Anterior transhepatic approach for isolated resection of the caudate lobe of the liver

We have devised a new technique for isolated caudate Lobe resection in which we access the caudate lobe by separating the liver parenchyma along the interlobar plane. The safety and radicality of the procedure were evaluated in five patients: four with hepatocellular carcinoma (HCC) and one with metastatic rectal cancer. All of the tumors were located mainly in the paracaval portion of the caudate lobe. The patients with HCC (three of four) underwent an anatomic caudate lobe resection by identification of the right margin of the caudate lobe. Two patients required red blood cell transfusion, and one showed bile leakage after surgery. All of the patients are alive without recurrence more than 4 years after surgery, except one with rectal carcinoma who developed lung metastases. The anterior transhepatic approach is a safe and potentially curative surgical option for a tumor in the paracaval portion of the caudate lobe.
