Pre-course instructional videos and home-based laparoscopic suturing simulation enhances the educational impact of a laparoscopic training course

Abstract

Introduction

We developed a home-based laparoscopic suturing simulation (HBLSS) technique, which is intended to improve the impact of a structured laparoscopic training course.

Method

A group of sixteen students were provided with the educational video, and after two weeks, all students were observed and timed performing a laparoscopic reef knot. The students were then randomized into two cohorts. The exclusive video group continued using the video for a further two weeks. The second group were shown the HBLSS technique and told to use this in conjunction with the video for a further two weeks.

Results

The entire cohort had an initial median time to form an intracorporeal reef knot of 190 s (range 459, IQR 128). After two additional weeks of using the educational video exclusively, the median time was reduced to 85 s (range 282, IQR 125), whereas the HBLSS and educational video group had a median post-training time of 28.5 s (range 36, IQR 18.5). There was a clear statistical difference between the exclusive video group and the HBLSS and video group (P = 0.008). There was also an improvement from the movement of both instruments to one instrument, reduced crossing of instruments and reduced transverse movement in the HBLSS and video group.

Conclusion

A combination of video-based teaching and HBLSS was associated with improved laparoscopic intra-corporeal knot-tying skills in comparison to the exclusive video-based teaching. This reflects the importance of imparting both cognitive and psychomotor skills to students practising laparoscopic surgery.
