| Objective:Liver volume has become one of the important indexes to evaluate the liver reserve function,and the preoperative accurate volume measurement is very important for the safe implementation of complex hepatectomy.To investigate the accuracy of liver volume measurement in patients with primary hepatocellular carcinoma by using the3D+medical imaging visualization processing system.Methods:30 patients who clinical diagnosed as primary hepatocellular carcinoma and underwent surgical resection before preoperative assessment were selected from January 2016 to November 2016.Preoperative thin-slice CT images were transferred into the 3D+ medical imaging visualization processing system for hepatic volume measurement,the predictive resection volume were measured and compared and statistically analyzed with that of intraoperative specimen according to water measurement method.Results:30 patients had complete resection of tumor,30 patients had complete resection of tumor,the average volume of the 3D software to calculate the predictive resection volume for(408.84 ± 177.07)ml,the intraoperative specimen of the water test measured the average volume(399.95 ± 176.15)ml,the difference was not statisticallysignificant(t=1.502,P=0.144,> 0.05),and the average percentage error(PE)was6.21%(6.21 ± 4.73).Pearson correlation analysis was used to analyze the predictive hepatic volume and the surgical specimen,the correlation coefficient(r)=0.983(P<0.05).The results showed that there was significant correlation between them.Conclusion:Through this study can find a more simple and accurate measurement of liver volume,clinical application for the accurate determination of liver volume,the evaluation of liver reserve function and the implementation of complex liver resection provide the basis for precise liver resection guidance. |
