In a study of obese patients with type 2 diabetes, bariatric surgery was found to be more effective than medical treatment in the long-term control of the disease (for at least 5 years). The study consisted of 60 patients randomized to either medical treatment or surgery (Roux-en-Y gastric bypass or biliopancreatic diversion). The primary endpoint was the rate of diabetes remission at 2 years (defined as HbA1c of 6.5% or less and a fasting glucose concentration of 5.6 mmol/L or less) without active pharmacologic treatment for 1 year. Patients were followed up for 5 years. Among 38 patients who underwent surgery, 19 (50%) maintained diabetes remission at 5 years compared with none of the 15 medically treated patients. The study authors advise continued monitoring of glycemic control because of a potential relapse for hyperglycemia.
