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

A 13-year-old boy with documented recurrent acute pancreatitis underwent endoscopic retrograde cholangiopancreatography (ERCP). Cholangiogram revealed a long common channel of approximately 2.5 cm in length (arrow) and the pancreatic duct taking off from the mid-common bile duct (dashed arrow). Sphincterotomy provided symptom relief. In the right upper quadrant, staples from prior cholecystectomy are present.
