Background Procedural simulation enhances early endoscopy training. Multiple commercial simulators are available; however, their application is limited by cost and poor user compliance. First-person "shooter" (FPS) video games are popular. In this study, we aimed to show that a novel in-house designed colonoscope controller used to play an FPS video game shares similar constructs with real-life endoscopy. Methodology Participants completed the first three levels on an FPS video game, Portal (Valve Corporation, Bellevue, WA), first using a conventional controller and then the modified endoscope controller. A total of 12 expert endoscopists and 12 surgical residents with minimal endoscopy experience were evaluated based on completion time, button presses, and hand motion analyses. Results Experts outperformed novices for completion time (expert: 944 seconds; novice: 1,515 seconds; p = 0.006) and hand movements (expert: 1,263.1; novice: 2,052.6; p = 0.004) in using the novel colonoscope controller. There was no difference in button presses or total path length traveled. Furthermore, performance did not differ using conventional game controls. Conclusions Experts outperformed novices using the endoscope but not the conventional controller with respect to the economy of movement and completion time. This result confirms that our endoscope-controlled video game shares similar paradigms with real-life endoscopy and serves as a first step toward creating a more enjoyable and cheaper alternative to commercially available endoscopy simulators.
背景 程序模拟可增强早期内镜培训。市面上有多种商业模拟器；然而，其应用受到成本和用户依从性差的限制。第一人称“射击”（FPS）视频游戏很受欢迎。在本研究中，我们旨在表明，一种用于玩FPS视频游戏的新型内部设计的结肠镜控制器与现实生活中的内镜检查具有相似的结构。方法 参与者先使用传统控制器，然后使用改良后的内镜控制器，完成一款FPS视频游戏《传送门》（Valve公司，华盛顿州贝尔维尤）的前三关。基于完成时间、按键次数和手部动作分析，对12名内镜专家和12名内镜经验极少的外科住院医师进行了评估。结果 在使用新型结肠镜控制器时，专家在完成时间（专家：944秒；新手：1515秒；p = 0.006）和手部动作（专家：1263.1；新手：2052.6；p = 0.004）方面优于新手。按键次数或总行进路径长度没有差异。此外，使用传统游戏控制器时表现也没有差异。结论 在动作经济性和完成时间方面，专家使用内镜控制器的表现优于新手，但使用传统控制器时并非如此。这一结果证实，我们的内镜控制视频游戏与现实生活中的内镜检查具有相似的模式，是朝着创建一种比市售内镜模拟器更有趣、更便宜的替代品迈出的第一步。
