ABSTRACTObjective: To compare the ability to develop surgical endoscopic skills between videogame players, musical instrument players and a control group. Setting: Medicine school, Benemérita Universidad Autónoma de Puebla. Design: Comparative, experimental, longitudinal, homodemic and prospective study. Statistical analysis: ANOVA. Material and methods: 45 high school students were included. Fifty expert video game players (group A), 15 played some musical instrument (group B), and a control group (group C). Each worked 4 exercises: object transfer, fine movements, spatial navigation and intracorporeal knot. They repeated each 15 times and they were evaluated using a score constructed with time plus mistakes made. Results: Demographics were similar. One way ANOVA was calculated in repetitions 1, 5, 10 and 15. All had better scores as they went through. Group B scored better than group C and group A better than group B (p ‹ 0.05). All groups reached a plateau and at the end of the repetitions. Conclusions: Previous experience with video games or musical instruments shortens the learning curve of basic skills in ES with a physical simulator, and this could be a factor in surgical education. However, at the end of the practicing period, the performance was comparable among groups, suggest ing that the most important factor to develop skills is the feasibility to practice.
