This study aims to compare postoperative outcomes of video-assisted thoracoscopic surgery (VATS) and thoracotomy in elderly patients undergoing segmentectomy or lobectomy for primary non-small cell lung cancer (NSCLC). A retrospective analysis was conducted on 129 patients aged 70 years or older who underwent anatomical lung resection (segmentectomy or lobectomy) for NSCLC between January 2016 and June 2021. Patients were divided into two groups based on surgical approach: VATS and thoracotomy. Demographics, tumor characteristics, postoperative complications, chest drainage duration, hospital stay, and short- and mid-term mortality rates were analyzed and compared. The mean age of patients was 73.5 ± 3.2 years, with 55% undergoing surgery via VATS. The VATS group had significantly shorter chest drainage duration (median 4 vs. 6 days, p < 0.001) and hospital stay (median 6 vs. 7 days, p < 0.001). Minor complications were more common in the thoracotomy group (p = 0.022), while no significant differences were found in major complications (p = 0.888). Thirty-day, ninety-day, one-year, and in-hospital mortality rates showed no statistically significant differences between groups. Both VATS and thoracotomy are viable surgical options for elderly NSCLC patients, with similar mortality and major morbidity rates. However, VATS provides advantages in terms of reduced chest drainage duration and shorter hospitalization. Surgical approach should be individualized, taking into account patient characteristics and surgical risk.
