What is a liver Biopsy?
A liver biopsy involves taking a small sample of tissue from your liver. The sample is then looked at under a microscope or sent for further analysis to diagnose or monitor conditions. The biopsy may be of a lesion (mass) in the liver to help determine the nature of the lesion. It is rarely needed due to the accuracy of modern imaging techniques. Alternatively it may be of the liver tissue itself to help understand abnormalities in your liver tests.
How is a liver biopsy taken?
A liver biopsy can be performed either through the skin (percutaneously) or at the time of surgery (open surgery or laparoscopically). If performed percutaneously it is usually done under local anaesthetic. The procedure takes a matter of minutes, but afterwards you will need to be observed for a few hours before being allowed to go home.
Does having a liver biopsy hurt?
There may be some discomfort or pressure, but because it is done under local anaesthetic you should not feel pain.
