Gastric cardia polyps of 0.5~0.6cm usually need to be resected, usually by gastroscopic polypectomy or ligation. When the cardia polyp is small, there is usually no symptom, and it is usually found during gastroscopy. However, as the polyp grows, the patient often has hidden pain in the upper abdomen, bloating and indigestion, etc. Moreover, cardia polyp has the possibility of malignant transformation, so it is usually treated by surgical resection. Cardia polyps with a diameter of 0.3cm or less generally do not require surgical treatment, and it is recommended that they be temporarily observed and regularly rechecked. For polyps with a diameter of more than 0.5cm and less than 2cm, polypectomy can be performed under an electronic gastroscope. Polyps larger than 2cm in diameter are often treated with surgical resection. When cardia polyps appear, it is recommended to consult a doctor in time and treat under the guidance of a professional doctor to avoid delaying the condition.
