Conventionally, liver biopsies are obtained by surgery, through percutaneous or transjugular. All that are good options but all have disadvantages as costs, complications risk, or invasiveness grade. Recently, endoscopic ultrasound-guided liver biopsies have showed good diagnostic yield in patients with solid liver lesions; however, in patients without solid lesions have been unsatisfactory. This problem has related to the kind of needles used. Recently, needles with a new design for liver biopsies have been created.
