Despite the active development and implementation of new surgical techniques for the treatment of Crohn’s disease, the incidence of postoperative complications remains high, i.e., up to 25%–30%. Until now, the influence of various factors on the outcomes of surgical interventions and the choice of differentiated techniques for the surgical treatment of children with Crohn’s disease remain highly debatable.</p> <p><italic><bold>AIMS:</bold> </italic>To study and identify possible risk factors for postoperative complications in children and adolescents with Crohn’s disease.</p> <p><bold><italic>MATERIALS AND METHODS:</italic> </bold>A retrospective nonrandomized clinical study included 164 pediatric patients (boys, <italic>n</italic> = 106, 65%) with complicated forms of Crohn’s disease. Early results of surgical interventions on the intestines were analyzed (up to 30 days after surgery). Postoperative complications were noted in 15% of cases after the initial surgery (20/133). In half of the cases (66/133) re-interventions on the intestines were performed at different times after the initial surgery, of which postoperative complications were detected in 14% of the cases (9/66). To determine risk factors in dichotomous variables, contingency tables were constructed with the calculation of the odds ratio (OR) and their 95% confidence interval (95% CI). Differences were recognized as statistically significant at <italic>p</italic> &lt; 0.05.</p> <p><bold><italic>RESULTS:</italic></bold> The following predictors of postoperative complications were identified: penetrating Crohn’s disease with strictures (OR 5,1; 95% CI 1,73–14,8; <italic>p </italic>= 0,0047), intestinal fistulas (OR 5; 95% CI 1,73–14,8; <italic>р </italic>= 0,0047), fibrosis in intestinal mucosal biopsy (OR 8,9; 95% CI 1,22–53; <italic>p </italic>= 0,0093), steroid therapy before surgery (OR 14,6; 95% CI 1,08–135; <italic>р </italic>= 0,0105), onset of CD in &lt;6 years of age (OR 10,8; 95% CI 1,16–137; <italic>р </italic>= 0,0177), combination of CD of any localization with lesions of the upper gastrointestinal tract (OR 13,8; 95% CI 1,01–143; <italic>р </italic>= 0,0247), severe hypoalbuminemia (OR 9,62; 95% CI 1,04–122; <italic>p </italic>= 0,0228) and no specific therapy for Crohn’s disease after surgery (OR 10,8; 95% CI 1,16–137; <italic>p</italic> = 0,0177).</p> <p><italic><bold>CONCLUSIONS:</bold> </italic>The development of surgical strategy in the preoperative period based on the identification of reliable predictors of adverse outcomes helps reduce the risk of postoperative complications. This improves the early outcomes of surgical treatment of children with complicated forms of Crohn’s disease.</p></abstract><trans-abstract xml:lang="ru"><p><bold><italic>Актуальность.</italic> </bold>Болезнь Крона — неизлечимое прогрессирующе заболевание желудочно-кишечного тракта, при котором до 90 % пациентов подвергается в течение жизни одной или нескольким операциям. Несмотря на активное развитие и внедрение новых хирургических методик для лечения пациентов с болезнью Крона, сохраняется высокая частота послеоперационных осложнений — до 25–30 %. До настоящего времени весьма дискутабельными остаются проблемы влияния различных факторов на результаты хирургических вмешательств у детей с болезнью Крона.</p> <p><bold><italic>Цель</italic> </bold>— изучение и выявление возможных факторов риска послеоперационных осложнений у детей и подростков с болезнью Крона.</p> <p><bold><italic>Материалы и методы. </italic></bold>В ретроспективное нерандомизированное клиническое исследование включено 164 ребенка, из них мальчиков было 106 (65 %), с осложненными формами болезни Крона. Проведен анализ ранних результатов оперативных вмешательств на кишечнике (сроком до 30 дней после операции). После первого хирургического вмешательства послеоперационные осложнения отмечены в 15 % наблюдений (у 20 из 133 человек). Повторные плановые вмешательства на кишечнике, выполненные в разные сроки после первой операции, проведены в половине случаев (66/133 — 50 %), послеоперационные осложнения выявлены в 9 (14 %) из 66 наблюдений. Для определения факторов риска в случае дихотомических переменных строили таблицы сопряженности с подсчетом отношения шансов (OШ) и их 95 % доверительного интервала (95 % ДИ), различия признавались статистически значимыми при <italic>p</italic> &lt; 0,05.</p> <p><bold><italic>Результаты.</italic> </bold>Выявлены следующие предикторы послеоперационных осложнений: пенетрирующий со стриктурами тип болезни Крона (ОШ 5,1; 95 % ДИ 1,73–14,8; <italic>р </italic>= 0,0047), кишечные свищи (ОШ 5; 95 % ДИ 1,73–14,8; <italic>р </italic>= 0,0047), фиброз в биоптате слизистой кишечника (ОШ 8,9; 95 % ДИ 1,22–53; <italic>р </italic>= 0,0093), проведение гормональной терапии до операции (ОШ 14,6; 95 % ДИ 1,08–135; <italic>р </italic>=0,0105), возраст дебюта болезни Крона меньше 6 лет (ОШ 10,8; 95 % ДИ 1,16–137; <italic>р </italic>= 0,0177), сочетание болезни Крона любой локализации с поражением верхних отделов желудочно-кишечного тракта (ОШ 13,8; 95 % ДИ 1,01–143; <italic>р </italic>= 0,0247), выраженная гипоальбуминемия (ОШ 9,62; 95 % ДИ 1,04–122; <italic>р </italic>= 0,0228), а также отсутствие специфической терапии после операции (ОШ 10,8; 95 % ДИ 1,16–137; <italic>р </italic>=0,0177).</p> <p><bold><italic>Заключение.</italic></bold> Выбор дифференцированной хирургической тактики в предоперационном периоде, основанный на выявлении имеющихся достоверных предикторов неблагоприятных исходов, может снизить риск послеоперационных осложнений, что в свою очередь позволит улучшить результаты хирургического лечения детей с осложненными формами болезни Крона.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Сrohn’s disease</kwd><kwd>surgery</kwd><kwd>postoperative complications</kwd><kwd>diagnostics</kwd><kwd>children</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>болезнь Крона</kwd><kwd>хирургическое лечение</kwd><kwd>послеоперационные осложнения</kwd><kwd>диагностика</kwd><kwd>дети</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Sykora J, Pomahacova R, Kreslova M, et al.
