Objective: The aim of the cross-over study was to evaluate skill acquisition in lobectomy-naive surgical trainees completing a 4-week program to learn VATS lobectomy on a virtual reality surgical simulator (LapSim). Method(s): Lobectomynaive surgical trainees (year 1 and 2 postgraduation) were enrolled during the COVID pandemic from March to June 2021 for a 4-week course on basic VATS skills and right upper lobectomy. They were divided into 2 groups. Both groups completed an initial assessment, Group 1 completed the course first, then both groups completed a second assessment. Then Group 2 completed the course, and both groups completed a final assessment. Skill acquisition was assessed using instrument movement, procedure time, and blood loss for both the trained operation and an untrained operation (left lower lobectomy). Result(s): 16 trainees were enrolled, 10 completed the training program. There was no difference in baseline assessment. After Group 1 completed the training, they outperformed Group 2 in all metrics but this did not reach statistical significance. After training Group 2 at week 8, there was no longer difference in performance from Group 1. After completing the training program, the entire cohort showed a significant improvement in basic VATS tasks as well as lobectomies. There was statistically significant improvement in both right upper lobectomy instrument movement (P=0.002) and time (P=0.009) and left lower lobectomy time (P=0.047). Conclusion(s): This study showed that VATS simulation training on LapSim allowed junior trainees to learn advanced VATS resection during a pandemic and within 4 weeks. The acquired skills is transferrable to untrained operations. (Table Presented).
