Educational quality of YouTube videos on robot-assisted thymectomy: a LAP-VEGaS-based evaluation.
Article in BMC medical education, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundVideo-based learning has become an integral component of surgical training, especially with the growing implementation of minimally invasive techniques such as robot-assisted thoracic surgery (RATS). However, the educational value of freely accessible online videos remains unclear. We aimed to assess the educational quality of the most-viewed YouTube videos on RATS thymectomy using a structured evaluation framework and to analyze the relationship between video-related parameters and educational performance.
methodsA structured search of YouTube was conducted on March 11, 2026, using the predefined search term "robotic thymectomy." The 100 most-viewed videos were screened, and 38 videos met the inclusion criteria. Videos were assessed by two experienced thoracic surgeons using the 9-item LAP-VEGaS (Laparoscopic Surgery Video Educational Guidelines) scoring system, which was applied as a structured framework for evaluating general surgical video educational quality. Video characteristics were recorded and analyzed in relation to educational quality.
resultsThe mean LAP-VEGaS score was 9.76 ± 3.42 (range: 4-16), and only 17 videos (44.7%) achieved a score ≥ 11, indicating acceptable educational quality. Most videos were uploaded by individual surgeons and were predominantly of 720p resolution. View count was positively correlated with likes and time since upload but showed no significant association with LAP-VEGaS score.
conclusionAmong highly viewed English-language YouTube videos on RATS thymectomy, a considerable proportion did not meet expected standards for structured surgical education. Common popularity metrics, particularly view count, are not reliable indicators of educational value. Structured and standardized approaches to video creation should be promoted to enhance the overall quality and trustworthiness of online surgical education materials.
