Barrett's esophagus complications

Barrett's esophagus can occur serious complications, benign complications including reflux esophagitis, esophageal stricture, ulcer, perforation, bleeding and aspiration pneumonia.
Common complications of Barrett's esophagus as follow:

1. Barrett esophageal ulcers caused by the incidence of ulcers was 2% ~ 54% of esophageal columnar epithelium by acidic digestive juice corrosion can occur after the ulcer, gastric ulcer like symptoms, pain radiation to be back, and may cause perforation, hemorrhage, infiltration, ulcer healing occurred after the narrow, poor hypopharyngeal symptoms appear. Aortic penetrate even lead to bleeding and rapid death. Barrett's ulcer, there are two pathological types, the most common for the above occurred in the squamous epithelium of superficial ulcers, and because of this type of reflux esophagitis ulcer caused similar. Another for the occurrence of a rare columnar epithelium in the deep section of ulcers, and peptic ulcer is similar.

2. Stricture Barrett esophageal stenosis is the most common esophageal complications, the incidence of 15% to 100%. Narrow parts of the upper esophagus than the scales - at the junction of columnar epithelium, and gastroesophageal reflux-induced esophageal stenosis is located in the following paragraph and more. Reflux esophagitis incidence was 29% ~ 82%. Lesions involving the columnar epithelium alone, can also affect squamous and columnar epithelium.

3. Canceration Barrett esophageal cancer occurred. However, if the purposes of Barrett esophagus patients had anti-reflux surgery does not make these columnar epithelium subsided, nor to reduce the risk of malignant transformation. Barrett esophageal columnar epithelium in the region dysplasia can occur, since the low level of high, low-grade dysplasia is sometimes difficult to distinguish between normal columnar epithelium, a high degree of dysplasia and carcinoma in situ is sometimes difficult to distinguish between, and may progress to invasive carcinoma. These malignant tumor grade adenocarcinoma. Have pointed out that the endoscopic cardia adenocarcinoma was found benign columnar epithelium with columnar epithelial dysplasia and adenocarcinoma is different. Barrett's esophagus dysplasia is a precancerous condition of the majority of people have been recognized.

4. Gastrointestinal bleeding. Can be manifested as hematemesis or hematochezia, and associated with iron deficiency anemia, the occurrence rate of about 45%, the source of bleeding esophagitis and esophageal ulcer.
