A comparative trial of liver biopsy needles . A sheathed needle ( Tru-Cut ) was compared with a suction biopsy needle ( Menghini ) in a randomised prospective trial over 18 months to determine whether the former offered any special advantages in routine percutaneous liver biopsy . Seventy-seven consecutive biopsies were performed by a single operator . Although biopsy fragmentation was commoner with the suction needle , the length and volume of the largest core obtained was similar to results with the sheathed needle . Cytology provided useful additional information with the Menghini technique . The suction needle was repeatedly reusable and considerably cheaper than the sheathed needle , which may be used once only .
