Gastric banding

Gastric Antrum

The Gastric Antrum is the final section of the stomach, located before the pylorus, which leads to the duodenum. It plays a crucial role in the digestive process, being responsible for the final stages of digestion before the food passes into the small intestine.

Anatomy

The gastric antrum is located on the lower portion of the stomach. It is surrounded by the body of the stomach on one side and the pylorus on the other. The antrum is lined with gastric mucosa, which contains gastric glands that secrete gastric juice.

Function

The primary function of the gastric antrum is to aid in digestion. It does this by secreting gastric juice, which contains hydrochloric acid and digestive enzymes. These substances help to break down food particles into a semi-liquid substance known as chyme. The antrum also plays a role in the regulation of gastric emptying, controlling the rate at which chyme enters the duodenum.

Clinical Significance

The gastric antrum is often the site of various gastrointestinal disorders, including gastric ulcers and gastritis. These conditions can cause symptoms such as abdominal pain, nausea, and vomiting. In severe cases, they can lead to complications such as bleeding, perforation, and gastric cancer.
