Abstract
After their first introduction in the 1990s to overcome the limitations of conventional laparoscopic surgery, especially in confined spaces such as the pelvis, telemanipulators (i.e., master-slave manipulators) have gained popularity and acceptance among gastrointestinal surgeons. These complex, interventional surgical devices use multiple technologies, such as 3-D advanced imaging, tremor reduction and 7-degree movement. Superior instrument dexterity, stable precise vision and accessibility to narrow confined spaces make these devices well suited for colorectal surgery. The drive for innovations in the field of surgical robotics will leverage novel robots driven by data, image integration, and artificial intelligence. However, if this vision is to be realized, lessons must be learned from the current literature and clinical trials. The feasibility and safety of robotic rectal surgery is now well established; increasing evidence suggests that when compared to laparoscopic rectal surgery, robotic approaches might offer superior peri-operative outcomes. Notably, the marginal gains achieved with the use of robotics in rectal cancer surgery are linked with structured training and standardization of operative techniques. With decreasing costs and wider availability of new systems, it is foreseeable that robotic surgical systems will be an integral part of colorectal practice.
