Interventions/Control_1

Three-dimensional simulation of liver resection is performed with simulation software (OVA, Hitachi Medico; SYNAPSE VINCENT, FUJIFILM) utilizing the data of preoperative enhanced computed tomography (CT). The result of the simulation is transferred to a workstation.

The workstation is carried into the operation room and connected to an ultrasound scanner (Ascendus, Hitachi Aloka Medical) and a tracking device (trakSTAR, Ascension). An electromagnetic transmitter is set on the side of surgical bed. With the system, intraoperative ultrasound image and preoperative CT image on which simulation image is overlaid are displayed side-by-side on a television monitor.
After laparotomy, registration of the navigation system is performed by comparing the images of intraoperative ultrasound and preoperative CT. The resection line indicated by preoperative simulation is marked on the liver surface. The real resection line on the liver surface can be obtained by staining the tumor-baring area with blue dye (indigo carmine), or by dividing both portal vein and hepatic artery of the area. The discrepancy of those resection lines is measured.
In order to check the resection plane, the navigation image is referred during liver resection. After extirpating the liver specimen, its weight and surgical margin are measured. Resected tumor number, time required for resection, total surgical time and amount of blood loss are recorded after the operation.
