Abstract: Objective To investigate the value of preoperative CT?guided localization and intraoperative dyestuff?clip marking in VATS pulmonary nodule excision. Methods A total of 89 patients from August 2015 to May 2018 were registered，who received treatment in the department of thoracic surgery of The First People′s Hospital of Foshan. There were 98 pulmonary nodules used CT guiding localization before operation ，and used the methylene blueclip marking the pleural surface of pulmonary nodules during the operation. Then we performed the vedio assist thoracoscopic wedge resection. Results Of the 98 nodules ，85 cases（87%）were were successfully localized. The other 13 cases failed to locate because of their proximity to the mediastinal surface. All the 85 cases received vedio?assist thoracoscopic wedge resection successfully. There were no severe complications occurred during the operation，and no one transfered to open thoracotomy. All patients were histologically confirmed during the operation. Conclusion VATS by CT?guided localization before operation and dyestuff?clip marking intraoperatively is a viable safe procedure that meets oncological criteria for lung nodules surgery. In our experience， VATS is currently to be considered ideally indicated for pulmonary nodule surgery.
