Does playing video games improve surgical skill? The Top Gun Laparoscopic Skills and Suturing Program was developed to help surgeons develop the skill set necessary for laparoscopic surgery. Because of the similarity in many of the skills involved in video games and laparoscopic surgery, it was hypothesized that surgeons with greater prior video game experience might acquire the skills required in laparoscopic surgery more easily. Thirty-three surgeons participated in the study and were classified into three categories - never used, under three hours, and more than three hours - depending on the number of hours they played video games at the height of their video game use. They also performed Top Gun drills and received a score based on the time to complete the drill and the number of errors made, with lower scores indicating better performance.
