Abstract
PURPOSE
Ex vivo liver resection and autotransplantation (ERAT) can be used to treat locally advanced tumors that are conventionally unresectable. Because the procedure is rare, there are very few reports in the literature. Recently, we performed ERAT for two cases of cholangiocarcinoma invading caudate lobe, the retrohepatic vena cava and hepatic veins, and investigated technical variations of this procedure.
METHODS
One patient was a 57-year-old man with liver caudate lobe metastasis from cholangiocarcinoma after pancreaticoduodenal resection five years ago, and the other patient was a 68-year-old man with caudate lobe cholangiocarcinoma. Both cases were considered to be unresectable by conventional resection due to the critical invasion of the retrohepatic vena cava along with the three hepatic veins. Therefore, ERAT was indicated in these two cases.
RESULTS
The liver along with the retrohepatic vena cava was removed, which was replaced by GORE-TEX synthetic artificial vessel grafts with angioplasty to reconstruct the inferior vena cava (IVC), and the GORE-TEX synthetic artificial vessel anastomosed to the right auricular appendage or the IVC to build the continuity of the IVC. Ex vivo caudate lobe hepatectomy was performed, along with the retrohepatic vena cava and hepatic veins, and subsequently the reconstruction outflow of hepatic venous was established using cold-preserved allogeneic vessels and falciform ligament. Finally, remnant of the liver was implanted by Piggyback liver transplantation. The hepatic vein, portal vein, hepatic artery and bile duct were anastomosed, and autotransplantation of the liver was completed. The patients were followed-up for 18 months and showed good liver function, with no recurrence of cancer.
CONCLUSIONS
ERAT should be considered as a therapeutic option for selected patients with cholangiocarcinoma invading caudate lobe, the retrohepatic vena cava and hepatic veins. It is crucial to reconstruct the outflow of hepatic venous according to different situations.
