Adenomyosis (add–en–o–my–OH–sis) may be a condition of the feminine genital system. It causes the uterus to thicken and enlarge. Endometrial tissue lines the within of the uterine wall (endometrium). Adenomyosis occurs when this tissue grows into the myometrium, the outer muscular walls of the uterus. The explanation for adenomyosis is unknown, although it's been related to any kind of uterine trauma which will break the barrier between the endometrium and myometrium, referred to as the junctional zone, like a cesarean delivery, surgical pregnancy termination, and any pregnancy. It are often linked with endometriosis, but studies looking into similarities and differences between these two conditions have conflicting results. The pathogenesis of adenomyosis still remains unclear, but the functioning of the inner myometrium, also called the junction zone is believed to play a serious role within the development of adenomyosis. It's also a matter of dialogue whether the link between reproductive disorders and major obstetrical disorders also lies here. Parity, age, and former uterine abrasion increase the danger of adenomyosis. Hormonal factors like local hyperestrogenism and elevated levels of s–prolactin also as autoimmune factors have also been identified as possible risk factors. As both the myometrium and stroma in an adenomyosis affected uterus show significant differences from those of a non–affected uterus, a posh origin that has multifactorial changes on both genetic and biochemical levels is probably going. The diagnosis of adenomyosis is thru a pathologist microscopically examining small tissue samples of the uterus. These tissue samples can come from a uterine biopsy or directly following a hysterectomy. Uterine biopsies are often obtained by either a laparoscopic procedure through the abdomen or hysteroscopy through the vagina and cervix. The diagnosis is established when the pathologist finds invading clusters of endometrial tissue within the myometrium.
The tissue injury and repair (TIAR) theory is now widely accepted and suggests that uterine hyperperistalsis (i.e., increased peristalsis), during early periods of reproductive life will induce micro–injury at the endometrial–myometrial interface region.That again results in elevation of local estrogen so as to heal the damage. At an equivalent time, estrogen treatment will increase uterine peristalsis again, resulting in a vicious circle and a sequence of biological alterations essential for the event of adenomyosis. Iatrogenic injury of the junctional zone or physiological damages thanks to placental implantation presumably leads to an equivalent pathological cascade. This also explains that adenomyosis often gets more severe after each pregnancy and childbirth, while endometriosis will ameliorate.
Misplaced endometrial tissue proliferation within the myometrium causes symptoms through different mechanisms. Uterine menstrual contractions are caused by prostaglandin, which is produced by normal endometrial tissue. Dysmenorrhea is that the main characteristic for this disease which are the result for top prostaglandin levels. Endometrial proliferation is additionally led by estrogen; some treatments attempt to reduce its levels so as to decrease symptoms. Adenomyosis patients present with heavy menstrual bleeding thanks to the rise of endometrial tissue, greater degree of vascularization, atypical uterine contractions and increased levels of prostaglandins, estrogen and eicosanoids. Several diagnostic criterion are often used, but typically they require either the endometrial tissue to possess invaded greater than 2% of the myometrium, or a minimum invasion depth between 2.5 to 8mm.
Adenomyosis can vary widely within the extent and site of its invasion within the uterus. As a result, there are not any established pathognomonic features to permit for a definitive diagnosis of adenomyosis through non–invasive imaging. Nevertheless, noninvasive imaging techniques like transvaginal ultrasonography (TVUS) and resonance imaging (MRI) can both be wont to strongly suggest the diagnosis of adenomyosis, guide treatment options, and monitor response to treatment. Indeed, TVUS and MRI are the sole two practical means available to determine a pre–surgical diagnosis.
