Abstract

The endoscopic retrograde cholangiopancreatography (ERCP) has become a commonly performed endoscopic procedure in biliary pathology. ERCP is a relatively safe procedure. however, there are chance of potentially severe complications; pancreatitis, hemorrhage, infection, and perforation. Duodenal perforation, uncommon but severe complication of ERCP, occurred in less than 1% of most series. According to the related mechanism, anatomical location, and the severity of injury, three to four distinct types of perforations have been described. We experienced the barotrauma associated duodenal perforation during endoscopic hemostasis in patient with EST site bleeding. This duodenal perforation was related with excessive air inflation to maintain the patency of a lumen. Endoscopists performing ERCP should bear in mind that continued air inflation may lead to duodenal perforation. (Korean J Gastrointest Endosc 2004;29:222⁣227)
