Abstract Objective To evaluate the efficacy and safety of CT-guided Hook-wire localization in the treatment of synchronous multiple primary lung cancer (SMPLC) before video-assisted thoracoscopic surgery (VATS). Methods From February 2011 to December 2016, 47 patients with SMPLC admitted to the thoracic surgery department of Jiangyin People′s Hospital Affiliated to Southeast University were retrospectively analyzed. All patients were treated with Hook-wire localization needle under CT guidance, and VATS was performed to remove the lesions. Further surgical methods were determined according to the frozen pathological results during the operation. Positioning accuracy, the success rate of VATS lung lesion resection surgery, postoperative complications and other indicators were calculated. Results Among 47 patients, there were 19 patients with unilateral SMPLC and 28 with bilateral SMPLC. All resections of lesions which guided by the inserted Hook-wire were successfully performed by VATS (success rate was 100%). The mean procedure time for the CT-guided Hook-wire localization was (34.98±5.95) min. The major complication of CT-guided Hook-wire localization was slight pneumothorax (lung compression<20%) in 7 patients(14.9%), no one needed chest tube drainage. Moderate pneumothora (lung compression ≥20%) were observed in 4 patients(8.6%). Contralateral pneumothorax occurred during operation in 2 patients (4.3%). Two patients (4.3%) had minimal hemothorax (≤50 mL) during VATS. One patient (2.1%) underwent additional wedge resection by VATS during the same procedure because no lesion was identified in the surgical specimen. Conversion thoracotomy were required in 2 patients (4.3%) for pleural adhesions. None of Hook-wires dislodged or displaced during the transport to the surgical suite. Conclusion Preoperative CT-guided Hook-wire localization is accurate, safe and has less complications. It is of great clinical value in the diagnosis and treatment of SMPLC for VATS.
