Upper Gastrointestinal (UGI) Series
What is an Upper Gastrointestinal (UGI) Series?
An Upper Gastrointestinal (UGI) Series, also known as a barium swallow, is a diagnostic procedure that helps doctors visualize and examine the upper digestive tract. It provides valuable information about the structure and function of the esophagus, stomach, and duodenum. The procedure involves the use of contrast material, usually barium, which helps highlight the organs during X-ray imaging.
Why is an Upper Gastrointestinal (UGI) Series performed?
An UGI Series is typically performed to evaluate various conditions and symptoms, including:
- Difficulty swallowing
- Unexplained pain or discomfort in the upper abdomen
- Reflux (GERD)
- Blockage or narrowing of the esophagus, stomach, or small intestine
- Ulcers
- Tumors
- Inflammation or infection
- Gastric motility disorders
- Malabsorption
- Hiatal hernia
How to prepare for an Upper Gastrointestinal (UGI) Series?
Prior to the procedure, there are specific preparations that need to be followed. Your doctor will provide you with detailed instructions, which may include the following:
- Fast for a certain period of time before the test, usually overnight.
- Avoid eating or drinking anything, including medications, several hours before the test.
- Inform your doctor if you are pregnant or suspect you might be.
- Inform your doctor of any allergies or previous adverse reactions to contrast materials.
- Discuss any current medications, as some may need to be temporarily discontinued.
What happens during an Upper Gastrointestinal (UGI) Series?
During the UGI Series, you will be positioned on an X-ray table, and a radiology technologist will administer the contrast material to swallow. The barium coats the lining of the esophagus, stomach, and duodenum, making them clearly visible on X-ray images.
The technologist may take different X-ray images at specific intervals to capture the barium as it passes through your digestive system. You may be asked to move into different positions or briefly hold your breath to capture accurate images.
Are there any risks or side effects?
UGI Series is generally considered safe, with minimal risks and side effects. However, it's important to note the following:
- Rarely, some individuals may experience an allergic reaction to the contrast material used, although this is extremely rare.
- There may be temporary constipation or white-colored stools due to the presence of barium in your digestive system. Drinking plenty of fluids helps eliminate the barium from your body.
How to interpret the results?
The images obtained from the UGI Series are carefully examined and interpreted by a radiologist. They will assess the structures, look for abnormalities, and provide a detailed report to your referring physician.
Your doctor will discuss the findings with you and determine the next steps, such as additional tests, treatments, or referrals to specialists if needed.
Conclusion
An Upper Gastrointestinal (UGI) Series is a valuable diagnostic tool to assess the upper digestive tract. It helps identify various conditions and provides important information for appropriate treatment planning. If you are experiencing symptoms related to your upper abdomen or have swallowing difficulties, consult with Foley James D MD regarding the possibility of an UGI Series.
