Gallbladder problems and procedures - endoscopic retrograde cholangiopancreatography

endoscopic retrograde cholangiopancreatography (ERCP) ERCP is a way to examine your pancreas, pancreatic duct, common bile duct, and/or sphincter of Oddi. Your doctor uses a long narrow tube called an endoscope to look at these parts of your body and he or she may use contrast dye and x- rays to highlight them. Your doctor may also use ERCP to try to remove any stones or blockages he or she may find.
