Upper Gastrointestinal tract endoscopy (OGD)- Introduction
 

This information about upper gastrointestinal endoscopy will help you understand more about the test to find the cause of your symptoms. The test is sometimes called a 'gastroscopy' or simply an 'endoscopy'. If you still have questions, ask your doctor for more information.

What is an Upper GI Endoscopy?
Upper GI endoscopy is a test which allows the doctor to look directly at the lining of the oesophagus (the gullet), the stomach and around the first bend of the small intestine - the duodenum. In order to do the test, an endoscope is passed through your mouth into the stomach. The endoscope is a long flexible tube (thinner than your little finger) with a bright light at the end. Looking down the tube, the doctor gets a clear view of the lining of the stomach and can check whether or not any disease is present. It's also more accurate than X-ray films for detecting inflammation, ulcers and tumours of the oesophagus, stomach and duodenum. Sometimes the doctor takes a biopsy- a sample of tissue for analysis in the laboratory. The tissue is removed painlessly through the endoscope, using tiny forceps.
