Summary

This summary is machine-generated.

Preoperative 3D models improve lung surgery outcomes. Planning complex video-assisted thoracoscopic surgery (VATS) segmentectomies with 3D models reduces thoracotomy conversions and severe complications, enhancing patient safety.

Area of Science:

Thoracic Surgery
Medical Imaging
Surgical Planning

Background:

Video-assisted thoracoscopic surgery (VATS) segmentectomies are increasingly common.
Accurate preoperative anatomical understanding is crucial for VATS success.
3D reconstruction software offers detailed visualization of lung anatomy.

Purpose of the Study:

To evaluate if 3D models generated from CT scans improve surgical and postoperative outcomes in VATS segmentectomies.
To compare outcomes of VATS segmentectomies performed with and without 3D model-assisted planning.
To assess the impact of 3D models on complication rates and surgical procedures.

Main Methods:

Retrospective analysis of 100 VATS segmentectomies (2018-2023).
Comparison of outcomes between surgeries planned with 3D models versus those without.

surgical outcome

Propensity modeling and inverse probability of treatment weighting (IPTW) for data analysis.

Main Results:

3D model group showed more complex segmentectomies (89% vs 38%) and fewer thoracotomy conversions (P=0.003).
IPTW analysis revealed significantly fewer severe complications (Clavien-Dindo grade III/IV) (OR 0.10, P=0.037).
No Clavien-Dindo grade V complications occurred in the 3D model group.

Conclusions:

Preoperative 3D models significantly reduce thoracotomy conversions and postoperative complications in complex VATS segmentectomies.
3D model-assisted planning enables safe performance of complex anatomical resections.
This technology enhances the safety and efficacy of VATS segmentectomies.
