What Is Liver Histology

The acquisition of pathological tissue for histological examination (observation of subtle tissue variation under light microscope) is of decisive significance in the diagnosis of disease. Similar to the method of operation, cells were aspirated for cytology, but the accuracy of cytology was not as good as that of histology, with a certain false-negative rate, and the accuracy of histology was 100% on the premise of successful sampling.

The procedure for histological biopsy of the liver is as follows. Under the guidance of B-mode ultrasound images, the doctor holds the B-mode ultrasound probe and the medical biopsy needle (generally, the biopsy needle is fixed on the B-mode ultrasound probe through a special adapter, except for freehand puncture) and directly impinges the intercostal skin. After reaching the lesion, the puncture needle is ejected to cut the pathological tissue, and the needle is quickly removed.

Now, due to the improvement of puncture needles, the safety of puncture histology biopsy has been significantly improved, and the use of liver histology biopsy is becoming more and more common, while the use of aspiration cytology is gradually decreasing.
