Purpose:
Pediatric surgeons require highly advanced skills when performing endoscopic surgery; however, their experience is often limited in comparison to general surgeons. The aim of this study was to evaluate the effectiveness of endoscopic surgery training for less-experienced pediatric surgeons and then compare their skills before and after training.
Methods:
Young pediatric surgeons (n = 7) who participated in this study underwent a 2-day endoscopic skill training program, consisting of lectures, box training and live tissue training. The trainees performed the Nissen construction tasks before and after training using our objective evaluation system. A statistical analysis was conducted using the two-tailed paired Student's t tests.
Results:
The time for task was 984 ± 220 s before training and 645 ± 92.8 s after training (p < 0.05). The total path length of both forceps was 37855 ± 10586 mm before training and 22582 ± 3045 mm after training (p < 0.05). The average velocity of both forceps was 26.1 ± 3.68 mm/s before training and 22.9 ± 2.47 mm/sec after training (p < 0.1). The right and left balance of suturing was improved after training (p < 0.05).
Conclusion:
Pediatric surgery trainees improved their surgical skills after receiving short-term training. We demonstrated the effectiveness of our training program, which utilized a new laparoscopic fundoplication simulator.
