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 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] The dilated vessels result in intestinal bleeding. [3]
After removal of the distal portion (including the antrum and the pylorus) of the stomach, a clamp is fitted at right angles to the greater curvature. [9] The clamp is pushed far enough orally (towards the mouth) for the removal level to correspond in size to the duodenal lumen. [9]
The stomach is located between the esophagus and the small intestine. The pyloric sphincter controls the passage of partially digested food from the stomach into the duodenum, the first and shortest part of the small intestine, where peristalsis takes over to move this through the rest of the intestines.
The gastric glands are glands in the lining of the stomach that play an essential role in the process of digestion. All of the glands have mucus-secreting foveolar cells (also known as surface mucous cells) that line the stomach and partly line the gastric pits, and mucus-secreting mucous neck cells in the necks of the gastric glands. [1]
The greater curvature of the stomach forms the lower left or lateral border of the stomach. [3] Starting from the cardiac orifice it begins at the cardiac notch, forming an arch backward, upward, and to the left. A horizontal plane across from the cardiac notch encloses an area called the fundus of the stomach.
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]
The operation usually performed is an antrectomy, the removal of the antral portion of the stomach. Other surgical approaches include: vagotomy, the severing of the vagus nerve, the Billroth I, a procedure which involves anastomosing the duodenum to the distal stomach, or a bilateral truncal vagotomy with gastrojejunostomy.
