ABSTRACT
Needle tract tumor cell seeding (NTTCS) with use of automatic and manual bisopsy (14G,20G) for excised hepatic carcionma were studied and the literatures were reviewed. The results showed that;(1)The number of NTTCS was increased with needle－diameter （α＝0.05～0.001） besides manual needle aspiration biopsy;(2)The number of NTTCS by manual fine－needle cutting biopsy （α=0.9）;(3)The number of NTTCS by use of automatic bisopsy (14G,20G) was fewer than that by manual biopsy （α＝0.05～0.001）.It is considered that automatic biopsy may NTTCS and needle biopsy had a relative safety.
Key words：tumor;biopsy;needle tract seeding
介入性超声在临床医学中已日益发挥重要作用[1]。自动组织学活检技术是近年来介入性超声重要技术革新[2]。穿刺活检是否能导致肿瘤播散已受到广泛关注[3]。有关自动和手动组织学活检针道恶性细胞种植的实验研究国内外尚未见报道。本文旨在探讨不同针径手动切割、抽吸与自动组织学活检是否影响针道恶性细胞种植，并结合文献复习探讨有关肿瘤活检引起播散的安全性问题。 |
