Prevalence and risk factors of liver fibrosis in patients with metabolic-associated fatty liver disease undergoing bariatric surgery

Significant fibrosis (F ≥ 2) was detected in > 1/3 of patients with MAFLD undergoing bariatric surgery. Presence of smoking, diabetes, hypertension, high WHR, elevated serum uric acid, advanced age, and low platelet level are risk factors for significant fibrosis (F ≥ 2). Noninvasive models, FIB-4, NFS, and APRI can be used to identify significant liver fibrosis in bariatric surgery patients.
