The gastroscope is completely cleaned and disinfected between each patient to avoid the risk of transmission of serious diseases such as HIV or hepatitis.

There is a small risk of teeth being damaged during the procedure.

Serious complications of gastroscopy are rare, at less than one in 10,000 examinations.

However, complications can occur and include the following:

• Gastroscopy is considered to be a very accurate test. However, there is a risk that an abnormality may not be detected.
• Reaction to the sedative. This is very uncommon but is especially of concern in people who have severe heart disease or lung disease.
• Perforation (making a hole in the upper GI tract wall).

It is possible if these serious complications occur that you may require surgery or a blood transfusion.

Rare side effects can occur with any procedure. Death is extremely rare.

If you wish to have further details please discuss this with your endoscopist before the procedure.

If you have any of the following symptoms in the hours or days after gastroscopy you should contact Endoscopy Auckland or your specialist immediately: severe abdominal pain, black tarry motions, persistent bleeding, fever or other symptoms that cause you concern.
