The role of virtual reality simulation training in laparoscopic skills training for young physicians
Objective To explore the significance of laparoscopic virtual reality simulation training by analyzing the learning curve of laparoscopic cholecystectomy among young general surgeons who had participated in laparoscopic skills training at our hospital.Methods Fifty young surgeons were divided into two groups,with the intervention group participating in virtual reality simulation training and the control group participating in traditional laparoscopic clinical training.After completion of the training,30 laparoscopic cholecystectomies were performed under the supervision of highly qualified surgeons with extensive laparoscopic experience.CUSUM analysis was applied to plot the trainees'surgical learning curve based on the completion rate,surgical score and operative time."x"is the number of surgical cases and"k"is the slope.The value of x when k=0 was calculated and the surgical learning curves and intraoperative scores of the 2 groups of trainees were compared.SPSS 23.00 was performed for t-test and Chi-square test.Results The intervention and control groups crossed the surgical learning curve at x=19.24±0.39 and x=21.72±0.73 respectively,with significant differences(P<0.01);the intervention and control groups scored(10.82±2.73)and(9.71±2.69)for gallbladder exposure(t=4.61,P<0.01),(12.59±3.12)and(8.87±2.99)for gallbladder dissection triangle(t=6.21,P<0.01),and(10.69±3.38)and(8.80±3.55)for gallbladder dissection(t=3.10,P<0.01).Conclusions Virtual reality simulation training can facilitate the translation of basic laparoscopic training skills into clinical skills and can promote the growth of young general surgeons.
