  Background: When starting with new surgical procedures, a gradual improvement in skills and results is expected. Pulmonary resection for early-stage non-small cell lung cancer (NSCLC) has advanced with technology, making robot-assisted thoracic surgery (RATS) an increasingly preferred method. At Akershus University Hospital (Ahus), exploring the learning curve associated with RATS offered valuable insights for optimizing surgical efficiency and improving patient outcomes. This study analyzes key operational variables and outcomes to highlight the skill acquisition process at a leading Norwegian healthcare center, aiming to describe the learning curve involved in transitioning from video-assisted thoracic surgery (VATS) to RATS for lung cancer lobectomies. Methods: This study was a retrospective analysis of the first 200 consecutive pulmonary lobectomies and bi-lobectomies with RATS in Norwegian University Hospital. We used cumulative sum (CUSUM) and risk-adjusted CUSUM (RA-CUSUM) analyses to evaluate operative times and perioperative complications. Results: The 200 patients had a median age of 70 (25th-75th percentile, 62-75) years; 109 (55%) were female, 159 (80%) had preoperative stage 0-IB, and 34 (17%) stage IIA-IIB. Of the procedures, 196 were lobectomies and 4 bi-lobectomies. Median operating time was 160 (25th-75th percentile, 120-195) minutes. Complications (Clavien-Dindo grade ≥2) were observed in 25.5% of cases. The conversion rate to thoracotomy was 1.5% and re-operation rate 3.0%. CUSUM analysis indicated a bi-phasic learning curve for operative times, with ongoing improvements observed after the 117th procedure. The RA-CUSUM analysis showed a steady decline in perioperative complications after the 94th procedure. Conclusions: The findings suggest that the transition from VATS to RATS as a standard surgical approach for pulmonary lobectomies was associated with an acceptable development of proficiency, procedure duration, and complication rates over time. Hence, implementation of the new RATS program was feasible and effective.
