Abstract
Background: The burgeoning problem of obesity is seen most profoundly in older populations. Despite the dramatic increase in bariatric surgery rates over the last 20 years, weight reduction surgery is largely restricted to younger patients. Methods: This retrospective, longitudinal, self-matched, population-based cohort study assessed the incidence and outcomes of all patients undergoing bariatric surgery who were ≥55 years old in Western Australia between 2007 and 2011. The mean preoperative and post-operative follow-up periods were 2.5 years and 3.4 years, respectively. Results: Of the 12062 bariatric surgical operations recorded during the study period, 2179 (18.1%) were performed in patients aged ≥55 years old. Older bariatric patients were statistically more likely to require longer hospital admissions (2.85 versus 2.65 days, P < 0.001), have post-operative complications (12.0 versus 6.3%, P < 0.001) and require intensive care admissions (8.2 versus 4.3%, P = 0.001) compared to patients <55 years old. However, both 30-day (no deaths in the older cohort) and long-term mortality rates (1.07 versus 0.42 deaths per 1000 patient-years, P = 0.10) remained relatively low. All-cause long-term hospitalization rates were also significantly reduced (P < 0.001) after bariatric surgery for patients who were older than 55 years compared to before surgery. Conclusion: Despite older age being associated with a higher risk of complications and longer hospital stays, there was a reduction in subsequent overall hospitalizations for older patients after bariatric surgery, suggesting that bariatric surgery may still confer health benefits to carefully selected obese older patients who cannot achieve weight loss by other means.
