The number of robot-assisted surgeries for rectal cancer has increased in Japan since the insurance coverage of robot-assisted surgery for rectal cancer in 2018. In addition, robot-assisted surgery for colon cancer has not been covered by insurance so far due to a lack of evidence showing its usefulness, but in April 2022, robot-assisted surgery for colon cancer was also be covered by insurance. At the same time, the surgeon requirements for the introduction of robotic surgery have been simplified, so the number of robotic surgeries will increase. Robotic-assisted surgery offers clear three-dimensional high definition images, motion scaling and anti-shake function, and stable forceps manipulation. This compensates for the disadvantages of laparoscopic surgery. Currently, the evidence for robot-assisted colectomy has not been established, but cohort and database studies have reported that robot-assisted colectomy has advantages in terms of open conversion rate, blood loss, and low complication rate. In this article, we summarize the evidence to date for robot-assisted surgery for colon cancer and discuss its future prospects.
