title: Roux-en-Y Gastric Bypass in the Elderly: a Systematic Review.
abstract: The prevalence of severe obesity in the elderly is increasing. This systematic review reviews the literature in reference to the efficacy and safety of bariatric surgery on the elderly patient ≥ 65 years. A comprehensive search of electronic databases was completed. The data was limited to include only Roux-en-Y gastric bypass patients ≥ 65 years. Eight primary studies (1835 patients) were included, all case series. Mean age was 67.6 years. Mean excess weight loss at study endpoint was 66.2 %. Mean 30-day mortality was 0.14 %. The mean total post-operative complication rate was 21.1 %, with wound infections being the most common (7.58 %) followed by cardiorespiratory complications (2.96 %). Bariatric surgery is effective in producing marked weight loss in patients ≥ 65 years with an acceptable safety profile.
