Barrett's esophagus is a condition in which there is an abnormal (metaplastic) change in the mucosal cells lining the lower portion of the esophagus, from stratified squamous epithelium to simple columnar epithelium with interspersed goblet cells that are normally present only in the small intestine and large intestine.
Some people also experience a sensation known as globus esophagus, where it feels as if a ball is lodged in the lower part of the esophagus. The following are additional diseases and conditions that affect the esophagus: Achalasia [1] Acute esophageal necrosis; Barrett's esophagus; Boerhaave syndrome; Caustic injury to the esophagus; Chagas disease
Intestinal metaplasia is the transformation of epithelium (usually of the stomach or the esophagus) into a type of epithelium resembling that found in the intestine.In the esophagus, this is called Barrett's esophagus.

Esophageal rupture, also known as Boerhaave syndrome, is a rupture of the esophageal wall. Iatrogenic causes account for approximately 56% of esophageal perforations, usually due to medical instrumentation such as an endoscopy or paraesophageal surgery. [1]
An upper endoscopy is a procedure to look at the esophagus by using an endoscope. While looking at the esophagus, the doctor is able to take a small biopsy. The biopsy can be used to confirm inflammation of the esophagus. An upper GI series uses a barium contrast, fluoroscopy, and an X-ray. During a barium X-ray, a solution with barium or pill ...
Esophageal strictures – the persistent narrowing of the esophagus caused by reflux-induced inflammation; Barrett's esophagus – intestinal metaplasia (changes of the epithelial cells from squamous to intestinal columnar epithelium) of the distal esophagus [20] Esophageal adenocarcinoma – a form of cancer [17]
The most common example of metaplasia is Barrett's esophagus, when the non-keratinizing squamous epithelium of the esophagus undergoes metaplasia to become mucinous columnar cells, ultimately protecting the esophagus from acid reflux originating in the stomach. If stress persists, metaplasia can progress to dysplasia and eventually carcinoma ...
