Summary. The aim. Improving the results of treatment of patients with intestinal anastomotic leak by determining the role of undifferentiated connective tissue dysplasia in the development of these complications. Materials and methods The object of the study comprises 45 patients with anastomotic leak and with phenotypic signs of undifferentiated connective tissue dysplasia, who were treated in the Shalimov National Institute of Surgery and Transplantology during 2017-2020. Laboratory, histological, immunohistochemical studies and statistical analysis were performed. Results and discussion. With comprehensive study of tissue fragments small and large intestines revealed similar morphological characteristics in groups of phenotypic traits undifferentiated connective tissue dysplasia and with intestinal anastomotic leak. In immunohistochemical study of tissues with monoclonal antibodies to α-smooth muscle actin revealed uneven focal expression in smooth muscle cells and fibroblast; with monoclonal antibodies to Collagen IV there is a moderate positive expression in the basement membrane of blood vessels, in smooth muscle cells of the muscular layer of the vascular wall, in areas of connective tissue. Conclusions. Immunohistochemical examination of small and large intestinal tissues with monoclonal antibodies to Collagen IV and α-smooth muscle actin revealed signs of pathological connective tissue remodeling in the areas of anastomotic leak.
Summary. The aim. To analyze the frequency of polymorphic variants of matrix metalloproteinase-2 (C-1306→T) (MMP-2) and tissue matrix metalloproteinase-2 (G303→A) (TIMP-2) genes in patients with eventration. Materials and methods. The study included 11 patients with eventration and 44 patients with connective tissue pathology. Laboratory, genetic and statistical studies were performed. Results and discussion. All models of inheritance are analyzed and the best model with the lowest information criterion Aikaike, which turned out to be a recessive model, is determined. Conclusions. As a result of genetic and statistical analysis of polymorphism of MMP-2 (C-1306→T) and TIMP-2 (G303→A) genes, it was found that polymorphic variants of these genes are not reliably associated with the development of eventration.
Кафедра хірургії (зав.-проф. І.Ю. Полянський) Буковинського державного медичного університету, м. Чернівці ГОСТРИЙ ПЕРИТОНІТ НА СУЧАСНОМУ ЕТАПІ-ПРОБЛЕМИ, ЗДОБУТКИ І ПЕРСПЕКТИВИ Резюме. Узагальнено досвід лікування понад 1200 хворих на гострий перитоніт впродовж 20 років. Для хворих застосована розроблена лікувальна тактика, яка базується на проведених дослідженнях механізмів патогенезу гострого перитоніту. Основою вибору комплексу лікувальних заходів становила запропонована класифікація гострого перитоніту. Наведений комплексний підхід передбачає використання розроблених методів діагностики перитоніту, санації і дренування очеревинної порожнини, визначення життєздатності порожнистих органів травлення, способів накладання швів і профілактики їхньої неспроможності, методів післяопераційного лікування. Застосування такої тактики дозволило знизити летальність при поширених формах перитоніту до 8,67%.
Summary. Retro- and prospective trial was based on data about 30 patients, suffering entero-colocutaneous fistula, who were treated in the Shalimov National Institute of Surgery and Transplantology during 2016-2019. There was revealed, that the most informative phenotypical markers of undifferentiated dysplasia of the connective tissue (UDCT) in patients, with entero-colocutaneous fistula, are visceral (83,3%), vascular (70%), arrhythmic (70%) syndromes. There was founded, that direct correlation between the level of biochemical markers of the collagen biodegradation and the UDCT degree may be applied for prognostication of development and course of complications in patients, suffering entero-colocutaneous fistula. Severe degree of UDCT in the patients, entero-colocutaneous fistula, constitutes unfavorable prognostic sign and enhances the mortality by 62.5%. The presence of UDCT in the patients winh entero-colocutaneous fistula is an aggravating comorbid factor that is difficult to be treated and accompanied by high rates of lethality, which must be taken into account, choosing the adequate surgical tactics and complex pathogenetically substantiated treatment.
основі аналізу результатів операційних втручань та результатів хірургічного лікування 230 хворих з ПВГ у хірургічному відділенні ЧОКЛ впродовж 2009-2013 років виявлено значну перевагу алопластики сітчастими матеріалами. Правильний вибір способу операційного лікування потребує індивідуального підходу до кожного конкретного хворого, а належна передопераційна підготовка та післяопераційне лікування дозволяє звести до мінімуму післяопераційні ускладнення та зменшити частоту виникнення рецидивів.
