The recurrence rate of endometrial polyps, which is still relatively high in clinical practice, is about 8%-35% within two years, probably due to inflammatory stimulation and long-term imbalance of estrogen and progesterone in the body, causing local endometrial proliferative benign lesions. If the endometrial inflammation persists or the hormonal imbalance in the body has been persistent, resulting in long-term irregular menstruation, such endometrial polyps are likely to recur again. At present, patients are advised to undergo hysteroscopic polypectomy, which has a relatively small chance of recurrence. However, for multiple polyps and atypical hyperplastic polyps, the chance of recurrence after surgery is relatively high, and postoperative treatment with progesterone or intrauterine Mannorrhea is often needed to prevent recurrence according to different conditions. It is necessary to go for a postoperative review once a month, then once in three months, and again in the last six months. Because endometrial polyps have a certain chance of malignancy, about 1%, they should also be taken seriously. As endometrial polyps are prone to recurrence, generally the endometrium is often repaired in 1-2 months after the endometrial polyp is removed. Therefore, for women who have fertility requirements, prepare for pregnancy as soon as possible after two months after surgery.
