Abstract

Background: To determine prospectively if simulator-based laparoscopic training could improve laparoscopic skills of gynecology residents. Study Design: Twenty-six gynecology residents were enrolled in a laparoscopy training curriculum involving didactics, self-paced learning modules, and graded simulator-based laparoscopic training modules. Six simulator tasks were developed to introduce incremental levels of difficulty. Residents were tested on bead/peg manipulation, passing of a specially designed "key," cutting of lines and circles on a two-layer latex glove, and laparoscopic suturing followed by both intra- and extracorporeal knot tying. Times for each task and penalties for errors were assessed at baseline and after 3 months of training. Results: Twenty-six residents completed initial baseline and 3-month evaluations. Average summary time (including 30-seconds penalties for each error) at baseline was 64 minutes and 36 minutes at 3-month evaluation (p < 0.001). For PGY1 baseline summary times averaged 83 minutes compared with 50 minutes at 3 months (p = 0.006). For PGY4 baseline summary times averaged 49 minutes compared with 28 minutes at 3 months (p = 0.05). All individual tasks demonstrated substantial improvement (p < 0.001) from baseline to 3-month evaluation. Baseline summary scores demonstrated correlation between PGY training year and overall score (p < 0.001) consistent with earlier ability and training. Three-month scores demonstrated equalization of skill level across PGY2 through PGY4. Conclusions: A dedicated simulator-based laparoscopic training curriculum has the ability to improve basic laparoscopic skills in a gynecologic residency, as measured by timed and scored simulator tasks. Construct validity was demonstrated by measuring substantial improvement in performance with increasing residency training, and with practice.
