Abstract: Although improvements in preoperative inaging, patient selection, and refined operative techniques have allowed a more radical surgical approach to treat hilar cholangiocareinoma, it still show considerable morbidity and mortality. We reviewed previous literatures for surgical treatments of hilar cholangiocarcinomas in surgery for hilar cholangiocareinoma. From the result we recommended that curative resection should be performed for hilar cholangiocareinoma, and negative superior margine is the most important factor to bengfit survival.
