Однако она сопряжена с риском развития послеоперационных осложнений. С целью снижения частоты осложнений альтернативной методикой представляется «холодная» эксцизия.</p></sec><sec><title>Цель</title><p>Цель: улучшение результатов эндоскопического лечения больных с эпителиальными образованиями толстой кишки.</p></sec><sec><title>Пациенты и методы</title><p>Пациенты и методы: с сентября 2019 г. по сентябрь 2020 г. в проспективное рандомизированное сравнительное исследование включено 160 пациентов ≥ 18 лет (80 человек в каждой из групп), которым было выполнено эндоскопическое удаление полипов толстой кишки размерами ≤ 10 мм «холодной» эксцизией (132 образования) и методикой электроэксцизии (129 образований). Все извлеченные операционные препараты подвергались патоморфологическому исследованию с оценкой радикальности удаления (R0/R1). Проведен факторный анализ частоты послеоперационных осложнений после эндоскопической электроэксцизии и частоты получения Rx резекции после удаления полипов обеими методиками.</p></sec><sec><title>Результаты</title><p>Результаты: сравниваемые группы были сопоставимы по количеству пациентов, полу, возрасту, наличию у них сопутствующих заболеваний. Время удаления полипов методикой электроэксцизии было статистически значимо выше времени при «холодной» эксцизии (p = 0,0001). Значимых различий в частоте возникновения интраоперационных осложнений при обеих методиках получено не было (p = 0,06). В группе «холодной» эксцизии послеоперационных осложнений зарегистрировано не было. В группе электроэксцизии послеоперационные осложнения развились после удаления 12/129 полипов (p = 0,001). При унивариантом анализе выявлено, что фактором риска развития послеоперационных осложнений после эндоскопической электроэксцизии является невыполнение лифтинга образования (ОШ: 15,3, 95% ДИ: 1,9–125,6, р = 0,01). Патоморфологическое исследование операционных препаратов показало, что в обеих группах большинство вмешательств были признаны R0 резекциями (54% — в основной группе, 56,4% — в контрольной, p = 0,8). Фактором риска получения R1 и Rx резекции выявлен размер эпителиального образования ≤ 4 мм (ОШ: 2,4, 95% ДИ: 1,3–4,7, р = 0,007).</p></sec><sec><title>Заключение</title><p>Заключение: «холодная» эксцизия является эффективной и безопасной процедурой и может быть методом выбора при полипах не более 10 мм.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background: endoscopic electroexcision is the standard technique for the removal of colorectal polyps. However, it is associated with the postoperative morbidity. In order to reduce the incidence of complications, “cold” excision seems to be an alternative option.</p></sec><sec><title>Aim</title><p>Aim: to improve the results of endoscopic treatment for patients with colorectal polyps.</p></sec><sec><title>Patients and methods</title><p>Patients and methods: from September 2019 to September 2020, 160 patients ≥ 18 years old (80 in each group), who underwent endoscopic removal of colorectal polyps ≤ 10 mm in size by cold excision (132 lesions) and traditional polypectomy (129 lesions), were included in a prospective randomized trial. All removed specimens were studied histologically with an assessment of the resection margins (R0/R1). The analysis of the postoperative complications after endoscopic polypectomy and the incidence of Rx resection after removal of polyps by both techniques was done.</p></sec><sec><title>Results</title><p>Results: the compared groups were homogenous in the number of patients, gender, age, and comobridities. There were no significant differences in the number of removed polyps, their site and the type according to endoscopic classifications. The operation time was significantly higher in the conventional polypectomy group compared with the “cold” one (p = 0.0001). There were no significant differences in the intraoperative complications rate between the two groups (p = 0.06). There were no postoperative complications in the “cold” group. In the control group postoperative complications occurred after 12 out of 129 polyps removal (p = 0.001). The univariate analysis showed that a risk factor for the development of postoperative complications after conventional polypectomy is the lack of submucosal lifting (OR: 15.3, 95% CI: 1.9-125.6, p = 0.01). Histopathology of the removed specimens showed that in both groups most of the procedures were considered as R0 resections (54% in the main group, 56.4% in the control group, p = 0.8). The polyp size ≤ 4 mm identified as a risk factor for R1, Rx resection (OR: 2.4, 95% CI: 1.3–4.7, p = 0.007).</p></sec><sec><title>Conclusion</title><p>Conclusion: “cold” polypectomy is an effective and safe method and may be recommended as an alternative technique for the removal of non-pedunculated colorectal polyps ≤ 10 mm.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>полипы толстой кишки</kwd><kwd>«холодная» полипэктомия</kwd><kwd>электроэксцизия</kwd><kwd>R0 резекция</kwd><kwd>постполипэктомические осложнения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>small colorectal polyps</kwd><kwd>colonoscopy</kwd><kwd>cold and hot snare polypectomy</kwd><kwd>resection rate</kwd><kwd>postpolypectomy symptoms</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">Phipps AI, Scoggins J, Rossing MA, et al.
