Effects of Sleeve Gastrectomy Versus Gastric Bypass on Type 2 Diabetes Mellitus Remission in Obese Patients

Abstract

AbstractObjectives: To determine and compare the efficacy of two weight-reducing surgicalinterventions, gastric bypass (GBP) and sleeve gastrectomy (SG), in inducingremission/improvement of type 2 diabetes mellitus (T2DM). Materials and Methods:Data were collected from 162 obese T2DM subjects who underwent SG (96) or GBP(66) between 2009 and 2011. The following parameters were recorded: body massindex, waist-hip-ratio, blood pressure, fasting plasma glucose, HbA1c, lipid profile,hypoglycemic drugs used. Results: Remission of T2DM was achieved in 83% ofpatients who underwent SG and in 81% of patients who underwent GBP. For bothprocedures, T2DM remission rate was higher for patients with a shorter duration ofT2DM, with better preoperative glycemic control and for those not requiringpharmacological agents before surgery. Conclusions: SG and GBP are effective ininducing T2DM remission in obese patients. The clinical features of T2DM areimportant predictors for the remission of the disease after bariatric surgery.
