Is It Barrett's Esophagus or Gastric Heterotopia?

Abstract:
Columnar epithelium in the distal part of the esophagus is generally related to Barrett's esophagus. Barrett's esophagus is a well-known premalignant lesion for adenocarcinoma of the esophagus. Therefore, its diagnosis and surveillance are important. Columnar epithelium in the esophagus other than Barrett's esophagus can be gastric heterotopia, which generally takes place in the upper part of the esophagus and is named inlet patch. The presence of gastric metaplasia in the distal part of the esophagus is rare and can cause misdiagnosis. Therefore, its differentiation from Barrett's esophagus is important. Here we present a case of gastric heterotopia located in the distal part of the esophagus that caused reflux-like symptoms and needed differentiation from Barrett's esophagus.

Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
