However, maintained heterogeneity of approaches and diagnostic errors still affect outcomes.</p> <p>A search and analytical summary of domestic and foreign publications was performed, with the priority given to clinical recommendations, systematic reviews/meta-analyses, multicenter studies, and large clinical series. The search was conducted in the eLibrary, PubMed, and Scopus databases for the period 01.01.2020–31.12.2025 using Russian and English keywords related to intussusception in children (diagnosis, pathological leading point, disinvagination, surgical tactics); the manual review of bibliographies on key publications was done as well. The analytical part of the review includes 27 sources, on the basis of which conclusions and tables were formed.</p> <p>The clinical and instrumental signs of a probable pathological leading point and the ultrasound criteria for intestinal wall viability were summarized. It was shown that pneumatic/hydrostatic disinvagination under ultrasound or X-ray control is possible at an early stage; however, if it is ineffective, there are doubts about adequate perfusion, or there is a high probability of a pathological leading point, it is advisable to switch to diagnostic and therapeutic laparoscopy with mandatory removal of the pathological leading point, if present. The authors also outline situations requiring resection with the restoration of intestinal tube continuity. Organizational conditions reducing the proportion of emergency resections and complications (early availability of ultrasound, standardized routes, interdisciplinary interaction) as well as the role of machine learning algorithms and clinical predictive models as auxiliary decision support tools are highlighted as well. An age-oriented, practice-oriented management algorithm for children older than one year is presented: from recognizing the signs of pathological leading point and justifying the refusal of further attempts at disinvagination to the structure of laparoscopic intervention. Application of the presented scheme is intended to reduce the frequency of relapses and complications as well as to improve immediate and long-term treatment outcomes.</p></abstract><trans-abstract xml:lang="ru"><p>У детей старше одного года жизни кишечная инвагинация чаще связана с патологической ведущей точкой, что снижает частоту успешности исключительно консервативных вмешательств и повышает значение своевременного оперативного лечения, при этом сохраняются разнородность подходов и диагностические ошибки, влияющие на исходы.</p> <p>В статье представлена поисково-аналитическая сводка отечественных и зарубежных публикаций с приоритетом клинических рекомендаций, систематических обзоров/метаанализов, многоцентровых исследований и крупных клинических серий. Поиск проведён в базах данных eLibrary, PubMed и Scopus за период 01.01.2020–31.12.2025 с использованием русско- и англоязычных ключевых слов по кишечной инвагинации у детей (диагностика, патологическая ведущая точка, дезинвагинация, хирургическая тактика), а также ручного просмотра списков литературы ключевых публикаций. В аналитическую часть обзора включено 27 источников, на основании которых сформированы выводы и таблицы.</p> <p>Обобщены клинико-инструментальные признаки вероятной патологической ведущей точки и ультразвуковые критерии жизнеспособности кишечной стенки. Показано, что пневматическая/гидростатическая дезинвагинация под ультразвуковым или рентгенологическим контролем возможна на раннем этапе, однако при неэффективности, сомнениях в адекватной перфузии целесообразен переход к диагностической и лечебной лапароскопии с обязательным устранением патологической ведущей точки при её наличии. Описаны ситуации, требующие резекции с восстановлением непрерывности кишечной трубки. Выделены организационные условия, уменьшающие долю экстренных резекций и осложнений (ранняя доступность ультразвукового звена, стандартизированные маршруты, междисциплинарное взаимодействие), а также роль алгоритмов машинного обучения и клинических предиктивных моделей как вспомогательных инструментов поддержки решений. Представлена возраст-ориентированная, практико-направленная схема ведения детей старше одного года: от распознавания признаков патологической ведущей точки и обоснования отказа от дальнейших попыток дезинвагинации до технических аспектов лапароскопического вмешательства. Применение такой схемы призвано снизить частоту рецидивов и осложнений и улучшить непосредственные и отдалённые результаты лечения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>intussusception</kwd><kwd>surgical procedures</kwd><kwd>pathological lead point</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>кишечная инвагинация</kwd><kwd>хирургическая процедура</kwd><kwd>патологическая ведущая точка</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Clinical Guidelines of the Russian Federation 2024 (Russia).
