目的：建立一种能够评估缝合性能和质量的web应用程序。材料和方法：我们使用一些云计算系统、服务器、数据库和计算语言来开发web应用程序。我们用20个吻合的移植标本来优化应用。对吻合的移植物进行二维图像采集。5位血管外科医生利用该应用程序计算客观评分，并对吻合口评分进行主观排序。结果：使用该应用程序的步骤包括上传缝合的二维图像，手动跟踪缝线，按下按钮显示分数。在使用该系统超过1000次，没有出现服务器问题或故障后，我们证实了它的稳定性和易用性。系统在几秒钟内计算出分数。三个因素（咬合力、俯仰度和角度偏度）的得分范围为0.25 ~ 0.76。应用程序的误差范围是可以接受的。三个因素的类间相关系数（ICC(2,1)）为0.92。结论：应用程序的质量是可以接受的，考虑到操作者之间的分数变化范围小。
Objective: To create a web application that can evaluate suture performance and assess its quality.Material and Methods: We developed the web application using a few cloud computing systems, servers, database, and computing languages. We used 20 anastomosed graft samples for optimizing the application. The images of the anastomosed grafts were captured two-dimensionally. Five vascular surgeons utilized the application to compute the objective score and rank the score of the anastomoses subjectively.Results: Steps for using the application include uploading a two-dimensional image of sutures, tracing the stitch line manually, and pushing the button to have the score displayed. After using this system for more than 1,000 times without server issues or failures, we confirmed its stability and easy accessibility. The system calculated the score within several seconds. The score of the three factors (bite, pitch, and skewness of angle) ranged from 0.25 to 0.76. The error range of the application was acceptable. The interclass correlation coefficient (ICC (2,1)) of the three factors was 0.92.Conclusion: The quality of the application was acceptable considering the low range of interoperator variations in the scores.
