Toward technology-supported surgical training: the potential of virtual simulators in laparoscopic surgery.
OBJECTIVE
The mastery of manual skills that are indispensable for the performance of surgical tasks is a competence specific to surgery. One way of facilitating this acquisition is to move the training out of the operating room and all of its restrictions. Surgical training out of the operating room, also called simulation, has spread widely in the past decade, especially in laparoscopic and endoscopic surgery.


METHODS
This review assesses the role of virtual reality (VR) simulators in laparoscopic surgery and their actual impact on technical skills.


CONCLUSIONS
There is a wealth of simulators, ranging from low- to high-fidelity simulators incorporating haptic feedback. They comprise basic tasks, procedural modules, and full procedures. Virtual reality simulators have shown acceptable fidelity and validity evidence. Moreover, training out of the operating room on virtual reality simulators has demonstrated its positive impact on basic skills during real laparoscopic procedures in patients. The benefit of virtual reality over simple video trainers remains unclear for teaching basic skills. However, virtual reality simulators provide automatic feedback that permitted to design structured competency-based curricula and allow deliberate practice. Finally, advanced procedures and patient-specific models have been designed on virtual reality simulators, and further investigations are still awaited to appraise their educational value.
