The pylorus is the part where the stomach and esophagus meet. It is the passage at the upper end of the stomach. Food in the esophagus enters the stomach through the pylorus. There are muscles on the pylorus that can contract and relax to prevent food and gastric juice that enter the stomach from backflowing into the esophagus. Relaxation of the cardia can cause erosion and inflammation of the esophagus. Cardiac cancer can cause food obstruction and inability to swallow, and patients need timely treatment.

The esophageal mucosa is connected to the gastric mucosa at the pylorus. The expansion of the lower esophagus here can tighten the upper opening of the stomach, preventing the stomach contents from returning to the esophagus during gastric peristalsis, thereby preventing gastric juice from burning the esophageal cavity (the gastric mucosa itself is acid-resistant). In a normal body, even when lying flat or upside down, the contents of the stomach will not reflux into the esophagus, which is also due to the expansion of the lower esophagus. Some babies are prone to vomiting when lying down after drinking milk. One of the reasons is that the pyloric muscle is relatively weak.

The treatment of pyloric disease also needs to be determined based on the actual cause and characteristics of the underlying disease. The main common pyloric diseases include cardia inflammation, cardia cancer, cardia polyps and so on. In clinical medicine, cardia inflammation is generally treated with medication. Common medicines include proton pump retarder, H2 blocker, gastric mucosal protective film or antacid. If Helicobacter pylori infection exists, triple or quadruple standard treatment should also be used.

Cardiac polyps are generally treated with endoscopic polypectomy, and submucosal removal can also be used if necessary. Once cardiac cancer is confirmed, different treatment plans should be selected based on the actual installment. Surgical treatment is preferred, including proximal subtotal gastrectomy, total gastrectomy, and palliative gastrectomy. After the operation, it is necessary to decide whether further comprehensive treatments such as radiotherapy and chemotherapy are needed based on the actual pathological condition.
