超声引导下穿刺活检在腹膜后病变中的应用价值

目的：探讨超声引导下经皮穿刺活检在腹膜后病变中的临床应用价值并总结部分腹膜后肿物超声声像学特征。方法对2009年9月-2013年4月来我科就诊的47例腹膜后病变患者行超声引导下经皮穿刺活检，以所取组织能够作出明确病理诊断为取材满意，随访≥6个月，以术后病理诊断或随访影像学、化验等检查结果为最终临床诊断并观察有无并发症。结果本组47例均成功获取组织标本，穿刺成功率100%，其中44例明确了病理学诊断，定性诊断率93.6%（44/47）。穿刺定性诊断符合率100%（44/44）。穿刺活检敏感度、特异度及准确率分别为97.4%、100%及97.9%。47例穿刺患者均无并发症发生。部分腹膜后肿物具有特征性声像图表现。结论超声引导下经皮穿刺活检腹膜后病变准确性高，并发症少，可为临床诊断及治疗提供参考。

Application of ultrasound-guided biopsy in diagnosis of retroperitoneal diseases

Objective To study the application of ultrasound-guided biopsy in diagnosis of retroperitoneal diseases and summarize the ultrasonographic features of retroperitoneal tumors. Methods Forty-seven patients with retroperitoneal diseases who underwent ultrasound-guided biopsy in our department from September 2009 to April 2013 were included in this study. They were followed up for months, during which they were finally diagnosed with retroperitoneal diseases according to their pathological examination, imaging data and laboratory findings. Their complications were observed. Results The success biopsy rate was 100%. Of the 47 patients, 44 were diagnosed with retroperitoneal diseases by histopathology with a qualitative diagnostic rate of 93.6% （44/47） and qualitative biopsy diagnosis rate of 100%（44/44）. The sensitivity, specificity and accuracy of biopsy were 97.4%, 100%and 97.9%, respectively. No complication occurred in the patients after biopsy. Some retroperitoneal tumors showed characteristic ultrasound images. Conclusion The accuracy of ultrasound-guided biopsy is high in diagnosis of retroperitoneal diseases with few complications and can thus be used in their clinical diagnosis and treatment.
