Is a liver biopsy painful? How long does it take?

Liver biopsies are usually painless during the procedure, but can be mildly painful six hours after completion. The whole process takes about half an hour, and the exact time varies from person to person.

Liver biopsy refers to taking a small amount of tissue from the liver by puncture for pathological examination. Usually, liver biopsy is required because there is a space-occupying lesion in the liver, and it is impossible to determine whether it is benign or malignant. Liver biopsy does not cause much damage to the liver, but liver biopsy is an invasive operation that may cause certain risks of complications, including bleeding, arteriovenous fistula, intrahepatic infection, biliary fistula, etc. If it is a biopsy of the tumor, it may also cause needle tract metastasis of the tumor, tumor rupture, and so on.

Liver biopsy usually requires local anesthesia, then the needle is inserted vertically under ultrasound or laparoscopic guidance and punctured into the site of the lesion, then the tissue is removed and a biopsy is scheduled. The process generally does not take long, for experienced doctors, it takes about half an hour.
