Esophagus lower abnormal columnar epithelium, called Barrett esophagus. Universal is acquired, and the flowing esophagitis, and closely related with adenocarcinoma.In 1950, Norman Barrett first proposed in 1957, already gradually for the people concerned. Barrett's esophagus endoscopic diagnosis, it is generally thought that must be dealt with at least from stomach esophagus than 3cm the columnar epithelium, Barrett said esophagus covered. Barrett's esophagus also somebody thinks, because of congenital fetal period of columnar epithelium, esophagus squamous replacement by. Ectopic columnar epithelium residues in any part of the esophagus esophagus can occur.
Barrett esophagus age 1 months from birth to age 88 have report, a double peak age distribution curve, the first summit in 0 ~ 15 years old, another peak in 48 ~ 80 years old, but in clinical and elderly. Barrett esophageal onset of male men and women in the ratio of 3:1 ~ 4:1. Only the lower esophagus patients columnar epithelium metaplasia usually asymptomatic, most patients can never appear symptoms. Barrett esophageal symptoms gastroesophageal reflux is mainly caused by the complications and gastroesophageal reflux, retrosternal voiding symptoms of chest pain, nausea, and clinical appearance typical heartburn and nausea just go to a doctor, because of esophageal cancer or narrow part appears headed by swallowing dre manifestations.Difficulty swallowing reason is:
1,scale - columnar epithelium of the junction stricture,
2,due to chronic esophagitis pipe fibrosis, esophageal motility impairment,
3,caused by esophageal acute inflammation of the esophagus convulsion,
4, in columnar epithelium with esophageal adenocarcinoma of lumen obstruction. Some patients have heartburn, the early symptoms of a long time, until symptom-free period before symptoms appear complications, the reason is columnar epithelium to stimulate digestive as squamous epithelium sensitive. Barrett esophageal bleeding can be large, but often a chronic iron-deficiency anaemia. A hole or invading pleural cavity or into other nearby caused fistula organs appear symptoms.
