Navigated bronchoscopy uses virtual 3-dimensional lung model visualizations created from preoperative computed tomography images often in synchronization with the video bronchoscope to guide a tool to peripheral lesions. Navigated bronchoscopy has developed fast since the introduction of virtual bronchoscopy with integrated electromagnetic sensors in the late 1990s. The purposes of the review are to give an overview and update of the technological components of navigated bronchoscopy, an assessment of its clinical usefulness, and a brief assessment of the commercial platforms for navigated bronchoscopy.
We performed a literature search with relevant keywords to navigation and bronchoscopy and iterated on the reference lists of relevant papers, with emphasis on the last 5 years.
The paper presents an overview of the components necessary for performing navigated bronchoscopy, assessment of the diagnostic accuracy of different approaches, and an analysis of the commercial systems. We were able to identify 4 commercial platforms and 9 research and development groups with considerable activity in the field. Finally, on the basis of our findings and our own experience, we provide a discussion on navigated bronchoscopy with focus on the next steps of development.
The literature review showed that the peripheral diagnostic accuracy has improved using navigated bronchoscopy compared with traditional bronchoscopy. We believe that there is room for improvement in the diagnostic success rate by further refinement of methods, approaches, and tools used in navigated bronchoscopy.
导航支气管镜检查利用术前计算机断层扫描图像创建的虚拟三维肺部模型可视化，通常与视频支气管镜同步，以引导工具到达周围病变部位。自20世纪90年代末引入集成电磁传感器的虚拟支气管镜以来，导航支气管镜检查发展迅速。本综述的目的是概述和更新导航支气管镜检查的技术组件，评估其临床实用性，并简要评估导航支气管镜检查的商业平台。
我们使用与导航和支气管镜检查相关的关键词进行文献检索，并在相关论文的参考文献列表上进行迭代，重点关注过去5年的文献。
本文概述了进行导航支气管镜检查所需的组件，评估了不同方法的诊断准确性，并分析了商业系统。我们能够识别出4个商业平台和9个在该领域有大量活动的研发团队。最后，基于我们的研究结果和自身经验，我们对导航支气管镜检查进行了讨论，重点关注其下一步的发展。
文献综述表明，与传统支气管镜检查相比，使用导航支气管镜检查提高了周围病变的诊断准确性。我们认为，通过进一步改进导航支气管镜检查中使用的方法、途径和工具，诊断成功率仍有提高的空间。
