Anti-reflux surgery in children with congenital diaphragmatic hernia: A prospective cohort study on a controversial practice

•What is currently known about this topic? Gastro-esophageal reflux disease affects 50% of children born with congenital diaphragmatic hernia (CDH). No guidelines exist on the use of anti-reflux surgery in these children, and performing preventive fundoplication when performing a diaphragmatic patch repair remains controversial.•What new information is contained in this article? Children with a CDH patch repair have a higher risk of undergoing curative fundoplication. However, performing a preventive fundoplication during the initial CDH repair does not decrease the need for curative fundoplication but increases the rates of failure to thrive, tube feed supplementation, and oral aversion.
