Barrett's esophagus is a pre-malignant condition, not a cancerous one. [citation needed] A small subset of patients with Barrett's esophagus will eventually develop malignant esophagogastric junctional adenocarcinoma, which has a mortality rate of over 85%. [45]
Although H. pylori infection can cause gastrointestinal metaplasia, its eradication does not reverse the process. [1] Bile reflux is an additional pathogenic factor in gastrointestinal metaplasia that can continuously irritate the gastric mucosa. Bile acids in refluxed fluid are widely reported to be associated with gastrointesinal metaplasia ...
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]
Esophageal inlet patches are well defined areas of mucosa which resemble stomach tissue and are pink or salmon colored. [2] The mucosal surface of an esophageal inlet patch is typically flat, [3] but may be slightly raised or slightly depressed.
Barrett's esophagus is the dominant pre-malignant lesion of esophageal adenocarcinoma, [18] and has prevalent epigenetic alterations. [ 19 ] Esophageal squamous-cell carcinomas may occur as second primary tumors associated with head and neck cancer , due to field cancerization (i.e. a regional reaction to long-term carcinogenic exposure).
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]

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 ...
