- Surgical options in type 2 diabetes(2015) PAJECKI, D.; RICCIOPPO, D.; KAWAMOTO, F.; SANTO, M. A.The onset of type 2 diabetes is characterized by a nonreversible complex cycle that includes severe deleterious effects on glucose metabolism. Obesity, but mainly visceral adipose tissue accumulation, is an important factor in this process. The goals of diabetes management in clinical practice, despite the improvement over the years, are often not met. In the last 20 years, based on observations of bariatric surgery series that have shown great improvement of type 2 Diabetes in morbid obese patients, metabolic surgery has emerged as a therapeutic possibility. In 2011 the International Diabetes Federation released its position statement mentioning that bariatric surgery was an accepted option for T2DM patients with BMI > 35 kg/m2 and might be considered an alternative therapy for patients with BMI ≤ 35 kg/m2 who do not respond to standard medical therapy. Metabolic/bariatric surgery includes the application of conventional bariatric procedures (Roux-en-Y gastric bypass, biliopancreatic diversion, sleeve gastrectomy) and the introduction of new procedures (ileal interposition, intestinal bipartition) designed with the specific aim of having metabolic effects, irrespective of causing massive weight loss. The reversal of T2DM occurs due to mechanisms such as the increase in insulin sensitivity associated with an improvement in beta-cell function, including recovering the first phase of insulin secretion. This recovery is a consequence of the increase of GLP-1 production, and change in circulating bile acids. Remission of diabetes is observed on the first postoperative days after the operation. © Springer International Publishing Switzerland 2015.

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.
