OBJECTIVE
To assess the value of a new short biopsy needle modified from the Parker-Pearson needle in obtaining adequate synovial tissue from small joints.
METHODS
The short needle is 2.5 cm in length with a repositioned hooked biopsy notch closer to the end of the needle to allow better specimen retrieval. It can be used to obtain synovial biopsies from small joints of the hand using the usual arthrocentesis approaches.
RESULTS
Ten patients underwent 12 synovial biopsies with a success rate of 92%. No complications from the procedure were observed. Samples obtained were adequate for a variety of studies including synovial histopathological evaluation, electron microscopy, and DNA extraction.
CONCLUSION
The new modified short needle expands the spectrum of joints that can be biopsied for diagnostic and research purposes in an outpatient setting.
目的
评估一种由帕克-皮尔森针改良而来的新型短活检针在从小关节获取足够滑膜组织方面的价值。
方法
该短针长2.5厘米，其带钩活检切口重新定位，更靠近针的末端，以便更好地获取标本。它可用于通过常规关节穿刺方法从手部小关节获取滑膜活检样本。
结果
10例患者接受了12次滑膜活检，成功率为92%。未观察到该操作的并发症。所获取的样本足以用于包括滑膜组织病理学评估、电子显微镜检查和DNA提取在内的各种研究。
结论
这种新型改良短针拓宽了可在门诊环境下进行活检以用于诊断和研究目的的关节范围。
