Дано представление о возможном вкладе в их развитие микробиологического и генетического фактора. Также дана оценка возможного влияния матриксных металлопротеиназ и их тканевых ингибиторов. Одним из наиболее перспективных направлений в настоящее время считается механизм эпителиально-мезенхимального перехода, который способен объяснить формирование свищевой формы болезни Крона. Требуются дальнейшие исследования для выявления наиболее вероятной причины осложненного течения заболевания, что в перспективе позволит разработать подходы к патогенетической терапии у данной группы пациентов.</p></abstract><trans-abstract xml:lang="en"><p>The review evaluates pathogenesis of intestinal fistulas in Crohn’s disease (CD). An idea of the possible contribution of the microbiological and genetic factor is given. The possible effect of matrix metalloproteinases and their tissue inhibitors also assessed. One of the most promising areas which can explain development of intestinal fistulas in CD is epithelial-mesenchymal transition. Further research is required to identify the cause of the complicated CD, which in future will develop correct approaches to pathogenetic therapy.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>БК-ассоциированные свищи</kwd><kwd>эпителиально-мезенхимальный переход</kwd><kwd>пенетрирующая форма</kwd></kwd-group><kwd-group xml:lang="en"><kwd>CD-associated fistulas</kwd><kwd>epithelial-mesenchymal transition</kwd><kwd>penetrating form</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Podolsky DK.
