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.
在一项为期18个月的随机前瞻性试验中，将套管针（Tru-Cut）与抽吸活检针（Menghini）进行了比较，以确定前者在常规经皮肝活检中是否具有任何特殊优势。由一名操作人员连续进行了77次活检。尽管使用抽吸针时活检组织破碎更为常见，但获得的最大组织条的长度和体积与套管针的结果相似。细胞学检查通过Menghini技术提供了有用的额外信息。抽吸针可反复使用，且比只能使用一次的套管针便宜得多。
