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.
A gastroscopy may be advised if you have symptoms such as recurring indigestion, recurring heartburn, pains in the upper abdomen, repeated vomiting, difficulty swallowing, or other symptoms thought to be coming from the upper gut.
A gastroscopy is conducted under the influence of a local anaesthesia or a sedative. The patient is asked to swallow the tip of the endoscope after which the operator gently pushes it further down into the oesophagus, and the stomach and duodenum. The video camera at the tip of the endoscope sends pictures to a screen. The operator watches the screen for abnormalities of the oesophagus, stomach and duodenum. Air is passed down a channel in the endoscope into the stomach to make the stomach lining easier to see.
After the biopsy samples are collected, the endoscope is gently pulled out.
