title: Can Sleeve Gastrectomy "Cure" Diabetes? Long-term Metabolic Effects of Sleeve Gastrectomy in Patients With Type 2 Diabetes.
abstract: The aim of the study was to assess long-term metabolic effects of laparoscopic sleeve gastrectomy (LSG) in patients with type 2 diabetes (T2DM) and to identify predictive factors for long-term diabetes remission and relapse.
  
  
  
  LSG has become the most common bariatric operation worldwide. Its long-term metabolic effects in patients with T2DM are, however, unknown.
  
  
  
  Outcomes of 134 patients with obesity with T2DM who underwent LSG at an academic center during 2005 to 2010 and had at least 5 years of follow-up were assessed.
  
  
  
  At a median postsurgical follow-up of 6 years (range: 5-9), a mean body mass index loss of -7.8 ± 5.1 kg/m (total weight loss: 16.8% ± 9.7%) was associated with a reduction in mean glycated hemoglobin (HbA1c, -1.3 ± 1.8%, P < 0.001), fasting blood glucose (-37.8 ± 70.4 mg/dL, P < 0.001) and median number of diabetes medications (-1, P < 0.001). Long-term glycemic control (HbA1c <7%) was seen in 63% of patients (vs 31% at baseline, P < 0.001), diabetes remission (HbA1c <6.5% off medications) in 26%, complete remission (HbA1c <6% off medications) in 11%, and "cure" (continuous complete remission for ≥5 years) was achieved in 3%. Long-term relapse of T2DM after initial remission occurred in 44%. Among patients with relapse, 67% maintained glycemic control (HbA1c <7%). On adjusted analysis, taking 2 or more diabetes medications at baseline predicted less long-term remission (odds ratio 0.19, 95% confidence interval 0.07-0.55, P = 0.002) and more relapse of T2DM (odds ratio 8.50, 95% confidence interval: 1.40-49.20, P = 0.02). Significant improvement in triglycerides (-53.7 ± 116.4 mg/dL, P < 0.001), high-density lipoprotein (8.2 ± 12.9 mg/dL, P < 0.001), systolic (-8.9 ± 18.7 mmHg, P < 0.001) and diastolic blood pressure (-2.6 ± 14.5 mmHg, P = 0.04), and cardiovascular risk (13% relative reduction, P < 0.001) was observed.
  
  
  
  LSG can significantly improve cardiometabolic risk factors including glycemic status in T2DM. Long-term complete remission and "cure" of T2DM, however, occur infrequently.
