Gastric antral vascular ectasia (GAVE) is an uncommon cause of chronic gastrointestinal bleeding or iron deficiency anemia. [ 1 ] [ 2 ] The condition is associated with dilated small blood vessels in the gastric antrum , which is a distal part of the stomach . [ 1 ]
Recent research has shown that autoimmune metaplastic atrophic gastritis (AMAG) is a result of the immune system attacking the parietal cells. [6]Environmental metaplastic atrophic gastritis (EMAG) is due to environmental factors, such as diet and H. pylori infection.
Pyloric antrum 11. Pyloric canal 12. Angular incisure 13. Gastric canal 14. Rugal folds. The pylorus is the furthest part of the stomach that connects to the duodenum. It is divided into two parts, the antrum, which connects to the body of the stomach, and the pyloric canal, which connects to the duodenum. [2]
Gastric ulcers may develop; it is unclear if they are the causes or the consequences. Intestinal metaplasia typically begins in response to chronic mucosal injury in the antrum and may extend to the body.

[1] [2] This is performed using either the Billroth I (BI) or Billroth II (BII) reconstruction method.
Foveolar cells in the antrum of stomach. A skewed cross-section of the columns gives a false impression of being stratified epithelium. Foveolar cells line the surface of the stomach and the gastric pits. They constitute a simple columnar epithelium, as they form a single layer of cells and are taller than their width. Other mucus-secreting ...
Retained antrum syndrome or retained gastric antrum syndrome is one of the rare postgastrectomy syndromes. It happens after Billroth II surgery and the mechanism involved is the inadequate removal of the distal antrum and pylorus during resection of the antrum and gastrojejunostomy .
