Only patients with favorable prognosis (tumor located at least 5 cm above the transitional anal fold and no history of chemoradiotherapy) were included. The primary outcome measure was the incidence of peritonitis and colorectal anastomosis leakage. Secondary outcome measures included overall incidence of complications (Clavien–Dindo), mortality rate, blood loss, and duration of surgery.<bold>Results.</bold> A total of 120 patients were included into the experimental group, while the control group was composed of 125 patients. Ten patients from the control group developed peritonitis (8.0 %), whereas in the experimental group, there were no cases of peritonitis (p = 0.002). Anastomotic leakage was registered in 12 individuals from the experimental group (12.5 %) and 14 controls (11.2 %) (p = 0.753). The overall incidence of postoperative complications was 23.3 % (n = 28) among patients who had pelvic peritoneal floor reconstruction and 18.4 % (n = 23) among those who did not have it (p = 0.342). Colostomy was required in 92 patients from the experimental group (76.7 %) and 78 patients from the control group (62.4 %) (p = 0.018). The postoperative mortality was 0.8 % in the control group (n = 1) and 0 % in the experimental group (p = 1).<bold>Conclusion.</bold> Pelvic peritoneal floor reconstruction reduces the risk of peritonitis, but does not affect the overall risk of anastomotic leakage. This method is effective for the prevention of severe postoperative complications.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> Несостоятельность колоректального анастомоза остается одной из основных проблем хирургии рака прямой кишки.<bold>Цель исследования</bold> – оценить влияние восстановления тазовой брюшины на снижение частоты послеоперационных осложнений, связанных с колоректальным анастомозом.<bold>Материалы и методы.</bold> В ретроспективном когортном исследовании проанализированы данные историй болезни пациентов, которым выполнялась резекция прямой кишки по поводу рака прямой кишки с формированием анастомоза в период 2013–2020 гг. сравнивали пациентов, которым не проводили восстановление тазовой брюшины (с 2013 по 2017 г.), и пациентов, которым тазовая брюшина была восстановлена (2018–2020 гг.). Включали пациентов с благоприятными прогностическими факторами (локализация опухоли выше 5 см от переходной анальной складки, отсутствие предшествующей химиолучевой терапии). Основным оцениваемым параметром была частота перитонитов при развитии несостоятельности колоректального анастомоза, дополнительными оцениваемыми параметрами – общая частота осложнений (по Clavien–Dindo), летальность, кровопотеря, длительность операции.<bold>Результаты.</bold> В основную группу было включено 120 пациентов, в контрольную – 125. В исследуемой группе перитонитов не было, в контрольной группе – 10 (8,0 %) случаев (p = 0,002). Общая частота развития несостоятельности анастомоза в исследуемой группе – 15 (12,5 %) случаев, в контрольной – 14 (11,2 %) случаев (p = 0,753); общая частота осложнений в исследуемой группе – 28 (23,3 %) случаев, в контрольной – 23 (18,4 %) случая (p = 0,342); частота формирования кишечных стом в исследуемой группе – 92 (76,7 %) случая, в контрольной – 78 (62,4 %) случаев (p = 0,018). Послеоперационная летальность составила 1 (0,8 %) случай в контрольной группе, в то время как в исследуемой группе послеоперационной летальности не зафиксировано (p = 1).<bold>Выводы.</bold> Восстановление тазовой брюшины достоверно снижает риск развития перитонита, но не общий риск развития несостоятельности анастомоза. данный метод эффективен в профилактике тяжелых послеоперационных осложнений.</p></trans-abstract><kwd-group xml:lang="en"><kwd>rectal cancer</kwd><kwd>rectal resection</kwd><kwd>laparoscopic rectal resection</kwd><kwd>anastomotic leakage</kwd><kwd>pelvic peritoneal floor reconstruction</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рак прямой кишки</kwd><kwd>резекция прямой кишки</kwd><kwd>лапароскопическая резекция прямой кишки</kwd><kwd>несостоятельность анастомоза</kwd><kwd>восстановление тазовой брюшины</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">1.
