What is A Laparoscopic Liver Biopsy
Not every liver tumor needs a liver biopsy to confirm diagnosis. However, in many circumstances, a diagnosis to confirm tumor type/subtype and to guide further treatment is unable to be made without a tissue sampling. Percutaneous CT-guided or ultrasound-guided liver biopsy by an interventional radiologist is the most common way of obtaining liver biopsy. When the liver tumor is located on the left side of the liver, an endoscopic liver biopsy can also be done as an alternative method.
Laparoscopic biopsy is needed in a small percentage of patients in whom percutaneous or endoscopic liver biopsy fails to obtain adequate tissue sample. Dr. Iswanto Sucandy performs laparoscopic liver biopsy via a single incision in the umbilicus, as an outpatient procedure.
Laparoscopic biopsy is also frequently performed to diagnose liver parenchymal abnormalities such as significant fatty liver condition, liver cirrhosis, and when a liver mass is found incidentally during an abdominal operation for other reasons. A larger piece of liver specimen can also be sent for tumor genetic and molecular analyses.
