A call to define the targets of robotic surgery

We read with great interest the article “Robot-assisted laparoscopic resection of clinical T4b tumours of distal sigmoid and rectum: initial results” by Crolla et al. (1), and we look with enthusiasm at the authors’ results. As they assessed, nowadays robot-assisted surgery has clear advantages in terms of view and range of motion of instruments, even more in T4 tumors in which it allows an easily approach to a narrow pelvis with a bulky lesion.
