ABSTRACT
<p><b>OBJECTIVE</b>Video-assisted thoracoscopic surgery (VATS) provides a minimally invasive approach to resect small solitary pulmonary nodules (SSPN). The aim of this study is to evaluate the efficacy and safety of preoperative CT-guided hookwire localization for SSPN in VATS.</p><p><b>METHODS</b>Hookwire was used to localize 26 SSPN under CT guidance in 24 patients (14 male, 10 female, age range 21-61 years, mean 52.3 years), preoperatively, and wedge resection was performed through VATS. The lesion size, distance from the lesion to parietal pleura, the time of localization and complications were evaluated.</p><p><b>RESULTS</b>All the 26 pulmonary nodules were preoperatively detected and localized with hookwire under CT-guidance. The mean lesion size was 10.05 +/- 3.08 mm in diameter, and the mean distance from lesion to parietal pleura was 10.09 +/- 2.62 mm. The mean localization time was 20.18 +/- 7.16 min, and then the nodules were removed by VATS within 18 +/- 6.65 min. The major complication of CT-guided hookwire localization was mild pneumothorax in 6 patients (25.0%), but no one needed chest tube drainage. The dislodgment of hookwire was found in only one patient (4.2%) during the operation, but the lesion was still successfully resected under VATS. Of those patients, 8 were confirmed to have a primary NSCLC by rapid pathologic diagnosis during VATS wedge resection, and then VATS lobectomies were performed.</p><p><b>CONCLUSION</b>The preoperative CT-guided hookwire localization for small solitary pulmonary nodules is an effective and safe technique to assist VATS resection of the nodules.</p>
