The TRIABETES - ARMMS-T2D Study: A Randomized Trial to Compare Surgical and Medical Treatments for Type 2 Diabetes
Sponsor: University of Pittsburgh
Summary
This research study is being performed to begin to determine the effectiveness of two dominant bariatric surgery procedures versus an intensive lifestyle intervention to induce weight loss in patients and promote improvements in Type 2 diabetes mellitus (T2DM) in moderately obese patients. T2DM is currently the 6th leading cause of mortality in the United States and is a major cause of kidney failure, blindness, amputations, heart attack, and other vascular and gastro-intestinal dysfunctions. Traditionally, treatments include intensive lifestyle modifications with or without glucose lowering agents. Neither treatment alone, or in combination, results in complete resolution of diabetes and its potential long-term complications. Bariatric surgery has been proven as an effective treatment to accomplish sustained and significant weight loss for those with severe obesity and has been shown to induce long-term remission of T2DM. However, despite enthusiasm for these potential treatment options, it is not clear whether diabetes is influenced by the type of surgery or by the amount of weight lost or if bariatric surgery is more effective than non-surgical weight loss induced by diet and physical activity in T2DM patients with moderate BMIs (30-40kg/m2; Class I and Class II obesity, or approximately 65-95 pounds overweight depending on your height). More well-controlled studies are needed to more completely inform health care decision making and clinical practice in this area. This research study aims to obtain preliminary information regarding the effectiveness of two major types of bariatric surgery, Laparoscopic Roux-en-Y Gastric Bypass and Laparoscopic Adjustable Gastric Banding versus an intensive lifestyle intervention to induce weight loss with diet and increased physical activity.

Interventions
Roux-en-Y Gastric Bypass Surgery
Participants assigned to the Roux-en-Y Gastric Bypass treatment group will undergo a surgical procedure that limit foods intake and causes nutrients malabsorption. The procedure is performed with small incisions or laparoscopically. A small stomach pouch is created, the size of an egg, and the small intestine is connected to the pouch. Some of the stomach and small intestine are consequently bypassed by this anatomic change. Those in this treatment group will begin a gradual diet post surgery and will take life long vitamin supplements.
Laparoscopic Adjustable Gastric Banding
Those assigned to the Laparoscopic Adjustable Gastric Banding study group will undergo a surgical procedure where an adjustable silicone band is placed around the upper stomach to decrease its capacity so that you will feel full sooner. It will assist in weight loss by helping you to limit intake of calories. The band will be placed by using several small incisions and telescopic instruments. A thin tube connects the band to an access port just under the skin that you may be able to feel but you will not be able to see it. This allows the band to be tightened or loosened to decrease or increase your stomach capacity as needed. The surgery will take on average 30-45 minutes.
Lifestyle Weight Loss Intervention
Participants will receive a standard behavior weight control program in an in-person format over a period of 12 months conducted by an experienced team of weight loss counselors. During the initial 6 months of study treatment, will attend weekly in-person individual sessions with a weight loss counselor. During months 7-12, will attend in-person sessions on the 1st and 3rd week of the month and will receive a brief (less than 10 minutes in duration) telephone call on the 2nd and 4th week of the month. Each session will focus on a specific behavioral topic related to weight loss, eating behaviors, or exercise behaviors.
