An upper GI and small bowel series is a special X-ray test. It allows the doctor to see the upper part of the digestive tract. This area includes the esophagus, the stomach, and the small intestines.

Who is a candidate for the test?

This test may be ordered to investigate many different problems. These include:

This test may also be used after surgery has been performed on the upper digestive tract.

How is the test performed?

The person is asked to undress and put on a hospital gown. The technologist will then take a regular X-ray of the abdomen. Next, the individual drinks a large glass of a chalky liquid called barium. The barium coats internal structures and makes them show up on the X-ray film. Sometimes, the person is also asked to swallow a carbonated powder to produce gas in the stomach. This helps provide contrast to the barium and makes visualization easier.

As the barium flows through the digestive tract, multiple X-rays are taken with the person in different positions. This is so the entire gut can be seen from all sides. During the test, the person taking the X-rays may press on the individual's stomach with a lead glove or paddle. X-rays are usually done every 15 or 30 minutes to follow the dye as it moves through the digestive tract. When the barium reaches the large bowel, the test is finished.
