The cardia of the stomach is the junction of the esophagus and the stomach and is the entrance of food from the esophagus into the stomach.
The cardia can be positioned on the body surface at the lower edge of the body of the sternum, near the posterior aspect of the seventh costal cartilage, to the left of the body of the eleventh thoracic vertebrae, and about 40 centimeters from the middle incisor. The cardia mainly connects the stomach and esophagus, and extends downward into the fundus and body of the stomach, which can secrete abundant mucus, which is helpful for promoting the transportation of food to the stomach while lubricating the gastric mucosa, protecting the digestive tract, and also preventing the reflux of food from the stomach into the esophagus.
When discomfort such as burning and pain occurs in the cardia, it is necessary to be alert to the possibility of digestive system diseases such as carditis and esophageal cancer.
It is recommended that the patient should be admitted to the hospital in time to improve the abdominal ultrasound, upper gastrointestinal barium meal, gastroenteroscopy and other related examinations, so as to clarify the cause of the disease in time and standardize the treatment, and to avoid the adverse consequences.
