Uterine myoma is one of the most common gynecological tumor diseases. Myoma of muscle wall is often multiple, accounting for about 60-70%, and the number is uncertain. There are often one or several large and sometimes many small tumor nodules, which are distributed all over the uterine wall, showing irregular mass fusion, forming more uterine fibroids. Others involve the cervix or develop into the fornix, which is easily confused with primary cervical myoma. Intramural leiomyoma, due to good blood circulation, generally has less degeneration, which can seriously deform the uterine body and affect uterine contraction. Due to the increase of uterine volume and endometrial area, it often causes menorrhagia, frequent menstruation and prolonged menstruation. Intramural fibroids often enlarge uterus, bend and deform uterine cavity, proliferate endometrium or form endometrial polyps. In the process of growth and development, fibroids tend to develop in the direction of less resistance. When it protrudes into the uterine cavity, its surface is only covered with a layer of endometrium, which is called "submucous hysteromyoma", and even there is only one pedicle connected with the uterus. Submucosal myoma accounts for about 10%, which becomes a foreign body in the uterine cavity, causing uterine contraction, being pushed down, and the tumor pedicle gradually elongating. When it reaches a certain level, the myoma can pass through the cervical canal, hang down in the vagina or even protrude out of the vaginal orifice, and at the same time, the uterine wall attached to the pedicle is pulled and depressed inward. When the depression increases, different degrees of uterine inversion can be formed. This kind of tumor has poor blood supply and often extends into the vagina, causing necrosis and bleeding. Growing submucosal fibroids can distort the uterine cavity. If the myoma protrudes to the surface of the uterine body and is covered by a layer of peritoneum, it is called "subserous hysteromyoma". If it continues to develop in the direction of abdominal cavity, it can finally be connected with the uterus through only one pedicle, becoming a pedicled subserous uterine myoma. The tumor pedicle contains about 20% blood vessels, which is also the only blood circulation. If the tumor pedicle is twisted, it can make the tumor pedicle necrosis and fall off, and the myoma will leave the abdominal cavity and attach to the omentum, mesentery and other adjacent organs and tissues to obtain blood nutrition, which will become "parasitic myoma" or "free myoma", which can make the omentum partially twisted or blocked, resulting in abdominal symptoms such as leakage and ascites. Subserous or small intramural fibroids often have no obvious changes in the shape of the uterus. Myoma occurs when the uterine side wall extends between the peritoneum of broad ligament, which is called "broad ligament myoma" and belongs to subserous type. But there is also a kind of broad ligament myoma, which grows from the smooth muscle fibers beside the uterus in the broad ligament and has nothing to do with the uterine wall. Myoma of broad ligament often changes the position and shape of pelvic organs and blood vessels during its growth and development, especially the displacement of ureter. This brings difficulties to surgical treatment. The development of cervical myoma is the same as that of uterine body. However, due to the characteristics of its anatomical location, when the development of fibroids increases to a certain extent, it is easy to produce compression symptoms of adjacent organs, which often causes childbirth obstacles and increases the difficulty of surgery. More than 90% of uterine leiomyomas grow in the uterine body, and most of them are located in the posterior lip. In the body, they are longer than the bottom of the uterus, followed by the posterior wall. As far as the types of leiomyomas are concerned, intramural leiomyomas are the most, subserous leiomyomas are the second, and submucosal leiomyomas are rare. Multiple leiomyomas usually change the shape of the uterus. In larger cases of uterine leiomyoma, the ovary often appears edema, congestion or cystic degeneration. Some cases are accompanied by anovulatory menstrual cycles.

Over the years, I have accumulated extremely rich theoretical knowledge and clinical experience in obstetrics and gynecology and related disciplines. Familiar with the diagnosis and treatment technology of common and frequently-occurring diseases in obstetrics and gynecology, with solid theoretical foundation and clinical experience, able to handle difficult diseases, complications and complications in obstetrics and gynecology with ease. Especially in the emergency rescue of pregnancy-induced hypertension, postpartum uterine atony bleeding, fetal distress, amniotic fluid embolism, DIC and other critical diseases, as well as gynecological tumors, gynecological medical plastic surgery, infertility and other serious treatments. Successfully cured tens of thousands of critically ill gynecological patients, deeply appreciated by patients. Personal motto: people-oriented, do good things and do practical things for patients!
