[Indication and operative techniques of extended right hepatic lobectomy for advanced gallbladder cancer].
Gallbladder cancer extends directly to the hepatic hilum and/or the right portal pedicle in the hepatic hilum type and the bed and hilum type of disease. Extended right hepatic lobectomy (ERHL), caudate lobectomy, lymph node dissection, and biliary reconstruction are necessary for radical resection of the tumor. It was previously thought that this extensive surgery carried high risk, with a hospital death rate of 20%, and had little survival benefit. However, it is now feasible with lower risk due to improvement in biliary decompression techniques, prevention of intrahepatic segmental cholangitis, introduction of preoperative portal embolization, etc. Long-term survival has been achieved after surgery unless there is hepatic, peritoneal, or paraaortic metastasis. Hilar hepatic involvement is more advanced in gallbladder cancer than in bile duct cancer, and portal vein resection and reconstruction are inevitable. All six such patients in our department over the past two years underwent concomitant portal reconstruction and have survived postoperatively.
