GLP-1 Agonists, Behavioral Interventions, and Revisional Surgeries Effectively Manage Weight Recurrence After Bariatric Surgery

Weight recurrence (WR) is the primary long-term complication following bariatric surgery (BS), often necessitating revisional procedures and undermining initial treatment success. This challenge stems from a complex interplay of biological adaptation, anatomy, behavior, and mental health. Current standard-of-care often falls short in providing sustained weight loss for patients experiencing WR, highlighting a critical gap for effective, multidisciplinary management strategies. Understanding the efficacy and safety of various interventions, including novel pharmacotherapies targeting pathways like GLP-1R, is crucial for optimizing long-term outcomes.

This comprehensive literature review characterized the efficacy and safety of strategies for managing weight recurrence (WR) after bariatric surgery (BS). Researchers systematically analyzed published literature, focusing on both medical and surgical management alternatives, including revisional procedures. The review compared outcomes primarily in terms of percent excess weight loss (%EWL) and associated complication rates across different interventions. The aim was to provide a detailed overview of current best practices for addressing WR, encompassing behavioral, pharmacological, and surgical approaches.

Management of weight recurrence (WR) after bariatric surgery (BS) requires a multifaceted approach combining lifestyle modifications, pharmacotherapy, and surgical options. Behavioral interventions, including remote monitoring programs like the HELP platform, consistently demonstrated efficacy in improving weight loss outcomes. Pharmacotherapy showed promising results, with GLP-1 agents such as liraglutide and semaglutide proving effective, alongside combinations like naltrexone/bupropion, though their utility is sometimes limited by local availability. Revisional surgical interventions, including endoscopic procedures like TORe and ROSE, as well as advanced options such as duodenal switch and distal gastric bypass (RYGB), also demonstrated significant efficacy. These surgical approaches, however, necessitate considerable experience and a robust multidisciplinary team for optimal patient selection and management. The review emphasized that a tailored, stepwise management plan, progressing from behavioral to pharmacological and then surgical interventions, is key to addressing the multifactorial causes of WR. Each strategy contributes to improving weight loss, albeit with varying profiles of associated complications. The overall findings underscore the importance of defining patient expectations from the outset and thoroughly evaluating anatomy and nutritional deficiencies before considering revisional surgery to minimize risks.
