Abstract

Background: YouTube® has provided a forum to share surgical videos in the public domain which may be used for education. The quality of surgery and accompanying educational material is unknown. YouTube® videos of gastrectomy with D2 lymphadenectomy (D2-LND) for gastric cancer were evaluated for quality and completeness. Methods: YouTube® was searched using the terms “D2 lymphadenectomy” and “Gastric Cancer” for open and laparoscopic videos. The Korean Laparoscopic Gastrointestinal Surgical Society (KLASS) outlined 22 steps that define quality and completeness of D2-LND. These guidelines were used to score D2-LND for each video. Four physician reviewers independently scored each surgical video. Scores were compared using Student's t-test. Results: Ten laparoscopic and 10 open surgery videos were assessed. Each video was scored for quality and completeness and assigned a score out of 22. Mean score for open D2-LND was 15 (95% CI: 12.54-17.46). Mean score for laparoscopic D2-LND was 15.4 (95% CI: 14.34-16.46; P=0.77). The most consistently performed steps were the dissection of lymph node stations 1, 3, 4 and 5. The most commonly omitted steps were the dissection of lymph node station 6: exposure and identification of the lowest anterior superior pancreaticoduodenal vein; removal of the prepancreatic soft tissues above the lowest anterior superior pancreaticoduodenal vein; removal of the prepancreatic soft tissues above the level of the bifurcation of the anterior superior pancreaticoduodenal vein and right gastroepiploic vein. Conclusions: There is a wide range of quality and completeness of D2-LND videos. On average, D2-LND videos are only two-thirds complete.
