Background: The prevalence of obesity and T2DM has increased dramatically worldwide, becoming a serious global public health problem. Bariatric surgery should be considered as an alternative line for treating patients with a BMI of 30–35 kg/m2 when DM cannot be controlled by medical regimen.With the exception of omentectomy, which has proven to be totally ineffective, the newly developed operations specifically designed for T2DM treatment ' duodeno-jejunal bypass and ileal transposition (DJB &IT) were inspired by the two known hypothesis (hindgut & foregut theory). Patients and methods: A prospective randomized control trial study at Ain-shams university hospital using the closed envelop method was held at Ain Shams university hospitals, from February 2014 up to July2016 upon 40 obese patients with BMI between 30-35sufferring from type II DM comparing duodeno-jejunal bypass and ileal transposition regarding their effect on glycemic control. Results: In this study, the 20 patients who had DJB, the mean FBG decreased from 257 mg/dl to 106 mg/dl, and the 2H-PP value also decreased from 335 mg/dl to 161 mg/dl with improvement of HbA1c from 9 gm% to 5.7 gm%. The S. insulin level increased from 9.8 miu/ml to 12.4 miu/ml , with associated increased C-Peptide from 0.9 ng/ml to 1.2ng/ml.In the 20 patients who had ITthe FBG decreased from 265 mg/dl to 92 mg/dl, and the 2H-PP value also decreased from 347 mg/dl to 143 mg/dl with improvement of HbA1c from 8.8gm% to 5.4gm%. The S. insulin level increased from 9.6miu/ml to13.6 miu/ml, with associated increased C-Peptide from 0.9ng/ml to 1.4ng/ml. Conclusion: These data provide preliminary evidence about the benefits of metabolic surgery on the glycemic control of T2DM obese subjects with a BMI of < 35 kg/m2.However, more randomized controlled trials are needed to investigate the effects of surgery in T2DM remission in pre-obese patients.
