Core tip: Robotic surgery for rectal cancer is a promising approach since it allows a better view of the pelvic cavity and enhanced freedom of instrument movements when compared to conventional laparoscopy. This would potentially translate into a better oncological dissection, and reduced risk of injury to neurovascular structures. This review of the literature shows that no definite conclusion of the potential benefits of robotic surgery can be drawn, and that larger prospective studies with long-term follow up are needed to establish the role of the procedure.
