Training in Endoscopy: Endoscopic Retrograde Cholangiopancreatography

Endoscopic retrograde cholangiopancreatography (ERCP) is a key endoscopy skill used to diagnose and treat pancreatobiliary diseases. However, its diagnostic use is decreasing in favor of other less invasive methods such as magnetic resonance cholangiopancreatography and endoscopic ultrasound. Alternatively, its use has become more important in the therapeutic area. ERCP trainees must know the anatomy and physiology of the pancreatobiliary system, several key basic skills, and complications of a successful procedure. This article briefly introduces basic ERCP knowledge, techniques, numbers necessary to achieve competency, and complications for new ERCP operators.
