Under what circumstances do liver puncture

The so-called liver biopsy is the application of a disposable liver biopsy needle under B-ultrasound positioning or guidance (most hospitals now use it, and the previous negative pressure suction method will be much more convenient and safer). It is about the eighth rib on the right side. The liver is inserted into the liver, and a small piece of liver tissue is clipped for pathological slices and laboratory tests. G is the degree of inflammation, which is divided into 5 levels: 0, 1, 2, 3, and 4. The higher the level, the more severe the inflammation, and the S is the degree of fibrosis. , Is also divided into 5 levels as above, and at level 4 is liver cirrhosis. Liver puncture has a certain traumatic nature, and it is not easy for many patients to accept it. In clinical practice, liver biopsy is not used as a routine examination. There are many patients with chronic hepatitis B who have been infected with the liver disease virus for a long time, but the blood test found that the transaminase is abnormal for only half a year, and the level of liver disease virus is not high. Such patients can find out whether the chronic liver disease is in the active phase through liver puncture, and can infer the severity of the disease.
