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.
The esophagus should be checked every year or two with a timed barium swallow because some may need pneumatic dilatations, a repeat myotomy, or even esophagectomy after many years. In addition, some physicians recommend pH testing and endoscopy to check for reflux damage, which may lead to a premalignant condition known as Barrett's esophagus ...
Barium swallow X-rays should not be used for diagnosis. [42] Esophageal manometry is not recommended for use in the diagnosis, being recommended only prior to surgery. [42] Ambulatory esophageal pH monitoring may be useful in those who do not improve after PPIs and is not needed in those in whom Barrett's esophagus is seen. [42]
Acute esophageal necrosis (AEN), black esophagus, or Gurvits syndrome is a rare esophageal disorder. AEN defines itself with dark pigmentation of the esophagus, found during an upper gastrointestinal endoscopy. [2] Pigmentation is usually black friable mucosa. [3]
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] The 10% of esophageal perforations caused specifically by vomiting are termed Boerhaave ...
This phenomenon, known as Barrett's esophagus, seems to appear about 20 years later in women than in men, possibly due to hormonal factors. [26] At a mechanistic level, in the esophagus there is a small HOXA13 expressing compartment that is more resistant to bile and acids as the normal squamous epithelium and that is prone to both intestinal ...
If it is caused by esophagitis, in turn caused by an underlying infection, it is commonly treated by treating the infection (typically with antibiotics). In order to open the stricture, a surgeon can insert a bougie – a weighted tube used to dilate the constricted areas in the esophagus. [3] It can sometimes be treated with other medications.
Heller myotomy is a surgical procedure [1] in which the muscles of the cardia (lower esophageal sphincter or LES) are cut, allowing food and liquids to pass to the stomach.It is used to treat achalasia, a disorder in which the lower esophageal sphincter fails to relax properly, making it difficult for food and liquids to reach the stomach.
