Endoscopic Retrograde Cholangiopancreatography (En-Dah-Skah-Pik Ret-Ro-Grade Ko-Lan-Jee-O-Pan-Kree-A-Tog-Ra-Fee):
ERCP. A procedure to x-ray the pancreatic duct, hepatic duct, common bile duct, duodenal papilla, and gallbladder. In this procedure, a thin, lighted tube (endoscope) is passed through the mouth and down into the first part of the small intestine (duodenum). A smaller tube (catheter) is then inserted through the endoscope into the bile and pancreatic ducts. A dye is injected through the catheter into the ducts, and an x-ray is taken.
