Abstract
BACKGROUND: An increasing number of older patients undergo bariatric surgery. OBJECTIVE: To define the risk for complications and mortality in relation to age after gastric bypass. SETTING: A national registry-based study. METHODS: Patients (n = 47,660) undergoing gastric bypass between May 2007 and October 2016 and registered in the Scandinavian Obesity Register were included. Risk between age groups was compared by multivariate analysis. RESULTS: The 30-day follow-up rate was 98.1%. In the entire cohort of patients, any complication within 30 days was demonstrated in 8.4%. For patients aged 50 to 54, 55 to 59, and ≥60 years, this risk was significantly increased to 9.8%, 10.0%, and 10.2%, respectively. Rates of specific surgical complications, such as anastomotic leak, bleeding, and deep infections/abscesses were all significantly increased by 14% to 41% in patients aged 50 to 54 years, with a small additional, albeit not significant, increase in risk in patients of older age. The risk of medical complications (thromboembolic events, cardiovascular, and pulmonary complications) was significantly increased in patients aged ≥60 years. Mortality was .03% in all patients without differences between groups. CONCLUSIONS: In this large data set, rates of complications and mortality after 30 days were low. For many complications, an increased risk was encountered in patients aged ≥50 years. However, rates of complications and mortality were still acceptably low in these age groups. Taking the expected benefits in terms of weight loss and improvements of co-morbidities into consideration, our findings suggest that patients of older age should be considered for surgery after thorough individual risk assessment rather than denied bariatric surgery based solely on a predefined chronologic age limit.
