- W4283168263 abstract "TYPE: Late Breaking Abstract TOPIC: Cardiothoracic Surgery PURPOSE: The goal of the study was to analyze the effect of long-term experience with uniportal video-assisted thoracoscopic surgery(UniVATS) lobectomy on the learning curve. METHODS: The learning curves were quantitatively evaluated by the unadjusted cumulative sum, and they were segmented using Joint point linear regression analysis. The variables were compared between subgroups using trend analysis, and linear regression analysis was applied to correlate clinical characteristics with procedure time. The learning curve of UniVATS lobectomy can be divided into 3 phases of proficiency at approximately 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 number, 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 (EPA) in the preliminary proficiency stage; male and incomplete pulmonary fissures(IPF) in the proficiency stage; and male, EPA, and IPF 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. CLINICAL IMPLICATIONS: This study is a very important addition to the field of learning curve analysis for thoracoscopic surgery. DISCLOSURE: No significant relationships. KEYWORD: UniVATS" @default.
