Fibroids that grow in the mucous layer of the uterus are called submucous fibroids and usually require surgery. Uterine fibroids are the most common benign gynecologic tumor and are most common in women between the ages of 30 and 50. Submucous fibroids are fibroids that grow abruptly into the uterine cavity. Since the surface of fibroids is covered with endometrium, it increases the area of endometrium and occupies the uterine cavity, which affects menstrual blood discharge, and thus can cause abnormal uterine contraction and dysmenorrhea, accompanied by heavy menstruation and cycle disorders. Excessive menstruation leads to secondary anemia, ineffective drug treatment, severe abdominal pain, and degeneration of leiomyoma requiring surgical treatment. Patients with submucosal fibroids who wish to preserve fertility can have the fibroid removed hysteroscopically, and submucosal fibroids protruding into the vagina can be removed vaginally. Patients without fertility requirements, patients with large fibroids secondary to severe anemia or patients with suspected malignant changes need to undergo hysterectomy. It is recommended that patients go to regular hospitals to receive systematic treatment in time.
