ERCP update: diagnostic and therapeutic applications

Endoscopic retograde cholangiopancreatography (ERCP) is currently utilized to evaluate jaundice, both intra- and extrahepatic, and can differentiate between these by demonstrating specific anatomic lesions. ERCP is definitive in the evaluation of gallbladder disease when other modalities are indefinite. For the first time outside the operating room, the pancreatic duct can be opacified by ERCP. The newest application of ERCP, endoscopic papillotomy (EP), has revolutionized the treatment of common bile duct gallstones and stenosis of the duct, offering a safe and effective alternative to repeated surgery, especially in those patients at risk. Because of these diverse and effective applications, ERCP has become firmly established in our diagnostic armamentarium.
