Endoscopic Retrograde Cholangiopancreatography (ERCP)

ERCP is a diagnostic procedure that uses both X-rays and a long tube called an endoscope to examine the liver, pancreas, gallbladder and bile ducts. ERCP can be used to diagnoses problems such as tumor, gall stones, and blockage of the bile ducts. An ERCP can sometimes be used to treat problems related to gall stones.
