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
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]
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.
People with Barrett's esophagus (a change in the cells lining the lower esophagus) are at much higher risk, [55] and may receive regular endoscopic screening for the early signs of cancer. [56] Because the benefit of screening for adenocarcinoma in people without symptoms is unclear, [2] it is not recommended in the United States. [1]
Esophagitis is an inflammation of the esophagus, most commonly caused by gastroesophageal reflux disease . [6] It is defined by the sensation of "heartburn" or a burning sensation in the chest as a result of inappropriate relaxation of the lower esophageal sphincter at the site where the esophagus connects to the stomach. It is often treated ...
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 ...
Normally the human gastrointestinal tract digests and absorbs dietary nutrients with remarkable efficiency. A typical Western diet ingested by an adult in one day includes approximately 100 g of fat, 400 g of carbohydrate, 100 g of protein, 2 L of fluid, and the required sodium , potassium , chloride , calcium , vitamins , and other elements.
