Ileal transposition in surgical treatment for type 2 diabetes mellitus

Abstract

High prevalence and insufficient efficacy of medical treatment in type 2 diabetes mellitus (T2DM) poses a major challenge for medical care. Generally, only 30% of patients reach therapeutic goals, while remission occurs only in the minority of patients. In the obese (BMI>35 kg/m2), bariatric surgery provides an alternative to pharmacological treatment of T2DM, boosting remission/compensation rate up to 76.8%. A few recent clinical studies explored the anti-diabetic effect of ileal transposition (IT). This type of surgery targets restoration of incretin balance by proximal transposition of ileal segment. In this review, we discuss the salutary mechanisms of IT in T2DM based on the analysis of the pioneering clinical trials.
