Neurodevelopmental Outcomes After Neonatal Surgery for Major Noncardiac Anomalies.
2016
CONTEXT: Increasing concerns have been raised about the incidence of neurodevelopmental delay in children with noncardiac congenital anomalies (NCCA) requiring neonatal surgery. OBJECTIVE: This study aimed to determine the incidence and potential risk factors for developmental delay after neonatal surgery for major NCCA. DATA SOURCES: A systematic search in PubMed, Embase and the Cochrane Library was performed through March 2015. STUDY SELECTION: Original research articles on standardized cognitive or motor skills tests. DATA EXTRACTION: Data on neurodevelopmental outcome, the Bayley Scales of Infant Development, and risk factors for delay were extracted. RESULTS: In total, 23 eligible studies were included, reporting on 895 children. Meta-analysis was performed with data of 511 children, assessed by the Bayley Scales of Infant Development at 12 and 24 months of age. Delay in cognitive development was reported in a median of 23% (3%–56%). Meta-analysis showed a cognitive score of 0.5 SD below the population average (Mental Development Index 92 ± 13, mean ± SD; P P LIMITATIONS: All data were retrieved from studies with small sample sizes and various congenital anomalies using different neurodevelopmental assessment tools. CONCLUSIONS: Cognitive and motor developmental delay was found in 23% of patients with NCCA. Meta-analysis showed that the mean neurodevelopmental outcome scores were 0.5 SD below the normative score of the healthy population.
