Both European Society of Gastrointestinal Endoscopy (ESGE) and American guidelines suggest resection of small rectal neuroendocrine tumors (NETs) by endoscopic submucosal dissection (ESD) for lesions up to 20mm [1, 2]. A completely resected rectal NET (R0) with no pejorative factors for recurrence (< 10mm, T1, grade 1, no lymphovascular invasion) requires no additional exploration and no follow-up [3]. Obtaining healthy horizontal margins is easy, but it is sometimes more difficult to obtain free vertical margins above the point of deepest submucosal invasion. For this, it is necessary to perform a deep submucosal dissection, sliding along the muscular layer; strong and adaptive traction seems to us to be very useful to facilE-Videos
