Разработка, валидация и программная реализация клинико-лабораторной модели на основе машинного обучения (ML) для раннего выявления и своевременной профилактики послеоперационных осложнений у пациентов, перенесших бариатрические вмешательства.МЕТОДЫ И МАТЕРИАЛЫ. Выполнен ретроспективный анализ клинических данных 2011 пациентов, перенесших бариатрическую операцию. В исследование были включены демографические параметры, клинические симптомы, лабораторные показатели, данные визуализации, а также сведения о течении послеоперационного периода. Построена модель логистической регрессии с применением автоматического взвешивания классов, что позволило скорректировать дисбаланс классов и повысить точность предсказаний. Эффективность модели оценивалась по основным метрикам: AUC, точность, чувствительность, специфичность и F1-score.РЕЗУЛЬТАТЫ. Разработанная модель продемонстрировала высокую прогностическую точность (AUC=0,975, точность 94,8 %, чувствительность 93,1 %). Наиболее значимыми признаками для классификации осложнений оказались уровни С-реактивного белка, тахикардия, лихорадка, выраженность симптомов и лабораторные маркеры воспаления.ЗАКЛЮЧЕНИЕ. Представленная модель машинного обучения имеет высокий потенциал для интеграции в клиническую практику и может стать основой для создания интеллектуальных систем раннего предупреждения осложнений, автоматизированного мониторинга и поддержки принятия врачебных решений. </p></abstract><trans-abstract xml:lang="en"><p>The OBJECTIVE was to develop, validate, and implement a clinical and laboratory model based on machine learning (ML) for the early identification and timely prevention of postoperative complications in patients who have undergone bariatric surgery.METHODS AND MATERIALS. A retrospective analysis was performed on clinical data from 2,011 patients who underwent bariatric procedures. The study included demographic characteristics, clinical symptoms, laboratory findings, imaging results, and details of the postoperative course. A logistic regression model was constructed using automatic class weighting to correct for class imbalance and improve predictive accuracy. The model’s performance was evaluated using key metrics: AUC, accuracy, sensitivity, specificity, and F1-score.RESULTS. The developed model demonstrated high predictive performance (AUC=0.975, accuracy=94.8 %, sensitivity=93.1 %). The most significant predictors of postoperative complications were elevated C-reactive protein levels, tachycardia, fever, symptom severity, and inflammatory laboratory markers.CONCLUSION. The proposed machine learning model shows substantial potential for integration into clinical practice and may serve as a foundation for developing intelligent systems for early complication warning, automated monitoring, and clinical decision support.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>бариатрическая хирургия</kwd><kwd>послеоперационные осложнения</kwd><kwd>машинное обучение</kwd><kwd>искусственный интеллект</kwd><kwd>прогностическая модель</kwd></kwd-group><kwd-group xml:lang="en"><kwd>bariatric surgery</kwd><kwd>postoperative complications</kwd><kwd>machine learning</kwd><kwd>artificial intelligence</kwd><kwd>predictive model</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Sheikhtaheri A., Orooji A., Pazouki A. et al.
