骨肿瘤经皮套管针穿刺活检

[目的]报告171例穿刺活检的结果并探讨相关影响因素。[方法]采用套管活检针对骨肿瘤进行术前穿刺活检，回顾分析171例骨肿瘤患者的穿刺活检的结果。[结果]171例，穿刺活检阳性155例，穿刺活检阳性率90．64％，行手术治疗获得大体标本病理诊断者122例，活检准确诊断者98例，准确率80．33％，误诊5例。恶性肿瘤总例数110例，穿刺活检敏感性95．41％，特异性100％。[结论]穿刺活检对骨肿瘤术前诊断有较大价值，实施者对骨肿瘤的认识水平，操作的细致程度，对活检阳性率、准确率及并发症的发生有重要影响。

Percutaneous biopsy of bone tumor: reports of 171 cases

[Objective] To report the result of percutaneous biopsy in bone tumor and analyze the interrelated influence factors. [Method] A total of 171 patients were subjected to trocar puncture for biopsy of bone tumor in pre-operation, and the results of all cases were reviewed. [Result] Totally 155 cases in 171 cases showed positive outcome, the positive rate was 90.64%. The accuracy of 98 cases was comfirmed in 122 postoperative pathology diagnoses, and the acuracy rate was 80.33%. There were 110 cases of tumor. Biopsy sensitivity was 95.41%, and biopsy diagnostic particularity was 100%. [Conclusion] Percutaneous biopsy is both effective and valuable for the diagnosis of bone tumor in pre-operation, but the biopsy positive rate and accuracy, and postoperative complication was highly related to the operator cognitive level of bone tumor and meticulous manipulation and so on.
