The gastric outlet atresia may be either isolated or combined with other abnormalities.</p><p><bold>Material and methods.</bold> There are few publications on the surgical treatment of pyloric atresia with extraluminal and intraluminal endoscopic interventions; however, at present information about it is not enough to assess their effectiveness and safety in young children. In literature, one can also find only few detailed reviews on clinical observations of pyloric atresia; most of which describe anatomical type I. Membranectomy and pyloroplasty are used for surgical treatment of pyloric atresia of type I. Surgery for pyloric atresias of types II and III which includes the resection in atresia zone and the formation of anastomosis between the stomach and duodenum causes complications due to the duodeno-gastric reflux in postoperative period. To prevent these complications, there is a surgical technique which was first described by A. Dessanti, et al. and later was modified and detailed by S. Yokoyama. This article is a literature overview on the topic and authors’ own experience in treating pyloric atresia of type II in 2 patients and of type I in one 1 patient.</p><p><bold>Conclusion.</bold> The choice of surgical approach depends on the anatomical type of pyloric atresia. Currently, there is no any unified approach to the surgical treatment of atresia of types II and III. Membranectomy and gastroduodenoanastomosis seem to be the most appropriate surgical techniques to correct this abnormality what has been confirmed by our preliminary findings.  </p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> Врождённая пилорическая атрезия – порок развития выходного отдела желудка, составляющий не более 1% всех атрезий желудочно-кишечного тракта у детей. Атрезия привратника может встречаться как изолированно, так и в сочетании с другими аномалиями, от которых во многом зависит прогноз заболевания.</p><p><bold>Материал и методы.</bold> Имеются единичные публикации, описывающие приёмы оперативного лечения пилорической атрезии с использованием внепросветных и внутрипросветных эндоскопических вмешательств, которые в настоящее время не позволяют судить об эффективности и безопасности данных методик у детей раннего возраста. Также в литературе представлены лишь единичные подробные обзоры клинических наблюдений пилорической атрезии, в большей части из которых описан I анатомический тип. Оперативное лечение атрезии привратника I типа заключается в мембранэктомии и последующей пилоропластике. Хирургический метод лечения пилорических атрезий II и III типов с резекцией зоны атрезии и формированием анастомоза между желудком и двенадцатиперстной кишкой влечёт за собой развитие осложнений из-за дуодено-гастрального рефлюкса в послеоперационном периоде. Для профилактики этих осложнений предложена методика, впервые представленная A. Dessantietal, позднее модифицированная и подробно описанная S. Yokoyamaetal. В настоящей публикации мы представляем краткий литературный обзор и наш опыт лечения атрезии привратника на примере 2 пациентов со II типом и 1 пациента с I типом атрезии привратника.</p><p><bold>Заключение.</bold> Выбор методики хирургического лечения зависит от анатомического варианта порока. В настоящее время единый подход к оперативной технике в случае атрезии II и III типов отсутствует. Мембранэктомия и гастродуоденоанастомоз, по-видимому, являются наиболее приемлемыми хирургическими техниками для исправления этой аномалии, что подтверждается предварительными данными настоящего исследования.</p></trans-abstract><kwd-group xml:lang="en"><kwd>pyloric atresia</kwd><kwd>epidermolysis bullosa</kwd><kwd>newborns</kwd><kwd>pyloroplasty</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>пилорическая атрезия</kwd><kwd>атрезия привратника</kwd><kwd>пилоропластика</kwd><kwd>буллезный эпидермолиз</kwd><kwd>новорождённые</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
