Endometriosis is a common gynecologic disease in women, which is a lesion caused by the growth of functional endometrial tissue outside the uterine cavity. The disease is most common in women of reproductive age and does not develop before puberty, and ectopic lesions can gradually shrink and degenerate after menopause. The presence of endometriosis can be determined clinically through a combination of symptoms and ancillary tests. 1. Judgment of endometriosis 1. Judgment according to clinical performance (1) lower abdominal pain and dysmenorrhea: secondary dysmenorrhea, progressive aggravation, mostly in the lower abdomen, lumbosacral and central pelvic area, often starting 1-2 days before menstruation, most acute on the first day of menstruation, gradually decreasing later and disappearing when menstruation is clean; (2) infertility: infertility rate of endometriosis patients is as high as 40%; (3) painful intercourse: painful intercourse before menstruation (4) Other symptoms: such as periodic frequent urination, painful urination, hematuria, abdominal pain, diarrhea or constipation, etc.; (5) Gynecological examination: one or more hard nodules, such as the size of green beans or soybeans, can be palpated in the rectal recess, uterosacral ligament or posterior wall of the cervix, with obvious tenderness. 2. Judgment according to auxiliary examination (1) Ultrasound examination: the uterus is enlarged with nodules and no envelope, and the ovaries are cystically enlarged bilaterally. The size and shape of cysts can be determined and masses not touched during gynecological examination can be found; (2) Laparoscopy: lesions in the uterus, fallopian tubes, ovaries, uterosacral ligament and pelvic peritoneum can be seen directly, and endometriosis can be staged and scored. (2) Treatment of endometriosis (1) Pseudopregnancy therapy: mainly using progesterone drugs, including oral progesterone, dydrogesterone, endometrium, etc.; (2) Pseudomenopausal therapy: commonly used gonadotropin-releasing hormone agonists, such as goserelin and leuprolide, are only injected subcutaneously once a month, which can strongly inhibit ovarian function, thus achieving the treatment purpose. (2) Surgical treatment (1) Surgery to preserve fertility: including unilateral adnexal resection, ovarian endometriosis foci resection, etc., for young women who have not yet had children; (2) Radical surgery: including total hysterectomy, bilateral adnexal resection and resection of the lesions seen, for women with severe lesions.
