Abstract：【Objective】To investigate the effect of three-dimensional reconstruction on minimally invasive precise hepatectomy operation for right hepatic hepatectomy. 【Methods】The clinical data of 64 patients with right hepatectomy were selected and divided into observation group (n=38, used before operation) and control group (n=26, unused before operation). The operative time, the intraoperative blood loss, the blocking time of the hepatic gate, the actual resection of the liver volume, the postoperative hospital stay and the postoperative complications were recorded.【Results】 The operative time, intraoperative bleeding volume, hepatic portal occlusion time and hospitalization time in the observation group were significantly lower than those in the control group (P<0.05).The actual liver resected liver volume of the observation group was slightly smaller than that of the preresectomized liver, and the difference was not statistically significant (P>0.05).The results of linear correlation analysis showed that there was a significant correlation between the volume of preresectomized liver and the actual volume of liver resected (r=0.925,P<0.01).There were 3 cases in the observation group and 2 cases in the control group which developed peritoneal effusion after operation and were cured by drainage.No CO2 embolism, biliary fistula, bleeding and other complications occurred in both groups.【Conclusion】 Three-dimensional reconstruction and simulated hepatectomy system can reduce the time of laparoscopic hepatectomy, the amount of intraoperative bleeding, the time of hepatic hilus occlusion and postoperative hospitalization time, which can accurately predict the tumor volume. It has a certain auxiliary effect in laparoscopic hepatectomy.
