完全切石術後に肝内胆管癌を合併した肝内結石症の1例

Abstract

We experienced a case of hepatolithiasis associated with cholangiocar- cinoma occurring 32 months after removal of stones. The patient was a 57-year-old woman. There were histories of undergoing lithotomy two times under a diagnosis of hepatolithiasis After the second operation, stenosis was demonstrated at the 1st order of the intrahepatic bile duct, and 35 months after the second operation, the patient died of cholangiocarcinoma occurring around there. Hepatolithiasis is sometimes accompanied with cholangiocarcinoma. Even though the lithotomy is completely performed, cholan- giocarcinoma can develop around the stenotic bile duct, These findings may suggest that these areas have a potential for malignant changes. So we must pay special attention to these complications in following patients with hepatolithiasis. Resection including the stenotic bile duct and atrophic liver may be adopted while treating hepatolithiasis to avoid the occurrence of cholangiocarcinoma with a palliative intent.
