Background: Theeosinophilic infiltrate of the esophagus mucosal distinguishes the esophageal ailment known as Eosinophilicesophagitis (EoE). This study aims to determine the frequency of EoE in patients with gastroesophageal reflux disease (GERD), a gastro esophageal reflux condition that is persistent. Methods: The 248 children in total hadelectiveupper gastrointestinal endoscopy (UGIE) during the study period were separated in tosix groups: individuals without a history of steroid usage and those with outanesophageal biopsyforthrombocytopenia. As a result, 200 people participated in the study total. Results: After an evaluation of 200 children having elective UGIE, A variety of health problems were found during the investigation, including food bolusimpact (2 %), achalasia cardia (5 %), pepticstricture (6 %), congenitalstricture (3 %), post-esophageal atresia repairanastomoticstricture (4 %), and symptoms of gastro esophageal reflux, including vomiting (10 %), regurgitation (2 %), belchingchest (1,5 %), nocturnal cough (2,5 %), pain/heartburn (12,5 %), and feeding refusal (1 %). There were several unusual illnesses that were observed, including Crohn's disease accounted for 2 %, paediatric intestinal pseudo-obstruction (10 %), abdominal discomfort (17,5 %), celiacdisease (16 %), cow's milk protein allergy (3 %), and un classified IBD (7 %). Conclusion: EoEfrequently affects GERD patients who are recalcitrant to treatment. Dysphagia, food impaction, and heartburn are posible symptoms. EGD and esophageal biopsy should be explored for EoEscreening in elderly individuals with strong GERD who are atopy positive and who have not responded to gastric acid inhibitors.
