| Objective: In this paper,a total of 35 patients with primary liver cancer in the experimental group and the control group were evaluated before surgery,and the clinical application of three-dimensional visualization technology in preoperative evaluation and prediction of primary liver cancer was discussed,as well as three-dimensional visualization.The clinical application value of technology in liver cancer resection.Methods: A total of 47 liver cancer patients who were admitted to the Department of Hepatobiliary Surgery in our hospital from September 2016 to December 2018 were selected.The enhanced CT/MRI imaging data of all patients were collected and divided into two groups,23 cases in group A,and images of this group of patients The data was reconstructed by three-dimensional visualization technology to obtain three-dimensional visualization images.A total of 18 patients who had undergone preoperative evaluation to determine the operation were used as the experimental group;24 patients in the B group were analyzed by CT/MRI images,and a total of 17 patients were confirmed for surgery as a control group.The experimental group used the three-dimensional visualization system to clarify the position of the tumor and the anatomical relationship between the tumor and the surrounding tissues,evaluate the tumor invasion,for mulate the surgical plan and practice repeatedly in the surgical simulation system.The control group was prepared for the operation according to conventional methods and underwent hepatectomy.Record the operation duration,intraoperative blood loss,preoperative and postoperative laboratory test results,postoperative hospital stay,total cost,and postoperative complications of the experimental group and the control group respectively,and record the simulated pre-resection liver volume of the experimental group And compared with the size of liver lobes measured by postoperative drainage.SPSS23.0 statistical software was used to analyze the data of two groups of patients.Two groups of patient’s age,intraoperative blood loss,duration of operation,preoperative and postoperative result of test,postoperative hospital stay,the length of the total cost of simulations,the drainage volumetric resection volume and the actual comparison and relevant data in the form of x±s said,two groups of comparison results t test was used to P<0.05 was statistically significant.Pearson correlation analysis was used to determine the correlation between the simulated liver volume and the measured liver volume before resection.Results: the relationship between tumor and vasculature can be accurately displayed by the visualization system of 3D visualization technology.The results of the experimental group were(216.39±49.36)min of operation time and(316.67±157.18)ml of intraoperative blood loss,which were significantly lower than those of the control group(297.12±98.64)min and(588.24±351.572)ml,respectively,with statistically significant differences(t=3.04,-2.92,P<0.05).Postoperative ALT,AST,TBil and Alb in the experimental group were(234.36±133.91)U/L,(159.47±69.06)U/L,(18.20±6.58)mol/L,(33.16±6.14)g/L,respectively,which were significantly lower than those in the control group(352.28±166.96)U/L,(354.33±348.10)U/L,(27.73±13.37) mol/L,(28.95±5.89)g/L.The differences were statistically significant(t=-2.31,-2.27,-2.70,2.07).P<0.05).The preoperative virtual hepatectomy volume of the experimental group was(554.81±345.85)ml,compared with the actual intraoperative hepatectomy volume(551.20±340.74)ml,and the Pearson correlation coefficient value was 0.970.The cutting edge of the experimental group was better than that of the control group(positive rates were 5% and 6%,respectively).Conclusion: Three-dimensional visualization technology is significantly better than two-dimensional imaging for the selection of surgical methods,approach,liver volume,and prevention of postoperative complications in patients with liver cancer.There is no significant difference between volume and surgical resection. |
