Complications of endoscopic retrograde cholangiopancreatography

During the more than 50-year history of endoscopic retrograde cholangiopancreatography (ERCP), it has become an almost exclusively therapeutic procedure from a diagnostic method. This was the result of the evolution of far less invasive diagnostic procedures and the identification of its complications. Nowadays, being aware of these complications is fundamental. Remarkable knowledge has been gathered over the past decades about the risk factors, preventive methods and endoscopic treatments. A significant number of relevant publications from Hungarian authors can be found in this field. In our article, we summarize the complications of ERCP, their definitions, severity classifications, risk factors, prophylactic methods and endoscopic treatments.
