Primary Endpoints
• After two years (93% follow up)
• No patient on medical therapy achieved remission
• Rates of complete remission of diabetes (FBG </=100mg/dl, HGA1c </=6.0% for at least one year without medications)
• CR 75% Gastric Bypass and 95% for BPD
• Surgical procedures achieved diabetes control independent of preoperative BMI and post operative weight loss
