Recent technical development has led to remarkable performances in video-guided surgical procedures. A video-endoscopic system (VES) is evaluated as an alternative magnifying solution for microsurgical procedures and compared to table-top microscopes in terms of technical and surgical aspects. Six surgical residents without microsurgical experience, alternating both systems, performed each 12 aortic end-to-end anastomoses on Sprague-Dawley rats using the triangulation technique. All anastomoses underwent quality review, total and single suture time, suture spacing, vessel bite, vessel overlapping and wall penetration were evaluated and graded. Overall anastomosis quality score was 52.28 (out of a maximum of 140) using the microscope and 42.7 using the VES. Despite significant differences in total anastomosis time, the learning curves are similar for the two systems and no major differences were noted in terms of overall anastomosis quality. Video-assisted microsurgery can become a useful instrument for microsurgery training.
近期的技术发展已在视频引导手术操作中取得了显著成效。一种视频内窥镜系统（VES）被评估为显微外科手术的替代放大解决方案，并在技术和手术方面与台式显微镜进行了比较。六名没有显微外科经验的外科住院医师交替使用这两种系统，采用三角测量技术在Sprague-Dawley大鼠身上各进行了12次主动脉端端吻合术。所有吻合口均接受质量评估，对总缝合时间和单次缝合时间、缝合间距、血管咬合力、血管重叠情况及管壁穿透情况进行了评估和分级。使用显微镜时，总体吻合质量评分为52.28（满分140分），使用VES时为42.7分。尽管总吻合时间存在显著差异，但两种系统的学习曲线相似，在总体吻合质量方面未发现重大差异。视频辅助显微外科手术可成为显微外科培训的有用工具。
