An Upper Gastrointestinal (G.I.) Gastroscope is an endoscopic instrument used to visually examine the upper gastrointestinal tract — which includes the esophagus, stomach, and the first part of the small intestine (duodenum).
It’s commonly used to diagnose and sometimes treat conditions like:
- Gastritis
- Ulcers
- Esophageal varices
- Tumors or polyps
- Causes of bleeding, pain, or swallowing difficulties
