Conditions

Hepatocellular carcinoma, Intrahepatic cholangiocarcinoma, Liver metastasis, Hilar cholangiocarcinoma

Interventions

Three-dimensional simulation of liver resection is performed with simulation software (OVA, Hitachi Medico
SYNAPSE VINCENT, FUJIFILM) utilizing the data of preoperative enhanced computed tomography (CT). The result of the simulation is transferred to a workstation. The workstation is carried into the op
