Background The optimal timing of repair for inguinal hernia in premature infants remains a controversial topic. Our objective was to assess the clinical effects of inguinal hernia repair done before or after neonatal intensive care unit (NICU) discharge. Methods MEDLINE, Embase, CINAHL, and CENTRAL were searched in July 2018. Publications comparing clinical outcomes of the premature infants with inguinal hernia repair before (early) and after (delayed) NICU discharge were identified. Two reviewers independently screened studies, extracted data, and assessed for quality. Results were pooled using random effects meta-analysis. Results Of 640 publications identified, six comparative studies assessing a total of 1761 premature infants were included. Meta-analysis indicated no statistically significant difference in incarceration rate (odds ratio (OR) 2.15, 95% confidence interval (CI) 0.83–5.58, I2 = 0%), surgical complications (OR 2.36, 95% CI 0.66–8.41, I2 = 0%) and other secondary complications. However, the odds of recurrence and respiratory difficulty was significantly increase in the early group compared to delayed (OR 4.12, 95% CI 1.17–14.45, I2 = 0%; OR 3.59, 95% CI 1.10–11.75, I2 = 42%). Conclusions Repair of inguinal hernia in premature infants before NICU discharge may increase the odds of recurrence, but not incarceration or surgical complications. Level of evidence Level III
