Where is the gastric antrum located in the stomach?

People in modern society obviously know more about various parts of the human body than people in modern society, which is mainly due to the rise of the Internet industry. Now people can learn about the various structures and organs of the human body and even learn about more diseases through the Internet without leaving home. This can obviously prepare for a healthy life in the future. So, do you know where the gastric antrum is located in the stomach?

The gastric antrum is part of the stomach structure. The "gastric antrum" clinically referred to as the pyloric antrum or the pyloric part including the pylorus. Gastric ulcers and gastric cancer often occur in the pyloric antrum near the lesser curvature of the stomach.

definition

The "gastric antrum" clinically referred to is the pyloric antrum or the pyloric part including the pylorus.

Morphological distribution

The pyloric part is the part between the lower limit of the gastric body and the pylorus. There is an inconspicuous shallow groove on the greater curvature of the pyloric part - the middle groove, which divides the pyloric part into the pyloric canal on the right and the pyloric antrum on the left.

Gastric antrum: The gastric antrum refers to the part between the pylorus and the notch of the gastric angle.

Gastric body: The part below the fundus is the gastric body, with the greater curvature on the left and the lesser curvature on the right. The lesser curvature of the stomach suddenly turns right vertically downward, and the junction between them is the angular notch. The line connecting the angular notch to the corresponding greater curvature of the stomach is its lower boundary. The gastric body occupies the largest area and contains most of the parietal cells. Cardia: The junction of the esophagus and stomach, on the left side of the 11th thoracic vertebra, its proximal end is the lower esophageal sphincter, located 2-3cm below the esophageal hiatus of the diaphragm, and in the same plane as the seventh costal cartilage sternal joint. Fundus: The uppermost part of the stomach, located above the horizontal line from the cardia to the greater curvature of the stomach. The upper boundary of the gastric fundus is the diaphragm, the outer side of which is the spleen, and the left side of the esophagus and gastric fundus is the His angle.

About the treatment of indigestion symptoms

Since there is no clear relationship between clinical symptoms and chronic non-atrophic gastritis, symptomatic treatment is actually empirical treatment of functional dyspepsia. Patients with chronic gastritis and bile reflux can use prokinetic drugs (such as domperidone) and/or gastric mucosal protective agents that have the function of binding bile acid (such as aluminum carbonate magnesium preparations). For patients with gastric mucosal erosion and/or symptoms such as acid reflux and upper abdominal pain, antacids, H2 receptor antagonists or proton pump inhibitors (PPIs) can be used according to the severity of the disease or symptoms. Prokinetic drugs such as domperidone, mosapride and itopride hydrochloride can be used for patients with upper abdominal fullness, nausea or vomiting as the main symptoms. Gastric mucosal protective agents such as sucralfate, rebamipide, teprenone, gefarnate, ecabet and aluminum carbonate are suitable for people with bile reflux, gastric mucosal damage and/or obvious symptoms. Antidepressants or antianxiety drugs can be used for patients with chronic gastritis and dyspepsia symptoms with obvious psychiatric factors. Traditional Chinese medicine treatment can broaden the treatment options for chronic gastritis. In addition to their symptomatic therapeutic effects, the above-mentioned drugs may also have certain effects on gastric mucosal epithelial repair and inflammation.
