Summary
A novel coil localization technique significantly improved the success rate for preoperative pulmonary nodule localization compared to conventional methods. This new approach demonstrated higher efficacy while maintaining a comparable safety profile for patients undergoing VATS.
Area of Science:
- Thoracic Surgery
- Diagnostic Imaging
- Interventional Pulmonology
Background:
- Computed tomography (CT)-guided coil localization is standard for preoperative pulmonary nodule (PN) assessment.
- This study compares conventional CT-guidance with a novel coil localization technique for PNs.
Purpose of the Study:
- To evaluate the efficacy and safety of a novel coil localization technique versus conventional CT-guided coil localization for PNs.
- To compare localization success rates and video-assisted thoracoscopic surgery (VATS)-related outcomes between the two techniques.
Main Methods:
- Retrospective study of 83 patients with PNs undergoing either conventional (n=41) or novel (n=42) coil localization before VATS resection.
- Comparison of localization success rates, procedure duration, and VATS-related outcomes including pneumothorax and hemorrhage.
Main Results:
- The novel coil group achieved a significantly higher localization success rate (100%) than the conventional group (87.8%, P=0.026).
- Localization and VATS procedure durations were comparable between groups.
- Rates of pneumothorax and lung hemorrhage were similar, with no significant differences in VATS limited resection or final pathological diagnoses.
Conclusions:
- The novel coil localization technique is more effective for preoperative PN localization than the conventional approach.
- The novel technique offers a similar safety profile to conventional methods, making it a viable alternative for PN assessment.
