Brief Summary

Type 2 diabetes mellitus is a chronic disease with severe long-term health consequences. In patients with type 2 diabetes mellitus who are also morbidly obese, an abundance of clinical evidence exists showing that significant clinical improvement in their diabetes occurs following certain types of bariatric, or weight loss, surgical procedures. There is additional data showing that bariatric surgical procedures that bypass the beginning of the small intestine, such as the Roux-en Y gastric bypass, can markedly improve type 2 diabetes even before significant weight loss has occurred. This early effect on type 2 diabetes prior to weight loss suggests that bypassing the beginning of the small intestine in patients who are not morbidly obese may also treat type 2 diabetes. There have been small studies outside the United States that support the concept of treating type 2 diabetes with a surgical procedure that bypasses the beginning of the small intestine without causing significant weight loss; however, data is limited in the United States and a call for comparative studies has been made internationally. The investigators propose to compare, in patients who are not morbidly obese, conventional medical treatment of type 2 diabetes to surgical treatment of type 2 diabetes using a bypass procedure that does not cause significant weight loss, the laparoscopic duodenal exclusion.

Outcome Measures

Primary Outcomes (1)

  • Hemoglobin A1C

    The primary outcome is the difference in hemoglobin A1C between the surgical treatment arm and the conventional medical treatment arm.

    One year

Study Arms (2)

Medical Control Group

ACTIVE COMPARATOR

Control group of patients who will receive conventional medical treatment for type 2 diabetes, along with regular dietary and diabetic education, under the monitoring of the study endocrinologist.

Other: Conventional Medical Treatment

Surgical Treatment Group

EXPERIMENTAL

Experimental group in which patients will undergo the laparoscopic duodenal bypass procedure along with regular dietary and diabetic education, under the monitoring of the study endocrinologist.

Procedure: Laparoscopic duodenal exclusion

Interventions

Laparoscopically-performed Roux-en Y intestinal bypass of the duodenum and proximal jejunum; stomach remains normal size and proximal division performed just distal to pylorus.

Also known as: duodenal exclusion, duodenal bypass
Surgical Treatment Group

Standard of care medical treatment for type 2 diabetes to include medications and dietary management under the monitoring of the study endocrinologist.

Also known as: control arm
Medical Control Group

  • treatment with anticoagulant or antiplatelet medication other than aspirin 81 mg/day
  • end-stage renal disease or on dialysis
  • any other serious concomitant medical condition that, in the opinion of the investigator, would compromise the safety of the patient or compromise the patient's ability to participate in the study
