[Robotic rectal surgery]

Colorectal cancer is one of the most frequent cancerous diseases in industrial nations, whereby tumors of the rectum constitute approximately 30-40% of all colorectal cancers. In addition to the implementation and establishment of novel neoadjuvant concepts for the treatment of rectal cancer, there has been a continuous evolution of surgical techniques in recent years towards minimally invasive surgery. In this respect robot-assisted surgery has become more and more popular despite seemingly weak evidence regarding clinical benefits and the not to be ignored economic aspects; however, recently published high-quality studies provide new evidence showing advantages for a robotic resection in patients suffering from rectal cancer. Thus, the progressive implementation of robotic surgical systems is increasingly attaining a scientific foundation.
