Traditional and disposable liver biopsy needles are expensive and add to economic burden in developing countries where the prevalence of liver disease requiring liver biopsy is high.
To compare the technique of suction aspiration using a disposable syringe and an ordinary 40 mm long 18 gauge needle (internal diameter 1.27 mm), with Vim-Silverman's needle in obtaining liver tissue in patients with liver disease of various etiology.
Liver biopsy was performed in 60 patients each using either technique. The size of the biopsy tissue obtained and the number of times a diagnosis was reached with the two techniques were compared.
The mean size of tissue obtained by suction aspiration (11.2 mm) was greater than that by the Vim-Silverman technique (6.3 mm) (p = 0.001). The tissue sample was inadequate for opinion in 3 patients in the aspiration group and in 10 patients in the Vim-Silverman group (p = ns).
Suction aspiration liver biopsy can be done satisfactorily using disposable syringe and 18 gauge needle.
传统的和一次性的肝活检针价格昂贵，在需要进行肝活检的肝病患病率较高的发展中国家会增加经济负担。
比较使用一次性注射器和普通的40毫米长18号针（内径1.27毫米）进行抽吸活检的技术与Vim-Silverman针在获取各种病因肝病患者肝组织方面的情况。
对60例患者分别采用两种技术进行肝活检。比较两种技术所获取活检组织的大小以及得出诊断结果的次数。
抽吸活检所获取组织的平均大小（11.2毫米）大于Vim-Silverman技术所获取组织的平均大小（6.3毫米）（p = 0.001）。抽吸组有3例患者的组织样本不足以做出诊断，Vim-Silverman组有10例患者的组织样本不足以做出诊断（p =无显著性差异）。
使用一次性注射器和18号针进行抽吸式肝活检可以取得令人满意的效果。
