The patient was a 66-year-old woman who had undergone low anterior resection for rectal cancer. Although she received adjuvant chemotherapy after the surgery, a 1.5 cm hepatic metastasis was observed in segments 4/8. Radiofrequency ablation (RFA) was performed for the metastatic tumor. Approximately 1 month after RFA, a local recurrence was identified together with intrahepatic bile duct dilation in the right lobe of the liver. Extended right hepatic lobectomy and left intrahepatic cholangiojejunostomy were performed to remove the tumor. Histopathological examination of the resected specimen showed a liver metastasis from the rectal cancer with stricture of the bile duct although the bile duct was not involved in the tumor. This suggested that the bile duct stricture was caused by RFA and not by the recurrent tumor. Currently, the patient IS alive with no recurrence 14 months after the surgery. This case suggests the importance of salvage surgery for recurrent tumors after RFA therapy, especially in the case of RFA-related complications in conjunction with the tumor.
