When it comes to myometriosis, it is a headache for many women. The main manifestation is severe menstrual pain, which may start without any cause or may appear after a particular uterine surgery, gradually worsening to the point of being unbearable and in some cases even requiring oral painkillers to control it. It is usually combined with infertility, excessive menstruation, painful intercourse and an enlarged uterus. The cause of myasthenia gravis is unclear, and it is possible that it is related to damage to the endometrium, as well as to a genetic component. Pathologically, the appearance of the endometrium can be seen within the myometrium, and since these endometrial glands can bleed during menstruation just like the endometrium in the uterine cavity, but the blood that comes out does not come out, it can cause severe pain. Dysmenorrhea and infertility due to myometriosis are often difficult to manage and are currently a tricky condition to treat. In mild cases, oral painkillers can be used to control dysmenorrhea, and patients with fertility requirements can actively try to conceive first. If the symptoms of dysmenorrhea are more pronounced, intervention is often required. A conservative treatment option is to try oral contraceptives first. Short-acting contraceptives can make the symptoms less severe in some patients with dysmenorrhea, but the inconvenience is that they need to be taken orally for a long time. Manuel is a new type of contraceptive ring that has emerged in recent years. It contains a progestin hormone that is slowly released in the body and can last up to 5 years, and can be effective in controlling dysmenorrhea and excessive menstruation if the patient does not have a large uterus. The disadvantage of Mannorrhea is that it is not suitable for patients with fertility requirements, and if the uterus is large, it is also not suitable to be placed, and some patients may suffer from shedding after the IUD is placed. Some patients may experience a significant decrease in menstrual flow after IUD release, and some patients are more likely to experience menstrual disorders during the first 6 months. If conservative treatment options are not effective, surgical treatment needs to be considered. Currently, surgical treatment is divided into conservative myeloablative lesion removal and radical hysterectomy. If you have fertility requirements, generally speaking, the hysterectomy is done, which can usually be done under minimally invasive laparoscopic surgery. If you have completed fertility and do not have fertility requirements, you can choose to have the lesion removed, but because myxomatous lesions are often diffuse, it is sometimes not easy to remove the lesion cleanly or there is a recurrence in the removal of the uterus; therefore, if it is acceptable, it is preferred to have the hysterectomy. If the dysmenorrhea is only caused by myometriosis, complete relief can usually be obtained, but in some patients with combined endometriosis, the dysmenorrhea may not be completely relieved. High-intensity focused ultrasound therapy (HEF) is a non-invasive treatment technique that has emerged in recent years. It is not an open-hearted means, but a technique that mediates ultrasound waves to the uterus through a concave and convex mirror-like focused ultrasound device to ablate the lesion, and its biggest advantage is fast recovery, no surgical scars and surgical adhesions to worry about. Many of our patients even had their menstrual cramps disappear completely after treatment. Since there is no problem with surgical scars, even if the pain reoccurs, it can be treated twice. For patients with fertility requirements, there is no conclusion as to what the final pregnancy outcome will be due to the small amount of study data.
