Robotic transanal total mesorectal excision: A new perspective for low rectal cancer treatment. A case series

Rectal cancer treatment is still a challenging frontier in general surgery, as there is no general agreement on which surgical approach is best for its management. Total mesorectal excision (TME), influenced the practical approach to rectal cancer, and brought a significant improvement on tumor recurrence and patients survival. Robotic transanal surgery is a newer approach to rectal dissection whose purpose is to overcome the limits of the traditional transabdominal approach, improving accuracy of distal dissection and preservation of hypogastric innervation. An increasing interest on this new technique has raised, thanks to the excellent pathological and acceptable short-term clinical outcomes reported.

Three consecutive cases of robotic transanal TME were prospectically performed between May 2017 and October 2017.

TME quality was Quirke 3 grade in all cases. Mean operative time was 530 min. None of the patients had intra-operatively or post-operatively complications.

Robotic transanal TME is a very recent procedure. Acclaimed greatest advantage of robotic transanal TME is the facilitation of dissection with an in-line view, which translates in an improved surgical field exposure and visualization. Further investigations are needed to assure the actual value of robotic transanal approach.
