title: Laparoscopic Roux-en-Y gastric bypass in the elderly: feasibility, short-term safety, and impact on comorbidity and weight in 250 cases.
abstract: BACKGROUND
  In the elderly obese population, frequently suffering from multiple comorbidities, laparoscopic Roux-en-Y gastric bypass (LRYGB) is considered a high-risk procedure. The aim of this study was to evaluate short-term safety (30-day hospital morbidity and mortality) of this procedure and its impact on weight and associated comorbidities in the medium term (type-two diabetes, hypertension, sleep apnea, hypercholesterolemia, and joint pain).
  
  
  METHODS
  This study represents a retrospective analysis of all our Belgian patients older than 60 years of age who underwent a LRYGB between October 2004 and October 2012. Patient files were reviewed and patients were contacted by formal consultation or by phone for an update of their clinical status. Demographics, operative details, postoperative course, and the evolution of weight and associated comorbidities were registered.
  
  
  RESULTS
  A total of 280 patients were included. A complete follow-up was available for 250 patients (89 %), of whom 161 were female and 89 male. Mean age, BMI, and hospital stay were 64.1 years (60-78 years), 41.9 kg/m(2) (27.4-68 kg/m(2)), and 4.3 days (2-19 days), respectively. There was no in-hospital mortality, 27 (10.8 %) patients suffered from early postoperative complications and 5 (2 %) patients needed to be readmitted. After a mean follow-up of 31.5 months, the mean excess weight loss was 59.3 % (range 21.9-120.1 %). Resolution or improvement of diabetes, hypertension, sleep apnea, hypercholesterolemia, and joint pain was seen in 94.6, 77.6, 88.0, 77.1 and 57.6 % respectively.
  
  
  CONCLUSIONS
  LRYGB has an acceptable complication rate in the elderly. Since all obesity-related comorbidities improved during follow-up, there is a plea not to exclude this subgroup of patients from the well-known benefits of gastric bypass surgery.
