STUDY OBJECTIVE
• To evaluate the effects of two bariatric procedures versus intensive medical therapy (IMT) on β-cell function and body composition

STUDY DESIGN AND METHODS
• Prospective, randomized, controlled trial of 60 subjects with uncontrolled type 2 diabetes and moderate obesity, randomized to IMT alone, IMT plus Roux-en-Y gastric bypass, or IMT plus sleeve gastrectomy
• Assessment of β-cell function (mixed-meal tolerance testing) and body composition was performed at baseline and 12 and 24 months

RESULTS
• Glycemic control improved in all three groups at 24 months
• Reduction in body fat was similar for both surgery groups, with greater absolute reduction in truncal fat in gastric bypass versus sleeve gastrectomy
• Insulin sensitivity increased significantly from baseline in gastric bypass and did not change in sleeve gastrectomy or IMT
• β-Cell function increased 5.8-fold in gastric bypass from baseline, was markedly greater than IMT, and was not different between sleeve gastrectomy versus IMT
• At 24 months, β-cell function inversely correlated with truncal fat and prandial free fatty acid levels

CONCLUSIONS
• Bariatric surgery provides durable glycemic control compared with intensive medical therapy at 2 years
• Despite similar weight loss as sleeve gastrectomy, gastric bypass restores pancreatic β-cell function and reduces truncal fat
