A gastroscopy is a camera test that allows direct visualization of the esophagus, stomach and duodenum (the first part of the small bowel). It can also be called an upper GI Endoscopy, or an OGD (esophagogastroduodenoscopy). A gastroscopy gives an excellent idea about what the upper gastrointestinal tract looks like. It is the best test available to diagnose esophageal and stomach cancers, and can also diagnose inflammation, ulcers and narrowing in the upper GI tract.

During the procedure if a polyp or abnormal tissue is found it can be removed by the doctor and tissue samples may also be taken for further analysis. Gastroscopy is a safe, effective means of diagnosing and treating a wide range of conditions affecting the digestive tract.
