Having a gastroscopy examination
A gastroscopy is a camera test that allows direct visualisation of the oesophagus, stomach and duodenum (the first part of the small bowel). It can also be called an upper GI endoscopy, or an OGD (oesophagogastroduodenoscopy).
A gastroscopy gives an excellent idea about what the upper gastrointestinal tract looks like. It is the best test available to diagnose oesophageal and stomach cancers, and can also diagnose inflammation, ulcers and narrowing in the upper GI tract. It also gives an opportunity to take small biopsy samples through the camera that can be looked at microscopically by a pathologist.
The gastroscopy can be done either after a local anaesthetic spray in the mouth, or after injection of a sedative. When you have a gastroscopy you are lying down on your left side. There will usually be 2 nurses in the room (one to stay by you and guide you through the test, and the other to help the endoscopist). The endoscopist passes the camera (which is thinner than your little finger) through the mouth, over the back of the tongue, and into the oesophagus. He/she will then guide the camera into the stomach and duodenum, having a careful look as it is done. If biopsy samples are done, tiny (a couple of millimetre) samples of the lining of the oesophagus/stomach/duodenum are taken using small forceps that are passed through the endoscope. Usually the whole procedure is complete within about 5 minutes.
For safety, and to ensure the stomach can be seen well, it is important that the stomach is empty for the test. It is therefore important that you follow the instructions from the endoscopy unit before the test. This will involve a period of fasting before the test takes place. You may also be asked to stop some of your medications for a period before the test, and you will be advised of this when booking.
A gastroscopy is a very safe test. There is a very small risk (1 in 10000) of a serious problem such as causing a bleed, or a perforation (a tear caused by the endoscope).
Your endoscopist should be able to tell you how the test looked before you go home. If biopsy samples are taken the results of the these may take a few days.
