The Effectiveness and Safety of Sleeve Gastrectomy in the Obese Elderly Patients: a Systematic Review and Meta-Analysis

Abstract

Background: This systematic review was performed to compare the effectiveness and safety of SG in the obese elderly patients with the young ones. Methods: 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. Results: 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. Conclusions: SG was effective for weight loss and resolution of co-morbidities with low complication rate in the obese elderly patients.
