Критериями включения в исследование было наличие доброкачественной опухоли толстой кишки 20 мм и более, удаленной методикой ФЭРСО.</p></sec><sec><title>РЕЗУЛЬТАТЫ</title><p>РЕЗУЛЬТАТЫ: Установлено, что осложнения при выполнении ФЭРСО возникли в 13% случаях. В 9,2% – интраоперационные кровотечения, остановленные с помощью эндоскопических методик. В 1,2% пациентов было зарегистрировано послеоперационное кровотечение, в 2,4% случаев – перфорация. В 12% случаев диагностирован рецидив опухоли.Была выявлена прямая корреляционная связь между рецидивом опухоли и фактом интраоперационного кровотечения (р=0,013) и размером более четырех сантиметров (р=0,012); обратная корреляционная связь между рецидивом опухоли полнотой лифтинга в ходе выполнения ее удаления (р=0,008) и мужским полом пациента (р=0,043).</p></sec><sec><title>ЗАКЛЮЧЕНИЕ</title><p>ЗАКЛЮЧЕНИЕ: Выделены значимые риски рецидива опухоли в послеоперационный период. Эти факторы могут быть частично учтены на этапе составления плана лечения каждого пациента (пол и размер опухоли), а частично при выполнении самой лечебной манипуляции (полнота лифтинга и наличие факта интраоперационного кровотечения). При этом не требуются какие-либо дополнительные финансовые и временные затраты.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>AIM</title><p>AIM: to assess the safety of endoscopic piecemeal mucosal resection (EPMR) of large epithelial colorectal lesions and to identify risk factors for tumor recurrence.</p></sec><sec><title>PATIENTS AND METHODS</title><p>PATIENTS AND METHODS: results of EPMR were evaluated in retrospective study, which was carried out in five regional endoscopic centers.
