Robotic technology has been applied to colorectal surgery over the last decade. The aim of this review is to analyze the outcomes of robotic colorectal surgery systematically and to provide objective information to surgeons.


Studies were searched and identified using PubMed and Google Scholar from Jan 2001 to Feb 2013 with the search terms "robot," "robotic," "colon," "rectum," "colorectal," and "colectomy." Appropriate data in the studies about the outcomes of robotic colorectal surgery were analyzed.


Sixty-nine publications were included in this review and composed of 39 case series, 29 comparative studies, and 1 randomized controlled trial. Most of the studies reported that robotic surgery showed a longer operation time, less estimated blood loss, shorter length of hospital stay, lower complication and conversion rates, and comparable oncologic outcomes compared to laparoscopic or open surgery.


Robotic colorectal surgery is a safe and feasible option. Robotic surgery showed comparable short-term outcomes compared to laparoscopic surgery or open surgery. However, the long operation time and high cost are the limitations of robotic surgery.
