Objectives:
The aim of this study was to evaluate the feasibility, accuracy, and safety of computed tomographic (CT)-guided coil localization before video-assisted thoracoscopic surgery.
Methods:
One hundred and eighty-four consecutive patients with 200 pulmonary nodules who underwent CT-guided percutaneous coil localization before thoracoscopic surgery were retrospectively analyzed in this study. Success rate for localization, complication rates, CT findings, and pathological results of the lesions, as well as the data related to surgery were all recorded and analyzed.
Results:
All 184 patients with 200 lesions completed localization and resection. The success rate of the coil localization on lesion baseline was 99.0% (198/200) and 98.9% (182/184) on patient baseline. The number of wedge resection, segmental resection, and lobectomy were 179 (89.5%), 19 (9.5%), and 2 (1.0%), respectively. The malignancy rates in a lesion-based analysis were 83.5% (91.1% in ground-glass nodules, 91.4% in part-solid nodules, and 37.9% in solid nodules). No serious complications occurred in all localization procedures.
Conclusion:
Preoperative CT-guided percutaneous coil localization is a safe and effective method to facilitate high success rates for both wedge and segmental resection for peripheral pulmonary nodules.
