title: [Diagnostic ability of various biopsy needles].
abstract: We compared the diagnostic ability of various biopsy needles. A liver of an anesthetized rabbit was biopsied using 8 needles for cytology (23G, 22G, 21G Spinal; 23G, 22G, 21G Chiba; 22G Westcott; 22G Rotex II) and 12 needles for histological core biopsy (21G, 18G Sonopsy; 23G, 21G, 19G, 17G Sure-cut; 21G Majima; 18G, 16G, 14G Quick-cut; 14G Tru-cut; 18G Roth-biopsy). The volume of the recovered cells was not dependent on the bore of the needles for cytological biopsy (21-23G). However, the volume of the recovered tissue was dependent on the bore of the needles for core biopsy (14-23G). 22G Westcott needle and 22G Rotex II needle both showed excellent ability to obtain large amount of cells. 21G Sure-cut needle and 21G Majima needle both could obtain enough volume for histological diagnosis.
