The hepatic biopsy is necessary for the evaluation of chronic hepatitis. Its usefulness is relies on the assessment of the inflammation degree and fibrosis of the patient with chronic hepatitis. The use of a semi quantitative system for the classification of chronic hepatitis biopsies is necessary to keep less subjective parameters and to compare its evolution for a potential therapy. A semi quantitative score is established to determine the degree and staging. For the assessment of a hepatic biopsy, it is important to get at least 3-5 porta spaces and perform routine tinctions as hematoxylin-eosin, trichromic, reticulite and orcein. This is essential for the definition of treatments, inflammatory activity and fibrosis stage, supporting the clinical, biochemical, and molecular biology parts of the viral burden of the hepatitis B virus.

Palabras clave : chronic hepatitis; hepatic biopsy; hepatic fibrosis stage; chronic lobular hepatitis.
