title: Colorectal surgery in elderly patients: our experience with DaVinci Xi® System.
abstract: BACKGROUND
  Robotic technology for colorectal surgery was introduced by Weber in 2002 to improve the benefits of the minimally invasive surgery already offered by the laparoscopic approach.
  
  
  OBJECTIVE
  To evaluate the feasibility and the efficacy of the application of robotic surgery in elderly patients affected by colorectal diseases.
  
  
  METHODS
  We reported the outcomes obtained during our first 50 colorectal robotic surgical performances with DaVinci Xi® System, and we compared the results assessed for patients younger or older than 70 years.
  
  
  RESULTS
  We examined 28 patients younger and 22 older than 70 years who underwent colorectal robotic surgery in our institution from September 2014 to June 2016. We performed 15 right colectomies, 20 left colectomies, 15 rectal resections. Mean ASA score was significantly higher in the Elderly Group. No statistically significant differences have been revealed in terms of post-operative morbidity, hospital stay, first diet intake, first flatus canalization and oncological outcome.
  
  
  CONCLUSIONS
  According to the prolonged operative time, robotic technology was initially reserved to young patients with good performance status in order to avoid systemic failures in elderly patients suffering from pre-existent comorbidities. Otherwise, once robotic approach safety and benefits in terms of better systemic outcomes were demonstrated, it started to be performed in elderly patients with satisfactory outcomes.
  
  
  CONCLUSIONS
  Our experience revealed that robotic surgical approach is safe, feasible and offers many systemic benefits in elderly patients also with high ASA score. Age alone has not to be considered as exclusion criteria for robotic approach.
