title: The Effectiveness and Safety of Sleeve Gastrectomy in the Obese Elderly Patients: a Systematic Review and Meta-Analysis.
abstract: This systematic review was performed to compare the effectiveness and safety of SG in the obese elderly patients with the young ones.
  
  
  
  Cohort studies that compared outcomes among old and young patients who had undergone SG were included. Summary odds ratios were estimated using a random effect model.
  
  
  
  Eleven studies were included. Old patients had a worse outcome in percentage of excess weight loss than the young ones (SMD -0.39, 95 % CI -0.55 to -0.24). No significant differences were recorded in resolution of co-morbidities: type 2 diabetes mellitus (OR 1.60, 95 % CI 0.84-3.05), hypertension (OR 1.05, 95 % CI 0.65-1.68), dyslipidemia (OR 1.38, 95 % CI 0.68-2.80), OSAS (OR 0.64, 95 % CI 0.30-1.34), or postoperative complications (OR 0.89, 95 % CI 0.51-1.55) between the elderly and the young who had undergone SG.
  
  
  
  SG was effective for weight loss and resolution of co-morbidities with low complication rate in the obese elderly patients.
