Background: Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) are performed in patients with obesity and type 2 diabetes mellitus (T2DM). The aim of this study is to evaluate retrospectively the clinical efficacy of RYGB and SG in two groups of obese T2DM patients. Methods: From the hospital database, we extracted the clinical records of 31 obese T2DM patients, of whom 15 (7 F/8 M) had undergone laparoscopic SG (LSG) and 16 (7 F/9 M) laparoscopic RYGB (LRYGB) in the period 2005-2008. The groups were comparable for age (range 33-59 years) and BMI (range 38-57 kg/m2). LRYGB alimentary limb was 150 cm, and biliopancreatic limb was 150 cm from the Treitz ligament. LSG vertical transection was calibrated on a 40-Fr orogastric bougie. Data were analysed at 6, 12 and 18-24 months with reference to weight loss and remission of comorbidities. Results: The reduction in body weight was comparable in the two groups. At 18-24 months the percent BMI reduction was 29±8 and 33±11 % in LSG and LRYGB, respectively. Percent excess weight loss was 53±16 and 52±19 % in LSG and LRYGB, respectively. Thirteen patients in LSG and 14 patients in LRYGB discontinued their hypoglycaemic medications. Five (55 %) patients in LSG and eight (89 %) in LRYGB discontinued antihypertensive drugs. Three out of five patients in LSG and one out of two patients in LRYGB withdrew lipid-lowering agents. Conclusions: LSG and LRYGB are equally effective in terms of weight loss and remission of obesity-related comorbidities. Controlled long-term comparisons are needed to establish the optimal procedure in relation to patients' characteristics. © 2012 Springer Science + Business Media, LLC.
