Upper Gastrointestinal Tract Radiography (Upper GI)

An upper gastrointestinal series (UGI) is a radiographic (X-ray) examination of the upper gastrointestinal (GI) tract. The esophagus, stomach, and duodenum (first part of the small intestine) are made visible on X-ray film. An upper GI series may be performed to diagnose structural or functional abnormalities of the esophagus, stomach, and duodenum. These abnormalities may include, but are not limited to:

• Ulcers. Ulcers may be gastric (stomach) or enteric (duodenum)
• Gastroesophageal reflux disease (GERD)
• Inflammation or infection
• Benign tumors. Nonmalignant
• Cancer
• Structural problems. Such as diverticula, strictures, or polyps (growths)
• Hiatal hernia. Upward movement of the stomach, either into or alongside the esophagus
• Dysphagia. Difficulty swallowing
• Motility disorders. Difficulty moving foods through the pharynx or esophagus
• Chest and/or abdominal pain
• Unexplained vomiting and/or indigestion
• Bloody bowel movements
