Cannulation of the papilla of Vater by endoscopy and retrograde cholangiopancreatography (ERCP).

Cannulation ofthe papilla of Vater by endoscopy and retrograde cholangiopancreatography (ERCP) New fibreoptic duodenoscopes allow an experienced endoscopist to visualize and cannulate the papilla of Vater in conscious patients with at least an 80% chance of achieving retrograde cholangiopancreatography-a technique with obvious diagnostic potential. The historical aspects have already been ade- quately covered.'-4 This review concerns the rapidly increasing world experience, with particular regard to technical problems, clinical relevance, and safety.
