Background:
Colorectal cancer is the third most common cancer worldwide. Current treatment approaches are multidisciplinary, including neoadjuvant chemoradiotherapy for rectal cancer. Several studies have reported an improvement in surgical techniques and in new devices facilitating better pre- and intraoperative staging.
Objectives:
Since its first application in 2002, robotic surgery has progressed steadily, offering good surgical results and better oncological outcomes. Currently, many studies and reviews have confirmed its safety and feasibility for colorectal cancer.
Materials And Methods:
Robotic technology simplifies surgical maneuvers thanks to the three-dimensional magnification and stable vision, convenient mobility of the robotic arms, endowrist instruments with seven degrees of freedom, ambidextrous capability, tremor filtering, and indocyanine green fluorescence imaging.
Results:
Regarding the oncological outcome, the robotic technique is equivalent to the laparoscopic approach; however, a lower recurrence rate has been achieved with the robotic approach in extended lymphadenectomy as part of complete mesocolic excision for right colonic cancer and total mesorectal excision for low rectal tumors.
Conclusion:
Colorectal robotic surgery has progressively improved worldwide. Its advantages are related not only to better oncological outcomes, but also to improvements in terms of detection, accurate diagnosis, and staging.
