Transanal Excision

The transanal excision technique has evolved significantly over the past 30 years. In 1983, Gerhard Buess introduced a disruptive technique into colorectal surgery, transanal endoscopic microsurgery (TEM) [1, 2]. Compared with transanal excision (TAE), TEM was associated with a superior quality of resection, demonstrated by higher rates of negative margins and lower rates of local recurrence [3–10].
