Core Tip
Core Tip: Common bile duct (CBD) stump fistula is an exceedingly rare complication of choledochojejunostomy. This case report suggests that pancreaticobiliary reflux, characterized by high drainage amylase, may contribute to CBD stump fistula, potentially via pancreaticobiliary maljunction or sphincter of Oddi dysfunction. Early recognition of this possible mechanism may be clinically important. Therapeutic endoscopic retrograde cholangiopancreatography, including pancreatic duct sten
