Endoscopic retrograde cholangiopancreatography (ERCP) in a patient with an anomalous pancreaticobiliary union and biliary cyst

A 16-year-old girl with documented recurrent acute pancreatitis underwent endoscopic retrograde cholangiopancreatography (ERCP). Cholangiogram revealed a long common channel of approximately 2 cm in length (dashed arrow) and the bile duct taking off from the pancreatic duct (arrow). A cystic biliary dilation is also present. Sphincterotomy provided excellent biliary and pancreatic contrast drainage.
