The gastric antrum is in the lower part of the stomach, connecting the body of the stomach at the upper end and the pylorus at the lower end, and is the part of the stomach between the plane of the gastric angle notch and the pylorus. The gastric sinus is located in the lower part of the stomach and is the main deposition location of gastric acid. Therefore, the gastric sinus is easy to be stimulated by gastric acid, corrosion of gastric mucosa, and is a good site for gastric ulcers, gastritis, and tumors. At the same time, the gastric sinus is close to the pylorus, which is also a susceptible site for Helicobacter pylori infection.
