We discussed the diagnostic and treatment value and clinical significance of computer assisted surgery system (Higemi) in precision surgeries for @entity96 . A total of 21 pediatric cases receiving hepatectomy for @entity5 in the portal vein and giant @entity96 from June 2012 to January 2015 were analyzed. Higemi was used for 3-dimensional (3D) reconstruction of thin-slice CT images and surgical planning. @entity5 were precisely located and blood vessel neighborhood was determined so as to evaluate surgical feasibility. In addition, pathological classification, surgical time, intraoperative @entity190 , transfusion rate and complications were predicted. After 3D reconstruction using Higemi, the neighboring relationship of @entity5 with blood vessels and the running direction of the blood vessels were clearly visualized. Of 21 cases, 10 cases had @entity5 located in the left lobe, 5 cases in the right lobe, 3 cases showing involvement of right trilobes, and 3 cases in the middle lobe. Lobes exceeding one third of the total liver volume were resected in 18 cases. Postoperative pathological examination indicated 10 cases of @entity4177 , 3 cases of @entity157 , 3 cases of @entity4607 , 3 cases of @entity8146 , 1 case of @entity44 and 1 case of undifferentiated @entity361 . The surgical time was 90-240 min with an average of 130 min; the medium intraoperative @entity190 was 60 ml and the minimum @entity190 was 3 ml; the transfusion rate was 42.9% (9/21). Surgeries were successful in 20 cases, who were discharged after recovery. However, one case had @entity96 combined with severe @entity3883 and @entity7752 and died of @entity1578 and DIC. 3D reconstruction of CT data using Higemi can clearly visualize the running direction of blood vessels and the neighboring relationship with @entity5 . Higemi can improve the precision and safety of complex hepatectomy.
