This is a test that allows the endoscopist to look into your oesophagus (gullet), stomach and duodenum (small bowel), using a small flexible tube (endoscope). This contains a camera so that the endoscopist can see the lining of the stomach to check for problems which might be causing your symptoms. This type of endoscopy is sometimes referred to as an upper endoscopy or an OGD. They are just different terms for a gastroscopy..
Sometimes the endoscopist takes a biopsy – a sample of the lining - for examination in the laboratory. A small piece of tissue is removed painlessly through the endoscope using tiny forceps. There are now very advanced endoscopes which are slimmer and make the test much more comfortable.
The endoscope is generally passed through the nose and into the gullet, however, if your nose is narrow or has been damaged it may not be possible to pass the nasal endoscope. If this is the case we will pass the endoscope through the mouth.
