Clinical Application Of3D Reconstruction Technique On Precise Hepatectomy For Primary Liver Cancer

Objective: To evaluate the clinical value of three-dimensional reconstructiontechnique in precise hepatectomy for primary liver cancer. Method: The liver3dreconstruction system(IQQA-liver) was used to reconstruct CT data of41patients withprimary liver cancer in our hospital from January2011to January2012. Volume of totalliver volume, tumor volume, predicted resection volume and the remnant liver volumewere measured by the software, the data of volume was compared with that werecalculated based on the2-dimensional imaging and actual operation. Results: All of the3D models of liver were reconstructed successfully, the average external volume of liverwas1600±486cm~3; the volume of tumor was292±247cm~3; the predicted resection volumewas577±288cm~3; the volume percentage of remnant liver was64.80±11.24%.The actualaverage volume of remnant liver in operation was580±285cm~3. The volume calculatedbased on the2D imaging was similar to that calculated based on the3D imaging(t=1.835、1.956, P＞0.05). There was a positive correlation between the predicted resection volumeand the resected liver volume(r=0.991, P＜0.05). The surgical methods of patients inactual operation were similar to that in the virtual resection.Conclusion: The3Dreconstruction of liver benefits a lot to preoperative assessment,and have importantsignificance in precise hepatectomy for primary liver cancer.
