This study examines prefrontal responses of surgeons of varying experience levels during a suturing drill to evaluate laparoscopic surgery skills.

Teaching and assessment of laparoscopic skills are currently essential components of surgical training. The Fundamentals of Laparoscopic Surgery (FLS) is a widely adopted training program based on expert-derived benchmarks; technical skills are assessed and completion is a mandatory criterion for general surgery board certification in the United States.1 However, is attainment of technical proficiency synonymous with being a safe surgeon? Intraoperative errors persist and are thought to be related to errors in cognition2 as opposed to technical failure per se. The prefrontal cortex (PFC) is a brain region associated with attention and executive function serving as a scaffold to support novel task demands during effortful unrefined performance.3 Studies examining cortical correlates of technical skills acquisition have observed predictable attenuation in PFC response alongside improvement in technical performance4,5; however, this has not been adequately tested for challenging laparoscopic skills.

A Participant’s Brain Activity Monitored During Performance of Laparoscopic Surgical Task

The image illustrates the experimental set-up of a participant performing laparoscopic suturing and knot tying. Prefrontal cortex activity was recorded by a 44-channel optical topographic system. Emitters (red) and detectors (blue) detect cortical activity when placed over a region of interest.
