Five-Year BAROS Score Outcomes for Roux-en-Y Gastric Bypass, One Anastomosis Gastric Bypass, and Sleeve Gastrectomy: a Comparative Study.

Abstract

Metabolic and bariatric surgery (MBS) has been shown to enhance the quality of life (QoL) in individuals with obesity. The Bariatric Analysis and Reporting Outcome System (BAROS) is a highly reliable scoring system utilized to assess weight loss, obesity-associated medical conditions, and QoL following MBS. This study aimed to assess the efficacy of sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), and one anastomosis gastric bypass (OAGB) in improving health outcomes for individuals with severe obesity, employing the BAROS questionnaire. A retrospective study was conducted, enrolling 299 patients with a body mass index (BMI) of 40 or higher who had undergone primary MBS (RYGB, OAGB, or SG) and had a 5-year follow-up. Patients were evaluated using the BAROS scoring system, which included measures of % excess weight loss (%EWL), improvement and remission of obesity-related medical problems, and postoperative short-term and long-term complications. The mean age and pre-op BMI of the patients was 39.4 ± 9.4 years and 44.6± 6.5 kg/m2, respectively. The total BAROS score was significantly higher in patients who underwent OAGB compared to those who underwent RYGB and SG (P, 0.02). However, no significant differences were observed in other aspects of the BAROS score, such as QoL. This study demonstrated that all three common metabolic and bariatric surgical procedures (SG, RYGB, and OAGB) significantly improved the QoL after surgery. Furthermore, patients who underwent OAGB had a significantly higher total BAROS score at the 5-year follow-up compared to those who underwent RYGB and SG.
