Title: The Impact of Bariatric Surgery on Hepatic Function and Predictors of Liver Steatosis and Fibrosis.
Abstract: PURPOSE: To evaluate the variation in parameters of hepatic function and in the scores Fatty Liver Index (FLI; predictor of hepatic steatosis) and BARD (BMI, AST/ALT ratio and DM, predictor of hepatic fibrosis), 1&#160;year after bariatric surgery. MATERIAL AND METHODS: This is a observational retrospective cohort study in patients with morbid obesity that underwent bariatric surgery in our centre. We used two linear regression models: (1) unadjusted and (2) adjusted for surgery type, sex, age, body mass index, diabetes, and dyslipidaemia. RESULTS: The included population (n&#8201;=&#8201;1955) had an average age of 43.1&#8201;&#177;&#8201;10&#160;years and 85.8% were female. Diabetes was present in 32.4% of the patients, 45.1% had dyslipidaemia, and 62.2% had hypertension. Twelve percent were submitted to gastric band, 29.6% to sleeve gastrectomy, and 58.4% to gastric bypass. We observed a relevant decrease in transaminases and gamma-glutamyltransferase, and an increase in alkaline phosphatase and total bilirubin. Both FLI and BARD markedly decrease 1&#160;year after surgery (p&#8201;<&#8201;0.01). Comparing the surgical procedures, sleeve gastrectomy was associated with a greater reduction of hepatic enzymes and of both FLI and BARD compared with gastric band. Comparing with gastric bypass, sleeve was associated with a greater reduction of transaminases and alkaline phosphatase, but a smaller reduction of FLI and BARD. CONCLUSION: Bariatric surgery is associated with a reduction of the hepatic enzymes and an improvement of FLI and BARD. It may represent an effective therapeutic approach for NAFLD.
