Retrospective analysis examines learning curve, operative times, and safety in pediatric surgery, focusing on preterm infants.
Key Points
To assess the learning curve and safety profile of laparoscopic intracorporeal sac transection with purse-string suture (LIST-PS) in pediatric patients.
Retrospective analysis of 469 pediatric patients
Learning curve assessed using cumulative sum (CUSUM) analysis of operative times
Cohort divided into learning and proficiency phases
Comparison of high-risk subgroup (preterm infants) with control group
Mean operative time decreased from 70.6 min in phase 1 to 52.0 min in phase 2
Recurrence rate stable at 1.7% across phases
High-risk subgroup required longer operative times with no significant difference in recurrence compared to control group
