Laparoscopy is difficult to master, in part because surgeons operate in a three-dimensional (3D) space guided by two-dimensional (2D) images. This trial explores the effect of 3D vision during a laparoscopic training program, and examine whether it is possible to transfer skills acquired with 3D conditions to 2D conditions.
We designed a randomized controlled trial where residents (n = 34) were randomized to proficiency-based laparoscopic simulator training under either 3D or 2D conditions. Subsequently, participants completed a retention test under 2D conditions.
Mean training time were reduced in the intervention group; 231 min versus 323 min; P = 0.012. There was no significant difference in the mean times to completion of the retention test; 92 min versus 95 min; P = 0.85.
3D vision reduced time to proficiency on a virtual-reality laparoscopy simulator. Furthermore, skills learned with 3D vision can be transferred to 2D vision conditions. Clinicaltrials.gov (NCT02361463).
腹腔镜检查术难以掌握，部分原因是外科医生在二维（2D）图像引导下于三维（3D）空间中进行操作。本试验探讨三维视觉在腹腔镜培训项目中的作用，并检验在三维条件下获得的技能是否有可能转移到二维条件下。
我们设计了一项随机对照试验，将住院医师（n = 34）随机分为两组，分别在三维或二维条件下接受基于熟练度的腹腔镜模拟器培训。随后，参与者在二维条件下完成一项留存测试。
干预组的平均培训时间减少；分别为231分钟和323分钟；P = 0.012。完成留存测试的平均时间无显著差异；分别为92分钟和95分钟；P = 0.85。
三维视觉缩短了虚拟现实腹腔镜模拟器上达到熟练程度所需的时间。此外，通过三维视觉学到的技能可以转移到二维视觉条件下。Clinicaltrials.gov（NCT02361463）。
