Congenital hypertrophic pyloric stenosis is one of the most common pathologies in the neonatal period and the first months of life, requiring urgent surgical treatment. For a long time, the standard treatment was open pyloromyotomy (Ramstedt stenosis), performed through a laparotomy. However, with the development of minimally invasive surgical techniques, laparoscopic pyloromyotomy (LP) has become widespread. Despite the widespread use of LP, questions remain regarding its comparative effectiveness and safety in modern pediatric surgery.</p> <p><bold>Materials and Methods.</bold> The authors conducted a systematic search of publications in PubMed, Science Direct, eLIBRARY, and Google Scholar databases in Russian and English for the period from 2010 to 2025. The risk of bias was assessed using the Cochrane RoB 2 and ROBINS-I tools. A random-effects model was used for quantitative data synthesis, assessing outcomes such as surgical duration, hospital stay, and the risk of intraoperative duodenal mucosal perforation.</p> <p><bold>Results</bold>. Data from 9 studies were included in the meta-analysis. No statistically significant differences were found between LP and OP for the primary outcomes: the pooled mean difference for operation duration was -1.62 minutes (95% CI: -17.39 to 14.15; p=0.765), for length of hospital stay it was -1.06 days (95% CI: -2.59 to 0.47; p=0.115), and the pooled relative risk for intraoperative mucosal perforation was 1.26 (95% CI: 0.45–3.57; p=0.587). At the same time, extremely high statistical heterogeneity was observed for continuous outcomes (I² &gt; 90%). The overall certainty of evidence, assessed using the GRADE methodology, was low.</p> <p><bold>Conclusions</bold>. The results of the systematic review and meta-analysis, based on quantitative synthesis, do not allow for a definitive conclusion regarding the superiority of LP or OP for key perioperative outcomes. However, a comprehensive analysis of qualitative data demonstrates that LP is associated with a comparable safety profile, as well as a number of potentially clinically significant benefits, such as reduced pain severity, early recovery and transition to enteral feeding, and improved cosmetic results.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> Врожденный гипертрофический пилорический стеноз является одной из наиболее распространенных патологий в периоде новорожденности и первых месяцев жизни, которая требует неотложного хирургического лечения. Длительное время стандартом лечения являлась открытая пилоромиотомия по Рамштедту, которая выполняется лапаротомным доступом. Однако, на фоне развития минимально инвазивных хирургических методов, лапароскопическая пилоромиотомия (ЛП) получила широкую распространенность. Несмотря на широкое применение ЛП, в современной детской хирургической практике остаются вопросы касательно ее сравнительной эффективности и безопасности.</p> <p><bold>Материалы и методы.</bold> Авторами проведен систематический поиск публикаций в базах данных PubMed, Science Direct, eLIBRARY и Google Scholar на русском и английском языках за период с 2010 - 2025 г.г. Риск систематической ошибки был оценен с использованием инструментов Cochrane RoB 2 и ROBINS-I. Для количественного синтеза данных использовалась модель случайных эффектов, оценивались такие исходы, как длительность операции, срок госпитализации и риск интраоперационной перфорации слизистой двенадцатиперстной кишки.</p> <p><bold>Результаты.</bold> В мета-анализ были включены данные из 9 исследований. Статистически значимых различий между ЛП и ОП по основным исходам выявлено не было: объединенная разность средних по длительности операции составила -1,62 мин (95% ДИ: от -17,39 до 14,15; p=0,765), по сроку госпитализации -1,06 дня (95% ДИ: от -2,59 до 0,47; p=0,115), объединенный относительный риск интраоперационной перфорации — 1,26 (95% ДИ: 0,45–3,57; p=0,587). При этом была выявлена крайне высокая статистическая гетерогенность по непрерывным исходам (I² &gt; 90%). Общий уровень доказательств, оцененный по методологии GRADE, был низким.</p> <p><bold>Заключение.</bold> Результаты проведенного систематического обзора и мета-анализа, основанные на количественном синтезе, не позволяют сделать однозначного вывода о преимуществах ЛП или ОП по основным периоперационным исходам. Однако совокупный анализ качественных данных демонстрирует, что ЛП ассоциирован с сопоставимым профилем безопасности, а также с рядом потенциальных клинически значимых преимуществ, таких как низкая выраженность болевого синдрома, раннее восстановление и переход энтеральное кормление и лучший косметический результат.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Hypertrophic Pyloric Stenosis</kwd><kwd>Laparoscopy</kwd><kwd>Comparative Effectiveness Research</kwd><kwd>Systematic Review</kwd><kwd>Meta-Analysis</kwd><kwd>Postoperative Complications</kwd><kwd>Length of Stay</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>врожденный гипертрофический пилорический стеноз</kwd><kwd>лапароскопическая пилоромиотомия</kwd><kwd>сравнительная эффективность</kwd><kwd>систематический обзор</kwd><kwd>мета-анализ</kwd><kwd>послеоперационные осложнения</kwd><kwd>длительность госпитализации</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">Dar OA, Ahmed N, Afzal T, Aziz M.
