What tests are used to diagnose familial adenomatous polyposis?
If you have FAP, your child’s doctor may recommend genetic testing to look for the genetic change that causes the condition. Your child’s doctor may also recommend imaging tests, such as a CT scan or colonoscopy to look for polyps.
We diagnose FAP based on several factors, including a family history of FAP and/or colon cancer. We also diagnose FAP in children who have 100 or more polyps in the intestine or fewer than 100 polyps and a family history of the disease.
Why choose us for a colonoscopy for FAP?
If your child needs a colonoscopy, they’re in expert hands. Our gastroenterology and surgical teams are trained specifically to work with children. We use equipment and procedures designed with kids in mind. The child life team at Children’s Colorado is here to help prepare children for the procedure with age-appropriate information and support.
What to expect from a colonoscopy?
Most of the time, children do colonoscopy prep at home to remove stool from the colon. Your child will take oral prep medication or an enema.
During a colonoscopy, your child is under general anesthesia to keep them comfortable. Your child’s doctor uses a flexible tube with a camera to examine the colon. We remove any polyps we find and send them to our lab for analysis. The results typically take a few days.
