Endometrial polyps are formed by localized hyperplasia of the endometrium and can occur at any age after puberty. Single, small polyps are usually asymptomatic, while large or multiple polyps can cause symptoms such as heavy menstrual flow, irregular vaginal bleeding, bloody discharge, and infertility. For small and asymptomatic endometrial polyps, they can be left untreated for the time being, and some of them can fall off on their own when the ultrasound is reviewed after menstruation; however, for patients with multiple polyps, large size, obvious symptoms or the possibility of malignant transformation cannot be ruled out, surgery is recommended, and the most common surgical procedure is hysteroscopic polyp removal. For those who have fertility requirements, endometrial polyps found before pregnancy should also be surgically removed, and the cut polyps should be sent for pathological examination, paying attention to the possibility of recurrence of endometrial polyps; for those who are older, have frequent recurrence of polyps or whose pathology suggests the possibility of malignant polyps, total hysterectomy can be performed. In short, according to the size of the endometrial polyps, symptoms, whether there is a tendency of malignant change and other comprehensive analysis, to determine the need for surgery, indeed, some small polyps can fall off on their own.
