cholangiocarcinoma.Methods The clinical data of 15 patients with complex hilar cholangiocarcinoma who were admitted to the Chinese PLA General Hospital from January 2008 to December 2009 were retrospectively analyzed.Based on triple-phase contrast-enhanced computed tomography inages,a computer-assisted operative planning system was used to evaluate the anatomic relationship between the tumor and its adjacent vessels,liver volume,operative feasibility,and the potential surgical approaches.The accuracy of three-dimensional reconstruction was tested by comparison to actual intraoperative findings.The correlation between actual liver resection volumes and predicted liver resection volumes was analyzed by calculating a Pearson correlation coefficient.Differences in liver volumes calculated by two-dimensional techniques versus three-dimensional reconstruction were analyzed using the paired t test,and the error rate was compared using the chi-squarc test.
