title: Robotic revisional bariatric surgery: single-surgeon case series.
abstract: BACKGROUND
  Bariatric surgery is the only effective treatment for the long-term maintenance of significant weight loss. Minimally invasive revisional procedures are on the rise. Data is lacking in terms of safety, feasibility and outcomes with robotic revisional procedures.
  
  
  METHODS
  Robotic revisional bariatric procedures (RRBPs) of gastric band to Roux-en-Y gastric bypass and sleeve gastrectomy, revision of gastro-jejunal anastomosis and stricturoplasty performed during 2009-2013 were retrospectively reviewed.
  
  
  RESULTS
  RRBPs were performed on 14 patients with mean age, pre-operative body mass index (BMI) and weight of 45.2 ± 11.4 years, 40.1 ± 8.7 kg/m2and 109.4 ± 26 kg, respectively. The mean operative time, estimated blood loss and length of hospital stay were 220.6 ± 64.3) min, 31 ± 22.7 ml and 3.3 ± 1.5 days, respectively. There were no conversions, blood transfusions, gastrointestinal leaks, intraoperative complications or mortalities.
  
  
  CONCLUSIONS
  RRBP can be performed safely without increased morbidity and with the added benefit of a minimally invasive approach. Copyright © 2014 John Wiley & Sons, Ltd.
