Area of Science:

  • Thoracic Surgery
  • Medical Technology
  • Surgical Navigation

Background:

  • Increasing detection of small pulmonary nodules necessitates effective localization techniques.
  • Intraoperative localization of pulmonary nodules presents a significant challenge.

Purpose of the Study:

  • To evaluate the safety and feasibility of a novel augmented reality (AR) navigation technology for intraoperative localization of small pulmonary nodules.

Main Methods:

  • A prospective single-center feasibility study involving ten patients.
  • Utilized a novel AR navigation system with the LungBrella marker.
  • Preoperative CT scans generated 3D models and localization plans uploaded to HoloLens for intraoperative guidance.

Main Results:

  • Localization success rate was 70% (7 out of 10 procedures).
  • In successful cases, the LungBrella marker was placed within a median of 5.8 mm of the nodule.
  • Median localization time was 9.4 minutes; median operation time was 172.9 minutes.
  • No complications were reported during the localization procedures.

Conclusions:

  • Augmented reality navigation-guided pulmonary nodule localization is a safe and feasible technique.
  • This exploratory study supports the potential of AR in improving pulmonary nodule localization.
