The role of liver biopsy

Liver biopsy is an invasive test. For patients with chronic hepatitis, liver biopsy is very important. The purpose of liver biopsy is to determine the actual damage of the liver, and to determine whether to treat or treat according to the results of pathological examination. For those patients with atypical conditions, especially those whose liver function fluctuates for a long time, but the serum biochemical test does not meet the antiviral indications, it is especially important to avoid the abuse of antiviral drugs or delay the timing of treatment, resulting in bad consequences.

Clinical results show that there is a positive correlation between the activity of inflammation and the effective rate of antiviral drugs. In patients with G3 or above, the proportion of seroconversion can even reach more than 80% with antiviral drugs. Therefore, liver biopsy is also the best diagnosis and treatment for drugs. standard. In addition, it is of great value to perform liver biopsy before antiviral treatment and compare it with the situation after treatment to judge the effect of treatment and prognosis. Liver biopsy is very safe. It is operated under the guidance of color Doppler ultrasound, and the location and depth of the puncture can be accurately located. It only takes out one-third of the liver, which is less than 1mm thick and 15mm long, and the damage to the liver is negligible. Liver biopsy can be performed as long as the patient has normal coagulation function, less severe jaundice, and no hepatic hemangioma or decompensated cirrhosis. Liver biopsy pathology can determine the degree of inflammation, fibrosis, and the presence or absence of hepatitis B and C viruses in the liver. Liver biopsy is suitable for liver damage caused by various reasons, especially for virus carriers, chronic hepatitis, intrahepatic space-occupying and undiagnosed liver damage. At present, the medical community regards this test as the gold standard for diagnosing the cause of liver disease and determining the curative effect.
