Abstract
Video-assisted thoracoscopic surgery may be associated with less morbidity than open lobectomy or segmentectomy, but some studies have questioned the benefit of thoracoscopic surgery. This study aimed to determine trends and factors associated with patient's likelihood of undergoing thoracoscopic lobectomy or segmentectomy and to compare outcomes with each approach. This retrospective study included adult patients undergoing pulmonary lobectomy or segmentectomy from the American College of Surgeons National Surgical Quality Improvement Project from 2007 to 2015 (n = 14,717). Logistic regression analysis was conducted to determine the association of patient demographics, clinical characteristics, and surgeon specialty with thoracoscopic lobectomy or segmentectomy. Propensity score matching was performed to evaluate outcomes for thoracoscopic and open lobectomy or segmentectomy. Use of thoracoscopic lobectomy or segmentectomy increased from 11.6% in 2007 to 60.6% in 2015 (P< 0.0001). Older patients, females, and Hispanics were more likely to undergo thoracoscopic lobectomy, whereas morbidly obese patients, patients with higher American Society of Anesthesiology class, and patients with 4-6 frailty conditions had a lower likelihood of receiving thoracoscopic lobectomy or segmentectomy. Thoracic surgeons had 57% (odds ratio 1.57, 95% confidence interval 1.36-1.81) higher odds of performing thoracoscopic surgery than other surgeons. Thoracoscopic lobectomy or segmentectomy reduced risk of 30-day mortality (1.0% vs 1.9%; odds ratio 0.51, 95% confidence interval 0.37-0.70) and resulted in shorter length of stay (4 days vs 6 days; Beta coefficient = -0.37, P < 0.0001), and fewer complications. The frequency of thoracoscopic lobectomy or segmentectomy has increased substantially over the last 10 years and now accounts for over half of lobectomies. Video-assisted thoracoscopic surgery showed better outcomes than open lobectomy or segmentectomy.
