Providing a necessary background of classical and weak regeneration notions, we focus on less well-known and mainly new construction of artificial classical regeneration, as well as recent method of regenerative envelopes for modeling modern energy efficient multiserver systems and high-performance computing cluster.

This paper presents interdisciplinary consensus on the use of protocols of high-intensity magnetic stimulation for the treatment of pelvic floor muscles dysfunction with anal incontinence in Russia.AIM: to highlight the discussion and the decision-making on the basis of an interdisciplinary consensus on the use of a new algorithm of peripheral and transcranial magnetic stimulation in the treatment of pelvic floor muscles dysfunction with the clinic of anal incontinence.RESULTS: the adoption of this consensus can serve as a basis for further research of this problem and optimize the results of treatment of patients with pelvic floor muscle dysfunction with anal incontinence. The data may be interesting for a wide range of medical specialists: general practitioners, gastroenterologists, coloproctologists, surgeons, neurosurgeons, gynecologists, urologists — anyone who encounter with manifestations of this disorder in a routine practice and chooses diagnostic and treatment options.CONCLUSION: protocols for the treatment of anal incontinence using high-intensity magnetic stimulation aimed at improving the quality of treatment of patients with anal incontinence are based on the Russian experience of using the methods discussed and the analysis of the results obtained are validated.
Введение. В патогенезе расстройств дефекации у больных с ректоцеле могут участвовать как анатомические, так и функциональные нарушения. Однако до настоящего времени о возможности консервативной терапии, направленной на коррекцию функциональных расстройств дефекации, изучены недостаточно. Цель: изучение эффективности использования методов включающих БОС-терапию (терапия биологической обратной связью, biofeedback терапия) и тибиальной нейромодуляции в лечении больных с функциональными расстройствами дефекации на фоне пролапса тазовых органов. Методика. Материалом исследования служили результаты обследования пациенток в возрасте от 18 до 75 лет с наличием функционального расстройства дефекации (ФРД) в сочетании с ректоцеле без ранее проводившихся попыток хирургической коррекции. Проведены оценка общеклинических данных, опрос при помощи специализированного опросника выраженности расстройств эвакуаторной функции толстой кишки, рентгеновская дефектография, аноректальная манометрия высокого разрешения до и после комплекса консервативной реабилитации при помощи БОС-терапии и тибиальной нейромодуляции. Результаты. Конечному анализу были доступны данные 60 пациенток. Ректоцеле 1-й степени выявлено у 3 человек (5%), 2-й - у 37 (61,7%), 3-й степени - у 20 (33,3%) участниц исследования. Средний балл по симптомному опроснику составил 11,4±3,7. ФРД I типа выявлено у 41 (68,3%), II типа - у 6 (10%), III - у 10 (16,7%) и IV - у 3 (5%) участниц. После проведенной БОС-терапии признаки ФРД полностью устранены у 36,7% (22/60) женщин с ректоцеле. Неэффективной БОС-терапия оказалась у 11/41 (26,8 %) пациенток с I типом манометрического паттерна, 2/6 (33,3 %) со II типом и 4/10 (40,0 %) пациенток с III типом ФРД; (всего у 17/60 (28,3 %). У пациенток с IV типом паттерна неэффективные результаты лечения отсутствовали. Заключение. БОС-терапия и тибиальная нейромодуляция приводят к устранению симптомов в 36,7% случаев и положительной динамике у 35,0% больных. Методы могут быть рекомендованы к использованию в комплексной терапии эвакуаторных расстройств дефекации у больных с ректоцеле Aim. To assess the efficacy of conservative methods like biofeedback therapy (BFB) and tibial neuromodulation (TNM) for treatment of patients with functional FDD and rectocele. Methods. Information collected during examinations of female patients with FDD and rectocele and with no previous surgery served as source data. Before and after conservative treatment with BFB and TNM, symptoms were assessed, responses to a specialized questionnaire on the severity of rectal evacuatory function impairment were analyzed, and X-ray defecography and high-resolution anorectal manometry were performed. Data before and after treatment were compared with non-parametric statistics (Wilcoxon matched pairs test). Results. The data of 60 women (mean age 48.2±13.4 years) were analyzed. Rectocele grade 1 was detected in 3 (5%), grade 2 in 37 (61.7%), and grade 3 in 20 (33.3%) patients. Mean symptom score on the specialized questionnaire was 11.4±3.7. FDD type 1 manometric pattern was found in 41 (68.3%), type II in 6 (10%), type III in 10 (16.7%), and IV in 3 (5%) participants. Complete resolution of FDD after BFB and TNM therapy was found in 22/60 (36.7%) of women. BFB and TNM therapy was ineffective in 11/41 (26.8%) patients with FDD type I, in 2/6 (33.3%) with type II, and in 4/10 (40.0%) patients with type III FDD. This conservative treatment was effective in 100% patients with type IV pattern of FDD. Based on the results, we suggest further actions to improve the outcomes of conservative treatment. Conclusion. Conservative treatment with combined biofeedback therapy and tibial neuromodulation may help improve symptoms in 35% of patients and lead to complete resolution of functional component in 37% of patients with functional defecatory disorders and rectocele. This treatment was not effective in 28% of patients.
This manuscript summarizes consensus reached by the International Anorectal Physiology Working Group (IAPWG) for the performance, terminology used, and interpretation of anorectal function testing including anorectal manometry (focused on high-resolution manometry), the rectal sensory test, and the balloon expulsion test. Based on these measurements, a classification system for disorders of anorectal function is proposed. Aim to provide information about methods of diagnosis and new classification of functional anorectal disorders to a wide range of specialists general practitioners, therapists, gastroenterologists, coloproctologists all who face the manifestations of these diseases in everyday practice and determine the diagnostic and therapeutic algorithm. Current paper provides agreed statements of IAPWG Consensus and comments (in italics) of Russian experts on real-world practice, mainly on methodology of examination. These comments in no way intended to detract from the provisions agreed by the international group of experts. We hope that these comments will help to improve the quality of examination based on the systematization of local experience with the use of the methods discussed and the results obtained. Key recommendations: the International Anorectal Physiology Working Group protocol for the performance of anorectal function testing recommends a standardized sequence of maneuvers to test rectoanal reflexes, anal tone and contractility, rectoanal coordination, and rectal sensation. Major findings not seen in healthy controls defined by the classification are as follows: rectoanal areflexia, anal hypotension and hypocontractility, rectal hyposensitivity, and hypersensitivity. Minor and inconclusive findings that can be present in health and require additional information prior to diagnosis include anal hypertension and dyssynergia.
