What does liver cancer puncture biopsy mean? It is a method of examination

What does liver cancer puncture biopsy mean? Liver cancer is a malignant tumor with a relatively high incidence and great harm in clinical practice. Cancer is a disease that everyone fears and a difficult problem that has not been overcome in clinical practice so far. Its emergence is very harmful to human health. Puncture biopsy is a common method of clinical diagnosis of cancer. So, what does liver cancer puncture biopsy mean?

Liver puncture is very traumatic, which makes it difficult for many patients to accept it. Liver biopsy is not used as a routine examination in clinical practice. However, the accuracy of liver puncture biopsy is over 80%, which is currently a better examination method. Patients usually need local anesthesia, use negative pressure suction one-second puncture technology, puncture through the skin under the positioning and guidance of B-ultrasound and CT, or directly puncture under the monitoring of laparoscopy.

Liver biopsy pathology is mainly used for differential diagnosis of various liver diseases, such as identifying the nature and causes of jaundice, understanding the extent and activity of liver lesions, providing a basis for etiological diagnosis of various types of viral hepatitis, discovering early, quiescent or compensated cirrhosis, and judging clinical efficacy. It is an internationally recognized "gold standard" in determining the severity of liver fibrosis.

In addition, liver puncture can also be used for diagnostic treatment, such as liver abscess puncture and drainage, liver cyst extraction, liver cancer tumor injection of drugs or anhydrous alcohol, etc. Liver puncture has been used in clinical practice for more than 100 years. With the continuous improvement of puncture instruments and operation methods, the Menghini one-second liver puncture method is now widely used, which is convenient and safe, has a high success rate, and has no obvious adverse reactions.

If patients are selected strictly according to the indications and contraindications of liver puncture, and adequate preparation and care are done before and after the operation, the original liver lesions will not be aggravated, and the condition will not be aggravated. Clinical diagnosis of diseases often has certain deviations, and only pathological diagnosis is truly reliable.

In order to make liver puncture safer, it is recommended that patients undergo routine liver biochemistry tests, coagulation function tests, blood routine, platelet, chest X-ray, and abdominal ultrasound examinations 1 to 2 days before liver puncture; in addition, 10 mg of vitamin K1 needs to be injected once a day before liver puncture and on the day of surgery.
