SF-BARI Score for assessment of long-term results in patients with BMI ≥ 50 Kg/m2 submitted to Roux-en-Y Gastric Bypass or Sleeve Gastrectomy

Introduction: To improve treatment of patients with BMI ≥ 50 Kg/m ² , it is necessary to standardize reports and to assess long-term outcomes. The SF-BARI score was developed to provide a comprehensive evaluation of MBS outcomes. This article explores the long-term results of RYGB and SG in patients with BMI ≥ 50 Kg/m ² using the SF-BARI Score, and assesses variables that may influence this score. Methods: Retrospective cohort study of patients with BMI ≥ 50kg/m ² submitted to Roux-en-Y Gastric Bypass (RYGB) or Sleeve Gastrectomy (SG) between January 2010 and September 2021, with more than 5 years of follow-up. Several data were collected, and the SF-BARI score was calculated and analyzed. Statistical analysis was performed to identify variables that influenced the score. Results: We identified 89 patients with long-term follow-up (mean 96.6 months, SD 18.9) after RYGB or SG. The mean SF-BARI score was 94.2 (SD 29.5) with most patients’ outcomes categorized as Good. Seventy-six (85.4%) patients had %TWL ≥ 20, but only 34.8% patients had a final BMI < 35 kg/m². Statistical analysis revealed that younger patients have higher SF-BARI score related to comorbidities improvement. Conclusion: Our findings suggest that both RYGB and SG lead to satisfactory long-term outcomes for treatment of patients with BMI above 50 kg/m², according to the SF-BARI Score. However only one third achieved a BMI below 35 kg/m². Younger patients seem to achieve better results, particularly comorbidity improvements. SF-BARI score is a comprehensive and intuitive web-based tool that may contribute for the standardization of reporting outcomes after MBS.
