	abstract = {Background: This study evaluates the number of video-assisted thoracic surgery-lobectomies (VATS-lobectomies) required for an experienced consultant thoracic surgeon to obtain competence and to perform standard quality surgery. 
Methods: We have analysed the initial VATS-experience (January 2012 to September 2014) of a confirmed senior consultant who has performed 145 consecutive anatomic resections by thoracoscopy. After excluding bilobectomies, segmentectomies, and lobectomies for infectious disease, we have focused into 119 consecutive lobectomies, classified into 4 chronologic groups of 30 each. We have considered: demographics; pathology; postoperative outcomes; conversion rate; morbidity. We compared the 4 groups in a Bayesian inference model (very strong probability of a difference if Pr>95% or Pr>80% or 5%4=0.94, Pr3>4=0.937), as well as shorter hospital stay (Pr2>4=0.94, Pr3>4=0.937).
Conclusions: The learning curve was bimodal. After the initial 30 lobectomies, oncologic quality of the procedure improved and stabilized. The surgeon became less selective and accepted to proceed with more complex cases (incomplete fissures, pleural adhesions). Efficiency was obtained after 90 lobectomies (shorter operative time and lower conversion rate).},
