The ASMBS recognizes a defined set of endorsed procedures as safe, effective, and evidence-based interventions for the treatment of metabolic and bariatric disease. These procedures reflect current clinical best practices and are suitable for use as primary surgical treatments at MBSAQIP-accredited centers, without requiring Institutional Review Board (IRB) approval.
Any procedure not included on the ASMBS endorsed list must undergo IRB review and approval before it can be implemented as a primary treatment. This approval must apply to the conduct of the procedure itself, not solely to data collection. If an IRB deems a study protocol unnecessary, a letter of exemption is required to demonstrate compliance with MBSAQIP standards. While re-operative procedures are exempt from IRB requirements, ASMBS encourages alignment with endorsed procedures whenever clinically appropriate.
Procedures not listed below have either not been endorsed or have not yet been completed for review through the ASMBS Pathway for Approval of New Procedures. Any ASMBS member can submit a procedure for review.
