can flatten your small intestine making it impossible for food, water or even your own bile to get through. If this happens, it can be corrected by having an anastomosis. The intestine is cut and put back together in front of the mesteric artery. This completely corrects the problem. Diagnosis of this problem can be made with push upper endoscopy and nMRI imaging.

What are dangers and side effects that are related to colonoscopy in children?

COLONOSCOPY FOR CHILDREN: This is a safe procedure for your child and here is more information off a medical site regarding children: Colonoscopy is a procedure in which a gastroenterologist looks at the inside of the large bowel (colon) using a long, flexible tube called a colonoscope. A colonoscope is a long flexible tube that has a light and a camera on the end. The colonoscope is inserted into the bottom (anus) and then slowly advanced along the large bowel. The bowel is carefully examined and small samples of bowel tissue (biopsies) are taken for further tests. The main reasons children need a colonoscopy are to find a cause for abdominal pain, diarrhoea and bleeding from the bowel. Children may need to be admitted the night before the procedure so that the bowel can be washed out, but can usually go home within a few hours of the colonoscopy. Preparing for a colonoscopy Before having a colonoscopy, the bowel needs to be completely empty. To make sure this happens your child must follow these directions: One week before: Stop taking medications that have iron in them. Four days before: Stop eating foods that have small seeds or pips in them, such as wholegrain bread, tomato, cucumber and nuts. The day before: All solid foods must be finished by 2.00pm. Your child can drink anything they like until 4.00pm - ie milk or juice. After 4.00pm your child may only drink clear fluids. * Clear fluids are drinks you can easily see through, including, water, apple juice, lemonade, cordial, jelly (not red or green), lemonade icy poles, weak black tea or coffee. Clear fluids do NOT include fresh fruit juice and milk. Bowel washout Most children need to have a special drink called a "bowel washout" the evening before a colonoscopy. This drink is very important as it empties the bowel, helping the doctor to see more clearly. If your child cannot drink the bowel washout at home they may need to stay in hospital the night before the colonoscopy so that the bowel washout can be given through a nasogastric tube. A nasogastric tube is a small thin tube, which is inserted through the nose and then passed down into the stomach. The bowel washout is then given through this tube over 4-6 hours. Your child may feel very full and may vomit. They will have diarrhoea for several hours. On the day: All children having a colonoscopy are given a general anaesthetic. This is a medicine that makes them have a special sleep so they don't see, feel or hear anything while the doctor examines them. (To find out more about anaesthetics, see the Anaesthetic Department web page). Your child must follow hospital fasting instructions, or the procedure may be postponed (you will need to book a new appointment). Your doctor or nurse should give you the fasting instructions, or you can get them from the RCH anaesthetic web page. Most medications can be taken as usual. Please talk to your child's doctor about this before the colonoscopy. Side effects Sometimes your child may have one or more of the following side effects after the colonoscopy. These usually get better without any special treatment. Nausea or vomiting: If your child feels sick, stop them eating and drinking for half an hour, after this they can start having sips of clear fluids. You can increase what they eat and drink slowly. Abdominal (tummy) pain and bloating: If the pain is mild, rest and have sips of clear fluids until feeling better. Sore throat: Sucking throat lozenges or sipping warm fluids can help. Bleeding: A small amount of blood might be seen in bowel actions (poo). This is usually from the biopsies (small samples of tissue) that were taken. Care after a colonoscopy After the colonoscopy your child can start to eat a light diet (for example jelly, soup, pasta, toast). They may return to their usual diet when they feel well enough. Babies can start breast-feeding, or drinking formula or water when they are awake. Children should have a quiet time following the colonoscopy, but should be able to return to their normal activities the next day. Young adults must not drive a car, operate machinery or make important decisions for the rest of the day (because of the anaesthetic). Children can usually go home on the same day as the colonoscopy. A responsible adult (over 18 years old) must go home with them. A nurse will give the responsible adult an instruction sheet, explaining the care needed after a colonoscopy. Please read the fact sheet Day Surgery - Care after gastrocopy or colonoscopy. When to come back Call the RCH switchboard on (03) 9345 5522 and ask to page the 'Gastroenterology Registrar' or your Gastroenterologist if your child has: Vomited more than 2-3 times. Vomit with more than 2-3ml (1/2 teaspoon) of bright red blood in it. Bowel actions (poo) with more than the expected amount of blood. Severe tummy pain or bloating. A high temperature (above 38 degrees Celsius). Difficulty swallowing. Come back for your follow up appointment as directed by your Gastroenterologist. Key points to remember The full amount of the bowel washout (drink) must be taken for the colonoscopy to be successful. Let the Gastroenterology Nurse Coordinator (RCH tel (03) 9345 5060) know if your child is unwell before the colonoscopy, eg, if they have a chest infection or a bad cold. Colonoscopy is a very safe procedure and complications are uncommon. Your doctor will discuss any possible complications with you.

What does a colonoscopy do?

A Colonoscopy is used to visually examine your entire colon and rectum for abnormalities.

For the exam, a colonoscope which is a long, flexible tube about the thickness of a finger is inserted into your rectum. A tiny video camera and light at its tip allows your doctor to view the inside of your colon. The pictures come up on a video screen the doctor watches as he/she moves the tube to where the suspected problem is. Both air and water can be added through the tube by the doctor to inflate and wash the area to get a better picture.

A colonoscopy can be relatively painless but anxiety often dictates the use of a mild sedative during the procedure.

A gastroenterologist most often performs the exam.

Is pain medication normally approved for the recovery time after a colonoscopy?

Colonoscopy is done under light sedation. You will be able to hear your doctor and move as he instructs, but you will not remember because the sedation causes a short period of amnesia. You will also not remember any discomfort you feel during the test. Within a very short time, the sedation wears off. The MOST you might feel after a colonoscopy is a little more gassy. But you will not have pain or aftereffects from the colonoscopy. Someone will need to drive you home as a precaution since you just had a med in your system.
