    Abstract:
    BACKGROUND: The learning curve in laparoscopic surgery may be associated with higher patient risk, which is unacceptable in the setting of kidney donation. Virtual reality simulators may increase the safety and efficiency of training in laparoscopic surgery. The aim of this study was to investigate if the results of a training session reflect the actual skill level of transplantation surgeons and whether the simulator could differentiate laparoscopic experienced transplantation surgeon from advanced trainees. SUBJECTS AND METHODS: 16 subjects were assigned to one of two groups: 5 experienced transplantation surgeon and 11 advanced residents, with only assistant role during transplantation. The level of performance was measured by a relative scoring system that combines single parameters assessed by the computer. RESULTS: The higher the level of transplantation experience of a participant, the higher the laparoscopic performance. Experienced transplantation surgeons showed statistically significant better scores than the advanced group for time and precision parameters. CONCLUSIONS: Our results show that performance of the various tasks on the simulator corresponds to the respective level of experience in transplantation surgery in our research groups. This study confirms construct validity for the LapSim. It thus measures relevant skills and can be integrated in an endoscopic training and assessment curriculum for transplantations surgeons.
