[Common bile duct fistula caused by hepatic arterial infusion chemotherapy]

We often use hepatic arterial infusion chemotherapy to control recurrence of metastatic cancer of liver. Recently, we encountered a case of common bile duct fistula caused by hepatic arterial infusion chemotherapy. A 61-year-old man had undergone right hepatic lobectomy for liver metastasis of gastric cancer, 7 months after total gastrectomy. A hepatic arterial infusion catheter was placed. Since then he has received continuous and/or bolus hepatic artery infusion of 5-FU, ADR and CDDP+5-FU. There was a recurrence of gastric cancer in segment 2 of the liver. On his second admission, when we administered contrast medium to the infusion port, a common bile duct was found.
