Relation between educational reliability and viewer interest in YouTube® videos depicting endometrioma cystectomy...

To assess the reliability of YouTube® endometrioma cystectomy videos based on technical video analysis and considering the surgical steps.

The present study yielded 756 videos after a search on YouTube® with the keywords "endometriosis cystectomy, endometrioma cystectomy, chocolate cyst cystectomy, and endometrioma surgery'' during the period from January 7, 2007 to January 7, 2019. The viewer interest parameters such as total number of subscribers, views, likes, dislikes, comments, source of the videos, and the date of upload were assessed. Besides, the surgical steps were also evaluated considering committee suggestions.

There were 140 (78.7 %) videos in Group 1 (not useful and slightly useful) and 38 (21.3 %) videos in Group 2 (useful and very useful). The mean numbers of subscribers, views, and likes were 5737.843 ± 15741.302, 10614.257 ± 32702.339, and 17.7 ± 43.57, respectively, in Group 1, and 851.052 ± 1613.599, 8192.55 ± 15989.955, and 11.92 ± 27.52, respectively, in Group 2. The type of surgery was significantly different between the study groups. The videos of cases with robotic surgeries presented more useful descriptive information (p =  0.003). There was a significant difference between the study groups regarding the type of hemostasis. The presence of didactic steps was higher in Group 2 (47.4 %) compared to Group 1 (28.6 %) (p =  0.02) CONCLUSIONS: Overall, only around 21 % of YouTube videos presenting endometrioma surgery were defined as useful or very useful. The interest rates of the viewers may not compatible with the usefulness rate of the videos.
