  "abstract": "This case describes hilar cholangiocarcinoma with pancreaticobiliary maljunction (PBM), pancreas divisum, and a type V right hepatic duct variant. Preoperative computed tomography (CT) with three-dimensional (3D) reconstruction and magnetic resonance cholangiopancreatography (MRCP) clarified the complex ductal anatomy and informed reconstruction. After local extrahepatic bile duct resection with hilar lymphadenectomy, the patient initially recovered uneventfully. At 5 months, CA19-9 was 4,360 U/mL, CEA was within the reference range, and imaging raised concern for recurrence. The patient died at home 6 months after surgery; multiorgan failure was reported, but no autopsy was performed. This case emphasises the need for detailed preoperative mapping of coexisting biliary and pancreatic ductal variants to guide operative planning and biliary reconstruction. It also illustrates the potential oncological limitations of local extrahepatic bile duct resection in the setting of incomplete disease staging.",
