Diagnostic Methods in Eosinophilic Oesophagitis: From Endoscopy to the Future

Eosinophilic oesophagitis (EoE) is an increasingly prevalent disease in clinical practice. Nowadays it is the most frequent cause of dysphagia in young patients and the second leading cause of chronic oesophagitis. The gold standard technique for diagnosis and monitoring the disease is oesophagoscopy with biopsies, which is not without complications. Due to the lack of consensus on the monitoring of the disease, and the rise of dietary therapies, there has been a significant increase in the number of endoscopies per patient (up to ten). At the present time, non-invasive methods are being developed that make the management of these patients a less invasive and more sustainable strategy.
