The tendency to the wide implementation of the enhanced recovery after surgery (ERAS) protocol in the clinical practice leads to the increased requirement in surgical safety that can be provided with the possible earliest detection of postoperative complications and appropriate treatment. This requirement is the most acute in gastric cancer surgery, where despite the improvement of surgical techniques and complex treatment approach the rate of postoperative complications and esophagojejunal anastomotic leakage (EAL) is still high, making up 27% and 10%, respectively. The measurement of C-reactive protein (CRP) concentration in blood plasma is the simplest, most accessible and reliable method to detect infectious complications. However, CRP concentrations, which may indicate the development of postoperative complications, differ significantly in different studies.The aim of the study was to specify the role of CRP as a predictive biomarker for infectious complications and esophagojejunal anastomotic leakage.Materials and methods. This retrospective study included immediate outcomes of the planned radical gastrectomy in 130 patients. The CRP level was assessed depending on the complication type in the immediate postoperative period. Correlation between CRP levels and the incidence of postoperative infectious complications was analyzed. The severity grade of postoperative complications was registered according to the modified Clavien-Dindo classification. The statistical analysis was performed using parametrical and non-parametrical methods. The optimal cut-off CRP for infectious complications and anastomotic leakage was defined with the use of the ROC analysis. The multifactorial ANOVA was performed to detect the effect of contributing factors on the CRP level.Results. An increase in CRP levels over 100 mg/L on the fourth day after surgery can be considered as a manifestation of infectious complications (AUC 0,866 ± 0,042, 95% CI: 0,798-0,934, p &lt;0,001), and an increase in CRP levels over 167 mg/L on the fifth day is a predictor of the development of EAL (AUC 0,869 ± 0,081, 95% CI: 0,711-1,000, p = 0,001). Initial malnutrition and aggravated somatic status appear to be risk factors for the development of infectious complications (p &lt;0,001).Conclusion. Therefore, despite its low specificity, CRP is a sensitive marker of postoperative infectious complications starting from the first days of the postoperative period. Evaluation of the CRP concentration in dynamics allows identifying postoperative complications before the development of clinical manifestations.</p></abstract><trans-abstract xml:lang="ru"><p><bold><italic>Обоснование</italic></bold><bold>. </bold>Тенденция к широкому внедрению в клиническую практику программы ускоренного восстановления (ПУВ) диктует повышенные требования к хирургической безопасности, которая обеспечивается максимально ранним выявлением осложнений и изменением тактики лечения. Особенно это требование актуально в хирургии рака желудка (РЖ), где, несмотря на совершенствование оперативных методик и комплексному подходу, частота послеоперационных осложнений и несостоятельности эзофагоеюноанастомоза (ЭЕА) остаются крайне высокими, достигая 27% и 10% соответственно. Наиболее простым, доступным и в тоже время надёжным методом лабораторной диагностики инфекционных осложнений в послеоперационном периоде является определение концентрации С-реактивного белка (C-РБ) в плазме крови. Однако, концентрации C-РБ, которые могут указывать на развитие послеоперационных осложнений, значительно различаются в разных публикациях.</p> <p><bold><italic>Цель</italic></bold><bold>.</bold> Уточнение роли С-РБ в ранней диагностике инфекционных осложнений и несостоятельности ЭЕА.</p> <p><bold><italic>Методы</italic></bold><bold>.</bold> Проведено ретроспективное исследование ближайших результатов плановой радикальной гастрэктомии у 130 пациентов. Оценивался уровень С-РБ в зависимости от характера осложнений в ближайшем послеоперационном периоде. Проанализирована взаимосвязь уровня С-РБ и развития инфекционных осложнений и несостоятельности ЭЕА в послеоперационном периоде. Тяжесть послеоперационных осложнений регистрировалась в соответствии с модифицированной шкалой Clavien-Dindo. Статистическая обработка данных проводилась параметрическими и непараметрическими методами анализа. Выбор оптимальных пороговых значений С-РБ при развитии инфекционных осложнений и несостоятельности ЭЕА оценивали с помощью ROC-анализа. Влияние факторов на уровень С-РБ оценивалось с помощью многофакторного дисперсионного анализа.</p> <p><bold><italic>Результаты</italic></bold><bold>.</bold> Повышение уровня С-РБ выше 100 мг/л на четвёртые сутки после операции можно рассматривать, как проявление инфекционных осложнений (AUC 0,866±0,042, 95% ДИ: 0,798-0,934, p&lt;0,001), а повышение уровня С-РБ выше 167 мг/л на пятые сутки является предиктором развития несостоятельности ЭЕА (AUC 0,869±0,081, 95% ДИ: 0,711-1,000, p = 0,001). Исходная недостаточность питания и отягощенный соматический статус являются факторами риска развития инфекционных осложнений (p&lt;0,001).</p> <p><bold><italic>Заключение</italic></bold><bold>. </bold>С-РБ, несмотря на низкую специфичность, является чувствительным маркёром послеоперационных инфекционных осложнений, начиная с первых дней послеоперационнного периода. Оценка концентрации С-РБ в динамике позволяет выявить послеоперационные осложнения до развития клинических проявлений.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Gastric cancer</kwd><kwd>gastrectomy</kwd><kwd>enhanced recovery after surgery</kwd><kwd>C-reactive protein</kwd><kwd>postoperative complication</kwd><kwd>anastomotic leakage</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>Рак желудка</kwd><kwd>гастрэктомия</kwd><kwd>программа ускоренного восстановления</kwd><kwd>С-реактивный белок</kwd><kwd>послеоперационные осложнения</kwd><kwd>несостоятельность анастомоза</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
