Endometriosis is a common gynecological disease in women, often causing dysmenorrhea, painful intercourse, and even infertility, so for mild endometriosis patients, no special treatment can be given. However, for women with dysmenorrhea or painful intercourse, they can be treated with drugs, such as oral short-acting contraceptives, or gonadotropin-releasing hormone agonists, which can shrink the endometrium to achieve treatment; however, if drug treatment is not effective, and for younger women with fertility requirements, the ectopic endometrial lesions can be surgically removed to preserve the uterus and ovaries, but they are still prone to recurrence after surgery; and for older women and those without fertility requirements, the uterus and ectopic endometrium can be removed and part of the ovaries can be preserved. For older women and women without fertility requirements, the uterus and ectopic endometrium can be removed and some of the ovaries can be preserved, which can reduce recurrence; however, for women who are fast menopausal and have severe and intolerable menstrual pain, the uterus and bilateral adnexa can be directly removed for the purpose of radical treatment. In conclusion, the treatment of endometriosis is mainly by follow-up, medication, partial surgical excision or radical surgical excision.
