Virtual reality (VR) simulators may hold a role in the assessment of trainee abilities independent of their role as instructional instruments. Thus, we piloted a course in flexible endoscopy to surgical trainees who had met Accreditation Council for Graduate Medical Education endoscopy requirements to establish the relationship between metrics produced by a VR endoscopic simulator and trainee ability. After a didactic session, we provided faculty instruction to senior residents for Case 1 upper endoscopy and colonoscopy modules on the CAE EndoscopyVR. Course conclusion was defined as a trainee meeting all proficiency standards in basic endoscopic procedures on the simulator. Simulator metrics and course evaluation comprised data. Eleven and eight residents participated in the colonoscopy and upper endoscopy courses, respectively. Average time to reach proficiency standards for esophagogastroduodenoscopy was 6 and 13 minutes for colonoscopy after a median of one (range, one to two) and one (range, one to four) task repetitions, respectively. Faculty instruction averaged 7.5 minutes of instruction per repetition. A subjective course evaluation demonstrated that the course improved learners' knowledge of the subject and comfort with endoscopic equipment. Within a VR-based curriculum, experienced residents rapidly achieved task proficiency. The resultant scores may be used as simulator guidelines for resident assessment and readiness to perform flexible endoscopy.
虚拟现实（VR）模拟器在评估实习生能力方面可能具有一定作用，这与其作为教学工具的作用无关。因此，我们为已满足研究生医学教育认证委员会内镜检查要求的外科实习生开设了一门灵活内镜检查课程，以确定VR内镜模拟器产生的指标与实习生能力之间的关系。在一次理论课程之后，我们为高年级住院医师提供了关于CAE EndoscopyVR上病例1上消化道内镜检查和结肠镜检查模块的教员指导。课程结束的定义为实习生在模拟器上的基本内镜操作中达到所有熟练标准。模拟器指标和课程评估构成了数据。分别有11名和8名住院医师参加了结肠镜检查和上消化道内镜检查课程。在分别经过中位数为1次（范围为1至2次）和1次（范围为1至4次）任务重复后，食管胃十二指肠镜检查达到熟练标准的平均时间分别为6分钟和13分钟用于结肠镜检查。教员指导平均每次重复7.5分钟。主观课程评估表明，该课程提高了学习者对该主题的知识以及对内镜设备的操作舒适度。在基于VR的课程中，经验丰富的住院医师能够迅速达到任务熟练程度。所得分数可用作住院医师评估和进行灵活内镜检查准备情况的模拟器指导标准。
