Проведен систематический обзор и метаанализ 15 исследований (всего 869 пациентов), опубликованных с 2020 г., соответствующих современным стандартам лечения. Критерии включения: рецензируемые оригинальные статьи на русском или английском языках, посвященные эндоскопической поэтапной некрсеквестрэктомии через транслюминально установленный металлический стент диаметром более 1 см у пациентов с подтвержденным инфицированным отграниченным панкреонекрозом. Использовалась модель случайных эффектов для метаанализа.</p></sec><sec><title>Результаты исследования</title><p>Результаты исследования. Средневзвешенный показатель клинического успеха эндоскопической поэтапной некрсеквестрэктомии составил 89,5 % (95%-ный доверительный интервал (95% ДИ): 87,5–92,1 %). При этом наблюдалась высокая вариабельность результатов между исследованиями (от 61 до 100 %) и значительная гетерогенность (I2= 89,2 %). Средняя частота осложнений составила 18,8 % (95% ДИ: 12,5–25,1 %). Наиболее частыми осложнениями были: миграция стента (5,2 %), кровотечение (3,9 %) и обтурация стента (2,1 %). Анализ выявил значительную вариабельность в критериях определения клинического успеха в разных исследованиях.</p></sec><sec><title>Выводы</title><p>Выводы. Эндоскопическая поэтапная некрсеквестрэктомия является высокоэффективным методом лечения инфицированного отграниченного панкреонекроза с приемлемым профилем безопасности. Однако отсутствие единых стандартизированных критериев клинического успеха и высокая гетерогенность данных затрудняют сравнительный анализ. Для улучшения качества доказательной базы необходима разработка унифицированных определений успеха и осложнений, а также проведение рандомизированных контролируемых исследований.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim: to evaluate the clinical success and complication rates of endoscopic step-up necrosectomy in patients with infected walled-off pancreatic necrosis, based on an analysis of contemporary scientific publications.</p></sec><sec><title>Material and methods</title><p>Material and methods. A systematic review and meta-analysis of 15 studies (total of 869 patients) published since 2020 and conforming to current treatment standards was conducted. The inclusion criteria were peer-reviewed original articles in Russian or English focusing on endoscopic step-up necrosectomy via a transluminally placed metal stent with a diameter greater than 1 cm in patients with confirmed infected walled-off pancreatic necrosis. A random-effects model was used for meta-analysis.</p></sec><sec><title>Results</title><p>Results. The weighted mean clinical success rate of endoscopic step-up necrosectomy was 89.5 % (95% confidence interval (CI): 87.5–92.1 %). Considerable variability in outcomes was observed between studies (range: 61 to100%), with significant heterogeneity (I2= 89.2 %). The mean complication rate was 18.8 % (95% CI: 12.5–25.1%).The most frequent complications were stent migration (5.2 %), bleeding (3.9 %), and stent obstruction (2.1 %). The analysis revealed significant variability in the criteria used to define clinical success across the studies.</p></sec><sec><title>Conclusions</title><p>Conclusions. Endoscopic step-up necrosectomy is a highly effective treatment for infected walled-off pancreatic necrosis with an acceptable safety profile. However, the lack of unified, standardized criteria for clinical success and the high heterogeneity of the data complicate comparative analysis. To improve the quality of evidence, it is necessary to develop standardized definitions of success and complications, as well as to conduct randomized controlled trials.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>панкреонекроз</kwd><kwd>инфицированный панкреонекроз</kwd><kwd>отграниченный некроз поджелудочной железы</kwd><kwd>эндоскопическая некрсеквестрэктомия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pancreatic necrosis</kwd><kwd>infected pancreatic necrosis</kwd><kwd>walled-off pancreatic necrosis</kwd><kwd>endoscopic necrosectomy</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">Baron T.H., DiMaio C.J., Wang A.Y., Morgan K.A.
