What is ERCP?
ERCP is performed by using a duodenoscope. The scope is inserted through esophagus to the stomach and into the second portion of duodenum. Once the papilla of Vater is identified, the bile ducts and pancreatic ducts are injected with contrast material through a small plastic catheter, and x-ray pictures are taken. When these x-ray pictures show stones or obstructions, they can often be treated during the same ERCP examination.
