The Application Value Of Three-dimensional Simulated Surgery Techniques To Precise Hepatectomy

Three-dimensional visualization hepatic simulation not only presents a clear and accurate anatomical structure of the whole liver, intrahepatic pipeline distribution system, exact location of the tumor, etc., but can be reproduced in three-dimensional visualization. All of these can afford more intuitive observation of the lesion characteristics. In addition, the capacity analysis and hepatectomy simulation can be used in this 3D hepatic simulation.There are extremely important application value in completely resection of target lesions, minimum the liver tissue damage and bleeding, guaranteed the integrity of the remaining liver structure and function of compensation.Objective:To evaluate the application value of three-dimensional simulated surgery techniques in precise hepatectomy.Methods:To July 2009-February 2010, the Court of 16 cases with surgical treatment of primary liver cancer patients had preoperative simulated imaging and three-dimensional simulation of surgical operations, and then the edges of simulated hepatectomy and actual hepatectomy in 3D lines will be underwent the statistics and correlation analysis.Results:Simulation of liver resection surgery and actual surgery is very similar to the organization, not only significantly cut the edge of relevance, but did not have statistically significant.1,The difference between the average length of simulation and the actual hepatectomy:X-axis:0.6118cm (r=0.958;p=0.305);Y-axis:0.4490cm (r=0.958; p=0.190);Z-axis:0.3199cm (r=0.975; p=0.341);Conclusions:Simulation procedure can predict the range of the target lesion resection, and provide accurate guidance and preoperative planning for precise hepatectomy.
