Thou shalt not trust online videos for inguinal hernia repair techniques.

Background: Videos are used by surgeons when learning new techniques; however, online videos are often not vetted. Our aim is to review online videos of laparoscopic inguinal hernia repairs based on a benchmark for critical view of the myopectineal orifice (MPO) and safe inguinal hernia repair as defined by Daes and Felix and commonly referred to as "the 9 Commandments."

Methods And Materials: YouTube was queried for "laparoscopic inguinal hernia repair." The top 50 videos were ranked based on number of views. Those endorsed and/or vetted by surgical societies were excluded (n = 4). Three expert hernia surgeons scored the videos based on adherence to the 9 Commandments.

Results: The 50 videos originated from 11 countries. They had 72,825 mean views and a mean runtime of 14 min. Videos obeyed a median of 77.8% of commandments shown. Eight videos (16%) obeyed all 9 (100%) commandments. Three videos (6%) failed to obey any commandments. Operations employed TEP (18, 36%), TAPP (28, 56%), and rTAPP (4, 8%) approach. Stratification by approach showed significant variance in commandments obeyed (Kurskal-Wallis, p = 0.016) with significant difference between TEP and rTAPP scores (p = 0.008) and no significant difference between TEP and TAPP or rTAPP and TAPP scores. Twenty-three videos (46%) displayed unsafe techniques including: threatened critical structures (16, 32%), rough tissue handling (15, 30%), and dangerous placement of fixation (9, 18%).

Conclusion: Online surgical videos on YouTube are not reliable in demonstrating best practices for minimally invasive inguinal hernia repairs. In our study, only 16% of the most viewed videos followed all 9 Commandments for critical view of the MPO. Many showed suboptimal repairs with significant safety concerns. While a significant number of online videos are a free and readily available resource for surgeons around the world, we recommend caution in relying on non-vetted videos as a form of surgical education.
