Gastroscopy Instructions



What is a gastroscopy?

A gastroscopy is an examination of the oesophagus (food pipe), stomach and duodenum (first part of the small bowel).

What happens during the examination?

Prior to the examination, you will be given a sedative into the vein that will make you comfortable during the procedure.  You will likely remember little or nothing about the procedure. The gastroscope is a thin, flexible tube with a light and camera at the end, that is passed through the mouth into the stomach. Tissue samples (biopsies) may be taken during the procedure. The examination usually takes 10-15min.

Are there any risks?

Complications of Gastroscopy are rare. You may experience a sore throat or have mild abdominal bloating from trapped air in your stomach. Reactions to the sedative and chest infection occur very rarely.

If you DO NOT have a mobile, you will need to phone 97961300 to obtain your admission time between 1230 pm-2pm the working day before.
