Abstract Aim Laparoscopic rectal surgery is associated with a steep learning curve and high conversion rate despite progress in equipment design and consistent practice. The robotic system has shown an advantage over the laparoscopic approach due to stable three-dimensional views, improved dexterity and better ergonomics. These factors make the robotic approach more favourable for rectal surgery. The aim of this study was to compare the perioperative outcomes of laparoscopic and robotic rectal cancer surgery in high-risk patients. Method A prospectively collected dataset for high-risk patients who underwent rectal cancer surgery between May 2013 and November 2015 was analysed. Patients with any of the following characteristics were defined as high risk: a body mass index ≥30, male gender, preoperative chemoradiotherapy, tumour
