Endometriotic ovarian cysts are invaginated cysts of the ovarian cortex that contain endometrial glands and stroma. The endometrial tissue that is implanted in this spot is sensitive to hormones and undergoes the same cyclical changes as the endometrial tissue inside the uterus during the menstrual cycle. Due to these changes, cysts cause a wide range of symptoms, however in adolescence they are somewhat different and often not identified in time. In addition to typical symptoms such as dysmenorrhea and pelvic pain throughout the cycle, there are also nonspecific ailments, and in most cases the disease is asymptomatic at that age. Endometriotic ovarian cysts are active formations that, by releasing metalloproteinases and other substances, cause damage to the ovarian cortex and the follicles themselves, and ultimately lead to fertility problems. Transvaginal ultrasound is used in the diagnosis of endometriotic cysts, but the gold standard diagnosis is laparoscopy with pathohistological confirmation of the disease. Conservative treatment includes pharmacological therapy and surgery and their combination. Since radical therapy is avoided in adolescent patients, after a detailed examination, the patient starts with symptomatic drug therapy. If there is no improvement, the patient moves on to laparoscopy and surgery with maximum ovarian sparing. Alternative methods of treating endometriotic ovarian cysts have not yet been sufficiently explored, but recently more and more younger patients are turning to them for minimal side effects and to avoid radical therapy. Acupuncture is used primarily to relieve symptoms, chiefly pelvic pain. Phytotherapy has a wide range of effects, so some plants and their products act symptomatically, while others act to reduce the endometriotic cysts themselves. The combination of micro-waves and Chinese herbal enemas has proven to be very effective because the medicinal substances penetrate the lesions much better and bypass digestive enzymes and the liver. There are many less researched alternative methods and they are chosen as adjuvant therapy to conservative therapy depending on the wishes of patients.
