Однако, несмотря на безопасность выполнения данных операций, проблема осложнений не теряет своей актуальности.</p></sec><sec><title>ЦЕЛЬ</title><p>ЦЕЛЬ: анализ накопленного опыта органосохраняющего лечения пациентов с крупными и гигантскими новообразованиями толстой кишки и определение факторов риска, ассоциированных с послеоперационными нежелательными явлениями.</p></sec><sec><title>ПАЦИЕНТЫ И МЕТОДЫ</title><p>ПАЦИЕНТЫ И МЕТОДЫ: за период с октября 2016 по июль 2024 года было выполнено 1858 эндоскопических операций. Из них 1191/1858 (64,1%) — подслизистых диссекций, 471/1858 (25,3%) новообразований было удалено методом эндоскопической резекции слизистой оболочки с циркулярным разрезом и 196/1858 (10,6%) — методом фрагментарной резекции слизистой оболочки с циркулярным разрезом. Медиана размеров удаленных новообразований составила 35 (25; 40) мм. Проанализированы данные по характеристикам пациентов и новообразований, длительности операций, морфологической принадлежности новообразований, частоте развития послеоперационных нежелательных событий. На основании полученных данных был выполнен расчет факторов риска развития нежелательных явлений после эндоскопического удаления новообразований толстой кишки.</p></sec><sec><title>РЕЗУЛЬТАТЫ</title><p>РЕЗУЛЬТАТЫ: в ходе проведенного анализа данных было выявлено, что послеоперационные нежелательные явления произошли у 275/1856 (14,8%) больных: кровотечение возникло в 33/1856 (1,8%) случаях, отсроченная перфорация произошла у 3/1856 (0,2%) пациентов. Посткоагуляционный синдром развился у 239/1856 (12,9%) пациентов. По результатам мультивариантного анализа был выявлен только один независимый предиктор развития посткоагуляционного синдрома — длительность операции. По результату ROC-анализа, проведенного на основании факторного анализа, было выявлено, что точкой отсечки является длительность операции ≥ 93 минут, площадь под ROC-кривой (AUC) = 0,93 ± 0,01 (p &lt; 0,001).</p></sec><sec><title>ВЫВОДЫ</title><p>ВЫВОДЫ: эндоскопическое удаление эпителиальных новообразований толстой кишки является безопасным. Наиболее частым нежелательным событием является посткоагуляционный синдром, требующий тщательного наблюдения в послеоперационном периоде для своевременного проведения дифференциальной диагностики, что позволит не пропустить более грозное осложнение, такое как отсроченная перфорация. Однако для профилактики развития посткоагуляционного синдрома необходимо проведение дальнейших исследований.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>AIM</title><p>AIM: to analyze the accumulated experience of organ-preserving treatment for large and gigantic colorectal neoplasms and to identify risk factors associated with postoperative adverse events.</p></sec><sec><title>PATIENTS AND METHODS</title><p>PATIENTS AND METHODS: 1,858 endoscopic operations were performed between October 2016 and July 2024. Of these, 1191/1858 (64.1%) had submucosal dissections, 471/1858 (25.3%) neoplasms were removed by endoscopic mucosal resection with a circular incision, and 196/1858 (10.6%) by fragmentary mucosal resection with a circular incision. The median size of the removed tumors was 35 (25; 40) mm. The data on the characteristics of patients and neoplasms, the operation time, the morphology and the rate of postoperative adverse events were analyzed. Based on the data obtained, the risk factors for adverse events after endoscopic removal of colon tumors were assessed.</p></sec><sec><title>RESULTS</title><p>RESULTS: postoperative adverse events occurred in 275/1856 (14.8%) patients: bleeding occurred in 33/1856 (1.8%) cases, delayed perforation occurred in 3/1856 (0.2%) patients. Postcoagulation syndrome developed in 239/1856 (12.9%) patients. According to the results of the multivariate analysis, only one independent predictor of the development of postcoagulation syndrome was identified — the duration of surgery. According to the result of the ROC analysis conducted on the basis of factor analysis, it was revealed that the cut-off point is the duration of the operation ≥ 93 minutes, the area under the ROC curve (AUC) = 0.93 ± 0.01 (p &lt; 0.001).</p></sec><sec><title>CONCLUSIONS</title><p>CONCLUSIONS: endoscopic removal of epithelial colorectal neoplasms is safe. The most common adverse event is postcoagulation syndrome, which requires careful monitoring in the postoperative period for timely differential diagnosis, which will make it possible not to miss a more serious complication, such as delayed perforation. However, further research is needed to prevent postcoagulation syndrome.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>нежелательные явления</kwd><kwd>осложнения</kwd><kwd>эндоскопическая подслизистая диссекция</kwd><kwd>ESD</kwd><kwd>C-EMR</kwd><kwd>C-EPMR</kwd><kwd>мукозэктомия с циркулярным разрезом</kwd><kwd>фрагментарная мукозэктомия с циркулярным разрезом</kwd></kwd-group><kwd-group xml:lang="en"><kwd>adverse events</kwd><kwd>complications</kwd><kwd>endoscopic submucosal dissection</kwd><kwd>ESD</kwd><kwd>C-EMR</kwd><kwd>C-EPMR</kwd><kwd>mucosectomy with circular incision</kwd><kwd>fragmentary mucosectomy with circular incision</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">Bretthauer M, et al.
