Transnasal endoscopy for eosinophilic esophagitis surveillance in adolescents with mild autism spectrum disorder: A single‐center case series

JPGN Reports, EarlyView.
Abstract Children with autism spectrum disorder (ASD) often experience sensory sensitivities and procedural anxiety, which can complicate sedated esophagogastroduodenoscopy (EGD). Transnasal endoscopy (TNE) is a less invasive, unsedated alternative, but data on its use in this population are limited.
