Self-directed training with e-learning using the first-person perspective for laparoscopic suturing and knot tying: a randomised controlled trial : Learning from the surgeon's real perspective.

BACKGROUND: Laparoscopic suturing and knot tying is essential for advanced laparoscopic procedures and requires training outside of the operating room. However, personal instruction by experienced surgeons is limitedly available. To address this, the concept of combining e-learning with practical training has become of interest. This study aims to investigate the influence of the first-person perspective in instructional videos, as well as the feasibility of a completely self-directed training curriculum for laparoscopic suturing and knot tying.
MATERIALS AND METHODS: Ninety-one laparoscopically naïve medical students were randomised into two groups training with e-learning videos in either the first-person perspective (combining endoscopic view and view of hands/instruments/forearm motion) or the endoscopic view only. Both groups trained laparoscopic suturing and knot tying in teams of two until reaching predefined proficiency levels. Blinded, trained raters regularly assessed the participants' performance by using validated checklists. After training, participants filled out questionnaires regarding training experience and personal characteristics.
RESULTS: Average training time to reach proficiency did not differ between groups [first-person perspective (min): 112 ± 44; endoscopic view only (min): 109 ± 47; p = 0.746]. However, participants from both groups perceived the first-person perspective as useful for learning new laparoscopic skills. Both groups showed similar baseline performances and improved significantly after training [Objective Structured Assessment of Technical Skills (OSATS) (max. 37 points): first-person perspective: 30.3 ± 2.3; endoscopic view only: 30.8 ± 2.3]. All participants managed to reach proficiency, needing 8-43 attempts without differences between groups. Visuospatial abilities (mental rotation) seemed to enhance the learning curve.
CONCLUSION: Modifying instructional videos to the first-person perspective did not translate into a better performance in this setting but was welcomed by participants. Completely self-directed training with the use of e-learning can be a feasible training approach to achieve technical proficiency in laparoscopic suturing and knot tying in a training setting.
