In brief
In brief
Systematic review comparing early versus delayed inguinal hernia repair in preterm infants. Early repair reduces incarceration risk but increases postoperative respiratory complications. Timing decisions should be individualized based on patient physiology and family discussion.
- Early repair (before NICU discharge) reduces incarceration risk by 57% compared to delayed repair in preterm infants.
- Early repair increases postoperative respiratory complications 4-fold versus delayed approach.
- No significant difference in recurrence or surgical complication rates between early and delayed repair timing.
- Optimal timing requires individualized risk-benefit discussion balancing incarceration risk against respiratory vulnerability.
- Decision should account for patient physiology, postmenstrual age, and family circumstances rather than protocol alone.

Key findings are presented in bullet points with statistical values, and a yellow conclusion banner spans the bottom.

Objectives
To evaluate the clinical outcomes of herniotomy in preterm infants undergoing early versus delayed repair, the risk factors for complications, and to identify best timing of surgery.
Methods
Medline, Embase and Central databases were searched from inception until 25 Jan 2021 to identify publications comparing the timing of neonatal inguinal hernia repair between early intervention (before discharge from first hospitalization) and delayed (after first hospitalisation discharge) intervention. Inclusion criteria was preterm infants diagnosed with inguinal hernia during neonatal intensive care unit admission. Results were analyzed using fixed and random effects meta-analysis (RevManv5.4).
Results
Out of 721 articles found, six studies were included in the meta-analysis. Patients in the early group had lower odds of developing incarceration [odds ratio (OR) 0.43, 95% confidence interval (CI) 0.34–0.55, I2 = 0%, p < 0.001]; but higher risk of post-operative respiratory complications (OR 4.36, 95% CI 2.13–8.94, I2 = 40%, p < 0.001). No significant differences were reported in recurrence rate (OR 3.10, 95% CI 0.90–10.64, I2 = 0%, p = 0.07) and surgical complication rate (OR 0.94, 95% CI 0.18–4.83, I2 = 0%, p = 0.94) between early and delayed groups.
Conclusion
While early inguinal hernia repair in preterm infants reduces the risk of incarceration, it increases the risk of post-operative respiratory complications compared to delayed repair. Surgeons should discuss the risks and benefits of delaying inguinal hernia repair with the caregivers to make an informed decision best suited to the patient physiology and circumstances.
