Contemporary surgical approach to hilar cholangiocarcinoma.
BACKGROUND: The diagnostic and therapeutic approach to hilar cholangiocarcinoma and thus the prognosis have changed significantly over the last two decades. Nonetheless, hilar cholangiocarcinoma presents a complex surgical challenge. OBJECTIVES: To assess the outcome of the radical approach for the management of types III and IV hilar cholangiocarcinoma. METHODS: We conducted a retrospective single-center study. Preoperative diagnosis was based on ultrasound, computed tomography and selective percutaneous cholangiography without tissue diagnosis. Surgery was radical and included en-bloc liver, extrahepatic biliary tree and hilar lymph nodes resection, followed by biliary reconstruction with hepaticojejunostomy. RESULTS: Fifteen patients (mean age 49 years, range 24-72) were managed accordingly. Anatomic classification of the biliary involvement was Bismuth-Corlette type IIIA (n=4), type IIIB (n=3) and type IV (n=8). The surgical procedures performed included four right hepatic lobectomies, five left hepatic lobectomies and six trisegmentectomies (all extended to the caudate lobe). Complete negative resection margins (RO) were accomplished in 12 cases (80%). Regional lymph node metastases were detected in five cases. There were two perioperative mortalities. Long-term follow-up (mean 30 months, range 6-72) revealed local recurrences in two cases, distant metastases in three, and both local and distant in two cases. Eleven patients are alive and 6 are without evidence of disease. The overall 2- and 5-year survival is 78% and 38% respectively. CONCLUSIONS: In selected patients the aggressive surgical approach to hilar cholangiocarcinoma is justified and can result in long-term survival.[1]References
