Learning Curve in Thoracoscopic Mediastinal Mass Excision: A Multicenter Retrospective Cohort Study Using Cumulative Sum and Multivariable Regression Analysis: doi: 10.7417/CT.2026.2165

Background

Video-assisted thoracoscopic surgery (VATS) mediastinal mass excision has become the standard approach for anterior mediastinal lesions. Understanding its learning curve is essential for surgical training and quality assurance. This study evaluated the learning curve of thoracoscopic mediastinal mass excision and estimated the number of cases required to achieve surgical proficiency.
