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.
Upper and lower human gastrointestinal tract. The esophagus (American English) or oesophagus (British English, see spelling differences; both / iː ˈ s ɒ f ə ɡ ə s, ɪ-/; pl.: (o)esophagi or (o)esophaguses), colloquially known also as the food pipe, food tube, or gullet, is an organ in vertebrates through which food passes, aided by peristaltic contractions, from the pharynx to the stomach.
t. e. Gastroesophageal reflux disease ( GERD) or gastro-oesophageal reflux disease ( GORD) is a chronic upper gastrointestinal disease in which stomach content persistently and regularly flows up into the esophagus, resulting in symptoms and/or complications. [6] [7] [10] Symptoms include dental corrosion, dysphagia, heartburn, odynophagia ...
Cancer. Esophagitis, also spelled oesophagitis, is a disease characterized by inflammation of the esophagus. The esophagus is a tube composed of a mucosal lining, and longitudinal and circular smooth muscle fibers. It connects the pharynx to the stomach; swallowed food and liquids normally pass through it.

Esophageal rupture 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] The 10% of esophageal perforations caused specifically by vomiting are termed Boerhaave syndrome.
Esophageal webs are thin 2–3 mm (0.08–0.12 in) membranes of normal esophageal tissue consisting of mucosa and submucosa that can partially protrude/obstruct the esophagus. They can be congenital or acquired. Congenital webs commonly appear in the middle and inferior third of the esophagus, and they are more likely to be circumferential with ...
Nutcracker esophagus is characterized as a motility disorder of the esophagus, meaning that it is caused by abnormal movement, or peristalsis of the esophagus. [2] People with motility disorders present with two main symptoms: chest pain or difficulty with swallowing. Chest pain is the more common. The chest pain is very severe and intense, and ...
v. t. e. A mucous membrane or mucosa is a membrane that lines various cavities in the body of an organism and covers the surface of internal organs. It consists of one or more layers of epithelial cells overlying a layer of loose connective tissue. It is mostly of endodermal origin and is continuous with the skin at body openings such as the ...
