Treatment principles: Surgical excision is the mainstay. The treatment plan should be considered according to the patient’s age, presence or absence of symptoms, fertility requirements, nature of polyps, growth rate, etc. Hysteroscopic polypectomy is the main treatment modality, and scraping of small focal or diffuse polyps should be performed with attention to full scraping, especially at the fundus and horn of the uterus. After hysterectomy, anti-infective treatment should be performed. The following aspects need to be noted: 1. In case of concomitant inflammation, the infection should be controlled first. 2. If there is bleeding, stopping the bleeding is the main concern. 3.After the inflammation is controlled, surgery should be performed again. 4.After surgical removal, the polyps should be sent for pathological examination, and if there are signs of malignancy, treatment measures should be taken as soon as possible. 5.The disease is prone to recurrence, and should be reviewed regularly after surgery, once every 3 months.
