Robotic Surgery for Colorectal Cancer.

Master-slave manipulators (otherwise known as telemanipulators) were introduced into minimally invasive surgery in the 1990s to overcome the limitations of laparoscopic surgery. This led to the development of the first robotic surgical systems which, over the last 10 years, have rapidly gained acceptance among colorectal surgeons. Advantages of robotic surgical systems such as superior instrumentation and field of vision enable precise dissection in confined spaces such as the pelvis, which make it a particularly attractive tool for rectal surgery. The feasibility and safety of robotic rectal surgery is now well established and there is increasing evidence that it might offer superior peri- and postoperative outcomes when compared to laparoscopic rectal surgery. Robotic rectal surgery is easier to learn than laparoscopic surgery and the creation of a structured training program for robotic rectal surgery in Europe has facilitated the learning of this technique in an environment that promotes patient safety and improved patient outcomes through equipment fidelity and operator skill. It is foreseeable that in the near future robotic systems will become part of routine surgical practice in colorectal surgery.
