Risks
Complications from gastrointestinal endoscopy are rare.
There is a slight risk of puncturing your throat (esophagus), stomach, or upper
small intestine (duodenum) and require surgery to repair. There is also a
slight chance of infection after an endoscopy.
Bleeding may also occur from the test or if a tissue sample
(biopsy) is taken, but this usually stops on its own without treatment. If you
vomit during the examination and some of the material you vomit enters your
lungs,
aspiration pneumonia is a possible risk. If it
develops, it can be treated with antibiotics.
People who have certain types of heart murmurs, artificial heart
valves, or previous infections of a heart valve will need antibiotics before
and after the test to prevent infection. An irregular heartbeat may occur
during the test but nearly always subsides on its own without treatment.
People with abnormal heart valves or an artificial heart valve may
receive antibiotics before and after the procedure to prevent infection. The
procedure has more risk for people with serious heart disease, older adults,
and those who are frail or physically weakened. Although complications are
rare, you should discuss your specific risks with your doctor.
