Upper Gastrointestinal Endoscopy
Why It Is Done
- Find problems in the upper gastrointestinal
(GI) tract. These problems can include:
- Inflammation of the esophagus (esophagitis) or the stomach (gastritis).
- Reference Gastroesophageal reflux disease (GERD) Opens New Window.
- A narrowing (stricture) of the esophagus.
- Enlarged and swollen veins in the esophagus or stomach (varices).
- Reference Barrett's esophagus Opens New Window, a condition that increases the risk for developing esophageal cancer.
- Reference Hiatal hernia Opens New Window.
- Find the cause of vomiting blood (hematemesis).
- Find the cause of symptoms, such as upper abdominal pain or bloating, trouble swallowing (dysphagia), vomiting, or unexplained weight loss.
- Find the cause of an infection.
- Check the healing of stomach ulcers.
- Look at the inside of the stomach and upper small intestine (duodenum) after surgery.
- Look for a blockage in the opening between the stomach and duodenum (gastric outlet obstruction).
Endoscopy may also be done to:
- Check for an esophageal injury in an emergency (for example, if the person has swallowed poison).
- Collect tissue samples (biopsy) for examination in the laboratory.
- Remove growths from inside the esophagus, stomach, or small intestine (gastrointestinal polyps).
- Treat upper gastrointestinal bleeding, including bleeding caused by engorged veins in the esophagus (esophageal varices).
- Remove foreign objects that have been swallowed.
- Look for bleeding that may be causing a decrease in the amount of oxygen-carrying substance (hemoglobin) found in red blood cells (Reference anemia Opens New Window).
