- You may be asked to stop certain medications up to 72 hours before the test.
- You will be with him/her during the entire test.
- Explain to your child how the test is done (The nurse will help you do it before the test. It may be helpful for your child to bring a favorite toy to make your child more comfortable during the procedure.)

Description of test
- An intravenous line (IV) will be started.
- Your child will be taken to the GI procedure room.
- Anesthesiologist will give medicine to help your child sleep when catheter is placed.
- The catheter will be passed through the rectum and into the colon with help of a camera. The catheter extends from rectum into the entire length of the colon.
- The tube will be secured with tape on the inner thigh.
- Once the catheter is placed, your child will be taken to the recovery room (PACU).
- Once your child is awake, he/she will be then taken to the GI Motility Suite (2 people can come in).
- The catheter will be attached to the Manometry machine and computer.
- First, the test will determine how your child’s colon works at rest (fasting).
- Your child will be given food and medication as part of the test. Please do not allow your child to eat or drink until instructed to do so by staff.**

After the test
- Your child may return to a normal diet, play and usual activities once the test is completed and the tube is removed from the colon and rectum.
- Your doctor will discuss the results of the test with you.
