What are the next steps for a patient with normal Fibroscan (Fibrosis Scan) and liver ultrasound results?

Management of Patients with Normal Fibroscan and Liver Ultrasound Results

For patients with normal Fibroscan and liver ultrasound results, routine follow-up with repeat non-invasive fibrosis assessment in 2-3 years is recommended, unless clinical circumstances change. 1

Understanding the Significance of Normal Results

Normal Fibroscan and ultrasound findings are reassuring indicators that suggest:

• Absence of significant liver fibrosis (Fibroscan <8 kPa indicates low risk of advanced fibrosis) 2, 1
• No evidence of structural liver abnormalities on ultrasound
• Low likelihood of advanced liver disease requiring immediate intervention

Recommended Follow-up Strategy

For Low-Risk Patients (Normal Results)

• Schedule repeat non-invasive testing in 2-3 years 2, 1
• Continue routine health maintenance and risk factor management
• No immediate specialist referral is necessary unless other concerning clinical features are present

Monitoring Parameters

• Annual liver function tests (ALT, AST, GGT, ALP, bilirubin) 2, 1
• Regular physical examination for hepatosplenomegaly 2
• Assessment of metabolic risk factors (diabetes, obesity, dyslipidemia, hypertension) 2

Risk Stratification Framework

The following framework helps determine appropriate follow-up based on Fibroscan results:

Liver Stiffness (kPa)	Risk Category	Recommended Action
<8 kPa	LOW RISK	Repeat non-invasive testing in 2-3 years [2,1]
8-12 kPa	INDETERMINATE RISK	Refer to hepatologist; re-evaluate in 2-3 years [2]
>12 kPa	HIGH RISK	Refer to hepatologist for further evaluation [2]
>16 kPa	POSSIBLE CIRRHOSIS	Urgent hepatology referral [2]

Addressing Specific Risk Factors

Even with normal current findings, patients with risk factors require more vigilant monitoring:

Metabolic Risk Factors

• For patients with type 2 diabetes, obesity, dyslipidemia, or hypertension:
  • Consider more frequent monitoring (every 1-2 years) 2
  • Implement lifestyle modifications (weight loss of 7-10%, Mediterranean diet, physical activity) 1
  • Address metabolic comorbidities to prevent future liver disease 1

Alcohol Consumption

• For patients with significant alcohol intake:
  • Consider risk stratification with FIB-4 index and AUDIT-C questionnaire 2
  • If GGT is elevated (>100 U/L), consider more frequent monitoring 2
  • Recommend appropriate alcohol reduction or cessation 2

Viral Hepatitis History

• For patients with treated viral hepatitis and normal current findings:
  • Continue monitoring according to post-treatment protocols 1
  • Be aware that optimal cut-offs for post-treatment settings differ from pre-treatment values 1

Important Clinical Considerations

Limitations of Non-invasive Testing

• Non-invasive tests perform better at excluding advanced fibrosis than confirming it 1
• Inflammation can falsely elevate liver stiffness measurements 1
• Different elastography systems are not directly comparable; use the same system for longitudinal monitoring 1

Red Flags Requiring Earlier Reassessment

• Rising liver enzymes or bilirubin 1
• New clinical signs of portal hypertension 1
• Development of symptoms such as jaundice, ascites, or encephalopathy 1
• Increase in liver stiffness measurement >1.5 kPa/year on subsequent testing 1

Conclusion

Normal Fibroscan and liver ultrasound results are reassuring findings that generally indicate low risk of significant liver disease. The appropriate follow-up strategy involves periodic reassessment of liver health through non-invasive testing every 2-3 years, with more frequent monitoring for those with specific risk factors. This approach allows for early detection of liver disease progression while avoiding unnecessary interventions for patients at low risk.
