The development of gastric cysts is associated with trauma, chemical erosion, and in severe cases, upper gastrointestinal bleeding. Gastric cysts are relatively rare gastric diseases, and the cause of the disease is related to a variety of factors. During the disease, multiple cystic masses appear in the stomach wall, which not only irritate the gastric mucosa but also affect the digestive function of the stomach. The main manifestations of the disease are upper abdominal fullness and discomfort, nausea, vomiting, and loss of appetite. When these symptoms appear, gastroscopy can be used to confirm the diagnosis and treatment should be carried out promptly after the diagnosis is made. If the gastric cyst is not treated in time, in serious cases, it may even lead to gastrointestinal bleeding, and the enlargement of the gastric cyst may also cause pyloric obstruction, which is mainly treated by surgical resection.
