This localization of gastrointestinal duplications is the rarest and is not described in the domestic literature.</p> <p><bold><italic>AIM: </italic></bold>This study aimed to present the experience of the management of periampullary duodenal duplication cysts in children.</p> <p><bold><italic>CASES REPORT:</italic> </bold>Seven children with periampullary duodenal duplication cysts underwent surgery between 2007 and 2022. All patients suffered from prolonged abdominal pain, vomiting of food, and bile. Two children had recurrent pancreatitis, and one child underwent repeated operations for high intestinal obstruction and biliary obstruction in other hospitals. An abdominal cyst was suspected in one patient at another hospital, and the child underwent exploratory laparoscopy, but no formation was found. Ultrasound, gastroduodenoscopy, computed tomography, and magnetic resonance imaging were performed on these children. Ultrasound examination showed a peristaltic cystic formation up to 4 cm in diameter with a double wall. Gastroduodenoscopy showed formation in the second portion of the duodenum in the region of the major duodenal papilla. This formation covers the intestinal lumen by two-thirds and up to nearly complete obturation. The relationship between duodenal duplication and the bile and pancreatic ducts was clarified on magnetic resonance cholangiopancreatography: the relationship was suspected in two children. All patients underwent wide transduodenal excision of periampullary duodenal duplication cyst; in four cases, laparoscopic access was used. No intra- and postoperative complications occurred. Histological examination revealed true duplications in all cases. The children were discharged on days 11–12. In the follow-up after 3 months and 10 years, no complications were noted.</p> <p><bold><italic>CONCLUSIONS:</italic></bold> Periampullary duodenal duplication cysts can be a cause of chronic duodenal obstruction. Transduodenal excision of periampullary duodenal duplication cysts is the optimal treatment, and this operation can be performed laparoscopically.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> Причиной обтурационного варианта хронической дуоденальной непроходимости могут быть врожденные пороки развития двенадцатиперстной кишки, например, парафатериальные кистозные удвоения. Данная локализация удвоений кишечной трубки является наиболее редкой и не описана в отечественных источниках.</p> <p><bold>Цель</bold> — представить опыт лечения детей с парафатериальными кистозными удвоениями двенадцатиперстной кишки.</p> <p><bold>Описание наблюдений.</bold> С 2007 по 2022 г. было прооперировано 7 детей с парафатериальными кистозными удвоениями двенадцатиперстной кишки. У всех пациентов отмечались жалобы на длительные периодические боли в животе, рвоту съеденной накануне пищей с желчью. Рецидивирующий панкреатит диагностирован у 2 детей. Один ребенок ранее перенес неоднократные оперативные вмешательства в других клиниках по поводу развития высокой кишечной непроходимости и билиарной обструкции. Еще у одного пациента в другом лечебном учреждении была заподозрена киста брюшной полости, выполнена диагностическая лапароскопия, однако образование найдено не было. При поступлении пациентам проведено комплексное обследование, включающее ультразвуковое исследование, фиброгастродуоденоскопию, спиральную компьютерную томографию и магнито-резонансную холангиопанкреатографию. При ультразвуковом исследовании выявлено перистальтирующее кистозное образование до 4 см в диаметре с двухконтурной стенкой. На фиброгастродуоденоскопии в просвете нисходящей ветви двенадцатиперстной кишки в области большого дуоденального сосочка визуализировано объемное образование, перекрывающее просвет кишки от 2/3 до практически полной ее обтурации. Наличие связи удвоения двенадцатиперстной кишки с желчными и панкреатическими протоками уточняли на магниторезонансной холангиопанкреатографии: связь была заподозрена у двоих детей. Всем детям выполнено трансдуоденальное широкое иссечение парафатериального кистозного удвоения, при этом в 4 случаях использовали лапароскопический доступ. Интра- и послеоперационных осложнений не было. Микроскопическая картина во всех наблюдениях соответствовала истинным удвоениям. Пациенты выписаны на 11–12-е сутки. В катамнезе через 3 мес. – 10 лет осложнений не отмечено.</p> <p><bold>Заключение.</bold> Парафатериальные кистозные удвоения могут быть причиной хронической дуоденальной непроходимости у детей. Операцией выбора считается трансдуоденальное иссечение парафатериального кистозного удвоения двенадцатиперстной кишки, которое может быть выполнено лапароскопическим доступом.</p></trans-abstract><kwd-group xml:lang="en"><kwd>periampullary duodenal duplication cysts</kwd><kwd>chronic duodenal obstruction</kwd><kwd>duodenum</kwd><kwd>children</kwd><kwd>laparoscopy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>парафатериальные кистозные удвоения двенадцатиперстной кишки</kwd><kwd>хроническая дуоденальная непроходимость</kwd><kwd>двенадцатиперстная кишка</kwd><kwd>дети</kwd><kwd>лапароскопия</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">Chen J-J, Lee H-C, Yeung C-Y, et al.
