Symptomatic niches in the uterine scar after cesarean section: analysis of the causes of development and clinical manifestations
Objective. Identification of the most significant reasons for the development of symptomatic niches. Material and methods. In the course of the study, two groups were formed: the main and the control. The main group consisted of 2 subgroups: Ia subgroup — 58 patients with clinical manifestations of insolvent scar on the uterus after CC and the thickness of retained myometry 2 mm Ib — 48 patients with insolvent scar on the uterus and the thickness of retained myometry 2 mm, but without symptoms. In order to identify the causes of the development of an insolvent scar on the uterus, a control group was created — patients (n=32) with a scar on the uterus after a caesarean section. Results. The causes of the development of large symptomatic niches (an incompetent scar on the uterus) are: the course of pregnancy complicated by exacerbation of bronchopulmonary diseases (HR=2.53; 95% CI: 1.096—5.867) and genitourinary systems (HR=4.07; 95% CI: 1.024—16.214); anhydrous interval ≥12 hours (HR=10.2; 95% CI: 1.462—72.066); emergency CS (HR=2.19, 95% CI: 1.344—3.587); incision on the uterus repaired with a single-row suture (HR=2.6; 95% CI: 1.016—6.871); intrauterine interventions in the early postoperative period (HR=7.2; 95% CI: 1.020—51.486); adenomyosis (p<0.05), duration of labor for ≥6 hours (HR=2.7; 95% CI:1.206—6.395). Conclusion. Symptomatic scar niches on the uterus after a large cesarean section are a multifactorial disease. Symptoms of an untenable scar on the uterus can begin to bother patients as early as 6 months to 5 years after CS, averaging 2.3±0.4 years and have various clinical manifestations.

Causes of development, clinical picture of ectopic pregnancy in the “niche” of the uterine scar after cesarean section
Objective. To determine the risk factors for the development of ectopic pregnancy in the uterine scar “niche” (URN) after cesarean section (CS). Material and methods. Factor analysis of pregnancy in the uterine scar “niche” after CS in 43 patients (main group) was carried out within the framework of the study. The control group consisted of 37 patients with pregnancy in the uterine cavity (n=15) and patients (n=22) with a post-CS uterine scar without signs of anatomical failure. Results. A high risk of pregnancy formation in the uterine scar “niche” was found in 33-37 years old patients with an incompetent uterine scar, who had a history of CS performed 1 year ago or less, chronic endometritis, intrauterine surgeries within the first 1—2 years after CS, 2 CS and more with an interval between them of less than 3 years. Conclusion. Patients with operated uterus have a high probability of repeated abdominal delivery, which increases the area of the scar on the anterior wall of the uterus, contributing to implantation of the fetal egg in the scar projection. The very existence of a uterine scar is a risk factor for pregnancy development in the uterine scar, and against the background of scar failure, the risk of pregnancy development in the scar niche is significantly increased.

Pregnancy in the «niche» of the scar on the uterus after cesarean section: the volumes of surgical treatment
Objective. To choose the optimal method of surgical treatment in patients with pregnancy in the «niche» of the scar on the uterus after cesarean section (CS). Material and methods. A retrospective study included 43 patients with confirmed pregnancy in an insolvent uterine scar after CS. Results. When comparing the results of the study and surgical treatment of patients with pregnancy in the uterine scar after CS, three variants of the formation of an insolvent scar are presented. Depending on the degree of the myometrial defect in the projection of the scar on the uterus after CS, possible volumes of surgical treatment in ectopic pregnancy were determined: vacuum aspiration of the fetal egg under the control of ultrasound or hysteroscopy (13.9%); metroplasty with simultaneous termination of pregnancy by vacuum aspiration of the fetal egg (76.7%); extirpation of the uterus without appendages (9.3%). Conclusion. Metroplasty with simultaneous termination of pregnancy by vacuum aspiration of the fetal egg ensures complete elimination of the fetal egg and restoration of anatomical integrity, which avoids re-attachment of the fetal egg in the scar area at the next pregnancy.

Pelvic organ prolapse in young women
The article presents a review of the literature on the problem of pelvic organ prolapse in women of young (up to 40 years old) age. This group of patients has remained out of the gynecologists’ attention, as this disease in young women is considered to be not widespread enough, but epidemiological data show the opposite. Development of the system of prevention aimed at correction of the early stages of the disease, optimization of surgical methods of treatment, as well as the algorithm of medical care in more advanced clinical observations will help to significantly improve the results of treatment of young women suffering from genital prolapse.

Methods of prevention of vaginal intraepithelial neoplasia in HPV-positive patients under radical surgery
In the review of scientific literature the methods of prophylaxis of vaginal intraepithelial neoplasia in HPV-positive patients, including those who underwent hysterectomy for diseases of the uterine body and cervix, are highlighted. In most cases, vaginal intraepithelial neoplasia developed in the upper third of the vagina, and the middle and lower thirds were affected in less than 10% of cases. Intraepithelial vaginal neoplasia provoked by insufficient excision of the vaginal wall during hysterectomy was detected in 39.5% of patients. Despite radical volumes of operations in surgical treatment of diseases of the body and cervix (hysterectomy), vaginal cancer was observed especially often in HPV-positive patients. Vaginal resection in HPV-positive patients during hysterectomy may be a method of vaginal cancer prevention.

