Abstract:
To resect a small liver tumor located in the paracaval portion, we adopted transhepatic enucleation, i.e. enucleation of the tumor from the transected plane along the main portal fissure. In contrast to caudate lobectomy, this procedure can save dissection around the liver and vena cava, which would increase operation time and blood loss especially in repeat surgery after removal of Couinaud's segment VII or the right lateral sector. It can also minimize the liver parenchymal volume to be resected. The transhepatic enucleation would be a safe and recommendable surgical technique for a small paracaval tumor in repeat resection and/or in patients with poor liver functional reserve.
