Two groups of patients were selected: group 1 – under 60 years old, group 2–60 years old and older. In the 2nd group, 2 subgroups were selected: patients aged between 60 to 74 years and patients between 75 years and older. The primary point of the study was assessment of postoperative complications according to the Clavien–Dindo classification within 30 days after surgery. The secondary point was study of oncological adequacy of the operation. <bold>Results.</bold> The study included 128 (56.4 %) women and 99 (43.6 %) men. The median age was 66 years. Forty seven (20.7 %) patients were included in the group of persons younger than 60 years; 180 (79.3 %) patients were included in the group 60 years and older. There were no differences between the groups by gender and tumor localization. Tumor perforation was more often recorded in group 2 (23.3 % and 4.3 %, <italic>p</italic> = 0.017). High comorbidity was also more often observed in group 2 (46.8 % and 100 %, <italic>p</italic> = 0.023). In group 2, the physical status mostly corresponded to ASA grade 3 and 4 (<italic>p</italic> = 0.031). The difference between the groups by T-status was revealed: in group 1, there were more cases of T2-T3 (76.6 % vs. 46.7 %), and in group 2 – of T4 (53.3 % vs. 23.4 %), <italic>p</italic> = 0.034. Most patients in group 1 had the pN2 status (68.1 %), however, the pN1 status prevailed in the 2<sup>nd</sup> group (70 %). There were more oncologically inadequate operations in group 2: 54 (30 %) compared with group 1–2 (4.3 %) (<italic>p</italic> = 0.004). The main factors influencing the radicality of the performed operation were the type of urgent complication – tumor perforation (odds ratio (OR) 1.81, 95 % CI 1.43–3.96, <italic>p</italic> = 0.002); type of surgery (the Hartmann type surgery) (OR 1.62, 95 % CI 1.22–3.83, <italic>p</italic> &lt;0.001); age OR 0.76, 95 % CI 0.54–1.33, <italic>p</italic> = 0.004); comorbidity (OR 0.61, 95 % CI 0.43–1.28, <italic>p</italic> = 0.02); physical status of patients according to ASA classification grade 3–4 at admission (OR 0.52, 95 % CI 0.30–1.49, <italic>p</italic> = 0.002); tumor localization (OR 0.43, 95 % CI 0.28–1.15, <italic>p</italic> = 0.011). <bold>Conclusion.</bold> Emergency operations for complicated colon cancer are characterized by a high risk of serious postoperative complications, especially in elderly and senile patients. In patients younger than 60 years of age, the malignant tumors are often characterized by more aggressive course with damage to regional lymph nodes (N2 status).</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель исследования</bold> – проведение сравнительного анализа клинико-морфологических данных пациентов разных возрастных групп после экстренных резекционных вмешательств по поводу осложненного рака ободочной кишки. <bold>Материалы и методы.</bold> В ретроспективное когортное исследование включены 227 пациентов, перенесших экстренные операции по поводу осложненного рака ободочной кишки за период с сентября 2016 г. по декабрь 2022 г. Выделены 2 группы пациентов: 1-я группа – до 60 лет, 2-я группа – 60 лет и старше. Во 2-й группе были выделены 2 подгруппы: пациенты в возрасте от 60 до 74 лет и пациенты 75 лет и старше. Первичная точка исследования – оценка послеоперационных осложнений по классификации Clavien–Dindo в течение 30 сут после операции. Вторичная точка – исследование онкологической адекватности операции. <bold>Результаты.</bold> В исследование включены 128 (56,4 %) женщин и 99 (43,6 %) мужчин. Медиана возраста составила 66 лет. В группу моложе 60 лет были включены 47 (20,7 %), в группу 60 лет и старше – 180 (79,3 %) пациентов. Различий между двумя группами по полу и локализации опухоли не выявлено. Перфорация опухоли чаще зафиксирована во 2-й группе (23,3 % и 4,3 %, <italic>p</italic> = 0,017). Высокая коморбидность чаще отмечалась также во 2-й группе (46,8 % и 100 %, <italic>p</italic> = 0,023). Во 2-й группе физический статус в основном соответствовал ASA 3 и 4 (<italic>p</italic> = 0,031). Выявлено различие между группами по T-статусу: в 1-й группе больше случаев T2–T3 (76,6 % против 46,7 %), а во 2-й группе – Т4 (53,3 % против 23,4 %), <italic>p</italic> = 0,034. большинство пациентов в 1-й группе имели статус pN2 (68,1 %), во 2-й группе преобладал статус pN1 (70 %). Во 2-й группе онкологически неадекватно выполненных операций было больше: 54 (30 %) по сравнению с 1-й группой – 2 (4,3 %) (<italic>p</italic> = 0,004). Основными факторами, оказавшими влияние на радикальность выполненной операции, явились вид ургентного осложнения – перфорация опухоли (отношение шансов (ОШ) 1,81, 95 % ДИ 1,43–3,96, <italic>p</italic> = 0,002); вид операции (операция по типу Гартмана) (ОШ 1,62, 95 % ДИ 1,22–3,83, р &lt;0,001); возраст (Ш 0,76, 95 % ДИ 0,54–1,33, <italic>p</italic> = 0,004); коморбидность (ОШ 0,61, 95 % ДИ 0,43–1,28, <italic>p</italic> = 0,02); физический статус пациентов при поступлении по классификации ASA 3–4 (ОШ 0,52, 95 % ДИ 0,3–1,49, <italic>p</italic> = 0,002); локализация опухоли (ОШ 0,43, 95 % ДИ 0,28–1,15, <italic>p</italic> = 0,011). <bold>Заключение.</bold> Экстренные операции при осложненном раке ободочной кишки характеризуются высоким риском серьезных послеоперационных осложнений, особенно у пациентов пожилого и старческого возраста. У пациентов моложе 60 лет злокачественные опухоли часто характеризуются более агрессивным течением с поражением регионарных лимфатических узлов (статус N2).</p></trans-abstract><kwd-group xml:lang="en"><kwd>complicated colon cancer</kwd><kwd>emergency operations</kwd><kwd>elderly and senile patients</kwd><kwd>clinical and morphological characteristics</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>осложненный рак ободочной кишки</kwd><kwd>экстренные операции</kwd><kwd>пациенты пожилого и старческого возраста</kwd><kwd>клинико-морфологические характеристики</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Russell A.M., Zhang J., Luz J. et al.
