We herein report a case of perihilar cholangiocarcinoma detected 10 years after surgical treatment for distal cholangiocarcinoma with congenital biliary dilatation (CBD). A 52-year-old woman underwent extrahepatic bile duct resection for distal cholangiocarcinoma identified in CBD 10 years ago. Three years after the initial operation, she developed repetitive cholangitis due to stenosis of the cholangiojejunostomy. Additionally, 5 years after the initial operation, abdominal CT scan showed development of hepatolithiasis and hilar bile duct thickening. However, she refused further treatment and careful follow up was continued. In this year, CT scan revealed irregular thickening of the hilar bile duct. Biopsy from this region led to the definitive diagnosis of remnant hilar bile duct carcinoma. She underwent left hepatic trisectionectomy to achieve curative resection. Six months after the operation, she was still alive without recurrence.
Careful observation and adequate treatment is important during postoperative follow up for CBD.
