Objective To investigate the application value of indocyanine green(ICG)in the localization of small pulmonary nodules in video-assisted thoracoscopic surgery(VATS). Methods We retrospectively analyzed the clinical data of 45 patients with small nodules(diameter<1 cm)who received preoperative localization with ICG and underwent VATS wedge resection from October 2020 to February 2021.The data for analysis included patients age,nodule diameter,distance from the parietal pleura,nodule density,success rate of localization,time of localization,incidence of complications,and pathological findings. Results The success rate of localization was 100%.The average nodule size was 6.3 mm,and the nodules were(10±11)mm from the parietal pleura.After localization of 59 nodules,13(22.0%)cases were found to have mild pneumothorax,and 4(6.7%)cases were found to have mild hemorrhage.The success rate of operation was 100%,and 43(72.9%)cases were confirmed adenocarcinoma by postoperative pathology. Conclusion ICG has a high success rate and good safety in the localization of small pulmonary nodules in VATS.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...
