Abstract
Background: Video-based learning is used in surgical education due to its flexibility and cost-effectiveness. Endoscopic submucosal dissection (ESD) is a technically challenging procedure, and YouTube is an important source of educational videos on this topic. The laparoscopic video educational guide and scoring (LAP-VEGaS) system can objectively evaluate the educational quality of these videos.
Aim: To evaluate the educational quality of the most-viewed ESD videos on YouTube using the LAP-VEGaS score and to examine the relationship between quality and participation metrics.
Methods: On August 01, 2024, the 20 most popular videos were selected based on view count by searching for "endoscopic submucosal dissection" on YouTube. Two independent evaluators scored the videos using LAP-VEGaS (0-18). Videos scoring 9 or higher were classified as high quality (HQ; n = 12), while those scoring below 9 were classified as low quality (LQ; n = 8).
Results: The average number of views for the videos was 20,567 ± 38,269, the time elapsed since upload was 2751 ± 1264 days, the duration was 537 ± 301 s, and the average LAP-VEGaS score was 9.1 ± 5.2. HQ videos were longer (579 ± 295 s vs. 434 ± 190 s; P ≈ 0.08) and had a higher like rate (0.984 ± 0.02 vs. 0.94 ± 0.07; P < 0.05). Strong positive correlations were observed between likes and view rate (r = 0.979; P < 0.001) and video power index (r = 0.984; P < 0.001). Moderate correlations were found between the LAP-VEGaS score and duration (r = 0.515; P = 0.021) and similarity ratio (r = 0.492; P = 0.035).
Conclusion: The educational quality of popular ESD videos is heterogeneous, and unlike the number of views, interaction metrics, such as the like/view ratio and video duration, more reliably reflect educational value. Therefore, objective evaluation tools such as LAP-VEGaS are recommended to facilitate the selection of HQ content by educators and learners.
背景：基于视频的学习因其灵活性和成本效益而被用于外科教育。内镜下粘膜剥离（ESD）是一项技术上具有挑战性的手术，YouTube是该主题教育视频的重要来源。腹腔镜视频教学指导评分系统（LAP-VEGaS）可以客观地评价这些视频的教学质量。目的：利用LAP-VEGaS评分评估YouTube上观看次数最多的ESD视频的教育质量，并研究质量与参与指标之间的关系。方法：于2024年8月1日，在YouTube上搜索“内镜下粘膜夹层”，根据浏览量筛选出最受欢迎的20个视频。两名独立评估员使用LAP-VEGaS（0-18）对视频进行评分。9分及以上为高质量视频（HQ, n = 12）， 9分以下为低质量视频（LQ, n = 8）。结果：视频平均浏览量为20,567±38,269次，上传时间为2751±1264天，时长为537±301秒，平均LAP-VEGaS评分为9.1±5.2分。HQ视频较长（579±295 s vs. 434±190 s, P≈0.08），相似率较高（0.984±0.02 vs. 0.94±0.07,P < 0.05）。点赞与观看率（r = 0.979, P < 0.001）、视频功率指数（r = 0.984, P < 0.001）呈显著正相关。LAP-VEGaS评分与持续时间（r = 0.515; P = 0.021）和相似比（r = 0.492; P = 0.035）存在中度相关。结论：流行ESD视频的教育质量具有异质性，与观看次数不同，点赞/观看比、视频时长等交互指标更能可靠地反映教育价值。因此，建议使用客观的评估工具，如LAP-VEGaS，以方便教育者和学习者对HQ内容的选择。
