Abstract

Purpose: Neurodevelopmental disorders (ND) have been recognized as the most common and potentially most disabling outcome of congenital diaphragmatic hernia (CDH). Our aim was to evaluate the incidence of ND in patients with a history of CDH referred for ND assessment on the basis of clinically relevant symptoms rather than through a screening process.

Methods: The study was a nationwide, population-based prospective nested case-control study within a cohort of newborn children who survived the newborn period in Sweden during the observational period from 1st January 1982 until 31st December 2015.

Results: In the study period, 641 non-syndromic CDH survivors were identified, and 3080 control cases were selected. Significantly higher incidence of clinically relevant any ND (11.5% vs 5.6%,p < 0.001), ASD (3.9% vs 2.1%,p:0.011), and intellectual disorder (6.6% vs 0.7%,p < 0.001) were observed in CDH compared to controls. When compared with controls, those with CDH were found to have a 2.179 times higher risk to develop any ND (p < 0.001), 1.867 times higher risk for ASD (p = 0.008), and 10.63 times higher for intellectual disorder (p < 0.001).

Conclusion: CDH survivors have a higher risk of clinically relevant ND than the general population, independent of the effect of screening.
