Применение такого технического приема при ЭПД, как создание тоннеля («кармана») в подслизистом слое под опухолью, создает условия для улучшения качества операционного препарата и снижения частоты его фрагментации.ЦЕЛЬ ИССЛЕДОВАНИЯ: изучить эффективность и безопасность тоннельной ЭПД (ТЭПД) в сравнении с классической ЭПД (КЭПД) при лечении аденом и ранних форм рака толстой кишки.МАТЕРИАЛЫ И МЕТОДЫ: поиск литературы и мета-анализ производился в соответствии с рекомендациями PRISMA при помощи поисковой системы PUBMED в электронной базе Medline без ограничения даты публикации среди англоязычной литературы. В систематический обзор включены все исследования, посвященные сравнению тоннельного и классического методов ЭПД.РЕЗУЛЬТАТЫ: в анализ включены 4 исследования (1422 больных, 458 в группе ТЭПД и 961 в группе КЭПД). Группы были сопоставимы по количеству аденом (ОШ=1,25; 95% ДИ=0.87-1,79; p=0,22), аденокарцином (ОШ=0,96; 95% ДИ=0,49-1,87; p=0,90),по размерам новообразований (95% ДИ=-6,26-1,22; p=0,19) и по наличию подслизистого фиброза (p=0,69). По частоте интраоперационных кровотечений (ОШ=1,24; 95% ДИ 0,53-2,88; p=0,61) достоверных различий получено не было, однако, перфорации чаще возникали при использовании КЭПД (ОШ=0,35; 95% ДИ=0,15-0,83; p=0,02). КЭПД занимал достоверно больше времени в сравнении с ТЭПД (ОШ=-19,1; 95% ДИ=-33,89-4,45; p=0,01). Частота резекций en bloc (ОШ= 16,06; 95% ДИ=4,95-52,11; p&lt;0,0001) и R0-резекций (ОШ=3,28; 95% ДИ=1,30-8,32; p=0,01) были достоверно больше при ТЭПД.ЗАКЛЮЧЕНИЕ: тоннельный метод подслизистой диссекции является эффективной и безопасной альтернативой классическому методу. Однако, в настоящее время отмечается недостаток данных для решения вопроса о выборе метода подслизистой диссекции при крупных аденомах и ранних формах рака толстой кишки, что требует дальнейших сравнительных исследований.</p></abstract><trans-abstract xml:lang="en"><p>BACKGROUND: endoscopic submucosal dissection (ESD) is a modern effective method for patients with benign epithelial tumors and early colorectal cancer.The use of such a technique for ESD as a submucosal tunnel (‘pocket’) – creation under a tumor creates conditions for improving the surgical specimen qualityand reducingfragmentationrate.Aim: to study the effectiveness and safety of the tunnel method of ESD (TESD) in comparison with classical ESD (CESD) in colorectal adenomas and early colorectal cancer.MATERIALS AND METHODS: literature search and meta-analysis were performed in accordance with the PRISMA recommendations using the PUBMED search system in the Medline electronic database without limiting publication datesin the English language literature. The systematic review included all the studies on comparison of the tunnel and classical ESD methods.RESULTS: the analysis included 4 studies (1,422 patients, 458 in the TESD group and 961 in the CESD group). The groups were comparable in the number of adenomas (OR=1.25; 95% CI=0.87-1.79; p=0.22), adenocarcinomas (OR=0.96; 95% CI=0.49-1.87; p=0.90), in the size of neoplasms (95% CI=-6.26-1.22; p=0.19), and in the presence of submucosal fibrosis (p=0.69). There were no significant differences in intraoperative bleeding rate (OR=1.24; 95% CI=0.53-2.88; p=0.61); however, perforations occurred more often when using CESD (OR= 0.35; 95% CI=0.15-0.83; p=0.02). The CESD took significantly longer time than the TESD (OR=-19.1; 95% CI=33.89-4.45; p=0.01). The frequency of en bloc resections (OR=16.06; 95% CI=4.95-52.11; p&lt;0.0001) and R0-resections (OR=3.28; 95% CI=1.30-8.32; p=0.01) were significantly higher in the TESD. CONCLUSION: the tunnel method of endoscopic submucosal dissection is an effective and safe alternative to the classical method. However, there is currently a lack of data for the choice of submucosal dissection method for large colorectal adenomas and early colorectal cancer, which requires further comparative studies.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>эндоскопическая подслизистая диссекция</kwd><kwd>карманный метод</kwd><kwd>тоннельный метод</kwd></kwd-group><kwd-group xml:lang="en"><kwd>endoscopic submucosal dissection</kwd><kwd>pocket method</kwd><kwd>tunnel method</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">Saito Y, Fukuzawa M, Matsuda T, et al.
