Comparative effectiveness and cost-efficiency of surgical approaches for thymectomy.

Abstract Background We compared the clinical outcomes and cost-efficiency of surgical approaches (sternotomy-open, video assisted thoracoscopic surgery, and robotic assisted thoracic surgery) for thymectomy. Methods This is a retrospective review of 220 consecutive patients who underwent thymectomy between January 1, 2007, and January 31, 2017. Surgical approach was determined by the surgeon, but we only included cases that could be resected using any of the 3 approaches. Results Open approach was used in 69 patients, whereas minimally invasive technique was used in 151 (97, video assisted thoracoscopic surgery; 54, robotic assisted thoracic surgery). Open surgery was associated with greater total hospital cost ($22,847 ± $20,061 vs $14,504 ± $10,845, P Conclusion Minimally invasive techniques were equally efficacious compared with the open approach in the resection of the thymus. Additionally, their use was associated with decreased hospital duration of stay and reduced cost. Hence the use of minimally invasive approaches should be encouraged in the resection of thymus.
