Liver biopsy is generally performed to evaluate parenchymal disease, and which biopsy methods are appropriate?

• A. Biopsy forceps
• B. Peritoneal washings
• C. Fine-needle aspiration
• D. Core needle or wedge

Answer: (D)

Evaluating diffuse liver disease relies on tissue that preserves the liver’s architecture so you can assess fibrosis, inflammation, and overall parenchymal pattern. A specimen that keeps the lobular architecture and includes portal tracts is essential for accurate histologic grading and staging. Fine-needle aspiration pulls cells but loses the architectural context, making it unreliable for parenchymal disease evaluation. Peritoneal washings don’t sample liver tissue at all, so they don’t help assess liver parenchyma. Biopsy forceps can obtain tissue, but the most informative and routinely used samples are from a core needle biopsy or a wedge biopsy, both of which provide intact architecture and sufficient tissue for proper histologic assessment. A core needle biopsy is the common percutaneous approach, while a wedge biopsy is obtained during open or laparoscopic procedures.
