Gastric polyps may be associated with Helicobacter pylori infection and chronic gastritis, and their severity is related to the size, number, and histologic type of polyps. Types of polyps such as chorioadenomas, which are more malignant, are more serious. Gastric polyps are lesions that protrude or bulge into the stomach and are mostly hyperplastic and are more common as singular, with a higher rate of multiple malignancies. They may be caused by Helicobacter pylori infection and chronic inflammatory stimulation of the gastric mucosa, leading to excessive regeneration of gastric epithelial cells. 1. Size: With a diameter of about 0.5cm, the polyp is small, and the cancer rate is usually low and the condition is mild. If the diameter is ≥2cm, the condition is more serious and the rate of malignant transformation is higher. 2. Quantity: single polyps are relatively less serious and usually have a low malignancy rate. Multiple cases are relatively more serious and have a higher malignant rate. 3. Histological typing: mainly including stromal tumor, inflammatory and proliferative, and neoplastic. The condition of gastric polyps is mild and the malignant rate is low. On the other hand, neoplastic polyps, such as choriocapillaris adenoma and tubular choriocapillaris adenoma, have a high rate of cancerous transformation. Gastric polyps are asymptomatic in early stage. About half of the patients are accidentally found during barium meal imaging, gastroscopy or surgery for other reasons. The most common symptoms are abdominal discomfort and vague pain. When gastric polyps appear, it is recommended to consult a doctor in time for targeted treatment under the guidance of the doctor.
