Purpose: We analyzed the feasibility and safety of our preliminary surgical approach for total hepatic resection of the right hepatic vein drainage area (THR-RHV) with the aid of three-dimensional computed tomography (3D-CT) guidance. Methods: Clinical findings and 3D-CT volumetry results were investigated in five patients who underwent THR-RHV for a hepatic malignant tumor close to the right hepatic vein (RHV). Results: The mean estimated remnant liver volume after a conventional right lobectomy was 474 ml, whereas that after THR-RHV was 614 ml, indicating that 140 ml (13.8%) of additional liver volume had been preserved by performing THR-RHV. The median operative time, mean ischemic time, and mean blood loss during surgery were 406 min, 51 min, and 587 ml, respectively. Histological examinations confirmed a negative surgical margin in all five patients. The mean liver volume estimated by 3D-CT was 458 ml, whereas the mean actual resected liver volume was 468 g, resulting in a mean error ratio of 3.1%. Conclusions: THR-RHV allowed for a higher remnant liver volume than that after conventional right lobectomy of the liver, and proved feasible with acceptable perioperative results. This technique thus promotes both safety and curability for patients with a tumor close to the RHV.
