The pylorus is considered as having two parts, the pyloric antrum (opening to the body of the stomach) and the pyloric canal (opening to the duodenum). The pyloric canal ends as the pyloric orifice, which marks the junction between the stomach and the duodenum. The orifice is surrounded by a sphincter, a band of muscle, called the pyloric ...
Antrectomy removes gastrin-producing G-cells in the stomach antrum, in turn reducing gastric acid levels. Gastric cancer: Antrectomy could remove gastric tumors developing in the antrum. [1] Gastric antral vascular ectasia syndrome (GAVE): The disease is characterized by excessive bleeding in the stomach. By removing the bleeding site and ...
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 .

Antrum follicularum, the cavity in the epithelium that envelops the oocyte; Mastoid antrum, a cavity between the middle ear and temporal bone in the skull; Stomach antrum, either Pyloric antrum, the lower portion of the stomach. This is what is usually referred to as "antrum" in stomach-related topics [citation needed]
Replacing animal-based food such as red and processed meat or eggs with plant-based options such as nuts or legumes may reduce the risk of developing heart disease and type 2 diabetes, a ...
On the other hand, increased acid production at the pyloric antrum is associated with duodenal ulcers in 10% to 15% of H. pylori infection cases. In this case, somatostatin production is reduced and gastrin production is increased, leading to increased histamine secretion from the enterochromaffin cells, thus increasing acid production
The pylorus opens to the body of the stomach. The pylorus (from Greek 'gatekeeper') connects the stomach to the duodenum at the pyloric sphincter. The cardia is defined as the region following the "z-line" of the gastroesophageal junction, the point at which the epithelium changes from stratified squamous to columnar. Near the cardia is the ...
