Namely, the frequency of early complications (seromas, protrusion/extrusion, infection), time for complete implant’s filling.</p><p><bold>Materials and methods.</bold> Retrospective review of 70 breast cancer patients, who underwent mastectomy with immediate breast reconstruction with textured expanders: 35 in prepectoral position (main group) and 35 in subpectoral position (control group). Inclusion criteria: no possibilities for breast-conserving surgery, indications for two-stage reconstruction and patient’s agreement. Extra criteria for the main group: rather good thickness of subcutaneous fat (PINCH-test ≥1.5 cm), no scars in operation region, good perfusion of flaps after mastectomy. Expansion with saline were in operation room firstly following it each 7–14 days. All expanders have been filled to the moment of direct results were estimated.</p><p><bold>Results and conclusion.</bold> Prepectoral position of tissue expander without using other devices for covering don’t rise the long-term seroma frequency, necessary time of postoperative drainage and expander loss risk (<italic>p</italic> ˃0.05). More comfortable and fast expander expansion to required volume in main group was the clear profit (<italic>p</italic> ≤0.05). Thus, according to our preliminary results prepectoral implantation of tissue expander without using other devices for covering in two-stage breast reconstruction after mastectomy can be the adequate choice in some patients.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> Возможности препекторальной установки тканевого экспандера без дополнительного укрытия на I этапе двухэтапной реконструкции после мастэктомии остаются неясными и иногда сомнительными.</p><p><bold>Цель исследования </bold>– проанализировать непосредственные результаты I этапа двухэтапной реконструкции молочной железы с использованием тканевого экспандера, установленного препекторально без дополнительного укрытия, а именно частоту ранних осложнений (сером, протрузий/экструзий, инфекционных осложнений), а также длительность и качество наполнения экспандера.</p><p><bold>Материалы и методы.</bold> Исследование носит ретроспективный характер. использованы данные 70 больных раком молочной железы, которым была выполнена мастэктомия с одномоментной установкой тканевого экспандера: 35 больным препекторально (основная группа) и 35 больным субпекторально (контрольная группа). Критерии включения в исследование: невозможность проведения органосохраняющей операции, наличие показаний и согласия больной для двухэтапной реконструкции. дополнительные критерии включения в основную группу: выраженность подкожной жировой клетчатки в зоне операции (PINCH-тест ≥1,5 см), отсутствие рубцовых изменений в зоне интереса, адекватная перфузия кожно-жировых лоскутов после мастэктомии. Наполнение физиологическим раствором проходило интраоперационно и каждые последующие 7–14 дней. На момент оценки непосредственных результатов экспандеры были наполнены полностью.</p><p><bold>Результаты и выводы.</bold> Препекторальное расположение экспандера без дополнительного укрытия не приводит к увеличению частоты развития длительных сером, не увеличивает необходимую длительность дренирования в послеоперационном периоде и не повышает риск потери экспандера (<italic>p</italic> ˃0,05). Как абсолютное преимущество установлено более комфортное и быстрое наполнение экспандера до нужного объема в основной группе (<italic>p</italic> ≤0,05). таким образом, по предварительным данным, препекторальная установка тканевого экспандера без дополнительного укрытия на I этапе двухэтапной реконструкции молочной железы после мастэктомии у определенной категории пациенток может быть обоснованным вариантом выбора.</p></trans-abstract><kwd-group xml:lang="en"><kwd>breast cancer</kwd><kwd>prepectoral reconstruction</kwd><kwd>two-stage reconstruction</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рак молочной железы</kwd><kwd>препекторальная реконструкция</kwd><kwd>двухэтапная реконструкция</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Nahabedian M.Y., Jacobson S.R.
