超声造影引导下经皮腹膜后占位性病变穿刺活检的价值

The value of contrast-enhanced ultrasound-guided biopsy in retroperitoneal puncture

目的:探讨超声造影(contrast-enhanced ultrasound,CEUS)引导下经皮腹膜后占位性病变穿刺活检的价值。方法:收集80例拟行CEUS引导下经皮腹膜后占位性病变穿刺活检的患者,分析坏死显示情况、穿刺次数、取材满意率、病理诊断率和并发症。结果:3例因病灶内始终未见增强取消穿刺,其余77例均接受穿刺活检,常规超声和CEUS在该组患者病灶内部坏死区域的显示率分别为15.0%和62.5%,差异有统计学意义(P<0.05)。取材满意率为100.0%(77/77),病理诊断率为100.0%(77/77),根据病理学检查结果制定治疗方案,所有患者无严重并发症发生。结论:CEUS较常规超声更清晰地显示腹膜后病灶的范围及坏死区域,用以引导穿刺活检,能有效地取材并获得准确的病理学诊断结果。

Objective:To evaluate the value of contrast-enhanced ultrasound(CEUS)-guided retroperitoneal puncture biopsy.Methods:Collected 80 patients who were planned to receive CEUS-guided percutaneous biopsy for retroperitoneal tumor.The interior necrosis,puncture number,the sampling satisfaction rate,pathological diagnosis rate and complications were analyzed.Results:The puncture was cancelled in 3 cases because there was no enhancement in the whole lesion.In the remanent 77 patients,the display rate of the interior necrotic area was 15.0%and 62.5%by conventional ultrasound and CEUS,respectively.The difference was statistically significant(P<0.05).The sampling satisfaction rate was 100.0%(77/77),and the pathological diagnosis rate was 100.0%(77/77).Treatment plan was made according to pathological results.No serious complication occurred in all cases.Conclusion:CEUS can show the range of retroperitoneal lesions and necrotic areas more clearly than ultrasound.The method can effectively draw materials and obtain accurate pathological diagnosis.
