Small Animal Liver Biopsy

For a nonperipheral biopsy or a biopsy of a specific nodule or mass, a 4-mm or 6-mm Baker’s punch is commonly used. The punch is positioned perpendicular to the tissue and is rotated to cut a cylinder of liver parenchyma. Gelatin sponge aids in clot formation and is placed in the defect in lieu of suturing.
