The gastric angle is the gastric lesser curvature at the lowest end of the angle to form all traces, is 90 ° turn, is the gastric body and the pylorus in the gastric lesser curvature of the division, the gastric lesser curvature in the upper right edge of the stomach, the gastric angle is in the gastric lesser curvature of the turn. The right edge of the gastric angle connection, that is, the small bend side is relatively straight, the left side and the gastric fundus between the formation of the incision, in the living body incision deeper into a sharp angle, that is, the esophageal gastric angle or cardia incision, the angle between 70-110 °. The gastric angle is not palpable by abdominal palpation and has no specific location in the projection of the human body. The junction with the gastric body and the gastric sinus at the side of the gastric lesser curvature is called the gastric angle, which mainly has a distinct curvature, that is, a distinct crease and forms a pinch. It occurs at the location of the gastric sinus and the migrating band of the gastric body and is prone to gastric ulcers or gastric cancer, as well as the possibility of recurrent erosions or atypical hyperplasia due to H. pylori infection.
