endoluminal sleeve mechanisms
Endoluminal Sleeve: Mechanisms
  • Isolation of Duodenal Mucosa from Nutrients Contact
  • Bile isolated from nutrients
  • No expedited delivery of nutrients to the distal gut
endoluminal sleeve clinical applications
Endoluminal Sleeve: Clinical Applications
  • Primary Therapy of Diabetes ?
    • Long-term ?
    • BMI> 35 ?
    • BMI < 35 ?
  • Diagnostic value ?
  • Pre-surgical Test to select candidates for gastric bypass surgery
  • Integrated Interventional-Drug approach
    • “Adjuvant Therapy”

Bariatric surgery should be considered for adults with BMI > 35 kg/m2 and type 2 diabetes, especially if the diabetes is difficult to control with lifestyle and pharmacologic therapy. (B)

  • Surgery should be considered in pts with BMI > 35 and inadequately controlled diabetes.
slide28

in patients with type 2 diabetes and BMI of 30–35kg/m2, there is currently insufficient evidence to generally recommend surgery in patients with BMI35 kg/m2 outside of a research protocol.

  • Surgery may be considered as a non-primary alternative in pts with uncontrolled diabetes and BMI 30-35.

  • Controlled clinical trials in these patients should be performed to determine the safety and efficacy of GI metabolic surgery (A) as well as to identify parameters other than BMI as criteria for appropriate patient selection (A).

DSS- Research

  • Randomized controlled trials are strongly encouraged to assess the utility of GI surgery to treat T2DM (A). In patients with BMI <35 kg/m2, determining the appropriate use of GI surgery for the treatment of T2DM is an important research priority (A).
