The frequency of POI after gynecological surgery averages 10–15% (range 5–25%). Chewing gum has been used in abdominal surgery and obstetric and gynecological practice to reduce postoperative intestinal obstruction since the beginning of the 21st century. The present review considers the main randomized clinical trials, reviews and meta-analyses devoted to the study of the effect of chewing gum after surgical interventions in obstetric and gynecological practice for the prevention of postoperative ileus. The data presented in the review indicate the effectiveness and safety of the use of chewing gum in the postoperative period for the prevention of postoperative ileus in obstetric and gynecological practice.</p></abstract><trans-abstract xml:lang="ru"><p>В акушерско-гинекологической практике после операций на брюшной полости возможно развитие динамической кишечной непроходимости, которая обозначается как послеоперационный илеус (ПОИ). Частота ПОИ после гинекологической операции составляет в среднем 10–15% (в диапазоне 5–25%). Жевательная резинка используется в абдоминальной хирургии и акушерско-гинекологической практике для уменьшения послеоперационной кишечной непроходимости с начала XXI в. В рамках представленного обзора рассмотрены основные рандомизированные клинические исследования, обзоры и метаанализы, посвященные изучению эффекта жевательной резинки после хирургических вмешательств в акушерско-гинекологической практике для профилактики ПОИ. Приведенные в обзоре данные свидетельствуют об эффективности и безопасности применения жевательной резинки в послеоперационном периоде для профилактики ПОИ в данной практике.</p></trans-abstract><kwd-group xml:lang="en"><kwd>obstetrics</kwd><kwd>gynecology</kwd><kwd>caesarean section</kwd><kwd>abdominal surgery</kwd><kwd>postoperative gastrointestinal paresis</kwd><kwd>postoperative ileus</kwd><kwd>prevention</kwd><kwd>chewing gum</kwd><kwd>flatus</kwd><kwd>defecation</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>акушерство</kwd><kwd>гинекология</kwd><kwd>кесарево сечение</kwd><kwd>абдоминальная хирургия</kwd><kwd>послеоперационный парез желудочно-кишечного тракта</kwd><kwd>послеоперационный илеус</kwd><kwd>профилактика</kwd><kwd>жевательная резинка</kwd><kwd>флатус</kwd><kwd>дефекация</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>van den Heijkant TC, Costes LM, van der Lee DG, et al.
