Conclusions Conclusions
Robot-assisted rectal resection are feasible and safe.
The robotic technique may improve TME, nerves sparing and
intersphynteric dissection in ultralow rectal resection.
Major advantages can be appreciated in males, in narrow and
deep pelvis, and in obese patients.
The long-term functional and oncological results are very
interesting.
We are waiting the ROLARR trial.
