Summary
Brief summary (as posted)
Preoperative three-dimensional (3D) lung reconstructions can reduce intraoperative blood loss, conversion rate, and operation duration. Commercial products predominantly provide these 3D reconstructions, hence the aim of this study was to assess the usability and performance of preoperative 3D lung reconstructions created with open-source software.

Arms and outcomes
Arms (1)
- label
- Preoperative 3D lung reconstruction
- description
- Patients who were planned for an anatomical lung resection with preoperative 3D lung reconstruction from CT images
Primary outcomes (1)
- measure
- System Usability Score
- timeFrame
- Single-point evaluation after surgery (at day 0)
- description
- System Usability Score Questionnaire. This questionnaire includes 10 statements rated from 1 (strongly disagree) to 5 (strongly agree). The even-numbered questions contributed to the scale position 5 minus the scale position, while the odd-numbered questions contributed to the scale position minus 1. The final score was calculated by the sum of the even and uneven-numbered questions, multiplied by 2.5. The minimum system usability score is 0 and the maximum is 100. A system usability score above 68 is considered above average.
Secondary outcomes (5)
- measure
- Segmental lung nodule location
- timeFrame
- Baseline and during surgery (at day 0)
