螺旋刃活检针在骨肿瘤诊断中的应用价值

目的:探讨螺旋刃活检针在骨肿瘤诊断中的应用价值.方法:应用螺旋刃活检针进行四肢、脊柱及骨盆骨肿瘤穿刺活检共94例(恶性肿瘤59例、非恶性肿瘤35例),其中B超引导下穿刺45例,CT引导下穿刺2例.结果:组织获取率达98.9%;88例可做出病理诊断,阳性率93.6%.诊断恶性骨肿瘤的敏感性为93%,特异性100%,阳性预测值100%,阴性预测值89.7%.结论:该活检针结构设计独特合理,标本挤压损伤小,在单一针道内可完成不同深度或多点取材,值得推广应用.

Application value of spiral - edged biopsy needle in diagnosing bone tumors

purpose: To investigate the application value of sprial - edged biopsy needle in diagnosing bone tumors. Methods: Bone tumor puncture biopsy was performed with sprial - edged biopsy needle for 94 cases suspected to have tumors at limbs, spine and pelvis (59 malignant and 35 benign). Of the all cases, B - ultrasound - guided and CT - guided puncture biopsy was 45 cases and 2 cases respectively. Results:Tissue-obtained rate was 98.9% and the positive rate was 93.6% . In diagnosing malignant bone tu-mors, the sensitivity was 93% and the specificity was 100%, predictive value was 100% for positive and 89,7% for negative. Con-clusions:The specimen from different depth and areas could been obtained through a single puncture tract with this kind of needle and the squeezing injury to specimen is slight. The design of this instrument is special and reasonable. It is worth extended application.
