A 71-year-old man was referred to our hospital, suspected gallbladder cancer. Contrast-enhanced computed tomography revealed a tumor with contrast effect from the gallbladder body to neck, and liver bed infiltration was also suspected. The extent of cancer was suspected up to the cystic duct, and there was no distant metastasis. Subsequently, S4a+S5 hepatic segmentectomy, extrahepatic bile duct resection, and regional lymphadenectomy were performed for the diagnosis of gallbladder cancer. Simultaneous liver metastasis measuring 5mm in diameter was found in the resected side of liver. The final pathological diagnosis was StageIVB. He had survived recurrence-free for 3 years and 3 months without adjuvant chemotherapy following surgery. In this case, long-term patient survival was achieved by performing S4a+S5 hepatic segmentectomy. In this case, a tumor thrombosis was formed in the portal vein near the gallbladder cancer, suggesting liver metastasis was formed via cystic vein.
