“…Transanal endoscopic microsurgery (TEM), which was described as an innovation in 1983 by Buess et al [1, 2], can be regarded as the first approach to pure natural orifice transluminal endoscopic surgery (NOTES) and single‐port surgery (SPS) [3, 4]. Despite the advantages of classical TEM and its superiority compared with conventional transanal excision [5, 6], including our own concept [7], some difficulties remain, detaining this technique from widespread adoption. The main reasons are the high costs of investment for the required specific TEM devices [8, 9], the long learning curve due to the demanding and inconvenient technique [10, 11], and the at least temporary fecal incontinence in some patients caused by anal dilatation and insertion of the large metal tube [11, 12].…”
