Viabilidad, fiabilidad y validez del entrenamiento en simuladores y el desarrollo de habilidades en cirugía laparoscópica de un solo puerto

Background: Because the simulator training requires both investments in equipment and in training time, it is necessary that they prove useful in the development of skills. Hence, currently based training simulators for laparoscopic surgery is focused on building feasibility, reliability and validity to transfer the skills to clinical practice. Methods: Experimental, longitudinal, prospective and comparative study. We identifi ed four key skills in single port laparoscopic surgery and developed four exercises in simulators. Evaluations were made for 15 training sessions, clocking the time to perform properly each exercise and penalized for every error made. Results: 15 surgeons were evaluated. We observed a meaningful reduction in the score through the practice sessions and with highly signifi cant differences and a p-value < 0.0001. It can be seen that the dispersion of scores decreases with the decreasing execution time of each exercise. Conclusion: This technology appears to be appropriate to ensure skills development in single port laparoscopic surgery through a low cost device that allows the use of multiple instruments through a single incision.
