Eosinophilic Esophagitis (EoE) is a chronic inflammatory disease characterized by eosinophilic infiltration of the esophageal mucosa, leading to symptoms of dysphagia and food impaction. Currently, upper endoscopy with biopsy is the gold standard for diagnosis and disease monitoring, but it is invasive, costly, and associated with procedural risks. The investigators want to use ultrasound imaging as a non-invasive assessment of esophageal wall thickness as a surrogate marker for mucosal inflammation.
Participants will undergo ultrasound assessment at the same day of endoscopy, and than after 3-6 months (optional). The correlation between US-measured esophageal thickness and histological eosinophil counts will be measured.
Age ≥18 years.
Suspected or confirmed diagnosis of EoE based on clinical symptoms (e.g., dysphagia, food impaction).
