This procedure may also be known as a gastroscopy

The examination is performed using a long flexible instrument called a gastroscope which is about the width of your little finger.

It is passed through your mouth and into your stomach and duodenum (the first part of your small bowel).  It allows the Endoscopist to look directly at the lining of the oesophagus (gullet), stomach and duodenum.  It also allows tissue samples to be removed painlessly which can then be sent to the laboratory for analysis.

The test usually takes approximately 5-10 minutes, but you should expect to be in the department between 2-4 hours to allow for admission, procedure and recovery time.

You may have been referred by your hospital consultant or GP to investigate symptoms including, indigestion problems, weight loss, anaemia or monitoring of a pre-existing condition such as Barretts.
