目的 对其他检查方法不能作出定性诊断的中心型肺肿瘤进行超声引导穿刺活检 ,探讨该方法对中心型肺肿瘤的诊断价值。方法 通过实变肺行超声检查确认肿瘤 ,并设定穿刺线路。采用 2 1G日产八光手动负压穿刺针摄取组织 ,3 .0cm以上的肿瘤同时加用美国Bard自动活检枪及 2 1G细针活检 ;针腔内残留液均做细胞学检查。结果 5 2例接受穿刺者组织学检查诊断正确率为 71.2 % ( 37例 ) ,细胞学检查诊断正确率为 6 9.2 %( 36例 ) ,二种方法互补诊断正确率达 84.6 % ( 4 4例 ) ,组织定性诊断率达 80 .8% ( 4 2例 )。并发症 7例 ( 13 .5 % ) ,其中气胸 2例 ,咳血痰 5例 ( 10 % ) ,无严重并发症发生。结论 超声引导细针穿刺活检对肺中心型肿瘤的定性诊断 ,为确定治疗方案提供了依据 ,有较高临床应用价值。但中心型小肿瘤的超声显示和确认仍为穿刺活检的首要条件 ,应予以重视
Objective To conduct ultrasound-guided biopsy of central lung tumors that cannot be qualitatively diagnosed by other examination methods, and to explore the diagnostic value of this method for central lung tumors. Methods Tumors were confirmed by ultrasound of consolidation lungs and puncture lines were set. Using 21G Nissan eight light manual negative pressure puncture needle to ingest tissue, more than 3. 0cm tumor at the same time using the United States Bard automatic biopsy gun and 21G fine needle biopsy; needle cavity residual fluid were used for cytological examination. Results The diagnostic accuracy rate of histological examination of 52 cases was 71. 2% (37 cases). The correct rate of cytology was 6 9.2% (36 cases). The correct rate of complementary diagnosis of the two methods was 84.6% (44 cases). ), the organization of qualitative diagnostic rate of 80.8% (42 cases). Seven patients (13.5%) had complications, including 2 cases of pneumothorax, 5 cases of hemoptysis (10%), and no serious complications. Conclusion Ultrasound-guided fine-needle aspiration biopsy for the qualitative diagnosis of lung-centered tumor provides a basis for the determination of the treatment plan and has a high clinical value. However, the ultrasound display and confirmation of central small tumors are still the primary condition for biopsy and should be considered
