Is Sleeve Gastrectomy as Effective in Older Patients as in Younger Patients? A Comparative Analysis of Weight Loss, Related Comorbidities, and Medication Requirements.

ABSTRACT

BACKGROUND: Bariatric surgery in the older population has been the subject of ongoing debate but several studies have recently demonstrated its short-term advantages in this age group. It is not yet clear, however, whether these benefits are long-lasting. METHODS: We retrospectively analyzed patients with morbid obesity who underwent laparoscopy sleeve gastrectomy (LSG). These patients were divided into two groups those above 60 years of age (older group) and those of 60 years or under (younger group). Variables evaluated included demographics and anthropometrics data, comorbidities, and daily medication requirements. RESULTS: Two hundred fifty-two patients underwent LSG, 57 in the older group and 195 in the younger group. Outcomes related to weight loss in the older subjects were modest compared to those in the younger population (older group %EWL 41.6 vs younger group %EWL 51.1, p < 0.05, older group %TWL 24.9% vs younger group %TWL 25.2%, p < 0.05). During follow-up, both older and younger patients showed an improvement in all the comorbidities hypertension (older 82.5% vs 38.1%, younger 52.6% vs 29.2%, p < 0.05), type 2 diabetes mellitus (older 38.6% vs 27.3%, 34.9% vs 23.9%, p < 0.05), hyperlipidemia (older 75.4% vs 42.9%, younger 35.9% vs 21.1%, p < 0.05), and OSAHS (older 57.9% vs 30%, younger 40.4% vs 7.1%, p < 0.05). The average number of daily medications used to manage comorbidities decreased in both groups. CONCLUSION: LSG in older patients is effective in terms of weight loss, improvement of comorbidities, and lower daily medication requirements up to 5 years of follow-up.
