Bariatric or metabolic surgery in septuagenarians was associated with higher odds of 30-day complications (OR 1.55; 95% CI 1.26-1.91; P<0.0001) and mortality compared to younger patients.
Meta-Analysis (n=197,194)
Does primary bariatric or metabolic surgery have acceptable safety and efficacy in septuagenarians compared to younger patients?
Bariatric and metabolic surgery is feasible in septuagenarians but carries a significantly higher short-term risk of morbidity and mortality compared to younger patients.
Odds Ratio: 1.55 (95% CI 1.26–1.91)
p-value: p=<0.0001
BACKGROUND: Increasing life expectancy has expanded the older population of adults living with obesity. Effective and sustainable treatment strategies are essential, due to the significant impact of obesity in the elderly on health care systems. We aimed to determine the safety of metabolic/bariatric surgery in septuagenarians. METHODS: A comprehensive search was conducted across PubMed/MEDLINE, Embase, Cochrane Library, Google Scholar, Scopus, and Web of Science for studies published up to 31 December 2024, using Boolean logic and MeSH terms. Eligible studies involved patients aged ≥70 years undergoing primary bariatric or metabolic surgery that reported on 30-day morbidity and mortality, length of hospital stay, weight loss outcomes (BMI, %TWL, %EWL), and improvements in comorbidities. Two reviewers independently conducted study selection, data extraction, and risk of bias assessment using the ROBINS-I tool, with discrepancies resolved by a third reviewer. Publication bias was assessed via funnel plots and Egger's test. Data were pooled using a random-effects model. RESULTS: Out of 5000 articles, 12 studies met the inclusion criteria, comprising 197,194 patients, including 2528 septuagenarians. Septuagenarians had a mean age of 73.9 ± 2.6 years, and a lower preoperative BMI (42.4 ± 8.0 kg/m 2 ) compared to younger patients (46.0 ± 7.8 kg/m 2 , P < 0.0001). In patients ≥70 years, the pooled 30-day morbidity was 9.0% (95% CI: 6.0-13.0%) and mortality 0.7% (95% CI: 0.0-1.2%). Compared to younger patients, those aged ≥70 years had higher odds of 30-day complications (OR 1.55, 95% CI: 1.26-1.91, P < 0.0001) and mortality (OR 4.31, 95% CI: 1.53-12.11, P = 0.006). No significant differences were found in hospital stay or late complications. Although postoperative BMI was similar, septuagenarians had lower %TWL and %EWL, with comparable improvements in type 2 diabetes and hypertension. CONCLUSIONS: Our findings support the feasibility of metabolic and bariatric surgery in septuagenarians, albeit with a higher short-term risk profile, necessitating careful patient selection and management.
