Does timing of neonatal inguinal hernia repair affect outcomes?

Area of Science:

• Pediatric Surgery
• Neonatal Care
• Health Services Research

Background:

• Neonatal inguinal hernia (IH) is a common condition requiring surgical intervention.
• The optimal timing for neonatal inguinal hernia repair (IHR) remains a subject of clinical debate.
• Variability in surgical practice can impact patient outcomes.

Purpose of the Study:

• To investigate practice variations in the timing of neonatal inguinal hernia repair (IHR).
• To compare clinical outcomes between early and delayed IHR in neonates.
• To identify factors associated with different repair timings.

Main Methods:

• Retrospective analysis of 2030 neonatal intensive care unit patients diagnosed with IH from 1999-2011.
• Categorization of IHR as early (during index hospitalization) or delayed (after index hospitalization).
• Propensity score matched analysis to control for baseline differences between early and delayed repair groups.

Main Results:

• 32.9% of neonates underwent delayed IHR, with significant inter-hospital variability (p<0.0001).
• Delayed repair was associated with higher rates of congenital anomalies and life support measures (p<0.01).
• Incarceration at repair occurred in 8.2% of delayed repairs; early repair had higher reoperation rates within 1 year (5.9% vs. 3.7%, p=0.02).

Conclusions:

• Significant practice variability exists in the timing of neonatal inguinal hernia repair across children's hospitals.
• Delayed IHR is associated with a higher risk of incarceration at the time of surgery.
• Early IHR is associated with an increased rate of reoperation within the first year post-surgery.
