Abstract
Participants in a twoday multimodality training for laparoscopic surgery used box trainers live animal training and cadaveric training on the pulsating organ perfusion POP trainer in a structured and standardized training program The participants were divided into two groups The VR group n = 13 also practiced with VR training during the program whereas the control group n = 14 did not use VR training The training modalities were assessed using questionnaires with a fivepoint Likert scale after the program Concerning VR training members of the control group assessed their expectations whereas the VR group assessed the actual experience of using it Skills performance was evaluated with five standardized test tasks in a live porcine model before pretest and after posttest the training program Laparoscopic skills were measured by task completion time and a general performance score for each task Baseline tests were compared with laparoscopic experience of all participants for construct validity of the skills testThe expected benefit from VR training of the control group was higher than the experienced benefit of the VR group Box and POP training received better ratings from the VR group than from the control group for some purposes Both groups improved their skill parameters significantly from pretraining to posttraining tests score +17 P 001 time −29 P 001 No significant difference was found between the two groups for laparoscopic skills improvement except for the score in the instrument coordination task Construct validity of the skills test was significant for both time and score
