Bariatric surgery in elderly patients: a systematic review

Salvatore Giordano et al. Clin Interv Aging. .

Abstract

Controversy exists regarding the effectiveness and safety of bariatric/metabolic surgery in elderly patients. We performed a systematic review on this issue in patients aged 60 years or older. MEDLINE, Cochrane Library, Embase, Scopus, and Google Scholar were searched until August 2015 for studies on outcomes of bariatric surgery in elderly patients. The results were expressed as pooled proportions (%) with 95% confidence intervals. Heterogeneity across the studies was evaluated by the I (2) test, and a random-effects model was used. Twenty-six articles encompassing 8,149 patients were pertinent with this issue and included data on bariatric surgery outcomes in elderly population. Fourteen patients died during the 30-day postoperative period, with a pooled mortality of 0.01%. Pooled overall complication rate was 14.7%. At 1-year follow-up, pooled mean excess weight loss was 53.77%, pooled diabetes resolution was 54.5%, and pooled hypertension resolution was 42.5%, while pooled lipid disorder resolution was 41.2%. Outcomes and complication rates of bariatric surgery in patients older than 60 years are comparable to those in a younger population, independent of the type of procedure performed. Patients should not be denied bariatric surgery because of their age alone.

Keywords: bariatric surgery; elderly; gastric bypass; laparoscopy; morbid obesity; weight loss.
