Gastroscopy

A gastroscopy is a procedure that allows your gastroenterologist to examine the lining of your oesophagus, stomach and the upper small intestine using a thin, flexible camera that is introduced through the mouth. The procedure is performed under sedation, which is administered by an anaesthetist. A gastroscopy typically takes 10–20 minutes and is considered a day procedure (admission and discharge on the same day). Detailed preparation instructions will be provided prior to each procedure.

Why Is a Gastroscopy Performed?

• Investigation of symptoms such as heartburn, reflux, difficulty swallowing, nausea, or upper abdominal pain
• Investigation of iron deficiency or anaemia
• Screening for coeliac disease
• Surveillance of Barrett's oesophagus
• Removal or biopsy of polyps or lesions
