目的 探讨超声引导下肝脓肿置管引流及腔内注药治疗的方法及意义。方法 选择2016年3月至2018年3月来我院就诊 的47例肝脓肿患者，进行超声引导下肝脓肿置管引流，并腔内注射5%甲硝唑溶液反复冲洗。结果 经超声介入置管 及腔内注药治疗后临床症状均消失，脓腔小于20mm。6个月随访后，脓腔均消失。结论 超声引导下肝脓肿置管并腔 内注药冲洗效果显著，创伤小，明显缩短了患者的病程。

Objective to investigate the method and significance of ultrasound-guided catheter drainage and intravitary drug injection in the treatment of hepatic abscess. Methods 47 patients with hepatic abscess admitted to our hospital from March 2016 to March 2018 were selected for ultrasound-guided catheterization and drainage of hepatic abscess, and intravitary injection of 5% metronidazole solution was repeatedly rinsed. Results the clinical symptoms disappeared and the abscess cavity was less than 20mm. The abscess cavity disappeared after 6 months of follow-up. Conclusion ultrasound-guided catheterization and intracavitary injection irrigation for hepatic abscess has significant effect, less trauma and significantly shortened the course of the disease.
