摘　　要：目的:探讨同轴穿刺针在腹部病变活检中的应用价值。方法:应用17G或19G同轴穿刺针对40例腹部疾病患者41个病灶在CT导向下进行穿刺活检,病灶位于肝脏(n=13)、腹膜后(n=24)、腹腔(n=2)、盆腔(n=2),病灶大小为1.0 cm×1.0 cm^10.1 cm×12.3 cm。结果:40例41个病灶均成功进行了穿刺活检及细胞学检查,40个进行了病理检查。经手术证实和临床随访观察,活检病理诊断符合率为90.0%(36/40),其中恶性病变的诊断符合率为92%(23/25),良性病变的诊断符合率为86.7%(13/15)。所有病例均无严重并发症发生。结论:CT导引下同轴穿刺针穿刺活检是腹部病变的一种简单、安全、准确的诊断方法。Objective：To evaluate the clinical application of coaxial core biopsy needle in CT-guided percutaneous abdominal biopsy. Methods： CT-guided coaxial core needle biopsy was performed in 41 lesions in 40 patients of abdominal diseases. The lesions located in liver （ n = 13）, retroperitoneum （ n= 24）, abdominal cavity （ n = 2）, pelvis （n = 2）. The sizes of the lesions ranged from 1.0cm×1.0cm to 10. 1cm×12. 3cm. Results：Successful biopsies were achieved in all 41 lesions. Cytological and pathological examinations were performed in 41 and 40 lesions respectively. As compared with the results of surgery and clinical followup, the diagnostic accuracy of pathological examinations was 92 % （23/25） for malignant lesions, 86.7% （13/15） for benign lesions,with a total accuracy of 90. 0% （36/40）. No severe complications were happened in all patients. Conclusion：CT-guided percutaneous biopsy with coaxial core biopsy needle is a simple, safe and accurate method for diagnosis of abdominal diseases.
