The American Society for Metabolic and Bariatric Surgery (ASMBS) and MBSAQUIP-A on March of 2019, published and updated list of “Endorsed Procedures and Devices”
Note that any surgical procedures that does not employ two anastomosis, are not endorsed and are only recommended to be performed with an IRB (Institutional Review Board) or an IRB exemption. Duodenal Switch, Sleeve Gastrectomy, Roux en Y Gastric Bypass, Gastric Balloon, Adjustable Gastric Banding, and Nerve Blocking which are endorsed procedures.
SIPS, SADI-S, SIPS, Loop DS are all in the category of the “Non-Endorsed Procedures and Devices”. To see an anatomical comparison of these procedures to the Duodenal Switch procedure.
Patients should request that their consent be clearly defined and should explicitly outline the procedure that is being proposed to them. This is to avoid a patient having a procedure that they assumed, or are led to believe to be a Duodenal Switch operation with two anastomosis. Do your due diligence and know the procedure you want. Investigate if the surgeon you are working with performs the procedure you are interested in. Have them draw a picture of the procedure or give you a diagram of the procedure.
