title: Six-year survival following left hepatic trisectionectomy with simultaneous resection of the portal vein and right hepatic artery for advanced perihilar cholangiocarcinoma without lymph node metastases: report of a case.
abstract: We report a case of survival for more than 6 years following left hepatic trisectionectomy and caudate lobectomy with simultaneous resection of the portal vein and right hepatic artery. The patient was a 65-year-old woman admitted to a local hospital with obstructive jaundice. The patient was diagnosed with perihilar cholangiocarcinoma and referred to our hospital. The tumor was located mainly in the left hilar region and occluded the left portal vein; furthermore, it involved the right portal vein and the right hepatic artery. The patient underwent left hepatic trisectionectomy and caudate lobectomy with simultaneous resection of the portal vein and right hepatic artery. The histological findings revealed that the tumor had invaded the portal vein and surrounded the right hepatic artery without any lymph node metastases. Microscopic curative (R0) resection was achieved. The patient is now healthy and still alive 6 years and 6 months after the surgery without any recurrence. Precise preoperative evaluation of the tumor and R0 resection by extended surgery contributed to a satisfactory outcome.
