ERCP

During an endoscopic retrograde cholangiopancreatography, a catheter is advanced through the endoscope and inserted into the pancreatic or biliary ducts. A contrast agent is injected into these ducts and X-rays are taken to evaluate their caliber, length and course. Narrowing, stones, and tumors in the ducts can be identified in the X-rays.
