The aim: About 10% of socially active women of reproductive age suffer from endometriosis, is determined by the frequent occurrence of menstrual and reproductive functions disorders, and pelvic pain syndrome in patients. The difficulties of therapeutic treatment of chronic pain syndrome in external genital endometriosis (EGE) are associated with polymorphism of pain mechanisms, and delayed diagnosis and treatment. The aim of the study is to improve the effectiveness of the treatment of external genital endometriosis. Material and methods: We examined 60 female patients of reproductive age, 40 - with histologically verified diagnosis of external genital endometriosis and 20 healthy women. We used the following methods of examination: general clinical, instrumental, endoscopic, morphological, the Visual Analogue Scale (VAS) to quantify pain, the Beck Depression Scale and the SF-36 questionnaire. Results: Before the treatment of patients with EGE, VAS scale scores indicated pain in 100% of patients, the indicators of depression and level of anxiety go beyond the normative. The results of the pre-treatment questionnaire indicated lower quality of life scores on the scales of physical and mental health components. As a result of treatment there was significant decrease in the manifestations of pain, depression and anxiety, with women receiving complex therapy (hormone therapy got antidepressants and non-drug correction methods). Сonclusions: Chronic pelvic pain syndrome associated with EGE and accompanied by an unfavorable psychological state, depressive states, anxiety symptoms, and psychosomatic disorders. New approaches to the treatment of clinical manifestations of EGE are needed, taking into account patients' psycho-emotional status and the life quality analysis. We pathogenetically justified the use of drugs that affect the psychosomatic status of patients with EGE and showed that they could significantly improve the quality of life.
