Why do we need a liver puncture needle? Is liver puncture harmful to the body?

Liver puncture is both an examination method and a treatment method. When there are some undiagnosed liver diseases in the clinic, liver puncture should be considered: such as suspected gastrohepatitis but difficult to diagnose, or those who need pathological examination to assist classification; long-term low-grade fever cases, other patients have been excluded after comprehensive examination. Those caused by liver disease; those with unknown causes of hepatomegaly and splenomegaly, or those who need to be differentiated from diseases such as liver tuberculosis and fatty liver; those with unclear liver damage caused by viral and drug-induced diseases, and so on. In addition, patients with liver abscess can get pus through liver puncture, and at the same time can inject drugs through puncture needles, so that some patients can avoid the pain of surgery. After liver puncture, some patients will have short-term liver pain or pain at the liver puncture site, but the reaction is generally mild and does not require treatment. It can be relieved by itself after 24 hours. At present, some hospitals have adopted B-guided fine needle puncture, which has the advantages of less damage and accurate positioning, which is especially suitable for determining the nature of intrahepatic space-occupying STDs. Some people think that liver puncture will damage the "vital energy", so when doctors propose to do liver puncture, they are often very nervous, worried, and feel uncomfortable in one way or another after the operation. After the doctor gives a detailed explanation to the patient, the discomfort will quickly disappear, which shows that mental factors account for a large proportion. However, when the patient has bleeding tendency or other contraindications, the action should be delayed or not. (1) It can be clear whether there is liver cirrhosis.
