The Impact of Metabolic and Bariatric Surgeon Status on Outcomes After Bariatric Surgery: a Retrospective Cohort Study Using the MBSAQIP Database.

Purpose: Differences between complication rates of bariatric surgeries performed by general surgeons (GS) versus those performed by metabolic and bariatric surgeons (MBS) are poorly understood.

Methods: We analyzed the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database focusing on RYGB and SG procedures between 2016 and 2019. Our primary objective was to evaluate trends in the number of bariatric procedures performed by GS and MBS.
