The study investigates the prevalence and epidemiology of congenital diaphragmatic hernia (CDH) using data from European population-based registers between 1980 and 2009.
A total of 3,373 CDH cases were reported, with an overall prevalence of 2.3 per 10,000 births, showing a slight increase over time but no change for isolated cases.
Results indicated significant geographical variation in CDH prevalence, with 69.3% survival to one week for total cases and 72.7% for isolated cases, while maternal age had no significant impact on CDH occurrence.
