Computer-based endoscopic simulators have been developed in recent years, and their usefulness has been reported. However, there is no blinded prospective randomized controlled study on esophagogastroduodenoscopy (EGD) training using virtual reality simulators. The present study aimed to assess the effectiveness of a computer-based simulator for basic training in EGD.
The GI-Mentor II simulator was used. The subjects were 20 hospital medical residents. After receiving an explanation regarding the fundamentals of endoscopy, 10 trainees were each randomized into a simulator group and a non-simulator group. The simulator group received 5 h of training with the GI-Mentor II plus bedside training, while the non-simulator group received bedside training. Subsequently, each subject performed endoscopy twice for assessment. Performance was evaluated according to a five-grade scale for a total of 11 items.
The score was significantly higher in the skills required for insertion into the esophagus, passing from the esophagogastric junction (EGJ) to the antrum, passing through the pylorus, and examination of the duodenal bulb and the fornix.
The performance of endoscopy was improved by 5 h of simulator training. The simulator was more effective with regard to the items related to manipulation skills. Computer-based simulator training in EGD is useful for beginners.
近年来已开发出基于计算机的内镜模拟器，且其效用已有报道。然而，尚无关于使用虚拟现实模拟器进行食管胃十二指肠镜检查（EGD）培训的盲法前瞻性随机对照研究。本研究旨在评估基于计算机的模拟器在EGD基础培训中的有效性。
使用GI-Mentor II模拟器。受试者为20名医院住院医师。在接受关于内镜检查基本原理的讲解后，10名受训者被随机分为模拟器组和非模拟器组。模拟器组接受5小时的GI-Mentor II培训加床边培训，而非模拟器组仅接受床边培训。随后，每位受试者进行两次内镜检查以进行评估。根据五级评分量表对总共11项内容的操作表现进行评估。
在食管插入、从食管胃交界处（EGJ）进入胃窦、通过幽门以及十二指肠球部和穹窿检查所需技能方面，得分显著更高。
5小时的模拟器培训可提高内镜检查操作表现。模拟器在与操作技能相关的项目上更有效。基于计算机的EGD模拟器培训对初学者有用。
