Which procedure is a form of biopsy that specifically targets the liver?

The procedure that specifically targets the liver is a liver biopsy, which is designed to remove a small sample of liver tissue for examination under a microscope. This procedure is essential for diagnosing various liver conditions, including hepatitis, cirrhosis, and liver cancer. It allows healthcare providers to assess liver function and determine the extent of liver disease.

In the context of the other options, colonoscopy involves examining the colon and rectum, commonly used to detect abnormalities in those areas. Laparoscopy refers to a surgical technique that allows access to the abdominal cavity through small incisions but is not specifically aimed at the liver. Endoscopy generally refers to examining the interior of a hollow organ or cavity of the body using an endoscope, but again, it does not specifically target the liver. Thus, the liver biopsy stands out as the targeted procedure for liver assessment, making it the correct choice.
