Adverse outcomes of endoscopic retrograde cholangiopancreatography: avoidance and management

Adverse outcomes of endoscopic retrograde cholangiopancreatography (ERCP) include technical failures and complications. Complications cause significant morbidity to patients and anxiety to endoscopists. The key to preventing complications is to understand which patients and procedures are at highest risk so that appropriate decisions can be made as to whether ERCP should be performed at all, and if so, how. Patients who need ERCP the least are often the ones most likely to develop complications. For marginal indications, ERCP should be avoided. Success rates are higher and complication rates lower for endocopists performing large numbers by endoscopists with adequate experience.
