“…In this recent study, Keller et al showed that laparoscopic surgery for colorectal cancer in the elderly, in addition to the clinical benefits, reduces overall costs in comparison to open surgery [ 15 ]. Robotic surgery was born to overcome the limits of laparoscopy (2-D vision, reduced ergonomics in confined spaces, tremor effect and unnatural hand–eye coordination) and was successfully applied to urology, general and pediatric surgery, gynaecology, and other surgical fields [ 11 , 12 , 17 , 28 , 29 ]. Robotic surgery has some advantages, such as shorter learning curve, 3-D views, increased wrist flexibility, better ergonomic benefits, reduction of hand tremor and surgeon workloads [ 8 , 11 , 12 , 16 , 17 , 30 ].…”
