The digestive organs such as the esophagus, gastrointestinal tract, gall bladder and pancreas are the most easily metastasized to the liver [1], accounting for about 30%. Transfers portal vein, hepatic artery hematogenous metastasis and lymphatic metastasis, adjacent organ cancer such as gallbladder, stomach, pancreas lesions can be directly infiltrated to the liver disseminated. Metastatic liver cancer often multiple, mostly gray nodules, hard to the majority of the liver surface; lesion size
