Abstract:
Objective To investigate the value of three-dimensional visualization system in the treatment of hilar cholangiocarcinoma.Methods The clinical data of 10 patients with hilar cholangiocarcinoma who were admitted to Chenggong Hospital of Xiamen University from January 2012 to September 2012 were retrospectively analyzed.The two-dimensional computed tomography images were converted to three-dimensional images with the three-dimensional visualization system,and then the volume of liver and tumor size,volume of liver to be resected,remnant liver volume were measured.Surgical procedure was planned based on the three-dimensional images,and the difference between the actual and planned surgical procedures was analyzed.The correlation between actual liver resection volume and predicted liver resection volume was analyzed by calculating the Pearson correlation coefficient.Results The mean liver volume,tumor size,predicted liver resection volume and remnant liver volume of the 10 patients detected by the three-dimensional visualization system were (1496 ± 162) ml,(67 ± 18) ml,(335 ± 241)ml and (1140 ± 197)ml,respectively.The average error rate of predicted liver resection volume was 6.4％.Surgical plan was made in accordance with the principle of curative hepatectomy,including 4 cases of left semihepatectomy,2 cases of right semihepatectomy,3 cases of partial liver resection and 1 case of palliative liver resection.The coincidence rate between the planned and actual surgical procedures was 9/10.R0 resection was performed on 7 patients,R1 resection on 1 patient and palliative resection on 2 patients.One patient received restrictive portal vein arterialization.Preoperative evaluation of the anatomy of blood vessels,bile ducts and tumors based on three-dimensional images was confirmed with operative findings.The accuracy of tumor typing by the three-dimensional visualization system was 8/10.The actual liver resection volume was (325 ± 258) ml,which was positively correlated with the predicted liver resection volume (r =0.902,P ＜ 0.05).Conclusion The three-dimensional visualization system is helpful in the treatment of hilar cholangiocarcinoma.
