Surgical vs medical treatments for type 2 diabetes mellitus: a randomized clinical trial.
IMPORTANCE Many questions remain unanswered about the role of bariatric surgery for people with type 2 diabetes mellitus ( T2DM ) . OBJECTIVE To determine feasibility of a r and omized clinical trial ( RCT ) and compare initial outcomes of bariatric surgery and a structured weight loss program for treating T2DM in participants with grade s I and II obesity . DESIGN , SETTING , AND PARTICIPANTS A 12-month , 3-arm RCT at a single center including 69 participants aged 25 to 55 years with a body mass index ( calculated as weight in kilograms divided by height in meters squared ) of 30 to 40 and T2DM . INTERVENTIONS Roux-en-Y gastric bypass ( RYGB ) , laparoscopic adjustable gastric b and ing ( LAGB ) , and an intensive lifestyle weight loss intervention ( LWLI ) . MAIN OUTCOMES AND MEASURES Primary outcomes in the intention-to-treat cohort were feasibility and effectiveness measured by weight loss and improvements in glycemic control . RESULTS Of 667 potential participants who underwent screening , 69 ( 10.3 % ) were r and omized . Among the r and omized participants , 30 ( 43 % ) had grade I obesity , and 56 ( 81 % ) were women . Mean ( SD ) age was 47.3 ( 6.4 ) years and hemoglobin A1c level , 7.9 % ( 2.0 % ) . After r and omization , 7 participants ( 10 % ) refused to undergo their allocated intervention ( 3 RYGB , 1 LAGB , and 3 LWLI ) , and 1 RYGB participant was excluded for current smoking . Twenty participants underwent RYGB ; 21 , LAGB ; and 20 , LWLI , with 12-month retention rates of 90 % , 86 % , and 70 % , respectively . In the intention-to-treat cohort with multiple imputation for missing data , RYGB participants had the greatest mean weight loss from baseline ( 27.0 % ; 95 % CI , 30.8 - 23.3 ) compared with LAGB ( 17.3 % ; 95 % CI , 21.1 - 13.5 ) and LWLI ( 10.2 % ; 95 % CI , 14.8 - 5.61 ) ( P < .001 ) . Partial and complete remission of T2DM were 50 % and 17 % , respectively , in the RYGB group and 27 % and 23 % , respectively , in the LAGB group ( P < .001 and P = .047 between groups for partial and complete remission ) , with no remission in the LWLI group . Significant reductions in use of antidiabetics occurred in both surgical groups . No deaths were noted . The 3 serious adverse events included 1 ulcer treated medically in the RYGB group and 2 rehospitalizations for dehydration in the LAGB group . CONCLUSIONS AND RELEVANCE This study highlights several potential challenges to successful completion of a larger RCT for treatment of T2DM and obesity in patients with a body mass index of 30 to 40 , including the difficulties associated with recruiting and r and omizing patients to surgical vs nonsurgical interventions . Preliminary results show that RYGB was the most effective treatment , followed by LAGB for weight loss and T2DM outcomes at 1 year . TRIAL REGISTRATION clinical trials.gov Identifier : NCT01047735
