What are possible complications of upper endoscopy?

Endoscopy is safe. Complications can occur, but are rare when the test is performed by physicians with specialized training and experience in this procedure. Bleeding may occur from a biopsy site or where a polyp was removed. It is usually minimal and rarely requires blood transfusions or surgery. Localized irritation of the vein where the medication was injected may cause a tender lump lasting for several weeks, but this will go away eventually. Applying heat packs or hot moist towels may help relieve discomfort. Other potential risks include a reaction to the sedatives used and complications from heart and lung diseases. Major complications; e.g. perforation (a tear that might require surgery for repair) are very uncommon; they occur less often than once in 10,000 tests.


It is important for you to recognize early signs of any possible complications. If you begin to run a fever after the test, begin to have trouble swallowing or have increasing throat, chest or abdominal pain; let your doctor know about it promptly.
