    The ASA-PS classification system assesses peri-operative risk based on physical condition, including BMI as a criterion since 2014.

  • 2

    Patients with a BMI ≥ 40 kg/m2 may not accurately reflect peri-operative risk due to varying obesity phenotypes and metabolic health.

  • 3

    Metabolically healthy obesity is characterized by lower visceral fat and inflammation, leading to a reduced risk of cardiovascular disease.

  • 4

    Increased BMI alone does not predict peri-operative complications, as risks are often linked to metabolic diseases rather than obesity itself.

  • 5

    The study aims to evaluate whether ASA-PS III classification based solely on BMI ≥ 40 kg/m2 correlates with lower complication rates compared to other ASA-PS III patients.
