Выявить информативность различных признаков при применении методов виртуальной хромоскопии (ВХ) и аутофлюоресценции (АФ) во время проведения эндоскопического исследования для определения степени выраженности воспалительного процесса при язвенном колите (ЯК) и болезни Крона (БК). Материалы и методы. Был обследован 151 пациент с ВЗК (51- с БК, 100 - с ЯК). Всем пациентам было выполнено эндоскопическое исследование толстой кишки с использованием функций виртуальной хромоскопии и аутофлюоресценции и взятием биопсийного материала для гистологического исследования. Результаты исследования. При минимальной степени ЯК было выявлено отсутствие венул при ВХ (p&lt;0,05), а также зеленое окрашивание с очагами фиолетового цвета при АФ (p&lt;0,05). Умеренная степень характеризовалась визуализацией венул подслизистого слоя (p&lt;0,001) и фиолетовым окрашиванием слизистой оболочки (СО) с очагами зеленого цвета (p&lt;0,001). Выраженная степень воспаления СО при АФ была окрашена диффузно в фиолетовый цвет (p&lt;0,001), и отсутствием двух видов сосудистого рисунка при проведении ВХ (р&lt;0,001). При БК фаза инфильтрации характеризовалась визуализацией двух типов зеленого окрашивания в режиме АФ в сопоставимых количествах, что было статистически значимо чаще других цветов (р=0,033 и р=0,006). В фазе язв при ВХ преимущественно мы определяли визуализацию либо капилляров, либо венул в одинаковых количествах (р&lt;0,001). В фазе рубцов частота встречаемости различных видов окрашивания при АФ была сопоставима с таковой в фазе ремиссии и с группой контроля, при ВХ- оба вида сосудистого рисунка выявлялись с достоверно высокой частотой (р=0,001). Заключение. Исходя из результатов исследования, ВХ и АФ являются дополнительными методами в диагностике степени активности ВЗК и могут применяться в сложных случаях для уточнения выраженности воспаления у больных ЯК и БК.</p></abstract><trans-abstract xml:lang="en"><p>Aim. To identify the informative value of various signs when using virtual chromoscopy (VC) and autofluorescence (AFI) methods during an endoscopic examination to determine the severity of the inflammatory process in ulcerative colitis (UC) and Crohn’s disease (CD). Materials and methods. 151 patients with IBD were examined (51 with CD, 100 with UC). All patients underwent endoscopic colon examination using virtual chromoscopy and autofluorescence functions and taking biopsy material for histological examination. Results. With a minimum degree of UC, the absence of venules was revealed at VC (p&lt;0.05), as well as green staining with foci of purple color at AFI (p&lt;0.05). A moderate degree was characterized by visualization of the venules of the submucosal layer (p&lt;0.001) and purple staining of the mucous membrane (MM) with foci of green color (p&lt;0.001). The pronounced degree of inflammation of MM in AFI was diffusely colored purple (p&lt;0.001), and the absence of two types of vascular pattern during VC (p&lt;0.001). In CD, the infiltration phase was characterized by visualization of two types of green staining in AFI mode in comparable amounts, which was statistically significantly more common than other colors (p=0.033 and p=0.006). In the phase of ulcers with VC, we mainly determined the visualization of either capillaries or venules in the same amounts (p&lt;0.001). In the scar phase, the frequency of occurrence of various types of staining in AFI was comparable to that in the remission phase and with the control group, in VC - both types of vascular pattern were detected with a significantly high frequency (p=0.001). Conclusion. Based on the results of the study, VC and AFI are additional methods in diagnostics of the degree of IBD activity and can be used in difficult cases to clarify the severity of inflammation in patients with UC and CD.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>воспалительные заболевания кишечника</kwd><kwd>степень активности воспаления</kwd><kwd>аутофлюоресценция</kwd><kwd>виртуальная хромоскопия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>inflammatory bowel diseases</kwd><kwd>degree of inflammation activity</kwd><kwd>autofluorescence</kwd><kwd>virtual chromoscopy</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">Kumagai Y., Toi M., Inoue H.
