Abstract：Objective:To compare the application effects of virtual-reality based laparoscopic training simula-tors versus traditional training strategy in pediatric minimally invasive surgery training program.Methods:We retro-spectively analyzed the training data of trainees who participated in the pediatric urology minimally invasive program in Ruijin Hospital Affiliated to Shanghai Jiaotong University School of Medicine(traditional group)and the Seventh Medical Center of PLA General Hospital(hybrid group)from September 2020 to September 2023.A total of 24 trainees were included in this study,including 10 in the traditional group and 14 in the hybrid group.None of the train-ees had experience in laparoscopy.The traditional group were trained with the traditional laparoscopic simulator while the hybrid group were trained with the traditional laparoscopic simulator combined with LapSim virtual-reality tech-nique.The trainees'baseline data,project completion assessment and perioperative data of the patients in the two groups were compared.The operation videos were scored by the same surgeon according to the global overall laparo-scopic skills scoring scale(GOALS).Results:There were no statistically significant differences between the two groups in terms of age,gender,education,and title(P=0.576,1.000,1.000,0.615,respectively).All trainees partic-ipated the 3 months training program(including 48 hours of laparoscopic training).The examination surgery was lapa-roscopic orchiopexy.The average time of intra-abdominal operation time and the results of ultrasound had no signifi-cant differences between the two groups(P=0.070,0.417,respectively).The average GOALS scores of the trainees in the traditional group was 16.4±1.26,and 16.4±1.26 in the hybrid group,with significant difference(t=3.312,P=0.003).There had no significant differences in the subgroups of GOALS score such as both hands coordi-nation,operation efficiency,tissue injury control,and independent performance between the two groups(P=0.636,0.862,0.089,0.278,respectively),but there was a significant difference in depth perception between traditional group(3.20±0.63)and hybrid group(3.79±0.70,t=2.103,P=0.047).Conclusion:Combined the traditional lapa-roscopic training simulator with virtual reality laparoscopic simulator can be more efficiency of minimally invasive sur-gical training in pediatric urology and holds significant clinical value for broader implementation.
