How does the number of training years in pediatric surgery affect appendectomy outcomes?

Abstract

Introduction: Appendectomy has traditionally been considered as a training operation for junior pediatric surgeons during their training period. However, with the increase of laparoscopic appendectomy, there has been a growing concern about the performance of this procedure by junior trainees. Our aim is to analyze intra-/postoperative appendectomy outcomes according to the number of training years during Pediatric Surgical residency training program.

Methods: A retrospective study was performed in patients who underwent appendectomy between 2018 and 2021 in our institution, who were divided into 5 groups according to the number of training years of the junior surgeon who performed the intervention (Y1-Y5). Demographics, complicated appendicitis rate, operation time, and postoperative complications were compared. A stratified analysis according to the technique performed (open/laparoscopic) was performed.

Results: A total of 1274 appendectomized patients were analyzed, of which 1257 (98.7%) were operated on by junior trainees (81 in Y1; 407 in Y2; 337 in Y3; 261 in Y4; and 171 in Y5) without demographic differences between groups. As the year of training increased, an elevation in complicated appendicitis rate was observed, although without statistically significant differences. However, laparoscopic/open appendectomies ratio increased with increasing year of training (p < 0.001). Operative time decreased significantly with increasing year of training (p < 0.001), both in open and laparoscopic appendectomies. There were no significant differences in postoperative complications, nor in the stratified analysis according to surgical technique.

Conclusion: Appendectomy performed by junior pediatric surgery trainees can be considered a safe procedure from the first year of training, regardless of the technique used.
