Summary
Three-dimensional (3D) imaging navigation using an iPad improves the safety and security of lung segmentectomy procedures. This technology aids surgeons in performing complex anatomical resections with enhanced precision.
Area of Science:
- Thoracic Surgery
- Medical Imaging
- Surgical Navigation
Background:
- Anatomical lung segmentectomies are increasingly common but technically challenging.
- Minimally invasive surgical techniques are crucial for improving patient outcomes.
Purpose of the Study:
- To evaluate the efficacy of intra-operative three-dimensional (3D) computed tomography (CT) navigation using an iPad for lung segmentectomy.
- To assess the safety and feasibility of this novel surgical approach.
Main Methods:
- Fourteen patients underwent anatomical segmentectomy for lung cancer or metastases.
- 3D CT images were reconstructed and transferred to an iPad for intra-operative analysis.
- DICOM image viewer software was utilized on the iPad for surgical guidance.
Main Results:
- All fourteen segmentectomies were performed successfully.
- No major intra-operative or post-operative complications were observed.
- Pathological examination confirmed no positive surgical margins in any patient.
Conclusions:
- Intra-operative 3D CT navigation via an iPad facilitates safe and secure lung segmentectomies.
- This technology offers a valuable tool for enhancing precision in complex thoracic surgeries.
