Background

Revisional bariatric surgery (RBS) is performed to address complications from or failure of an initial bariatric procedure. Complications may be surgical/anatomical or nutritional/metabolic, and failures can present as inadequate weight loss or weight regain. The policy defines Revisional Bariatric Surgery (RBS) as surgery to address patients whose original operation was unsuccessful in achieving satisfactory weight loss goals or in whom complications from the original operation have occurred. Inadequate weight loss is defined as less than 50% expected weight loss and/or weight remains greater than 40% over ideal body weight (normal body weight BMI parameter 18.5–24.9).

Guideline references include the ASMBS/IFSO 2022 indications and multiple guideline and literature sources from 2020–2024 supporting the policy.
