ABSTRACT
<p><b>OBJECTIVE</b>To study the clinical application of digital medical in the operation on primary liver cancer.</p><p><b>METHODS</b>The patients (n=11) with primary hepatic carcinoma treated between February and July 2008, including 9 cases of hepatocellular carcinoma, 2 cases of cholangiocellular carcinoma, were scanned using 64 slices helicon computerized tomography (CT) and the datasets was collected. Segment and three-dimensional (3D) reconstruction of the CT image was carried out by the medical image processing system which was developed. And the 3D moulds were imported to the FreeForm Modeling System for smoothing. Then the hepatectomy in treatment of hepatoma and implanting of catheter were simulated with the force-feedback equipment (PHANToM). Finally, 3D models and results of simulation surgery were used for choosing mode of operation and comparing with the findings during the operation.</p><p><b>RESULTS</b>The reconstructed models were true to life, and their spatial disposition and correlation were shown clearly; Blood supply of primary liver cancer could be seen easily. In the simulation surgery system, the process of virtual partial hepatectomy and implanting of catheter using simulation scalpel and catheter on 3D moulds with PHANToM was consistent with the clinical course of surgery. Life-like could be felt and power feeling can be touched during simulation operation.</p><p><b>CONCLUSIONS</b>Digital medical benefited knowing the relationship between primary liver cancer and the intrahepatic pipe. It gave an advantage to complete primary liver cancer resection with more liver volume remained. It can improve the surgical effect and decrease the surgical risk and reduce the complication through demonstrating visualized operation before surgery.</p>
