ABSTRACT
Background:
The accurate preoperative localization of pulmonary nodules is essential for a successful video-assisted thoracic surgery (VATS). The aim of this research was to clarify the efficacy and safety of CT-guided localization of pulmonary nodules by mixture of methylene blue and medical adhesive.Methods:
Between January 2020 and January 2021, 103 subjects who have received the CT-guidance pulmonary nodules localization operation were included and retrospectively analyzed. The data on efficiency and complications of preoperative localization using medical adhesives mixed with methylene blue mixture were collected and analyzed.Results:
103 patients with 111 localized pulmonary nodules were included, 95 of whom had one nodule and 8 of whom had two nodules. The nodule localization success rate reaches as high as 100 %. The mean diameter of pulmonary nodules was 9.50 ± 3.67 mm. The mean distance of pulmonary nodule and pleural surface was 19.95 ± 14.92 mm. The mean depth of localized adhesive in the lung parenchyma was 18.99 ± 11.62 mm, and the mean time required for localization was 16.98 ± 5.72 min. The average time from the nodule localization to VATS surgery was 16.97 ± 7.34 h. The common complications of localization were minor pulmonary hemorrhage (9.74 %) and mild pneumothorax (15.53 %). Besides, pulmonary hemorrhage was related with depths of medical adhesives and nodules in lung parenchyma (p = 0.018 and 0.002, respectively).Conclusion:
Medical adhesive mixed with methylene blue is safe and effective in pulmonary nodules localization for VATS, and surgeons have flexibility in scheduling the procedure.
