An algorithm effectively prevents incomplete pyloromyotomy in laparoscopic surgery for pediatric surgical trainees. This method reduces mucosa perforations without increasing complications in 3-port laparoscopic and laparoendoscopic single-site procedures.

Area of Science:

  • Pediatric Surgery
  • Minimally Invasive Surgery
  • Surgical Education

Background:

  • Pyloromyotomy is a common procedure for infantile hypertrophic pyloric stenosis.
  • Incomplete pyloromyotomy can lead to residual symptoms and reoperation.
  • Laparoscopic techniques, including 3-port laparoscopic (3TP) and laparoendoscopic single-site (LESS-P), are increasingly used.

Purpose of the Study:

  • To analyze an algorithm designed to prevent incomplete pyloromyotomy.
  • To evaluate the algorithm's efficacy in 3TP and LESS-P procedures within a teaching hospital setting.
  • To assess the safety and outcomes of the algorithm in pediatric surgical trainees (PST).

Main Methods:

  • An algorithm defining anatomical margins for pyloromyotomy was implemented.

  • Data on incomplete pylorotomies, mucosa perforations, serosa lacerations, and wound infections were collected.
  • Outcomes were compared between PST and board-certified pediatric surgeons (BC) across 3TP, LESS-P, and open pyloromyotomy (OP) groups.

    • Main Results:

    • No incomplete pylorotomies occurred in any group.
    • Laparoscopic procedures (3TP and LESS-P) showed zero mucosa perforations compared to 6.38% in OP (P=.013).
    • Wound infection rates were similar across all procedures; infections in laparoscopic cases were linked to skin adhesive use.

    Conclusions:

    • The algorithm successfully prevents incomplete pyloromyotomy, particularly during the learning curve for PST.
    • Implementing the algorithm in 3TP and LESS-P procedures is safe and reduces mucosa perforations.
    • The study supports the use of laparoscopic pyloromyotomy in a teaching environment with appropriate algorithmic guidance.
