2D Versus 3D Laparoscopic Training on a Virtual Reality Simulator

Laparoscopy training programs with virtual reality simulators are widely used before new surgeons are allowed to operate on patients. Laparoscopic surgery results in shorter time to recover, less surgical trauma and thereby a shorter stay at the hospital compared with open surgery. However, it is more difficult to learn laparoscopic surgery, than open surgery, in part because surgeons have to work in a 3-dimensional space, through a 2-dimensional interface on a screen. This results in loss of depth perception and therefore a higher visual and cognitive load. This trial examines if using 3D vision instead of 2D vision on the laparoscopic virtual reality simulator reduces the time to reach proficiency, by decreasing the cognitive and visual load during practice on a Virtual Reality Simulator.

Laparoscopic simulator training to proficiency under 2D conditions

Primary outcomes

  1. Time (minutes) to reach the predefined proficiency level for the basic skills and the salpingectomy procedure

    Time frame: 1 year

Secondary outcomes

  1. Time (minutes) to reach the predefined proficiency level for the basic skills and salpingectomy procedure under 2D conditions after 3-6 weeks without laparoscopic training during the follow-up period

    Time frame: 1 year

Other outcomes

  1. Workload: NASA TLX questionnaire after the first and fifth attempt on procedural module,

  2. Visual and physical discomfort questionnaire after each training session (adverse effect: eye strain, headache, dizziness, nausea, tired and sore neck/back),

    Time frame: 1 year
