Upper Gastrointestinal (UGI) Series
What To Think About
- A gastrointestinal (GI) motility study may be done if the squeezing motions of the small intestine are not normal during the UGI series and small bowel follow-through. The movement of the barium through the lower intestinal tract is recorded every few hours for up to 24 hours. A Reference barium enema Opens New Window or Reference colonoscopy Opens New Window may be needed to confirm the diagnosis.
- Upper endoscopy is done instead of a UGI test in certain cases. Endoscopy uses a thin, flexible tube (endoscope) to look at the lining of the esophagus, stomach, and upper small intestine (duodenum). For more information, see the medical test Reference Upper Gastrointestinal Endoscopy.
- The UGI
- May not show irritation of the stomach lining (gastritis) or esophagus (esophagitis) or ulcers that are smaller than about 0.25 in. (6 mm) in diameter.
- Cannot show an infection with the bacteria Reference Helicobacter pylori Opens New Window, which may be a cause of stomach ulcers.
- A Reference biopsy Opens New Window cannot be done during the UGI if a problem is found.
