Abstract

Objective: Assess the efficiency and safety of computed tomography (CT)-guided hook-wire localization prior to video-assisted thoracoscopic surgery (VATS) at the National Lung Hospital in 2023.

Method: 19 patients were examined and treated at the National Lung Hospital from August 2023 to March 2024, with the diagnosis results of lung nodules on computed tomography scans and were localized of pulmonary nodules before VATS. Method: Case-series study.

Results: 94.74% of patients were successfully located lung nodules before surgery. The average age was 51.74 ± 10.96. The male-to-female ratio was approximately 1:2. The mean diameter of lung nodules was 13.32 ± 5.34 mm. Nodules were predominantly ground-glass nodules (GGNs) and part-solid GGNs, accounting for 78.9%. The mean distance from the nodules to the pleural surface was 10.95 ± 8.28 mm. The mean procedure time of localization was 5.74 ± 2.8 minutes. Common complications included parenchymal hemorrhage (47.4%), pneumothorax (10.5%), and hemothorax (10.5%), with no severe complications observed. Hook-wire dislodgement occurred in one patient (5.3%). All patients underwent completed resection of lung nodules and received frozen section intraoperatively. There were no cases requiring thoracotomy.

Conclusions: Preoperative percutaneous hook-wire localization is an effective and safe technique that facilitates video-assisted thoracoscopic surgery by accurately localizing small and deep pulmonary nodules.
