Endoscopic Retrograde Cholangiopancreatography

Overview

Endoscopic retrograde cholangiopancreatography (ERCP) uses a dye to highlight the bile ducts and pancreatic duct on X-ray images. A thin, flexible tube (endoscope) with a camera on the end is passed down your throat and into your small intestine. The dye enters the ducts through a small hollow tube (catheter) passed through the endoscope.
