Abstract:
ObjectiveTo investigate the value of a digital three-dimensional reconstruction technique in the treatment of hepatic alveolar echinococcosis (HAE).MethodsThe computed tomography scan data for 13 patients with HAE who were admitted to the First Affiliated Hospital of Xinjiang Medical University from February 2011 to October 2011 were reconstructed and analyzed by a three-dimensional reconstruction system to assess resectability,and to facilitate surgical planning and individualized virtual surgery.The results of preoperative analysis were compared with the results of actual operations.ResultsThe three-dimensional models of the liver were reconstructed successfully,and intrahepatie lesions and vessels were clearly displayed.One patient received an autologous liver transplantation,10 underwent hepatectomy,and 2 received percutaneous transhepatic cholangial drainage.Virtual operation planning was carried out for 11 patients using the three-dimensional reconstruction system.The mean volume of the liver to be resected was predicted to be 920 ml (range,339-2678 ml),and the mean percentage of liver to be resected to the total liver volume was predicted to be 45％ ( range,23％ -68％ ).The mean volume o[ the actual liver resection was 834 ml (range,315-2250 m[),and the mean percentage of actual liver resected to the total liver volume was 42％ (range,22％ -70％ ),which was consistent with the results of preoperative three-dimensional reconstruction.All patients were followed up for 2-8 months,and no severe complications such as liver failure,hemorrhage and bile leakage were detected.ConclusionDigital three-dimen-sional reconstruction is helpful in the diagnosis and treatment of HAE and effectively reduces surgical risks.
