Learning curve of uniportal video-Assisted thoracoscopic lobectomy: An analysis of the proficiency of 538 cases from a single centre true true /api/journal/10028634 REVIEWED INTERACTIVE CARDIOVASCULAR AND THORACIC SURGERY 1569-9293 1569-9285 true false 10028634 false 10028634 true 1569-9293 1569-9285 Journal FOREIGN 34 5 799 807 799 9 2022 OBJECTIVES: Uniportal video-Assisted thoracoscopic surgery (UniVATS) is widely used as a minimally invasive thoracic operation. The goal of our study was to analyse the effect of long-Term experience with the UniVATS lobectomy on the learning curve. METHODS: The learning curves were quantitatively evaluated by the unadjusted cumulative sum, and they were segmented using joinpoint linear regression analysis. The variables were compared between subgroups using trend analysis, and linear regression analysis was applied to correlate clinical characteristics at different stages of the learning curve with the duration of the operation. RESULTS: The learning curve for the UniVATS lobectomy can be divided into 3 phases of proficiency at ?200-300 procedures, with a fourth phase as the number of procedures increases. The 1st-52nd, 52nd-156th, 156th-244th and 244th-538th procedures comprised the preliminary learning stage, preliminary proficiency stage, proficiency stage and advanced proficiency stage, respectively. Surgical outcomes and their variability between stages improved with increasing case numbers, with the most significant addition of an auxiliary operating port and conversions. In multivariable analysis, as stages progressed, influences other than surgical experience increased the operative time, with male and extensive pleural adhesions in the preliminary proficiency stage; male and incomplete pulmonary fissures in the proficiency stage; and male, extensive pleural adhesions and incomplete pulmonary fissures in the advanced proficiency stage. CONCLUSIONS: As the number of procedures increases, there may be 4 different proficiency stages in the UniVATS lobectomy learning curve. The surgeon enters the fourth stage at approximately the 244th procedure. Moreover, at stage 4, the perioperative indicators tend to stabilize, and influences other than surgical experience become more significant. © 2022 The Author(s) 2022.
