Современный взгляд на проблему постхолецистэктомического синдрома (по материалам Экспертного совета, состоявшегося 4 мая 2019 г. в городе Алматы, Казахстан)
Gallstone disease is revealed in 10–20% of the population with a clear tendency to affect the younger population. In a clinically manifested course, cholecystectomy remains the treatment of choice. Symptoms and signs persist or even become more severe after gallbladder surgery in 10-15% of cases (“postcholecystectomy syndrome”). Postcholecystectomy syndrome includes heterogeneous disorders of liver, pancreas, duodenum, sphincter of Oddi, etc. that can be associated with errors or negative consequences of surgical intervention. Often, symptoms may persist because of previously unrecognized chronic diseases of neighboring organs. The spectrum of effective conservative measures is rather limited. The Advisory Board was held on May 4, 2019, in Almaty (Kazakhstan) to re-estimate the definitions and categories related to the issue of the postcholecystectomy syndrome and to develop the diagnostic and treatment algorithm for patients with the postcholecystectomy dysfunction of the sphincter of Oddi. The statements discussed by the interdisciplinary team of gastroenterologists and surgeons were addressed to general practitioners, therapists, gastroenterologists, and surgeons. The Advisory Board emphasized that organic and functional biliary diseases manifest mainly by biliary pain, main characteristics of which were defined in the Rome IV consensus based on the statistical analysis of a large pool of clinical data. For a more accurate bile duct system assessment and the exclusion of cholelithiasis, the examination algorithm was proposed, which included abdominal ultrasound investigation, endoscopic ultrasound investigation of the pancreatobiliary area, and magnetic resonance cholangiopancreatography. Diagnostic algorithm for differentiation of functional biliary disorders from organic gastrointestinal pathology was developed. Sphincter of Oddi dysfunction may be considered as a postcholecystectomy syndrome manifestation in 1.5-3% of cases. Apart from rational nutrition, conservative management of functional gastrointestinal diseases implies pharmacological therapy. The efficacy of non-steroidal anti-inflammatory drugs, prokinetics, nitrates, antispasmodics, calcium channel antagonists, botulinum toxin, and hymecromone was demonstrated in previous studies. Papillosphincterotomy is not effective in relieving biliary pain in cases of the sphincter of Oddi dysfunction. The proposed algorithm for the management of patients with the postcholecystectomy syndrome was presented.Желчнокаменная болезнь выявляется у 10–20% населения и имеет четкую тенденцию к «омоложению». При наличии клинических симптомов основным методом лечения остается холецистэктомия, после которой у 10–15% пациентов клинические проявления сохраняются либо усиливаются (для обозначения таких ситуаций применяют термин «постхолецистэктомический синдром»). Постхолецистэктомический синдром объединяет неоднородные расстройства, включая нарушения функции печени, поджелудочной железы, двенадцатиперстной кишки, сфинктера Одди пр., которые могут быть связаны с погрешностями или последствиями хирургических манипуляций. Зачастую причиной сохранения жалоб оказываются ранее нераспознанные хронические заболевания других органов. Арсенал эффективных средств медикаментозной и немедикаментозной коррекции относительно невелик. С целью стандартизировать определения и категории, касающиеся проблемы постхолецистэктомического синдрома, и разработать алгоритм обследования и лечения пациентов с постхолецистэктомической дисфункцией сфинктера Одди 4 мая 2019 г. в городе Алматы (Казахстан) состоялся совет экспертов – представителей междисциплинарной команды из гастроэнтерологов и хирургов. Целевая аудитория – врачи общей практики, терапевты, гастроэнтерологи, хирурги. Согласно решению Экспертного совета, основным клиническим проявлением органических и функциональных заболеваний желчных путей является билиарная боль, подробные характеристики которой были выделены в материалах IV Римского консенсуса на основании статистического анализа большого объема клинических данных. Для более точной оценки состояния протоковой системы и исключения желчнокаменной болезни в план обследования включают ультразвуковое исследование органов брюшной полости, эндоскопическое ультразвуковое исследование панкреато-билиарной зоны, магнитно-резонансную холангиопанкреатографию. Функциональные билиарные расстройства необходимо дифференцировать с органическими заболеваниями органов пищеварения; с этой целью рекомендован план обследования пациентов. Дисфункцию сфинктера Одди можно рассматривать как вариант постхолецистэктомического синдрома; на долю таких случаев приходится 1,5–3%. Консервативное ведение при функциональных заболеваниях органов пищеварения, помимо рационального питания, подразумевает лекарственную терапию. Показана эффективность нестероидных противовоспалительных препаратов, прокинетиков, нитратов, спазмолитиков, антагонистов кальциевых каналов, ботулотоксина и гимекромона. Папиллосфинктеротомия при дисфункции сфинктера Одди не обладает должной эффективностью в купировании билиарной боли. Разработан алгоритм ведения пациентов при появлении билиарной боли и другой симптоматики после холецистэктомии
Assessment of Efficacy and Optimization of Antiplatelet Therapy in Patients with Ischemic Heart Disease
The review article presents the problems of inadequate disaggregant response to deaggregant therapy. So far no reliable information about the frequency and causes of these complications. Cardiovascular diseases stably hold the leading position among the causes of death in the world. Today, as we know, 50% of all deaths in developed countries are caused by coronary heart disease (CHD).
It requires astronomical sums to maintain social health population both in terms of improving the quality of life and its extension. It is the great social significance of the problem and its economic side is the main engines of progress in coronary surgery

Combination of Total-Reflection X-Ray Fluorescence Method and Chemometric Techniques for Provenance Study of Archaeological Ceramics
The provenance study of archaeological materials is an important step in understanding the cultural and economic life of ancient human communities. One of the most popular approaches in provenance studies is to obtain the chemical composition of material and process it with chemometric methods. In this paper, we describe a combination of the total-reflection X-ray fluorescence (TXRF) method and chemometric techniques (PCA, k-means cluster analysis, and SVM) to study Neolithic ceramic samples from eastern Siberia (Baikal region). A database of ceramic samples was created and included 10 elements/indicators for classification by geographical origin and ornamentation type. This study shows that PCA cannot be used as the primary method for provenance purposes, but can show some patterns in the data. SVM and k-means cluster analysis classified most of the ceramic samples by archaeological site and type with high accuracy. The application of chemometric techniques also showed the similarity of some samples found at sites located close to each other. A database created and processed by SVM or k-means cluster analysis methods can be supplemented with new samples and automatically classified
