Objective To analyze the effect of indocyanine green (ICG) fluorescence dual-visualization technique on evaluating tumor margins during the thoracoscopic segmentectomy. Methods A total of 36 patients who underwent thoracoscopic anatomical segmentectomy using ICG fluorescence dual-visualization technique in our hospital from December 2020 to June 2021 were retrospectively included. There were 15 males and 21 females aged from 20 to 69 years. The clinical data of the patients were retrospectively analyzed. Results The ICG fluorescence dual-visualization technique clearly showed the position of lung nodules and the plane boundary line between segments during the operation. There was no ICG-related complication. The average operation time was 98.6±21.3 min, and the average intraoperative bleeding amount was 47.1±35.3 mL, the average postoperative drainage tube placement time was 3.3±2.8 d, the average postoperative hospital stay was 5.4±1.8 d, and the average tumor resection distance was 2.6±0.7 cm. There was no perioperative period death, and one patient suffered a persistent postoperative air leak. Conclusion The ICG fluorescence dual-visualization technique is safe and feasible for evaluating the tumor margins during thoracoscopic segmentectomy. It simplifies the surgical procedure, shortens the operation time, ensures sufficient tumor margins, and reserves healthy pulmonary parenchyma to the utmost extent, providing reliable technical support for thoracoscopic anatomical segmentectomy.
