Endometriosis often occurs in the area of the rectal fossa or vaginal rectal diaphragm. Its clinical symptoms often vary depending on the site of endometriosis. The main manifestations are pain in the lower abdomen, even traction between the vagina, the coccyx and the anorectum, with severe cramping pain and painful intercourse, and also amplitude pain to the upper abdomen or the hypochondrium. The pain refuses to be pressed, but if the disease is prolonged, it likes to be pressed. If the endometriosis occurs in the uterine body, the uterine body enlarges, and excessive menstrual flow is seen when the uterus contracts for menstruation, and the more menstrual flow, the more painful it is. In some patients, there is no history of dysmenorrhea, but endometriosis is only discovered during gynecological examination or surgery. There are many clinical manifestations of endometriosis, such as dysmenorrhea (mainly secondary to progressive dysmenorrhea), abnormal menstruation, infertility, painful intercourse, pelvic pain, hypothermia, and increased leucorrhea and menstrual discomfort. Due to the presence of estrogen and progesterone receptors in the ectopic endometrium, clinical signs and symptoms often show their inherent cyclical nature. Dysmenorrhea, infertility, and menstrual abnormalities are typical symptoms of endometriosis. A history of painful intercourse is often not easily obtained because of patient concealment. Gynecologic examination may reveal ectopic nodules or masses, and laparoscopy and ultrasound are helpful for diagnosis. During gynecologic examination, the posterior wall of the uterus, the uterosacral ligament, and the rectal fossa should be carefully examined, and the diagnosis can be made if 1-2 painful nodules the size of a pea are detected. Ovarian chocolate cysts that are not associated with lesions in the rectal fossa are very similar to adnexal inflammatory masses on internal examination, and a hysterosalpingogram is performed. If it shows bilateral patency of the fallopian tubes, inflammatory masses can be basically excluded. However, endometriosis can involve the fallopian tubes or complicate inflammation of the fallopian tubes in some cases. Therefore, when changes such as fluid accumulation, incompetence or even complete failure to visualize are seen, this disease is not completely excluded. Endometriosis is one of the common diseases in gynecology. In addition to progressive and severe dysmenorrhea, it is often combined with excessive menstruation and infertility, causing great pain to the patient. Although there is no name for endometriosis in the ancient Chinese medical text, its clinical symptoms belong to the categories of dysmenorrhea, menorrhagia and Y obstruction. According to clinical observation, the symptoms and signs of endometriosis vary according to the different ectopic locations and stages. The cause of this disease, according to modern medical science, is endometriosis, and its series of symptoms are mainly due to the proliferation, secretion and shedding of the ectopic endometrium under the cyclic action of female hormones, and the blood has no way out and accumulates in a certain area, stimulating the local tissues. The blood without a way out is called “blood that leaves the menstrual cycle” in Chinese medicine. It is also called “blood stasis”. After the formation of “blood stasis” as a pathological product, it becomes a pathogenic factor in turn. Therefore, “stasis” is the key to the symptoms and signs of endometriosis. The formation of blood stasis is mostly caused by liver and spleen stagnation in the organs, and condensation of cold, dampness and fire in the evil, and stagnation of blood stagnation makes it easy for other changes to occur. Therefore, according to the clinical manifestations of endometriosis, we can see that: qi stagnation, blood stasis, and cold evil attracts, and if it does not pass, it is painful, and it becomes dysmenorrhea; if the liver and spleen are not in control of the collection, or if fire and yang are hyperactive and stasis block the veins and ligaments, blood does not return to the menstrual cycle, which is leakage; if the spleen and kidney are deficient or stasis and dampness block the ligaments and ligaments, which is infertility; stasis accumulates and becomes lumps and nodules. Therefore, the diagnosis and treatment of endometriosis must focus on blood stasis and its complex pathological changes. It can be treated with a combination of Chinese and Western medicine, through oral Chinese medicine, Chinese medicine enema, Chinese medicine ionization, etc. If necessary, surgery is required.
