Abstract OBJECTIVES Subxiphoid uniportal video-assisted thoracoscopic segmentectomy (SU-VATs) has been widely adopted because it is associated with better postoperative pain scores. Nevertheless, it also has had some limitations that have gradually been decreasing. Therefore, our goal was to evaluate the change in perioperative results with SU-VATs as the learning curve developed to outline the current status and the points that should be of future concern. METHODS Three hundred patients who underwent SU-VATs from September 2014 to May 2018 were divided chronologically into 2 groups; group 1 comprised the first 150 cases and group 2 comprised the last 150 cases. Different perioperative variables were analysed and compared between the 2 groups. In addition, the cumulative sum analysis and multivariable logistic regression were conducted to identify the cut-off point and predictors of significant improvement in operative time. RESULTS The cumulative sum analysis showed significant improvement in the operative time after the 148th case. Group 2 showed a statistically significant decrease in operative time (104.3 ± 36.7 vs 132 ± 43.1 min; P < 0.001), amount of operative blood loss [50 (80 ml) vs 100 (50 ml); P < 0.001], chest drain duration (2.6 ± 1.6 vs 3.2 ± 1.4 days; P = 0.004) and hospital stay (3.7 ± 1.7 vs 4.2 ± 1.7 days; P = 0.008). The number of dissected lymph nodes was significantly higher in the second group [11 (4) vs 9 (4); P < 0.001]. CONCLUSIONS Limitations of SU-VATs are being overcome by the improvement in the learning curve and in the expertise of the surgeons. Our future concerns should focus on examining the long-term survival rate, the oncological efficacy and the effect on quality of life.
