We present here a case of recurrent rectal cancer liver metastasis that was managed with ante situm liver resection under total vascular exclusion (TVE) and venovenous bypass with hypothermic perfusion. A 58-year-old man who suffered with rectal cancer liver metastasis was transferred to our hospital in January 2006. A left lateral sectionectomy had been previously performed. Recurrent lesion developed in segments I, IV and VIII one year after the first hepatectomy. The tumor was 5 cm in diameter and it involved the confluence of the hepatic veins and the retrohepatic vena cava. An incomplete tumor-free margin and massive bleeding were expected with performing a conventional liver resection, together with vena cava reconstruction. Therefore, we planned an ante situm liver resection under TVE and venovenous bypass with hypothermic perfusion. After adhesiolysis, hilar dissection was carried out. The inflow to the medial segment was interrupted, and then the liver and inferior vena cava (IVC) were mobilized fully. During controlling the bleeding of a short hepatic vein, we found adhesion of the hepatocaval portion. Therefore, TVE and venovenous bypass were performed along with suprahepatic IVC transection. The long conduit of V5 was preserved during hepatic parenchymal dissection, and the paracaval portion of the caudate lobe was readily detached from the IVC. The suprahepatic IVC was reconstructed after V5 reconstruction with using the saphenous vein. Portal vein anastomosis was then conducted. After reperfusion, an end-to-side anastomosis was performed between the saphenous vein graft and the IVC. Finally, a Roux-en-Y hepaticojejunostomy was carried out. The patient remains well without recurrence 12 months after the last operation.
