ABSTRACTIntroduction: The purpose of this study was to determine the transition in the laparoscopic skills of novice surgeons to the level of advanced surgeons using validated drills in a training box.
Materials and methods: A quasi-experimental study of 10 pediatric surgical residents was designed. Residents with previous endoscopic surgical experience equal to or less than five laparoscopic procedures were included. They repeated the MISTELS, Southwestern and García-Ruiz drills untilthe achievement of a validated performance score for advanced surgeons in 5 consecutive repetitions.
Results: The studied group required 12 ± 9 (2-60) repetitions to achieve the specified performance score in the whole set of drills. For the intracorporeal knotting drill they required 11 ± 4 (2-34) repetitions, having a time improvement from 155 to 61 seg (p=0.01); for the extracorporal knotting drill, they required16 ± 7 (4-29) repetitions, with a time improvement from 117 to 46 seg (p=0.002); and for the continuous intracorporeal suture, they required 14 ± 6 (2-23) repetitions and a timing from 559 to 180 seg (p=0.002).
Conclusion: After a mean of 12 repetitions, our residents developed skills that Hill probable improve patients security in their first laparoscopic procedures in children.
