Esophagogastroduodenogram

Esophagogastroduodenogram is a medical imaging procedure also known as an upper GI series. It is used to visualize the esophagus, stomach, and the first part of the small intestine, the duodenum. The examination involves swallowing a contrast agent, typically barium sulfate, which coats the lining of these organs. As the barium travels through the digestive tract, X-rays are taken at various intervals, creating detailed images of the internal structures.

This diagnostic tool helps physicians identify and evaluate a range of conditions affecting the upper gastrointestinal tract. Common reasons for performing an esophagogastroduodenogram include diagnosing ulcers, inflammation, blockages, tumors, hernias, and abnormalities in the shape or movement of the esophagus and stomach. It can also be used to assess the effectiveness of treatment for certain gastrointestinal disorders.

The procedure is generally performed on an outpatient basis and requires the patient to fast for several hours beforehand. During the examination, the patient lies on an X-ray table and is asked to swallow the barium liquid. They may also be asked to change positions to ensure the contrast agent coats all parts of the upper GI tract. After the X-rays are taken, the barium is passed naturally through the digestive system. The images produced allow for a comprehensive assessment of the anatomy and function of the examined organs.
