科学领域:

  • 肝胆道手术 肝胆道手术
  • 医疗成像医学成像
  • 手术规划 手术规划

背景情况:

  • 复杂的肝脏手术的手术前规划依赖于二维成像 (CT/MRI),这有局限性.
  • 数字3D肝脏模型 (3DL-RL) 显示出增强决策的潜力,但缺乏多中心证据来证明它们的影响和外科医生变异性.

研究的目的:

  • 评估数字3D肝脏模型 (3DL-RL) 对复杂肝脏手术术前手术规划的影响.
  • 评估与3DL-RL和没有3DL-RL的规划决策中的外科医生间的变异性.

主要方法:

  • 这是一项多中心的,基于病例的调查,涉及挪威五个中心的10名HPB外科医生.
  • 九个匿名肝脏手术病例进行了两次审查:首先仅使用CT/MRI,然后使用CT/MRI加3DL-RL.
  • 统计分析包括Krippendorff的α,Fleiss的 κ,并配对t测试来比较计划轮班和协议.

主要成果:

  • 3DL-RL的使用导致了手术计划的显著转变 (Wilcoxon p=0.006).
  • 在75%的病例中,瘤数量发生了变化,在64%的病例中,手术计划得到了修改.
  • 常见的计划修改包括护体细胞节约策略 (20%),模式切换 (10.9%) 和扩展切除 (7.3%).
  • 关于二进制计划的外科医生间的总体共识仍然很低,但3DL-RL (α=0.664) 的解剖学共识有所改善.

结论:

  • 数字3D肝脏模型有意义地影响复杂肝脏手术的手术前规划,促进有针对性的改变和护体细胞节约方法.
  • 尽管有了改善的解剖学协议,但持续的外科医生间变异性强调了精密外科手术的个性化性质.
  • 建议进一步进行前性,结果相关的研究,并整合ML辅助的工作流程,以确认临床和经济效益.
