Abstract

Insights

Minimally invasive surgery (MIS) for congenital diaphragmatic hernia (CDH) repair significantly reduces the long-term risk of small bowel obstruction (SBO). MIS approaches offer a safer alternative for pediatric CDH repair compared to open surgery.

Area of Science:

  • Pediatric Surgery
  • Surgical Outcomes
  • Gastrointestinal Surgery

Background:

  • Minimally invasive surgery (MIS) for congenital diaphragmatic hernia (CDH) repair offers benefits like shorter hospital stays and improved aesthetics.
  • While MIS is linked to reduced long-term small bowel obstruction (SBO) in adults, its impact on pediatric CDH repair outcomes is less clear.

Purpose of the Study:

  • To compare the rates of small bowel obstruction (SBO) following open versus minimally invasive surgery (MIS) for congenital diaphragmatic hernia (CDH) repair in pediatric patients.

Main Methods:

  • A retrospective analysis of pediatric patients who underwent CDH repair between 2010 and 2021 was conducted using the PearlDiver Mariner database.
  • Kaplan-Meier curves and Cox proportional hazards models were employed to assess the time to SBO, adjusting for mesh use, sex, and length of stay.

Main Results:

  • The study included 1033 patients, with 25.0% undergoing MIS repair. The overall SBO rate was 7.5%.
  • Rates of SBO were consistently lower for MIS compared to open repair at 1, 3, and 5 years post-surgery (P=0.004).
  • Adjusted analysis confirmed that MIS repair was associated with a significantly lower rate of SBO (adjusted hazard ratio: 0.37).

Conclusions:

  • Minimally invasive surgery (MIS) approaches are associated with reduced long-term rates of small bowel obstruction (SBO) after congenital diaphragmatic hernia (CDH) repair.
  • The long-term risk of SBO should be a key consideration when selecting the surgical approach for pediatric CDH patients.
