Abstract
BACKGROUND: The aim of this study was to compare the perioperative outcome of patients receiving anatomic segmentectomy either by open surgery or video-assisted thoracoscopic surgery (VATS). To assess the short-term morbidity of the procedure itself, lung cancer patients in all stages as well as patients with pulmonary metastases and benign lesions scheduled for segmental resection were enrolled in this study. METHODS: A retrospective analysis of prospectively collected data on 445 consecutive patients that underwent segmentectomy either by VATS (n=233) or thoracotomy (n=212) was performed. A propensity-matched analysis was conducted based on age, gender, smoking history, histology, tumor size, forced expiratory volume in 1 second (FEV1) and history of previous pulmonary resections. The matched sample included two groups of 140 patients each. RESULTS: Both study groups were comparable with respect to age, gender, smoking history, diagnosis, tumor size, pulmonary function and history of previous pulmonary resections. VATS segmentectomy was associated with decreased length of stay (7.4 vs. 9.5 days, P<0.001), drainage treatment time (4.7 vs. 5.9 days, P=0.012) and severe postoperative complications (1.4% vs. 7.1%, P=0.018). CONCLUSIONS: VATS segmentectomy is safe and effective for the treatment of benign and malignant pulmonary lesions. Compared with open thoracotomy, it is associated with shorter hospitalization time and decreased number of severe complications. The preservation of functional lung tissue, combined with a minimally invasive approach, make VATS segmentectomy highly suitable for patients with reduced pulmonary function or severe comorbidities.
