Bariatric surgery outcomes: is age just a number?

Area of Science:

• Bariatric Surgery Outcomes
• Obesity Management
• Geriatric Surgery

Background:

• Obesity and its comorbidities are a significant public health issue across all age groups in the US.
• Conflicting data exist regarding the efficacy and recovery of bariatric surgery in elderly populations.
• This study aims to compare bariatric surgery outcomes across different age demographics.

Purpose of the Study:

• To compare the safety and effectiveness of bariatric surgery in various age groups.
• To analyze postoperative recovery, weight loss, and comorbidity resolution by age.
• To inform clinical decisions regarding bariatric surgery for different patient age demographics.

Main Methods:

• Retrospective study of 1026 patients undergoing laparoscopic Roux-en-Y gastric bypass (LRYGB) or sleeve gastrectomy (LSG) between 2011-2015.
• Patients were stratified into five age groups: <30, 30-39, 40-49, 50-59, and ≥60 years.
• Outcomes analyzed included BMI change (ΔBMI), reoperations, readmissions, mortality, and comorbidity resolution, compared using statistical tests.

Main Results:

• Older patients (≥60 years) had lower preoperative BMI than younger groups (<50 years).
• Patients aged 50-59 experienced longer hospital stays; older patients had a higher prevalence of comorbidities.
• No significant differences were observed in 30-day readmissions, 90-day mortality, or reintervention rates across age groups. Younger patients showed greater ΔBMI and comorbidity resolution, except for obstructive sleep apnea.

Conclusions:

• Bariatric surgery is safe and effective for weight loss across all age groups.
• Older patients face longer hospital stays and reduced comorbidity resolution compared to younger individuals.
• Offering bariatric surgery earlier in life is recommended to maximize patient benefits.
