ASO Author Reflections: Essential to Reduce Adverse Outcomes in Perihilar Cholangiocarcinoma Surgery—Portal Vein Embolization

Abstract

PASTMajor liver resection for perihilar cholangiocarcinoma is associated with 90-day mortality rates of up to 18% in Western series. 1 Posthepatectomy liver failure is the primary cause of the high perioperative mortality. 2 However, the golden standard preoperative procedure to reduce liver failure and mortality-portal vein embolization-is sparsely used in Western centers for patients with perihilar cholangiocarcinoma. 3,4 This is in contrast to Eastern centers, where application of portal vein embolization is liberal and mortality rates are lower. 3
