Endometriosis is generally seen only in women of childbearing age, and its incidence has increased significantly in recent years, making it one of the common gynecologic diseases. It refers to the presence of active endometrial tissue in parts of the body other than the mucosa covering the uterine cavity. It is associated with cyclic changes in the ovaries, and ectopic endometrial tissue can be absorbed after menopause or removal of the ovaries. Treatment of this condition requires a comprehensive consideration of the treatment modality in relation to the patient’s age, symptoms, location and extent of the lesion, and the presence or absence of fertility requirements. Young, fertile, mild patients should be treated with sex hormone therapy first, or conservative surgery for more severe lesions; young, non-fertile, severe patients can be treated with surgery to preserve ovarian function and hormone therapy; older, non-fertile patients with severe symptoms and lesions can be considered for radical surgery (which includes the uterus, both adnexa and the pelvis). All endometriotic lesions in the pelvis). In summary, unless radical surgery is performed or the patient is menopausal, other treatments have the potential to recur, so medication is usually given after conservative surgery in order to reduce the recurrence rate after surgery.
