Abstract
Despite the growth in laparoscopic surgery, comparable oncological outcomes, and reduced complication rates, the majority of colorectal surgery is still performed via an open approach. Reasons for this may include technical difficulties associated with operating in narrow spaces such as in the pelvis and inadequate experience. Robotic surgery provides potential solutions to some of these challenges. This review will summarize the state of the literature regarding robotic colorectal surgery. The most consistent benefit of robotic surgery is decreasing operative conversions, specifically in rectal cancer. In partial colectomies, there is evidence to support quicker return to bowel function. Oncologic outcomes compared to the laparoscopic approach are equivalent. Robotic surgery provides solutions to the challenges posed by laparoscopy, including wristed instruments, ease of intracorporeal suturing, and ergonomic advantages. Randomized trials to evaluate peri-operative outcomes will be important. If robotics is able to facilitate conversion of open colectomies to their minimally invasive equivalent, robotics may end up proving to be advantageous in the peri-operative and post-operative period. Continued studies are warranted.
