Diagnostic Value of Ultrasound Findings in Eosinophilic Esophagitis Versus Gastroesophageal Reflux Disease in Children

Background: Eosinophilic esophagitis (EoE) is a disease involving the esophagus due to an immune system reaction and has clinical symptoms similar gastroesophageal reflux (GERD). Currently, only definitive way diagnose this endoscopy biopsy of esophageal tissue. Objectives: In study, we investigated diagnostic value ultrasound differentiate EoE from GERD normal patterns. addition, assessed possibility replacing with invasive endoscopic method for diagnosis follow-up EoE. Methods: This cross-sectional study was conducted on 4-12-year-old children in three groups definitely diagnosed GERD, EoE, healthy controls. Each group consisted 30 participants who were evaluated parameters. The obtained values compared between groups. sensitivity specificity findings determined by receiver operating characteristic curve analysis. Results: Ultrasound findings, including wall thickness distensibility cervical abdominal esophagus, gastric thickness, diameter had significant differences highest mean ± SD 2.73 0.66 mm, 4.30 0.79 2.32 1.21 mm. lowest esophagus. On other hand, area under (AUC) discriminating controls 0.83 0.80 respectively. Moreover, AUCs 0.71 Conclusions: Although significantly different control group, ability discriminate moderate (0.70
