This test measures the pressure or contractions in the stomach and small intestine to determine how well the stomach and the duodenum work together.

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.
- During the upper endoscopy (EGD) procedure, the doctor will use the camera to place a narrow catheter through the nose into the stomach and small intestines. (For patients with G/GJ tubes, the tube will be placed via the existing G tube opening.)

- 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.
