BACKGROUND/AIMS We investigated the influence of HTK solution against natural killer T cells and thymic T cells in liver graft before and after perfusion in adult living related donor liver transplantation. METHODOLOGY Graft samples were obtained before liver resection, after perfusion, and one hour after liver transplantation. Flowcytometry analysis was(More)
We report a rare case of intrahepatic cholangiocarcinoma (IHCC) arising many years after excision of a type IV-A congenital choledochal cyst. A 44-year-old man was transferred to our hospital with acute cholangitis more than 34 years after several operations for congenital biliary dilatation.