Effectiveness of the new peptide analgesic Tafalgin in the treatment of postoperative pain
Терапия послеоперационной боли остается одним из важных направлений работы врача — анестезиолога-реаниматолога. Более 80% хирургических пациентов нуждаются в интенсивном лечении боли после операции. ЦЕЛЬ ИССЛЕДОВАНИЯ Оценить возможности применения тафалгина в терапии послеоперационной боли. МАТЕРИАЛ И МЕТОДЫ В 7 российских исследовательских центрах (Москвы, Санкт-Петербурга, Смоленска, Пензы и Рязани) проведено простое слепое многоцентровое сравнительное рандомизированное исследование. Включены 250 пациентов с послеоперационной болью после планового хирургического вмешательства средней степени травматичности и оценки критериев включения и невключения. Обезболивание включало в себя внутривенное введение 1000 мг парацетамола после окончания операции всем пациентам, затем пациентам 1-й группы назначали препарат тафалгин в дозе 4 мг подкожно 3 раза в сутки; у пациентов 2-й группы схема терапии боли состояла из введения плацебо подкожно, а через 8 ч вводили декскетопрофен в дозе 50 мг внутримышечно 3 раза в сутки; пациенты 3-й группы получали тримеперидин в дозе 20 мг подкожно 3 раза в сутки. Парацетамол вводили каждые 8 ч по 1000 мг, при этом максимальная суточная доза достигала 3000 мг. В качестве первичной конечной точки выбрана оценка TOTPAR [0—6]. В качестве вторичных конечных точек приняты оценка интенсивности боли в покое и динамике, оценка врачом-исследователем эффективности терапии и оценка неблагоприятных явлений (НЯ) от применения тафалгина. РЕЗУЛЬТАТЫ Интенсивность боли в различных временных точках оценки в среднем была статистически значимо ниже у пациентов группы тафалгина, чем у пациентов группы плацебо (p<0,0001), что показало превосходство обезболивающего эффекта тафалгина над плацебо. При сравнении эффективности тафалгина и тримеперидина разница средних величин TOTPAR [0—6] составила –0,06 с нижней границей 95% ДИ, равной –2,39, что доказывает приблизительно одинаковую анальгетическую мощность изучаемых препаратов. Оценка врачом-исследователем эффективности обезболивающей терапии была значительно выше у пациентов групп тафалгина и тримеперидина по сравнению с пациентами группы плацебо. Частота зарегистрированных случаев НЯ в течение исследования составила 4,4% (11/250). При этом степень тяжести НЯ во всех группах была легкой, изменения схемы терапии боли по причине развития НЯ в ходе исследования не зафиксировано. ВЫВОДЫ Доказаны гипотезы о превосходстве терапии препаратом тафалгин над плацебо и о неменьшей эффективности препарата тафалгин по сравнению с полным агонистом опиоидных рецепторов тримеперидином у пациентов с послеоперационной болью. Полученные результаты оценки параметров безопасности свидетельствуют о благоприятном профиле безопасности препарата тафалгин.

Myomectomy during pregnancy and caesarean section
The article presents a review of the scientific literature about myomectomy during pregnancy and cesarean section. The indications for myomectomy during pregnancy and caesarean section have not been fully determined. A number of authors believe that myomectomy should be performed in the delayed period because of the high risk of intra- and postoperative complications. However, the situation has changed over the last 5 years, and many researchers believe that myomectomy during pregnancy and delivery is not only effective, but also economically feasible.

A method for surgical treatment of patients with medium and/or high rectocele
ЦЕЛЬ ИССЛЕДОВАНИЯ Создать надежный способ хирургической коррекции среднего и высокого ректоцеле, значительно снижающий число рецидивов или не сопровождающийся рецидивами заболевания. МАТЕРИАЛ И МЕТОДЫ Предложен хирургический способ пластики тазового дна, основанный на восстановлении целостности ректовагинальной фасции путем подшивания ее к крестцово-маточным связкам, усилении прочности ректовагинальной перегородки пучками мышц, поднимающих задний проход, что обеспечивает фиксацию и поддержку пролабирующих стенок влагалища и прямой кишки. С использованием этого метода прооперированы 25 пациенток со средним и высоким ректоцеле II—III стадии в возрасте от 34 до 48 лет. Срок наблюдения за оперированными пациентками составил от 2 мес до 2 лет. РЕЗУЛЬТАТЫ Во всех наблюдениях рецидивов пролапса тазовых органов не отмечено. Стояние задней стенки влагалища соответствовало физиологическим нормам. Отмечено улучшение эвакуаторной функции прямой кишки. ЗАКЛЮЧЕНИЕ Предложенная пластика задней стенки влагалища с реконструкцией ректовагинальной перегородки создает прочную мышечно-фасциальную структуру между передней стенкой прямой кишки и слизистой оболочкой задней стенки влагалища, является высокоэффективной, позволяет значительно улучшить качество жизни пациенток и может служить методом выбора в лечении больных с высоким и средним ректоцеле.
