Safety of robotic general surgery in elderly patients.

Abstract

As the life expectancy of people in Western countries continues to rise, so too does the number of elderly patients. In parallel, robotic surgery continues to gain increasing acceptance, allowing for more complex operations to be performed by minimally invasive approach and extending indications for surgery to this population. The aim of this study is to assess the safety of robotic general surgery in patients 70years and older. From April 2007 to December 2009, patients 70years and older, who underwent various robotic procedures at our institution, were stratified into three categories of surgical complexity (low, intermediate, and high). There were 73 patients, including 39 women (53.4%) and 34 men (46.6%). The median age was 75years (range 70-88years). There were 7, 24, and 42 patients included, respectively, in the low, intermediate, and high surgical complexity categories. Approximately 50% of patients underwent hepatic and pancreatic resections. There was no statistically significant difference between the three groups in terms of morbidity, mortality, readmission or transfusion. Mean overall operative time was 254±133min (range 15-560min). Perioperative mortality and morbidity was 1.4% and 15.1%, respectively. Transfusion rate was 9.6%, and median length of stay was 6days (range 0-30days). Robotic surgery can be performed safely in the elderly population with low mortality, acceptable morbidity, and short hospital stay. Age should not be considered as a contraindication to robotic surgery even for advanced procedures.
