摘要
目的 比较粗针(18G)、细针(21G)超声引导下经皮穿刺组织活检的临床应用价值。方法用粗针及细针于超声引导下经皮穿刺组织活检共1302例患者。所取组织能作出明确组织病理诊断者为取材满意,否则为不满意。以术后病理诊断或随访6个月的结果为最后诊断。结果 粗针活检455例,平均进针2.2次/例,细针847例,平均进针2.8次/例。同一部位取材满意率粗、细针间无显著性差异(P>0.05),细针后腹膜、肺及胸膜取材满意率低于其他脏器。粗、细针间诊断的敏感性、特异性、准确性及并发症发生率均无显著性差异。结论 超声引导下粗针穿刺组织活检同细针一样安全,并且所取标本较大、较完整,有利于病理科处理和组织学分型,值得在临床推广应用。
Objective To assess the clinical usefulness of US guided percutaneous biopsy by core(18 G) and fine(21 G) guage cutting needle.Methods US guided biopsy were performed in 1302 patients.A biopsy was considered successful if a specific benign or malignant diagnosis was rendered by the pathologist.The final diagnosis was the pathological diagnosis or the result of follow up 6 months.Results All biopsies were performed with a core 18 G (455 cases,a mean 2.2 needle passes) or fine 21 G (847 cases,a mean 2.8 needle passes) cutting needles.The successful rates sampling in the same tissue,sensitivity,specificity and accuracy for the diagnosing had no significant difference between 18 G and 21 G needles(P> 0.05 ).The complications rates were 1.7 % and 1.3 % in 18 G and 21 G needle, respectively(P> 0.05 ).Conclusions The US guided biopsy with 18 G needle is as safe as those with 21 G needle and require fewer needle passes to obtain a usable sample which is suitable for pathology diagnosis.
