The pancreatic blockage is related to pancreatitis, pancreatic tumor, esophageal hiatal hernia and other factors. First of all, when the mucosa of the cardia is edematous and congested, excessive secretion of gastric acid will cause irritation to the mucosa of the cardia, which will not only be accompanied by cardia blockage, but also symptoms such as burning and pain in the sternum. Secondly, once a tumor appears in the cardia, the tumor will invade the tissues around the anus and affect the passage of food, resulting in a feeling of cardia blockage, and many patients will have difficulty swallowing at the same time. The esophageal hiatal hernia is especially likely to appear in the cardia, which causes the organs in the abdominal cavity to enter the thoracic cavity through the esophageal hiatal hernia, and many people will have epigastric fullness, cardia blockage, belching, pain and other manifestations during the disease, and surgery should be performed if necessary.
