Impact of patient-specific three-dimensional reconstruction on surgical planning and perioperative outcomes in early-stage lung cancer: a randomised clinical trial - Report - MDSpire
Clinical Report: Effect of Customized 3D Reconstruction on Surgical Strategy
Overview
This randomized controlled trial demonstrates that preoperative 3D reconstruction significantly reduces key-phase operative time and unexpected intraoperative events in early-stage lung cancer surgeries.
Background
Accurate identification of bronchial and vascular anatomy is crucial for successful segmentectomy in early-stage non-small cell lung cancer (NSCLC). Traditional 2D imaging often fails to provide the necessary anatomical clarity, which can lead to complications during surgery. The integration of 3D reconstruction techniques may offer improved visualization and operational efficiency.

Key Findings
3D reconstruction reduced key-phase operative time compared to 2D CT (75.78 vs 95.74 min, P < 0.001).
Fewer unexpected intraoperative events occurred in the 3D group (6.9% vs 30.6%, P = 0.001).
The likelihood of achieving adequate surgical margins was higher in the 3D group (84.7% vs 66.7%, P = 0.016).
Surgeons reported better preoperative anatomical visualization and greater intraoperative confidence with 3D reconstruction (P < 0.001).
Reduction in key-phase operative time was more pronounced among less experienced surgeons (P = 0.018).
Clinical Implications
The use of 3D reconstruction in surgical planning for early-stage NSCLC may enhance surgical outcomes by reducing operative time and complications.
Conclusion
Preoperative 3D reconstruction is associated with improved surgical efficiency and outcomes in early-stage lung cancer segmentectomy.
