The main group included 50 patients who underwentendoscopic submucosal tunnel dissection. The control group included 50 patients who underwent traditional endo-scopic submucosal dissection (ESD).   Results: Four (4 %) patients (1 in the main and 3 in the control group) were excluded from the study due to theconversion of endoscopic procedure. The incidence en bloc removal of neoplasms and the negative resection margins were significantly higher in the main group than in the control one — 98 % and 87.2 % (p = 0.04) and 89.8 % and 70.2 %, respectively (p = 0.01).   Conclusion: ESTD for large benign epithelial colon neoplasms shows better radicalness in comparison with endo-scopic submucosal dissection.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>эндоскопическая подслизистая диссекция</kwd><kwd>доброкачественные новообразования</kwd><kwd>толстая кишка</kwd><kwd>тоннельный метод</kwd><kwd>ESTD</kwd><kwd>ESD</kwd></kwd-group><kwd-group xml:lang="en"><kwd>endoscopic submucosal dissection</kwd><kwd>benign colon neoplasms</kwd><kwd>tunnel method</kwd><kwd>ESTD</kwd><kwd>ESD</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы не имеют финансовых или имущественных интересов в материале, обсуждаемом в этой статье</funding-statement><funding-statement xml:lang="en">The authors have no financial or proprietary interests in the material discussed in this article</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Doniec J.
