Abstract
Objective To study the application of three-dimensional simulated surgical technique in precise hepatectomy. Methods From July 2009 to February 2010, 16 patients with primary liver cancer underwent preoperative simulated imaging and three-dimensional simulation of liver resection.The 3D extent of simulated hepatectomy and actual hepatectomy was compared and analyzed. Results The shape and the extent of the liver resected were very similar in the simulated and the actual hepatectomies. The mean differences in the length, breadth and depth of the remnant livers were 0. 6118 cm,0. 4490 cm and 0. 3199 cm, respectively. Conclusions Simulation hepatectomy could predict the extent of the actual liver resection, and provided accurate guidance and preoperative planning for precise hepatectomy. Key words: Three-dimensional simulated surgery techniques; Precise hepatectomy; Liver carcinoma
