Medium to long-term outcomes of bariatric surgery in older adults with super obesity.
BACKGROUND
Indications and outcomes of bariatric surgery in older adults suffering from morbid obesity remain controversial. We aimed to evaluate safety and medium to long-term outcomes of bariatric procedures in this patient population.


SETTING
University Hospital, Canada.


METHODS
This is a single-center retrospective study of a prospectively collected database. We included patients aged ≥60 years who underwent sleeve gastrectomy, Roux-en-Y gastric bypass, or biliopancreatic diversion with duodenal switch between January 2006 and December 2014 and had at least 2 years of follow-up.


RESULTS
Of patients, 115 underwent bariatric surgeries (11 patients had 2 procedures). There were 66 were super-obese patients (body mass index>50 kg/m2). Of patients, 74% had sleeve gastrectomy, 16% Roux-en-Y gastric bypass, and 8% underwent biliopancreatic diversion with duodenal switch. Mean age and body mass index were 63.3 ± 2.6 years and 51.7 ± 8.1 kg/m2, respectively. Average follow-up time was 42 ± 19 months. At baseline, 78% had hypertension, 60% had type 2 diabetes, and 30% had obstructive sleep apnea. There was no 30-day mortality. Complication rate was 14% (n = 16): 2 leaks post-Roux-en-Y gastric bypass, 1 leak post-biliopancreatic diversion with duodenal switch, 1 obstruction post-sleeve gastrectomy, 1 bleeding requiring transfusion, 1 liver injury with bile leak, 2 port-site hernias, 1 myocardial infarction, 2 gastrojejunal strictures, 1 wound infection, 1 urinary tract infection, and 3 gastric reflux exacerbations. Mean percent excess weight loss at 2 years was 52.2 ± 23.8. Remission rates of hypertension, type-2 diabetes, and obstructive sleep apnea were 26%, 44%, and 38%, respectively.


CONCLUSION
Bariatric surgery is safe and effective in improving obesity-related co-morbidities in older patients suffering from morbid obesity. Age alone should not preclude older patients from getting the best bariatric procedure for obesity and related co-morbidities.
