What Is Endoscopic Retrograde Cholangiopancreatography?

ERCP is a specialized technique used to study the ducts of the gallbladder, pancreas, and liver. ERCP combines the use of X-rays and an endoscope, a long, flexible, lighted tube, through which a physician can view the inside of the stomach, duodenum, and ducts in the biliary tree and pancreas. ERCP may be used to discover the underlying cause of jaundice, upper abdominal pain, or unexplained weight loss.
