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.
