肺深部病变穿刺活检中两种不同活检枪的比较研究

Percutaneous puncture biopsy of deep pulmonary lesions: a comparative study of two different biopsy guns

目的研究同轴套管型自动活检枪在肺深部病变穿刺活检中的应用价值。方法144例肺深部病变穿刺病例,根据所用器械不同分为两组,其中A组83例采用同轴套管型自动活检枪,B组61例采用普通自动活检枪。统计每组的活检阳性率、诊断准确率、气胸发生率及针道出血发生率,对两组数据进行比较分析。结果两组比较在活检阳性率及诊断准确率上无显著性差异,在气胸及针道出血的发生率上A组较B组明显降低,两组比较差异有统计学意义(P<0.05)。结论在肺深部病变的穿刺活检中,采用同轴套管型自动活检枪不影响活检阳性率及诊断准确率,且较之采用普通自动活检枪更安全、更方便,值得临床推广。

Objective To discuss the clinical application of the automated biopsy gun with a detachable coaxial cutting needle in performing percutaneous puncture biopsy of deep pulmonary lesions. Methods Of 144 patients who underwent percutaneous puncture biopsy for deep pulmonary lesions, coaxial automated biopsy gun was adopted in 83 (group A) and common biopsy gun in 61 (group B). The positive rate of biopsy, the accuracy of diagnosis and the occurrence of both pneumothorax and needle-track bleeding were calculated.
