背景技术背景：本研究的目的是评估是否三维（3D）模拟软件是适用于解剖肝段切除术和subsegmentectomy.METHODS：83例连续进行解剖肝段切除术或subsegmentectomy使用的穿刺方法进行了前瞻性研究。所有患者术前均接受了三维模拟分析（SA），以规划手术程序。结果：完成3DSA所需时间为18.3 ± 0.7min，完成3DSA所需时间为18.3 ± 0.7min。29例患者（35%）的三维SA建议切除多个节段或亚节段。它还有助于补充26名患者（31%）的切除线，这些患者在肝脏表面缺乏粗染色区域。3D SA计算的节段或亚节段体积与实际切除标本的体积相关（R-2 = .9942，P < .01）。边界肝静脉清楚地暴露在71例（86%），根据完成图纸3D SA。结论：三维SA显示准确的完成图纸，并协助肝外科医生在规划和执行解剖段切除术和亚段切除术。(C)2013 Elsevier Inc.

BACKGROUND: The aim of this study was to evaluate whether 3-dimensional (3D) simulation software is applicable to and useful for anatomic liver segmentectomy and subsegmentectomy.METHODS: A prospective study of 83 consecutive patients who underwent anatomic segmentectomy or subsegmentectomy using the puncture method was performed. All patients underwent 3D simulation analysis (SA) preoperatively for planning operative procedures. The clinical information acquired by 3D SA and the consistency of virtual and real hepatectomy were evaluated.RESULTS: The time needed for completing 3D SA was 18.3 +/- .7 minutes. Three-dimensional SA proposed resection of multiple segments or subsegments in 29 patients (35%). It also helped complement the resection line in 26 patients (31%) who lacked a bold staining area on the liver surface. The volume of segment or subsegment calculated by 3D SA was correlated with the actual resected specimen (R-2 = .9942, P < .01). The bordering hepatic veins were clearly exposed in 71 patients (86%), in accordance with completed drawings by 3D SA.CONCLUSIONS: Three-dimensional SA showed accurate completed drawings and assisted liver surgeons in planning and executing anatomic segmentectomy and subsegmentectomy.
