Abstract:
Objective:To investigate the effectiveness and safety of fluorescence thoracoscopy-assisted temporary occlusion of pulmonary arteries and veins during sublobar resection for the treatment of early-stage non-small cell lung cancer (NSCLC).Methods:This is a prospective cohort study. Patients with early-stage NSCLC who underwent fluorescence thoracoscopy-assisted temporary occlusion of pulmonary arteries and veins for sublobar resection in the Department of Thoracic Surgery, Beijing Chaoyang Hospital, Capital Medical University, from January to April 2024 were included. Based on whether the artery or vein was blocked during surgery, the patients were divided into the arterial group and the venous group. The surgical time, intraoperative blood loss, distance from the lesion to the resection margin, and boundary duration were collected and compared between the two groups. Independent sample t test, Mann-Whitney U test, or χ2 test was used to compare the data between the two groups. Results:A total of 64 patients were enrolled. There were 25 males and 39 females, aged (57.3±12.1) years (range: 34 to 80 years). The tumor diameter was (9.8±2.9) mm (range: 5 to 16 mm). The distance between the surgical margin and the lesion was (16.5±3.9) mm (range: 10 to 30 mm) and the surgical time was (61.5±13.9) minutes (range: 30 to 120 minutes). Pathological examination of the surgical specimens showed that all margins met pathological requirements. The chest drainage tube retention time ( M(IQR)) was 2 (1) days (range: 1 to 7 days), and no serious postoperative complications occurred. The boundary duration for the arterial group ( n=23) and venous group ( n=41) was (147.9±22.2) seconds (range: 119 to 188 seconds) and (40.9±8.0) seconds (range: 20 to 60 seconds), respectively ( t=27.935, P<0.01). Conclusion:Fluorescence thoracoscopy-assisted temporary occlusion of pulmonary arteries and veins can effectively and accurately delineate surgical resection boundaries, ensuring sufficient margin width to meet oncological requirements.
