A Gastroscopy is a procedure that allows the Consultant to look at the lining of the oesophagus, stomach and first part of the small bowel (duodenum). A long flexible tube/scope (thinner than your finger) with a light and a camera inside is passed through your mouth into the oesophagus, stomach and duodenum. The procedure can take between 5-15 minutes. A biopsy may be taken if indicated. This will cause you no pain.
Gastroscopy is a safe test but there are some risks. Complications include, but are not limited to, perforation (tear) in approximately 1:2000 cases. Haemorrhage (bleeding) may occur at the site of the biopsy and nearly always stops on its own. These complications may require urgent medical treatment or surgical intervention (operation) which can carry risk to life and health.
You may continue to take essential medication. If you are taking anticoagulants (blood thinners) such as warfarin or plavix you should seek/receive specific advice from your doctor when the test is being organised. If you have any concerns about your diabetes you should contact the Unit for advice before you attend for your test.
