• Abstract:

  Bariatric surgery has emerged as an effective intervention to address severe and morbid obesity, resulting not only in sustained weight loss but also in improvements in associated health conditions. In this integrative review, we explore a comprehensive analysis of the various surgical approaches, related complications, and long-term outcomes linked to bariatric surgery. The period of analysis covers studies published between 2013 and 2023, with the aim of providing a comprehensive and up-to-date overview of the subject. The research addressed clinical and observational studies that analyzed bariatric surgery procedures in the context of the approaches employed, resulting complications and long-term outcomes. We examined studies that compared different surgical techniques, including multicenter clinical trials and longitudinal studies. The analysis focused on comparing outcomes between procedures such as single-anastomosis gastric bypass (OAGB), Roux-en-Y gastric bypass (RYGB), and sleeve gastrectomy (SG), with an emphasis on weight trajectories, complications, and metabolic results. The results highlighted the importance of comparing different surgical techniques so that one can examine the efficacy and safety of OAGB versus RYGB. Additionally, the Longitudinal Assessment of Bariatric Surgery (LABS) Study provided valuable insights into long-term weight trajectories after bariatric surgery. Discussions of complications highlighted the challenges and potential risks associated with bariatric surgery. By integrating analysis of several studies, this review offers a broad view of the efficacy, safety and complexities of bariatric surgery. Comparisons between surgical approaches, long-term weight and metabolic outcomes, as well as potential complications, provide essential information for clinical decision-making and to guide patients in the management of obesity. Standardization of results and consideration of diabetes severity are crucial components in determining the most appropriate surgical approach.
