Background and Objectives: The initial diagnostic test required to evaluate esophageal dysphagia is upper endoscopy (EGD) to assess the structure of the esophagus and the esophageogastric junction (EGJ). Taking biopsies during EGD has become a common practice in patients with dysphagia to rule out eosinophilic esophagitis (EoE). The aims of this study were to evaluate the endoscopic findings of patients who underwent EGD for esophageal dysphagia, to assess the rate of biopsy taking from the esophagus to diagnose/exclude EoE, and to report histology outcomes of these biopsies. Materials and Methods: This was a retrospective multicenter study that included individuals ≥18 years who underwent EGD due to esophageal dysphagia between the years 2015 and2020, (with no other alarm signs, such as weight loss, new iron deficiency anemia, and lymphadenopathy). We obtained data from patients’ electronic files. The endoscopy and histology findings were obtained from endoscopy reports saved in our electronic files. Results: A total of 209 patients were included in the study. The average age was 57.1 ± 17.1 years. The most common endoscopic findings were normal endoscopy in 76 patients (36.4%) and erosive esophagitis in 75 patients (35.9%). Barrett’s esophagus and esophageal malignancy were encountered in 11 patients (5.3%) and 2 patients (0.95%), respectively. Esophageal biopsies were taken in 50.2% of patients, and one patient had histological evidence of EoE (0.5%). On univariate analysis, there was a trend for association between proton pump inhibitors (PPIs) use and a normal EGD, but it was not statistically significant (OR 0.28, 95% CI 0.07–1.11, p = 0.07). Conclusions: Endoscopic findings were prevalent in dysphagia patients even when no other alarm symptoms exist. Neoplastic lesions and EOE were rare in our study.
