同轴技术在150例超声引导肝脏穿刺活检中的应用

Application of ultrasound-guided percutaneous co-axial technique in liver tumor biopsy of 150 patients from 2015 to 2016

目的评价超声引导下同轴技术在肝脏穿刺活检中的临床应用价值。方法收集2015年3月至2016年12月在四川大学华西医院采用超声引导下同轴技术行肝脏穿刺活检患者的临床资料，回顾性分析穿刺成功率、取样次数、病理检查诊断率、穿刺后并发症发生率等指标。结果共纳入150例患者，包括男性99例，女性51例，平均年龄54．9±4．5岁，疑似肿瘤大小平均2．4±1．2cm。超声引导下穿刺肝脏组织的成功率100％（150／150），平均取样次数为2．4±0．6次，病理检查确诊率100％（150／150）。穿刺后并发症包括局部轻度疼痛（37％，56／150）和出血（0．7％，1／150）。结论超声引导下同轴针肝脏穿刺活检，可多次、多点取材，且并发症较轻，是一项安全、有效、简便易行的影像引导下穿刺活检技术。

Objective To evaluate the clinical value of ultrasound-guided percutaneous co-axial technique in liver tumor biopsy. Methods The clinical data of patients who received ultrasound-guided percutaneous co-axial liver tumor biopsy from March 2015 to December 2016 in West China Hospital of Sichuan University were collected to retrospectively analyze the outcomes of biopsy success rate, sampling number, pathology diagnostic rate and incidence of complications. Results A total of 150 patients involving 99 males and 51 females were included, with a mean age of 54.9±4.5 years. The mean tumor size was 2.4±1.2cm. The ultrasound-guided liver tumors biopsy success rate was 100% （150/150）. The mean sampling frequency was 2.4±0.6 times. Complications after biopsy included mild local pain （37%, 56/150） and bleeding （0.7%, 1/150）. Conclusion Ultrasound-guided co-axial biopsy is an simple, safe and efficient image-guided biopsy technique which allows multiple sample acquisitionand reduces complications.
