Gastroscopy

Gastroscopy is an examination of the inside of the gullet, stomach and duodenum. It is performed by using a thin, flexible fibre-optic instrument that is passed through the mouth and allows the doctor to see whether there is any damage to the lining of the oesophagus (gullet) or stomach, and whether there are any ulcers in the stomach or duodenum. Gastroscopy is effective, and has now replaced the use of X-rays in many cases. It helps the doctor see any abnormalities in the gullet, the stomach and the duodenum. It is precise and safe.

Through the gastroscope, the doctor can take samples or photographs of the mucous membrane. The most modern gastroscopes can also show the areas in the stomach on a TV screen, so that the mucous membrane can be studied thoroughly. This can be recorded on a videotape, and used for later comparison.
