    Abstract:
    BACKGROUND: Bariatric surgery is the most effective treatment of obesity. There are few studies evaluating long-term outcomes in elderly patients. OBJECTIVES: Our study was designed to evaluate the safety and long-term outcomes of bariatric surgery in the elderly compared with a contemporary medically managed cohort. SETTING: University hospital. METHODS: Three hundred thirty-seven patients age ≥60 who underwent a sleeve gastrectomy or Roux-en-Y gastric bypass between January 2007 and April 2017 were identified (ElderSurg) and compared with a matched cohort of medically managed elderly patients with obesity (ElderNonSurg). RESULTS: Thirty-two patients underwent laparoscopic sleeve gastrectomy, 190 underwent laparoscopic Roux-en-Y gastric bypass, and 115 underwent open Roux-en-Y gastric bypass. The cohort was a mean of 64.4-years old, 75.4% female, mean preoperative body mass index was 46.9, and 62.6% had type 2 diabetes. During a median follow-up period of 56.2 months (confidence interval 49.5-62.9), mean percent excess weight loss (EWL) at nadir was 72.1 ± 24.7% and EWL at 36 months or beyond was 60.9 ± 27.6%. On regression analysis, diabetes, body mass index, and laparoscopic sleeve gastrectomy were negatively associated with EWL at all time periods (P < .05). Mean %EWL was greater for Roux-en-Y gastric bypass compared with laparoscopic sleeve gastrectomy (61.7 versus 41.2; P = .039). Diabetes remission rate was 45.8%. There was a statistically significant decrease in the risk of death in ElderSurg (hazard ratio .584, 95% confidence interval .362-.941) compared with ElderNonSurg. CONCLUSIONS: Our study supports that bariatric surgery is safe in elderly patients with effective long-term control of obesity, diabetes, and with improved overall survival.
