Abstract
INTRODUCTION: The objective of this study was to determine if preoperative warming up by obstetrics and gynecology trainees, using a validated bench model for intracorporeal suturing, improves efficiency, precision, and quality of laparoscopic suturing. METHODS: A randomized crossover design was used. Fourteen obstetrics and gynecology residents were randomized [3 junior (year 2) and 11 senior (years 3-5) residents]. Participants were randomized to warm-up or no warm-up and then acted as their own controls at least 2 weeks later. Warm-up consisted of the use of a laparoscopic bench model to practice intracorporeal suturing for 15 minutes. All participants performed a prevalidated intracorporeal suturing task (after either warm-up or no warm-up), which was scored based on time, precision, and knot strength. Each participant also completed a questionnaire anonymously to determine if they believed that warming up improved their performance, regardless of the score they received. RESULTS:Thirteen participants completed the study. There was no difference in score when warm-up was compared with no warm-up for the group as a whole. When the junior residents were excluded from the analysis, however, analysis of variance showed a significant improvement in score only when a warm-up was completed in the second session (P = 0.022). The questionnaire revealed that 81.8% of participants felt that warming up subjectively improved their ability, independent of their actual score. CONCLUSIONS: This study demonstrates that a preoperative warm-up, combined with repetition, is beneficial in improving senior obstetrics and gynecology residents' laparoscopic suturing performance. This demonstrates a novel approach to resident education for teaching advanced laparoscopic skills.
