Obesity and type 2 diabetes mellitus have become lately important public health problems. The increase of diabetes is closely related to the increase of obesity. The bariatric surgeries appeared in the last fifty years, and have become popular as an effective therapeutic option for reducing weight and for controlling or even reverting diabetes in obese patients. Among the available surgery techniques the sleeve gastrectomy, which was used as an inner part of the bilio-pancreatic diversion technique or as first step in high risk patients in order to prepare them for the final surgery, has been used by some surgeons groups as a definitive technique. As its use as a definitive bariatric procedure is quite recent, there are still not enough studies to evaluate its effectiveness. The present study aims at evaluating the sleeve gastrectomy as a technique for the control or reversion of the type 2 diabetes mellitus in obese patients. Therefore, a systematic review was done. A research in the existing literature presented 698 titles and summaries. After applying the inclusion criteria, 96 complete texts were considered; seven papers with controlled clinic tests were included in the systematic review. This allowed to perform a metanalysis between studies, comparing the sleeve gastrectomy with the Roux-en-Y gastric bypass and with the adjustable gastric band. The comparison was based on the evaluation of the outcome of fast glycemia and glucosided hemoglobin. The result of the metanalysis was favorable to the sleeve gastrectomy, in comparison to the Roux-en-Y gastric bypass, for the closing of the post-surgery reduction of the glycoside hemoglobin. The sleeve gastrectomy thus appears as another therapeutic option towards obesity and correction of the related co-morbidities. But the results are still at an early stage, and so controlled clinical tests with high quality methodology are required in order to achieve a better evaluation.
