Upper GI Procedure: Step by Step
Contributed by Christine W., April 2016
The Upper GI is the upper gastrointestinal tract radiography. It uses a version of x-ray called fluoroscopy with an orally ingested contrast material, typically barium. This produces real time images of the esophagus, stomach, and small intestine. It allows us to see the internal organs in motion; to watch how the mixture is swallowed, moves through the esophagus into the stomach, and then leaves the stomach. If the x-ray only focuses on the pharynx and esophagus is called a barium swallow. It is a noninvasive procedure; your child is awake the entire time. It can help diagnose ulcers, tumors, inflammation of the esophagus, stomach or small intestine, hernias, scarring, abnormalities of the muscular wall of the GI tract, swallowing difficulties, reflux, unexplained vomiting, and blood in the stool.
