Backgrounds: The aim of our study is to describe the learning curve for uniportal video-assisted thoracoscopic surgery (VATS) lobectomy from our single center's experience for adopting it because uniportal VATS is generally considered a technically difficult procedure. Methods: A retrospective review of all 164 consecutive patients who underwent uniportal VATS lobectomy between June 2015 and February 2020 was done. A cumulative summation (CUSUM) method was applied to evaluate the learning curves of the operation time. Results: Among the 164 patients, the CUSUM value inflected at the 31st case. Ninety-five consecutive patients underwent uniportal VATS upper lobectomy. The other 69 consecutive patients underwent uniportal VATS lower lobectomy. The operation time CUSUM learning curve analysis revealed that the curves descended from the 21st case in upper lobectomy group and the 12th case in lower lobectomy group. Conclusion: Operators are required to experience at least 21 cases for upper lobectomy and 12 cases for lower lobectomy until the operation time is stabilized.
