Cardia polyps are very common in clinic. Pancreatic polyp is mostly due to mucosal epithelial hyperplasia and limited elevated lesions, with a tendency of malignant transformation, especially adenomatous polyp is more common, which can lead to gastrointestinal bleeding, and is extremely harmful to human health. If cardia polyps are not treated in time, they may become malignant. Currently, we advocate early resection and gastroscopic treatment of cardia polyps, including high-frequency electrocoagulation and electrocautery, ligation, etc., which is effective and convenient, and can prevent further cancerous transformation of the polyps, while other treatments include microwaves, lasers, freezing, radiofrequency, etc. Therefore, once a cardia polyp is detected, the patient should be treated as soon as possible. Therefore, once cardia polyps are detected, patients must be treated as soon as possible to avoid delaying the condition.
