Abstract:
ObjectiveTo evaluate the feasibility of a three-dimensional (3 D) operation planning system for precise hepatectomy in patients with giant hcpatocellular carcinoma (HCC).MethodsThe clinical data of 34 patients with giant HCC who received precise hepatectomy at the First Affiliated Hospital of Sun Yat-sen University from May 2009 to May 2011 were retrospectively analyzed.Preoperative evaluation was done based on the computed tomography data,and the resection margin and the volume of resectcd liver were calculated using simulation.The predicted resected liver volume and resection margins were compared with the results of the actual operations.All data were analyzed using the t test,and the correlation between predicted and the actual values was analyzed by calculating Pearson correlation coefficients.Results Hepatic and tumor tissues and the hepatic vessels were reconstructed three-dimensionally using the 3D preoperative simulation software.The volume of simulated resected liver and the length of resection margin were ( 2112 ± 1550 ) ml and ( 12 ± 6) mm,respectively,while the volume of actual resected liver and the length of resection margin were (2031 ± 1411 )ml and ( 12 ± 6)mm,respectively.The predicted and the actual values were statistically correlated ( r =0.961,0.923,P ＜ 0.05 ).There was no significant difference between the predicted and the actual values ( t =1.549,1.143,P ＞ 0.05 ).All patients received precise hepatectomy,and no hepatic failure or death was observed. Conclusion The 3D operation planning system can accurately evaluate the condition of the liver and simulate hepatectomy,and could contribute to safer and more curative precise hepatectomy in patients with giant HCC.
