The impact of video endoscopy on surgical resident training was assessed by an analysis of 1531 endoscopic procedures (1057 video endoscopy and 474 fiberoptic endoscopy) and a standardized questionnaire response of surgical staff and residents. Video endoscopy provided advantages in the following areas: 1) Technical. Superior quality of image with a significantly greater resolution. 2) Procedural. Multiple simultaneous viewers for teaching and increased coordination for therapeutic maneuvers. 3) Educational. "Freeze frame" capability for real time teaching; video taping for subsequent consultation, review, or teaching conference, video tape evaluation at preoperative conferences, and archive of video tape for teaching file. 4) Documentation. For use review and quality assurance or for patient education. 5) Research. Investigation of video image enhancement techniques. 6) Physical comfort. Relief of many causes of strain and fatigue and elimination of potential danger to the endoscopist in certain therapeutic maneuvers. Residents learned video and fiberoptic endoscopy equally well, requiring only 3 to 5 procedures to learn each type of system. Experience in this teaching program indicates a decided advantage to incorporating video endoscopy into surgical residency training. After more than 1000 video endoscopy procedures, the novelty has worn off but enthusiasm persists; the video system is now a workhorse that provides greater technical capabilities and broader educational horizons while returning endoscopy to the realm of surgical education.
通过对1531例内镜手术（1057例视频内镜手术和474例纤维内镜手术）进行分析，并对手术人员和住院医师进行标准化问卷调查，评估了视频内镜对外科住院医师培训的影响。视频内镜在以下方面具有优势：1）技术方面。图像质量 superior，分辨率显著更高。2）操作方面。多个同步观看者用于教学，治疗操作的协调性增强。3）教育方面。具有“定格”功能用于实时教学；录像用于后续会诊、复习或教学会议，术前会议进行录像评估，并将录像存档用于教学档案。4）记录方面。用于回顾和质量保证或患者教育。5）研究方面。视频图像增强技术的研究。6）身体舒适度方面。缓解多种造成劳损和疲劳的因素，并消除某些治疗操作中对内镜医师的潜在危险。住院医师学习视频内镜和纤维内镜的效果相同，每种系统仅需3至5例手术即可学会。该教学项目的经验表明，将视频内镜纳入外科住院医师培训具有明显优势。在进行了1000多例视频内镜手术后，新鲜感已过，但热情依然存在；视频系统现在已成为主力工具，提供了更强的技术能力和更广阔的教育视野，同时将内镜检查回归到外科教育领域。
