Endoscopy is a safe procedure, and when it is performed by a physician with specialized training in these procedures, the complications are extremely rare. Risks may include irritation of the vein where the medication was administered; reaction to the medication or sedatives used; complications from pre-existing heart, lung, or liver disease; bleeding at the site of a biopsy or removal of a polyp (which, if it occurs, is almost always minor and rarely requires transfusions or surgery). Major complications such as perforation (punching a hole through the esophagus, stomach, or duodenum) are rare, but usually require surgical repair.
