Abstract:
Objective To investigate the clinical value of computer-assisted operation planning system for precise hepatectomy.Methods The clinical data of 45 patients who had undergone precise hepatectomy at General Hospital of PLA from November 2006 to November 2009 were retrospectively analyzed.The 3-dimensional imaging of liver was constructed by computer-assisted operation planning system,and the anatomic relationship between hepatic vasculature and tumor Was analyzed.Volume of hepatic segments,total liver volume,tumor volume,predicted resection volume and the remnant liver volume were calculated before operation.Virtual liver resection was performed in order to select the best operative procedure.The predicted resection volume Was compared with the hepatic segment resected.All data were analyzed by t test,Pearson rank correlation analysis and chi-square test.Results The predicted resection volume calculated based on the 2-dimensional imaging was similar to that calculated based on the 3-dimensional imaging(t=2.125,P>0.05).The three-grade branches of the hepatic artery,portal vein and hepatic vein were clearly shown in the computer-assisted operation planning system.The anatomic relationship between tumor and adjacent vessels was quantitatively analyzed.There was a positive correlation between the predicted resection volume and the resected liver volume(r=0.999,P<0.05),and the error rate Was 5.1%.All patients received anatomical hepatectomy,and the incidence of postoperative complications was 20%(9/45).No liver failure or perioperative mortality was observed.Conclusion Computer-assisted operation planning system may facilitate and promote precise hepatectomy.
