If the menstrual period does not clear in 10 days, it may be a submucosal fibroid or an interstitial fibroid that is protruding into the endometrium, affecting the shape of the endometrium and making it unable to shed on time for a long time, or if the uterine cavity becomes large and the contraction of the uterus is poor, the menstrual period may be prolonged. In this case, the site of the fibroid should be identified. If it is under the mucosa and the fibroid is not very large, hysteroscopic electrosurgery can be performed and the menstruation can be restored to normal after the surgery. If the patient is older and has multiple fibroids, and the fibroids are large, a total hysterectomy can be performed to cure the problem completely.
