彩超引导下腹膜后实性肿物粗活检针穿刺的临床应用

Diagnostic value of coarse needle biopsy in retroperitoneal solid mass guided by color ultrasound

目的探讨彩超引导下腹膜后实性肿物粗活检针穿刺的临床应用价值。方法32例腹膜后实性肿物在彩超引导下行粗活检针穿刺组织学活检，并与术后病理诊断结果相比较。结果32例均穿刺成功，无并发症。与手术后病理诊断比较，穿刺活检的诊断总符合率为93．75％（30／32）。穿刺活检对恶性肿瘤无假阴性诊断，假阳性诊断率为3．13％（1／32）。结论超声引导下对腹膜后实性肿物行粗活检针穿刺组织学活检是一种并发症少、确诊率高的诊断方法。

Objective To evaluate the clinical value of color ultrasound guided coarse needle bioptic histopathology in the diagnosis of retroperitoneal solid mass. Methods 32 cases with retroperitoneal solid mass accepted coarse needle biopsy （CNB） guided by color ultrasound, and followed to surgical mass resection. The histopathological result of CNB was compared to the post-operative pathological diagnosis. Results CNB were successful in all cases and no complications occurred. Compared with the post-operative pathology, the accuracy of CNB was 93.75% （30/32）. There was no false-negative and very low rate of false-positive （3.13% ,1/32） of CNB in diagnosing malignant tumor. Conclusions CNB guided by color ultrasound is a safe and an effective method in diagnosis of retroperitoneal solid mass.
