Endoscopic Retrograde Cholangiopancreatography

ERCP, or endoscopic retrograde cholangiopancreatography, uses endoscopy and X-ray to diagnose and treat diseases of the gallbladder, bile ducts, pancreas and liver. ERCP may be used to enlarge the opening of a duct, put a stent in place to permit the duct to drain, remove gallstones trapped in the duct, or obtain tissue samples of the liver or pancreas for biopsy.
