Gastroscopy

Gastroscopy

What is a gastroscopy?

It is an examination of the inside of your oesophagus (gullet), the stomach and the duodenum (the first bend of the small intestine). See the diagram. A thin, flexible tube approximately the size of a woman’s little finger (a gastroscope) is passed through the mouth into the stomach. The tip of the endoscope contains a light and a tiny video camera so that the endoscopist can see inside your gut, allowing the endoscopist to see what might be causing the symptoms that you are experiencing. (This procedure is sometimes called an endoscopy).

Preparation for the test

  • For this examination to be successful and allow a clear view of the stomach and colon, they must be as empty.
  • It is important to have nothing to eat or drink for 6 hours before your test.
