Brief Summary

There is substantial clinical evidence regarding the safety and efficacy of currently practiced bariatric surgical techniques to improve metabolic control and/or resolve type 2 diabetes (T2DM) in clinically severe obese patients (class 3 obesity). Evidence suggests such procedures have greater effects on insulin secretion and insulin action than that expected from weight loss alone, which has led to the recent claim that such procedures may be useful as a primary treatment for T2DM in the moderately obese population. Concurrently, there have also been substantial advances in the non-surgical medical management of T2DM. As a result, the best treatment algorithm for T2DM patients with class 1 \& 2 obesity is increasingly controversial. This trial investigates the utility of currently practiced and available bariatric surgical procedures as compared with multidisciplinary intensive medical and weight management for the treatment of T2DM with class 1 and 2 obesity.

Outcome Measures

Primary Outcomes (1)

    The primary outcome variable of both parallel trials will be the percent of patients attaining glycemic control (defined as fasting plasma glucose \< 126 mg/dL and HbA1c \< 6.5%) at three years of follow-up.

Gastric Band vs Intensive Diabetes & Weight Management

ACTIVE COMPARATOR

Patients will be randomized to receive either 1) laparoscopic placement of an adjustable gastric band (LAGB) or 2) treatment with an intensive medical and weight management (IMWM) program. LAGB will be placed using the "pars flaccida" technique. The Allergan laparoscopic band "LAP BAND" system will be utilized. LAGB ports will be placed in subcutaneous pockets in the right upper abdomen. The IMWM group will participate in the Weight Achievement and Intensive Treatment (Why WAIT) program, which is a multidisciplinary program for weight control and intensive diabetes management designed by Joslin Diabetes Center. Key aspects include: 1) Intensive and interactive medication adjustments, 2) Structured modified dietary intervention, 3) Graded, balanced, and individualized exercise intervention, 4) Cognitive behavioral intervention and 5) Group education.

RYGB vs Intensive Diabetes & Weight Management

ACTIVE COMPARATOR

Patients will be randomized to receive either 1) Roux-en-Y gastric bypass (RYGB) surgery or 2) treatment with an intensive medical and weight management (IMWM) program. RYGB will be performed using a 75 cm antecolic, ante-gastric Roux limb created with a 50 cm pancreaticobiliary limb. A 15-20 cc gastric pouch will be created lying along the lesser curve of the stomach, with division of the vagal trunks at the lower border of the pouch. The IMWM group will participate in the Weight Achievement and Intensive Treatment (Why WAIT) program, which is a multidisciplinary program for weight control and intensive diabetes management designed by Joslin Diabetes Center. Key aspects include: 1) Intensive and interactive medication adjustments, 2) Structured modified dietary intervention, 3) Graded, balanced, and individualized exercise intervention, 4) Cognitive behavioral intervention and 5) Group education.

Eligibility Criteria

Age21 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Potential participants will be those with T2DM, with a diagnosis of diabetes of at least one year in duration,
  • BMI 30-45 kg/m\^2 for the LAGB compared to intensive medical weight and diabetes management and BMI 30-42 kg/m\^2 for LRYGB compared to intensive medical weight and diabetes management,
  • Age 21-65 years,
  • With a strong desire for substantial weight loss, who are free from active cardiovascular or other diseases that would render them unable to partake in a structured exercise program or to undergo a bariatric surgical procedure, and who are committed to life long medical and nutritional follow up.

You may not qualify if:

Limitations and Caveats

Small sample size limits generalizability. Study performed at a single academic medical center. Duration of diabetes and insulin use, as proxies for β-cell function, were not inclusion or exclusion criteria. Long-term durability of beneficial effects of reducing weight and HbA1c could not be evaluated after 3 years. Newer bariatric surgical procedures, e.g. sleeve gastrectomy, were not studied.
