Objectives: To assess the effect of a surgical teaching video on resident knowledge and performance of a laparoscopic salpingo-oophorectomy (LSO). Methods: A randomized controlled trial was conducted with first and second year gynaecology residents at the University of Toronto. Participants were assigned to either the video group or to the traditional training group. Participants completed a demographic survey and knowledge questionnaire preceding their performance of an LSO in the operating room. Video recordings of surgical performance were analyzed by two blinded raters using the objective structured assessment of technical skills OSATS (20 points) and an LSO specific tool (30 points). Participants completed a self-assessment questionnaire following the procedure.Results: Twenty-four residents were recruited and equally distributed between groups. There were no significant differences between their demographic variables. For the primary outcome, there were no significant differences in mean OSATS scores (10.64, SD 2.05 vs 11.55, SD 1.85, p=0.3) or LSO specific tool scores (16.45, SD 2.68 vs 17.85, SD 2.63, p=0.24). However, there was a significant difference in mean knowledge scores between the video (8.42, SD 0.79) and the traditional training (7.11, SD 1.36, p=0.01) groups. In addition, residents in the video group had more confidence of their pelvic anatomy knowledge (3.83/5, SD 0.39 vs 3.00, SD 1.00, p=0.04). Conclusions: For junior learners, use of an LSO video improved knowledge and confidence in anatomy but did not translate to improved surgical performance in the operating room. Surgical videos are a useful adjunct and compliment hands-on technical teaching.
