During ERCP, doctors use an endoscope and X-rays to view injectable dye as it travels through pancreatic and bile ducts. ERCP helps providers diagnose and treat gallstones, inflamed gallbladders, bile duct blockages, pancreatitis, pancreatic cancer and other conditions.
Gastroenterologists (doctors who specialize in gastrointestinal disorders) use ERCP to examine and treat problems that affect the liver, pancreas, gallbladder and bile ducts.

Some people have an allergic reaction to the IV dye used during the X-ray part of the procedure. If this happens, your doctor will quickly administer medication to stop the reaction. Other rare but potential complications include:
