Results
It was verified a significant reduction of liver ARFI values since the average shear wave velocity declined from 1.74±0.9m/s before surgery to 1.26±0.8m/s after surgery (p<0.02). Fig. 1

Moreover,
it was detected liver steatosis with ultrasound in 67,5% (n=27) of patients before the procedure.
Severe steatosis was found in 12.5% of patients before surgery.
After surgery,
only 7,5% (n=3) patients had liver steatosis.
These data reflect a significant decrease of liver steatosis after treatment (p<0.0001). Fig. 2

Furthermore,
it was determined a significant decrease of BMI,
total cholesterol,
low-density lipoproteins and triglycerides after the intervention (p<0.003). Fig. 3 Fig. 4

No significant improvement of glutamate pyruvate transaminase,
glutamate oxaloacetate transaminase nor platelets levels was found.
The results of liver elastography,
together with clinical and analytical data and ultrasound features,
reflect regression of non-alcoholic steatohepatitis after bariatric surgery.
