In principle, non-surgical or surgical treatment for endometriosis is based on the patient’s age, symptoms, location and extent of lesions and fertility requirements. For patients with severe symptoms and lesions without fertility requirements, radical surgery can be performed to remove the uterus; for patients with less severe symptoms with fertility requirements, hormone therapy can be performed first; if the lesions are more severe, conservative surgery can be performed on the basis of preserving fertility functions. 1.Sex hormone therapy: inhibit ovulation, relieve symptoms and make the ectopic endometrium atrophy and degenerate, but sex hormone therapy is contraindicated for those with abnormal liver function. (1) Pseudopregnancy therapy: Long-term oral administration of a large amount of highly effective progestin, supplemented by a small amount of estrogen to prevent bleeding to cause amenorrhea similar to pregnancy, is called pseudopregnancy therapy. The method is to cause amenorrhea by taking 18 methylnortriptyline 0.3 mg and ethinylestradiol O.03 mg orally daily for 6 to 12 months. The dosage may be doubled when breakthrough bleeding occurs. It should be noted that the estrogen within the pill can stimulate the growth of fibroids, so use with caution if you have fibroids. (2) Pseudo-menopausal therapy: Danazol (with mild androgenic effects) is taken orally 400 mg daily for 6 months starting from the first day of menstruation. If symptoms do not resolve or amenorrhea does not occur, the dose may be increased to 600-800 mg daily. In case of occasional excessive liver function, it is advisable to stop the drug and give liver-protective treatment in time. (3) High-efficiency progestin therapy: 20-30 mg of progesterone orally daily for 6 months, or 250 mg of progesterone acetate intramuscularly every two weeks for 3 months and then change to 250 mg intramuscularly every month for 3-6 months. In case of breakthrough bleeding, ethylene estradiol 0.25 mg or O.5 mg daily may be added temporarily. Liver function should also be checked regularly during the drug administration. (4) Androgens: Methyltestosterone 5 mg sublingually daily for 3 to 6 months to relieve symptoms without suppressing ovulation. (5) Endometrium (18 monomethyltrienolone): It has strong anti-estrogen and progesterone effects. Each oral dose of 2.5 mg twice a week for 6 months, starting on the first day of menstruation. This drug is characterized by mild side effects and is easy to administer. (6) Gonadotropin-releasing agonist: It can cause a decrease in sex hormones secreted by the ovaries and temporary menopause. Long-term use of the drug may cause osteoporosis. It is suitable for menopausal women, especially those with combined uterine fibroids. (7) Mifepristone: It is a progestin inhibitor, which can make ectopic lesions atrophy. Long-term low-dose application is effective. It is administered as 10 mg daily, starting on the first day of menstruation, for 6 months. This drug has few adverse effects. This method is still in the trial stage. Since endometriosis is often combined with ovulatory dysfunction, resulting in infertility, for those who have fertility requirements, human menopausal gonadotropins or clomiphene can be used to promote ovulation during treatment to help conception. 2.Surgical treatment: Surgery is still one of the main means of treating endometriosis. It is suitable for those who have severe disease or severe pain and drug treatment is ineffective. (1) Surgery to preserve fertility: In only removing the endometriosis lesion, preserving the uterus and both or one side of the ovary. It is suitable for young people who have fertility requirements and drug treatment is ineffective. About 50% to 60% of them can get pregnant after surgery. However, the painful recurrence rate is high. (2) Surgery to preserve ovarian function: Removal of the ectopic lesion along with removal of the uterus, preserving at least part of the ovaries. It is suitable for those who have already had children. It can eradicate dysmenorrhea and the chance of recurrence of ectopic disease after surgery is rare. (3) Radical surgery: Removal of all endometriotic lesions in the bilateral vicinity and in the uterus and pelvis. It is suitable for menopausal women. (3) Radiation therapy: Suitable for those who are in serious condition, have difficulty in surgery or cannot tolerate surgery. Radiation therapy can be used to destroy the function of the ovaries and make the ectopic endometrium gradually degenerate.
