Fine cutting needles for histology are now widely used in echo-guided biopsies of various organs. In this study we compared the results obtained in the biopsy of neoplastic hepatic lesions using two different 21-gauge cutting needles: Trucut needle (Urocut) and a modified Menghini needle (Surecut). Eighty-five patients with primary or metastatic hepatic neoplasms were biopsied with a Urocut needle and a further 85 patients underwent biopsy with a Surecut needle. The two groups were comparable for size and nature of hepatic neoplasms. The Urocut needle provided a much higher percentage of diagnostic material than the Surecut needle (94.8% vs 70.5%) regardless of the primary or metastatic nature of the lesion or its size. The diagnostic accuracy was only identical for both needles (91.3% for Urocut vs 91.5% for Surecut) whenever the diagnostic material was compared in cases in which both types of needles had been used to take the biopsy specimens. There were no complications in either of the two groups studied. Given the smaller incidence of non-diagnostic biopsies with the Urocut needle, we consider that this needle should be preferred in echo-guided biopsies of neoplastic hepatic lesions.
组织学用的细切割针目前广泛应用于各种器官的超声引导活检。在本研究中，我们比较了使用两种不同的21号切割针：Trucut针（Urocut）和改良的Menghini针（Surecut）对肝脏肿瘤性病变进行活检的结果。85例原发性或转移性肝脏肿瘤患者用Urocut针进行活检，另外85例患者用Surecut针进行活检。两组在肝脏肿瘤的大小和性质方面具有可比性。无论病变是原发性还是转移性，也无论其大小，Urocut针提供的诊断材料百分比都比Surecut针高得多（94.8%对70.5%）。每当比较两种针都用于获取活检标本的病例中的诊断材料时，两种针的诊断准确性才相同（Urocut针为91.3%，Surecut针为91.5%）。在研究的两组中均未出现并发症。鉴于Urocut针导致非诊断性活检的发生率较低，我们认为在肝脏肿瘤性病变的超声引导活检中应首选这种针。
