COMPARISON OF HEPATIC PROFILE IN PRE AND POSTOPERATIVE OF BARIATRIC SURGERY: PRIVATE VS PUBLIC NETWORK

Background:

Obesity is associated to several comorbidities, including nonalcoholic fatty liverdisease, which implicates in isolated steatosis to steatohepatitis. The latter mayprogress to severe manifestations such as liver fibrosis, cirrhosis andhepatocellular carcinoma.

Aim:

To compare the presence of advanced liver fibrosis before and after bariatricsurgery in patients of private and public health system.

Methods:

Patients from public and privative networks were studied before and afterbariatric surgery. The presence or absence of advanced hepatic fibrosis wasevaluated by NAFLD Fibrosis Score, a non-invasive method that uses age, BMI,AST/ALT ratio, albumin, platelet count and the presence or absence ofhyperglycemia or diabetes. The characteristics of the two groups were compared.The established statistical significance criterion was p<0.05.

Results:

Were analyzed 40 patients with a mean age of 34.6±9.5 years for private networkand 40.6± 10.2 years for public. The study sample, 35% were treated at privatehealth system and 65% in the public ones, 38% male and 62% female. Preoperativelyin the private network one (7.1%) patient had advanced liver fibrosis anddeveloped to the absence of liver fibrosis after surgery. In the public eight(30.8%) patients had advanced liver fibrosis preoperatively, and at one year afterthe proportion fell to six (23%).

Conclusion:

The non-alcoholic fatty liver disease in its advanced form is more prevalent inobese patients treated in the public network than in the treated at the privatenetwork and bariatric surgery may be important therapeutic option in bothpopulations.
