Методом «холодной» петлевой эксцизии при колоноскопии у 74 пациентов (22 мужчины и 52 женщины) в возрасте от 28 до 84 лет (средний возраст 59,3 ± 3,6 года) было удалено 103 образования толстой кишки: типа 0-IIа — 82 (79,7 %) и типа 0-Is — 21 (20,3 %), без признаков дисплазии тяжелой степени и рака. Проведен последующий эндоскопический анализ микроструктуры и капиллярных сосудов слизистой оболочки краев пострезекционного дефекта. Результаты анализа сравнивали с патологоанатомическим заключением.</p></sec><sec><title>Результаты</title><p>Результаты. Выявлены эндоскопические критерии радикально выполненной «холодной» полипэктомии: 1) в крае пострезекционного дефекта параллельно расположенные крипты; 2) структура кишечных ямок типа I (S. Kudo). Данные показатели наблюдались в 93 (90,3 %) случаях. Описаны признаки остаточной ткани — расширенные измененные крипты с нарушением параллельности их расположения, которые определены в 10 (9,7 %) случаях. Выявлено отличие пространственного расположения крипт в прямой кишке (эффект «падающих крипт»), которое затрудняет эндоскопическую диагностику нормальной ткани и остаточной ткани образования. При эндоскопической оценке строения сосудистого русла в слизистой оболочке толстой кишки определено, что плосковозвышенные образования типа 0-IIа имеют мелкую капиллярную сеть, что снижает риск кровотечения при удалении «холодным» способом. Динамическое наблюдение (диагностическая колоноскопия) было проведено 11 (10,7 %) пациентам, включая случай с образованием с тяжелой степенью дисплазии; развитых аденом, интервальных раков не выявлено.</p></sec><sec><title>Заключение</title><p>Заключение. Эндоскопическая оценка края пострезекционного дефекта после «холодной» полипэктомии эпителиального образования толстой кишки позволяет обеспечить надежную диагностику радикальности проведенного эндоскопического вмешательства и возможность удаления остаточной ткани (если она имеется) сразу после его завершения, что способствует снижению частоты рецидива.</p></sec></abstract><trans-abstract xml:lang="en"><p>The aim of this study was to assess the usefulness of endoscopic removal of small (less than 10 mm) colon polyps with a cold snare on the basis of endoscopic microstructural analysis of the edges of the post-resection defect using high-resolution video endoscopic equipment.</p><sec><title>Methods</title><p>Methods. In 74 patients (22 men and 52 women) aged 28 to 84 years (average age 59.3 ± 3.6 years), 103 colon polyps of types 0-IIa — 82 (79.7 %) and 0-Is — 21 (20.3 %), without the signs of severe dysplasia and cancer, were removed through the endoscope by the using of a cold snare, followed by mandatory inspection of the edges of the post-resection defect. A complete endoscopic analysis of the microstructures and the capillary vessels of the mucosa was performed on the edge of the post-resection defect, and then was compared to the histological image.</p></sec><sec><title>Results</title><p>Results. The endoscopic criteria for completely performed cold snare resection were identified, they are parallel crypts and the structure of intestinal pits of type I (S. Kudo) in the edge of the post-resection defect, which were observed in 93 (90.3 %) cases. Signs of residual tissue were dilated altered crypts with a violation of the parallelism of their location, which were observed in 10 (9.7 %) cases. The difference between the spatial location of crypts in the rectum (the effect of “falling crypts”) was identified, which complicates the differential diagnosis of normal and residual tumor tissue. In the endoscopic diagnosis of the vascular pattern of the colon mucosa was determined that flat-elevated polyps have a fine capillary network, which reduces the risk of bleeding when use a cold resection method. An observation (diagnostic colonoscopy) was performed in 11 (10.7 %) patients, including a case with the polyp with high grade displasia. No advance adenomas and interval cancers were detected.</p></sec><sec><title>Conclusion</title><p>Conclusion. Тhis research helps to ensure reliable diagnosis of the completeness of performed endoscopic intervention and the possibility of removal of residual tumor tissue (if present) immediately after its completion, it’s allow a reduction in the number of recurrences of tumors.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>полипэктомия</kwd><kwd>колоноскопия</kwd><kwd>пострезекционный дефект</kwd><kwd>кишечная крипта</kwd></kwd-group><kwd-group xml:lang="en"><kwd>polypectomy</kwd><kwd>colonoscopy</kwd><kwd>post-resection defect</kwd><kwd>colon crypt</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">Zauber A.G., Winawer S.J., O’Brien M.J., Lansdorp-Vogelaar I., van Ballegooijen M., Hankey B.F., et al.
