Background
In the current era, trainees frequently use unvetted online resources for their own education, including viewing surgical videos on YouTube. While operative videos are an important resource in surgical education, YouTube content is not selected or organized by quality but instead is ranked by popularity and other factors. This creates a potential for videos that feature poor technique or critical safety violations to become the most viewed for a given procedure.
Methods
A YouTube search for “Laparoscopic cholecystectomy” was performed. Search results were screened to exclude animations and lectures; the top ten operative videos were evaluated. Three reviewers independently analyzed each of the 10 videos. Technical skill was rated using the GOALS score. Establishment of a critical view of safety (CVS) was scored according to CVS “doublet view” score, where a score of ≥5 points (out of 6) is considered satisfactory. Videos were also screened for safety concerns not listed by the previous tools.
Results
Median competence score was 8 (±1.76) and difficulty was 2 (±1.8). GOALS score median was 18 (±3.4). Only one video achieved adequate critical view of safety; median CVS score was 2 (range 0–6). Five videos were noted to have other potentially dangerous safety violations, including placing hot ultrasonic shears on the duodenum, non-clipping of the cystic artery, blind dissection in the hepatocystic triangle, and damage to the liver capsule.
Conclusions
Top ranked laparoscopic cholecystectomy videos on YouTube show suboptimal technique with half of videos demonstrating concerning maneuvers and only one in ten having an adequate critical view of safety. While observing operative videos can be an important learning tool, surgical educators should be aware of the low quality of popular videos on YouTube. Dissemination of high-quality content on video sharing platforms should be a priority for surgical societies.
