Complications of ERCP.

Endoscopic retrograde cholangiopancreatography (ERCP) is performed commonly for therapy. Its role in pancreaticobiliary diagnostic imaging has significantly decreased over time. Despite advances in our knowledge of the risk factors, complications, (especially post-ERCP pancreatitis), remain a significant problem. This review highlights the risk factors as related to the patient, procedure and the endoscopist, and the possible means to prevent complications. The best way to avoid any complication is "to avoid any procedure where the indication is not strong" and especially to refrain from doing diagnostic ERCP when alternate noninvasive imaging such as magnetic resonance cholangiopancreatography is available.
