Endoscopic Retrograde Cholangiopancreatography (ERCP)

ERCP is a technique that uses endoscopy and fluoroscopy to diagnose and treat problems of the biliary or pancreatic duct systems. The inside of the stomach and duodenum are visualized with the endoscope and dyes are injected into the ducts of the biliary tree and pancreas so they can be seen on X-rays.
