What liver piercing needle can detect liver disease to come

The value of liver puncture biopsy has the following eight points:
1. It is beneficial to the differential diagnosis of various liver diseases
Many chronic liver diseases that are difficult to diagnose clinically, such as viral hepatitis, alcoholic hepatitis, liver tuberculosis, liver granuloma, schistosomiasis, liver tumor, fatty liver, liver abscess, primary biliary cirrhosis and various metabolic liver diseases (Wilson's disease, liver glycogen accumulation disease, liver amyloidosis), etc., often need liver aspiration to understand the liver lesions of patients. Provide important and possibly decisive evidence for a definitive diagnosis.
2. Understand the extent and activity of liver lesions
Liver biopsy is a kind of examination method that can directly understand the pathological changes of liver tissue and make objective and accurate diagnosis. Many patients with chronic hepatitis B have been infected with liver disease virus for a long time, but the abnormal transaminase found in blood tests may only be half a year, and the content level of liver disease virus is not high. In such patients, liver puncture can detect whether the chronic liver disease is in the active stage, and infer the severity of the lesions.
3. Etiological diagnosis of various types of viral hepatitis is provided. Most hepatitis viruses are hepatophil viruses, which are often parasitic in liver tissue. Only when serum liver disease virus reaches a certain level can clinical assay detect it. So there are still some viral hepatitis, clinical tests show that the serum liver disease virus markers are all negative, it is difficult to determine the etiology. However, hepatitis virus parasitized in liver tissue can be detected by liver puncture, ultra sensitive immunohistochemistry and in situ molecular hybridization.
4. Detection of early, still or compensatory cirrhosis Cirrhosis, especially liver fibrosis, in the early stages of the disease, by blood tests, B-ultrasound examination is generally difficult to detect. However, liver biopsy allows accurate diagnosis of hepatic fibrosis and incipient, dormant, or compensatory cirrhosis, and enables the identification of clinical types of cirrhosis, including alcoholic cirrhosis, posthepatitis cirrhosis, and the presence or absence of active hepatitis. For example, some patients diagnosed as chronic asymptomatic liver disease virus carriers may be found to have active cirrhosis or chronic active hepatitis by liver biopsy.
