Transanal Total Mesorectal Excision (ta-TME)

There is no controversy regarding the surgical treatment of rectal cancer following the cancer criteria proposed by Heald for total mesorectal excision. When it comes to the approach, laparoscopically or conventionally, studies such as COLOR II did not observe differences between both approaches in terms of morbidity, mortality or positivity of the circumferential margin. Robotic approach also seems to be safe. However, prospective trials have not yet demonstrated any advantage compared with a laparoscopic approach.
