Определить диагностическую информативность различных методов исследования для диагностики, дифференциальной диагностики, определения степени активности воспалительных заболеваний кишечника. Материалы и методы. Было обследовано 210 пациентов с язвенным колитом (ЯК) и болезнью Крона (БК). Всем пациентам было выполнено эндоскопическое исследование толстой кишки с применением функций виртуальной хромоскопии (NBI) и аутофлюоресценции (АФИ), эндосонографическое исследование (ЭУС), трансабдоминальное ультразвуковое исследование (УЗИ) и компьютерная томография (КТ). Были рассчитаны показатели диагностической и прогностической значимости методик. Результаты исследования. Полученные во время проведения исследования результаты показали, что для выявления ЯК и БК наиболее информативными являются методы NBI (ЯК: Se= 81%, Sp= 71%, БК: Se = 75%, Sp= 70%) и ЭУС (ЯК: Se = 90%, Sp= 81%, БК: Se = 74%, Sp= 80%). Для дифференциальной диагностики ЯК и БК, также диагностически и прогностически значимыми, являлись вышеуказанные методики (NBI: Se = 81%, Sp= 73%, ЭУС: Se = 81%, Sp= 74%). Уточнение степени выраженности воспаления ЯК посредством различных методов обследования показало информативность трех методик: NBI (Se = 79%, Sp= 71%), ЭУС (Se = 86%, Sp= 67%) и КТ (Se = 78%, Sp= 61%). Аналогичные данные были получены и при идентификации фазы воспаления БК NBI (Se = 75%, Sp= 71%), ЭУС (Se = 71%, Sp= 64%) и КТ (Se = 74%, Sp= 66%). Выявление неоплазии показало низкие цифры диагностической значимости всех лучевых методов, при этом и NBI, и АФИ являлись информативными (Se = 100%, Sp= 95%; Se = 87%, Sp= 80% соответственно). Заключение. Суммируя полученные данные, были разработаны алгоритмы диагностики ВЗК на различных этапах обследования пациентов.</p></abstract><trans-abstract xml:lang="en"><p>Aim. To determine the diagnostic information content of various research methods for diagnosis, differential diagnosis, and determination of the degree of activity of inflammatory bowel diseases. Materials and methods. 210 patients with ulcerative colitis (UC) and Crohn’s disease (CD) were examined. All patients underwent endoscopic colon examination using virtual chromoscopy (NBI) and autofluorescence (AFI), endosonographic examination (EUS), transabdominal ultrasound and computed tomography (CT) of the colon. The indicators of diagnostic and prognostic significance of the methods were calculated. Results. The results obtained during the study showed that the most informative methods for detecting UC and CD are NBI (UC: Se= 81%, Sp= 71%, BC: Se = 75%, Sp= 70%) and EUS (UC: Se = 90%, Sp= 81%, BC: Se = 74%, Sp= 80%). The above methods were also diagnostically and prognostically significant for the differential diagnosis of UC and CD (NBI: Se = 81%, Sp= 73%, EUS: Se = 81%, Sp= 74%). Clarifying the severity of UC inflammation through various examination methods showed the informative value of three methods: NBI (Se = 79%, Sp= 71%), EUS (Se = 86%, Sp= 67%) and CT (Se = 78%, Sp= 61%). Similar data were obtained when identifying the inflammatory phase of CD NBI (Se = 75%, Sp= 71%), EUS (Se = 71%, Sp= 64%) and CT (Se = 74%, Sp= 66%). The detection of neoplasia showed low figures of diagnostic significance of all radiation methods, while both NBI and API were informative (Se = 100%, Sp= 95%; Se = 87%, Sp= 80%, respectively). Conclusion. Summarizing the data obtained, algorithms for the diagnosis of IBD were developed at various stages of the examination of patients.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>воспалительные заболевания кишечника</kwd><kwd>язвенный колит</kwd><kwd>болезнь Крона</kwd><kwd>виртуальная хромоскопия</kwd><kwd>аутофлюоресценция</kwd><kwd>эндосонография толстой кишки</kwd><kwd>трансабдоминальной ультразвуковое исследования</kwd><kwd>компьютерная томография</kwd></kwd-group><kwd-group xml:lang="en"><kwd>inflammatory bowel diseases</kwd><kwd>ulcerative colitis</kwd><kwd>Crohn’s disease</kwd><kwd>virtual chromoscopy</kwd><kwd>autofluorescence</kwd><kwd>colon endosonography</kwd><kwd>transabdominal ultrasound</kwd><kwd>computed tomography</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">Ulcerative colitis.
