В исследование были включены 668 пациентов, которым было выполнено эндоскопическое внутрипросветное удаление поверхностных эпителиальных новообразований толстой кишки в ГБУЗ «Нижегородский областной онкологический диспансер» в период с 2012 по 2020 годы. В работу включены пациенты, у которых были выявлены крупные эпителиальные доброкачественные и злокачественные (с глубиной инвазии в пределах слизистой оболочки) новообразования толстой кишки размерами 20 и более мм. Их средний размер составил 35,5±0,68 мм (медиана - 30 мм). В ходе проведенного нами анализа были выявлены факторы, ассоциированные с повышенным риском развития рецидива эпителиальных новообразований после их внутрипросветного эндоскопического удаления. В первую очередь, к ним относятся локализация опухоли в нисходящей части ободочной и прямой кишке, а также ее плоско-возвышающийся макроскопический тип (тип IIа по Парижской классификации). Гистологическое строение новообразования - УДАК, также достоверно сопряжено с высоким риском его рецидивирования. Применение методики ЭДПС, завершенной петлевой резекцией повышает риски развития остаточной опухоли в 3 раза. С учетом отсутствия данных за наличие местного рецидива после проведения модифицированной ЭДПС “String-to-ring”, мы считаем целесообразным дальнейшее внедрение в практику этой методики, особенно - с целью удаления новообразований, чьи характеристики сопряжены с высокими рисками развития рецидива после классических вариантов эндоскопических вмешательств.</p></abstract><trans-abstract xml:lang="en"><p>Based on current data on the risks of recurrence of colon epithelial neoplasms after their endoscopic removal, it is advisable to identify its predictors, which was the aim of our study. The study included 668 patients, who underwent endoscopic resection of superficial colonic epithelial neoplasms in the Nizhny Novgorod Regional Oncology Dispensary from 2012 to 2020. The study included patients who were diagnosed with large epithelial benign and malignant (with an invasion depth within the mucosa) neoplasms of the colon measuring 20 mm or more. Their average size was 35.5 ± 0.68 mm (median - 30 mm). During data analysis, we identified factors, associated with an increased risk of recurrence of epithelial neoplasms after their intraluminal endoscopic resection. First of all, these include the localization of the tumor in the descending colon and rectum, as well as its elevated flat type (type IIa according to the Paris classification). The histological type of the neoplasm - moderately differentiated adenocarcinoma, is also reliably associated with a high risk of its recurrence. The use of ESD, completed by endoscopic loop resection, increases the risk of developing a residual tumor threefold. According to our data on the absence of local relapse after the modified ESD “String-to-ring”, we consider it appropriate to further use this technique in everyday practice, especially for the removal high-risk neoplasms.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рецидив</kwd><kwd>аденома толстой кишки</kwd><kwd>эндоскопическая диссекция в подслизистом слое</kwd><kwd>эндоскопическая резекция новообразования</kwd></kwd-group><kwd-group xml:lang="en"><kwd>recurrence</kwd><kwd>colon adenoma</kwd><kwd>ESD</kwd><kwd>EMR</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">Sullivan B.A., Noujaim M., Roper J.
