Heterotopic Gastric Mucosa of the Proximal Esophagus: An Under recognized Entity

Abstract

Heterotopic gastric mucosa (HGM) is an islet of gastric mucosa within the esophageal mucosa. These lesions can sit throughout the digestive tract and rarely in the upper third of the esophagus. The pathophysiology of HGM remains poorly understood.Our study aims to estimate the prevalence of HGM, clinical signs, endoscopic, microscopic aspects and different epidemiological factors associated.All patients from a single endoscopy center with HGM of the upper third of the esophagus were included over a 5-month evaluation period. All lesions seen in endoscopy were confi rmed by histological analysis.The prevalence was 1.3% with a clear male predominance. 80% of patients were symptomatic and received medical treatment, clinical evolution was good. No case of dysplasia was identifi ed and no complication was observed.Due to insuffi cient data in the evolutionary literature, the management of HGM remains debated and could resemble that of Barett's esophagus for monitoring and therapeutic management, particularly in the event of symptoms or dysplasia. Results736 patients underwent gastroscopy during the study period of 5 months, HGM of the proximal esophagus was More Information
