Cholangiocarcinomas are categorized as intrahepatic cholangio- carcinoma (iCCA), perihilar cholangiocarcinoma (pCCA), and dis- tal cholangiocarcinoma (dCCA) [1] . iCCA and pCCA are the second most common primary hepatobiliary malignant neoplasms [ 1 , 2 ]. Most patients with iCCA and pCCA have asymptomatic clinical course, highly aggressive nature and dismal prognosis [3] . Com- plete surgical resection offers the best possibility of long-term sur- vival but only a minority of patients are amenable to R0 resec- tion [4] . Tumor involvement of segmental bilateral intrahepatic bile duct, inadequate remnant liver volume or hepatic functional reserve due to underlying chronic liver disease, are key factors limiting the resectability of iCCA and pCCA. Liver transplantation (LT) provides an option for patients with unresectable iCCA and pCCA [4] .
