Background: Surgical treatment of obesity in the elderly, particularly over 65, remains
controversial; it is explained by the increased surgical risk or the lack of data
demonstrating its long-term benefit. Few studies have evaluated the clinical
effects of bariatric surgery in this population. Aim: To evaluate the results of surgical treatment of obesity in patients over 60
years, followed for an average period of five years. Method: This was a retrospective study evaluating 46 patients, 60 years or older, who
underwent surgical treatment of obesity, by conventional gastric bypass technique
(laparotomy). The average age was 64 years (60-71), mean BMI of 49.6
kg/m2 (38-66), mean follow-up of 5.9 years; 91% of patients were
hypertensive, 56% diabetics and 39% had dyslipidemia. Results: The incidence of complications (major and minor) in patients under 65 years was
26% and over 65 years 37% (p=0.002). There were no deaths in the group with less
than 65 years and there were two deaths (12.5%) over 65 years. The average loss of
overweight over 65 years or less was 72% vs 68% (p=0.56). There was total control
of the diabetes mellitus in 77% and partial in 23%, with no difference between
groups. There was improvement in arterial hypertension in 56% of patients, also no
difference between groups. The average LDL levels did not differ between the pre
and postoperative (106 mg/dl to 102 mg/dl), an increase of HDL (56 mg/dl to 68
mg/dL) and reduced triglyceride levels (136 mg/dl to 109 mg/dl). There was no
statistical difference in the variation of the cholesterol fractions and
triglycerides between the groups. Two patients in the group with less than 65
years died in late follow-up, of brain tumor and pneumonia, three and five years
after bariatric surgery, respectively. Conclusions: Surgical morbidity and mortality were higher in patients over 65 years, and this
group had the same benefits observed in patients lower 65 years for weight loss
and comorbidities control.
