Abstract
We encountered a case of alveolar echinococcosis of the liver that was treated by extended left lobectomy with hepatic artery and biliary resection. A 58-year-old woman complained of jaundice and itching, and a hepatic tumor of the left lobe was noted by abdominal US and CT. She was finally diagnosed as having alveolar echinococcosis of the liver by serological tests. Endoscopic retrograde cholangiography showed an obstruction of the left hepatic duct and stenosis of the upper bile duct. Based on these observations, the echinococcosis seemed to extend to the extrahepatic bile duct. She received extended left lobectomy. Echinococcosis lesions extended to the hepatoduodenal ligament, and involved the upper bile duct and proper hepatic artery. We performed resection of the proper hepatic artery and reconstructed it between the right hepatic artery and proper hepatic artery. Bile duct resection and reconstruction (hepaticojejunostomy) was also performed. In conclusion, we succeeded in extended left lobectomy with reconstruction of the hepatic artery in a case of highly extended echinococcosis.
