- 3. Preparation • Consent • Absence of followings • Ascites • Significant extrahepatic biliary obstruction • Encephalopathy • Coagulopathy- PT > 4sec and PC < 60k • Renal failure • CCF • Cystic lesion in liver- Hydatid cyst • Pre-biopsy USG for anatomical abnormalities- Chilaiditi syndrome, IH GB
- 4. Methods • Percutaneous blind • Percutaneous image guided • Transvenous-TJ • Laparoscopic
- 5. What are the Needle used? • Suction needle- Menghini, Jamshidi, Klatskin • Cutting needle- Tru-cut, spring loaded needle
- 9. Procedure
- 10. Indications • Drug-induced hepatitis • Chronic hepatitis B or C • Discordance in NIT and clinical feature • Suspected concomitant liver disease • Post-antiviral therapy • Chonic cholestatic liver disease • MRCP negative biliary obstruction • PBC- staging and progression • Small duct PSC
- 11. Continued.. • Fatty liver- steatohepatitis • Steatosis • Ballooning • Lobular inflammation • Before LT • Occult fibrosis • Steatosis • Inflammation • SOL in liver- indistinguishable from primary vs secondary
- 12. Continued.. • Unexplained hepatomegaly • Unexplained liver enzyme elevation • Storage disease
- 13. Special application • Immuno-histochemical study for tumor marker • HCC vs CC • Early HCC vs Dysplastic nodule • HCC vs Metastatic adenocarcinoma • HCC- Hep-par1, pCEA, CD10, CD34 • CC- cytokeratin7,19 • Early HCC- glypican-3, HSP-70
- 14. Interpretations • Specimen 2 to 3cm long and contain at least 11 portal tract. • Finding are • Portal inflammation • Lobular inflammation • Ductal reaction- ductopenia >50% • Steatosis • fibrosis
- 15. Scoring system • Knodell • Modified knodell/ Ishak • Metavir • Ludwig system- PBC
- 16. Ishak scoring system Stage Findings 1 Fibrous expansion of some portal areas ± short fibrous septa. 2 Fibrous expansion of most portal areas ± short fibrous Septa 3 Fibrous expansion of most portal areas with occasional portal to portal (P-P) bridging. 4 Fibrous expansion of portal areas with marked bridging (poral to portal (P-P) as well as portal to central (P-C)). 5 Marked bridging (P-P and/or P-C), with occasional nodules (incomplete cirrhosis). 6 Cirrhosis, probable or definite.
