The Role of Transnasal Endoscopy in Diet Management of Eosinophilic Esophagitis

The diagnosis and monitoring of eosinophilic esophagitis (EoE) relies on clinical symptoms and histological examination of the esophageal mucosa. Currently, esophagogastroduodenoscopy with biopsy is the standard of care in the diagnosis and monitoring of EoE. Unsedated transnasal endoscopy (TNE) is a less invasive and less costly procedure that can be performed without general anesthesia. Here, we describe the first case of a 15-year-old adolescent girl who underwent TNE exclusively to identify all food triggers for EoE. She underwent 12 TNEs over a period of 4 years to identify food triggers for EoE to ultimately achieve the remission of her disease.
