Objectives: To observe the frequency of eosinophilic esophagitis (EoE), pattern of clinical presentation and diagnosis among Saudi children at 2 tertiary care hospitals in Riyadh, Saudi Arabia. Methods: The database of children admitted or seen, and aged less than 18 years over 5 years period and diagnosed with EoE was collected and reviewed. Patients with esophagitis other than EoE were excluded. Patients who had eosinophils count more than 15/high power field (HPF) on esophageal biopsies were given the diagnosis of EoE. Demographic database, clinical parameters, and diagnostic modalities were analyzed by using the Statistical Package for Social Sciences version 22. Results: A total of 37 children with the diagnosis of EoE were gathered from 398 upper gastrointestinal endoscopic procedures with the frequency of 9.3%. There were 22 (59.4%) males with a mean±SD age of 9.6±2.3 years and all were Saudi nationals. Dysphagia was the leading presentation in 21 (56.7%) children followed by vomiting in 18 (48.6%), impaction of food bolus in 8 (21.6%) and foreign body in 3 (8.1%). Allergic symptoms were present in 13 (35.1%) children in the form of asthma, 11 (29.7%) multiple food allergies and 5 (13.5%) eczema. Peripheral eosinophil count and immunoglobulin E were raised more than normal in 6 and 5 children respectively. The pH measurements were carried out in 16 (43.2%) and ruled out the reflux. Contrast studies with barium (n=6; 16.2%) and endoscopic findings were significant (n=27; 72.9%). Conclusion: Eosinophilic esophagitis is an emerging disease and have a rising trend in Saudi children. Dysphagia, vomiting, and food impaction are the more common presenting features in older children and recurrent vomiting in younger children in addition to associated allergic conditions.
