Video playback as a teaching tool to improve residents’ laparoscopic performance: a randomized controlled trial

Goal of the study

In this single masked randomized controlled study, we are evaluating whether watching video recordings of oneself performing fundamental laparoscopic skills (FLS) exercises results in an improvement in 30-point assessment of the assessment Global Operative Laparoscopic Skills (GOALS) in Obstetricians and Gynecologists (Ob/Gyn).


Twenty-three obstetrics and gynecology residents in the 2020-2021 academic year completed FLS exercises while being timed, videotaped, and receiving real-time feedback from an obstetrics and gynecology faculty member. The basic BUTS evaluation was carried out by the participants and the teachers. After the intervention, all participants then repeated the FLS exercises while being timed and again scored using the GOALS assessment. Each participant completed the study in a single session. In addition, all participants completed a pre-test and post-test survey.

Twelve participants were randomized to the intervention and were allowed to watch their video recording in addition to receiving verbal feedback, while the remaining 11 received verbal feedback only.

Measures and main results

There were significant improvements in faculty scores (p


While all learners objectively benefit from watching recordings of themselves performing surgical tasks, advanced learners may benefit the most when video recordings are used as an educational tool.
