Endoscopic submucosal dissection for cecal adenomas had technical limitations due to the adjacent ileocecal valve and appendix opening, perpendicular operating angle. Case presentation of the possibility of successful removal of a large laterally spreading cecal adenoma by the method of endoscopic submucosal tunnel dissection (ESTD) never been described before for this tumor site and size. Patient 54 years old, an LST-G adenoma (5 cm in diameter, according to Kudo – IIIL, according to Sano – II) was detected in the dome of the cecum during colonoscopy. ESTD. The postoperative period without any unfavorable events; the patient was discharged on the 5th day after surgery. The morphological conclusion: tubulo-villous adenoma with moderate epithelial dysplasia, R0. ESTD is suitable for cecal giant adenomas.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>аденома</kwd><kwd>тоннельный метод</kwd><kwd>подслизистая диссекция</kwd><kwd>слепая кишка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>adenoma</kwd><kwd>tunnel method</kwd><kwd>the submucosal dissection</kwd><kwd>the cecum</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">Miura Y, Shinozaki S, Hayashi Y. et al.
