In the retrospective analysis, we studied the structure of complications after delayed reconstructive surgeries of type 0-II pharyngeal and pharyngo-esophageal defects. Local tissue, pectoral flap, and deltopectoral flap were used as plastic material. Complications in the postoperative period were observed in all types of plasty.</p> <p><bold>Results.</bold> The most frequent complications included inflammation of the postoperative wound, anastomosis failure with subsequent formation of fistulas or secondary faryngostomas. In type 0 pharyngeal defects, plastic surgery with the use of local tissues showed a good result, postoperative complications occurred in 11% of cases. In I type pharyngeal defects, fistulas and secondary stomas in the postoperative period were formed in 83% of cases when local tissues were used, in 45.8% when pectoral flap was used and in 66.5% when deltopectoral flap was used. In type II of the defect, the percentage of postoperative complications when using a pectoral flap was 75% and deltopectoral flap – 100%.</p> <p><bold>Conclusion. </bold>Complications in the postoperative period were observed in all types of plasty. The study of risk factors and creation of the algorithm for selection of patients for delayed plasty will allow to determine the terms and indications for delayed reconstructive-reconstructive surgery, as well as to reasonably reduce the risk of postoperative complications.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель</bold> – провести ретроспективный анализ результатов хирургического лечения отсроченных реконструкций дефектов глотки у пациентов с распространенным раком гортани и гортаноглотки после ларингэктомии.</p> <p><bold>Материал и методы. </bold>Проведен ретроспективный анализ 437 историй болезни пациентов, прошедших лечение в СОКОД в период 2015–2019 гг. со злокачественными новообразованиями гортани и гортанного отдела глотки, которым ранее были выполнены комбинированные и расширенно-комбинированные ларингэктомии. При ретроспективном анализе нами была изучена структура осложнений после отсроченных реконструктивных операций фарингеальных и фарингоэзофагеальных дефектов 0-II типов. В качестве пластического материала применялись местные ткани, пекторальный лоскут, дельтопекторальный лоскут. При всех видах пластики наблюдались осложнения в послеоперационном периоде.</p> <p><bold>Результаты.</bold> Наиболее частыми осложнениями являлись воспаление послеоперационной раны, несостоятельность анастомоза с последующим формированием свищей или рефарингостом. При 0 типе дефекта глотки хороший результат показала пластика с использований местных тканей, послеоперационные осложнения возникли в 11% случаев. При I типе дефекта глотки свищи и рестомы в послеоперационном периоде сформировались в 83% случаев при использовании местных тканей, в 45,8% – при использовании пекторального лоскута и в 66,5% – при использовании дельтопекторального лоскута. При II типе дефекта процент послеоперационных осложнений при применении пекторального лоскута составил 75% и дельтопекторального лоскута – 100%.</p> <p><bold>Заключение. </bold>При всех видах пластики наблюдались осложнения в послеоперационном периоде. Изучение факторов риска и создание алгоритма отбора пациентов позволит определить сроки и показания к отсроченной реконструктивно-восстановительной операции, а также обоснованно снизить риск послеоперационных осложнений.</p></trans-abstract><kwd-group xml:lang="en"><kwd>laryngeal cancer</kwd><kwd>laryngopharyngeal cancer</kwd><kwd>pectoral flap</kwd><kwd>deltopectoral flap</kwd><kwd>plastic material</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рак гортани</kwd><kwd>рак гортаноглотки</kwd><kwd>пекторальный лоскут</kwd><kwd>дельтопекторальный лоскут</kwd><kwd>пластический материал</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Malignant neoplasms in Russia in 2022 (morbidity and mortality).
