Purpose : The purpose of this study was to evaluate the efficacy and safety of Electromagnetic navigation bronchoscopy (ENB)-guided localization with dye-marking for thoracoscopic resection of small pulmonary nodules.

Methods : Consecutive 133 patients who underwent ENB-guided dye-marking followed by thoracoscopic resection of small pulmonary nodules from July 2016 to November 2019 were reviewed retrospectively. Efficacies were evaluated by the success rates of marking (visible dye-mark), localization (localization only aided by dye-mark) and resection (presence of nodule confirmed pathologically). Safety was evaluated by the rate of ENB-related complications.

Results : ENB-guided dye-marking was performed on 160 lesions in 133 patients. Twenty-two (16.5%) patients had multiple nodules. Total number of dye-marking was 231 median number was 2 (1-4). Radiologic characteristics were pure ground glass nodule in 104 (65%), part-solid nodule in 48 (30%) and solid nodule in 9 (5%) nodules. Mean size of nodules was 9.4 ± 4.9 (3-26) mm and mean depth from visceral pleura was 10.1±7.4 (0-35) mm. Mean ENB time was 30±15.1 (5-78) minutes. No ENB-related complication occurred. The success rate of dye-marking was 93.5% (216/231) and the success rate of localization was 95.6% (153/160). The success rate of resection was 99.4%. Diagnostic surgery were wedge resection in 129 (80.6%) and segmentectomy in 30 (18.7%) nodules. Histology of nodules were adenocarcinoma in 62 (38.7%), minimal invasive adenocarcinoma in 46 (28.7%), atypical adenomatous hyperplasia in 16 (10%), metastatic carcinoma in 7 (4.3%) and benign in 20 (12.5%) nodules.

Conclusion : ENB-guided dye-marking was an effective and safe localization modality for thoracoscopic resection of small pulmonary nodules.
