摘要
本文报道110例颈、胸、腹部多种病变和肿瘤超声引导自动活检术(活检枪和18～20 G针)的成功经验,另将一组慢性肾病超声引导手动Tru Cut粗针(14 G)活检30例与30例自动活检组(Biopty 18 G)作对照研究。结果表明:1.自动活检装置可广泛应用于胸腹部多种内脏和前列隙、乳腺等小器官的病变和肿瘤的组织学穿刺活检,对于那些活检难度较大的脏器或病变尤为适用。2.本组100例取材成功率高达100%,而且活检标本量和质均提高,标本满意足以作出组织学诊断者达97.2%。3.慢性肾病自动活检成功率、标本长度均优于手动活检,且并发症明显减少(P<0.01)。尽管18 G针自动活检标本所含肾小球数与手动14 G粗针活检并无明显区別(P>0.9),但笔者认为;超声引导自动活检术简便、安全、准确、迅速,值得推广使用。
One hundred and ten biopsies of various lesions or tumors in the liver, gallbladder, kidney, prostate, lung, retroperitoneal space, intestine, etc. were performed with automatic biopsy gun under the guidance of ultrasound and 18G or 20G needles. Out of them, thirty cases of automatic renal biopsies (18G, Biopty) were prospectively compared with thirty cases of manual ones (14G, Tru-Cut) to assess the clinical effectiveness of this new method. Our results showed: Ⅰ. Biopsy samples sufficient for histologic analysis were obtained in all of the 110 cases(100%), histo pathologic speciments with high quality accounted for 97.2%. 2. Sampling success rate and the length of specimens obtained with automatic renal biopsy technique (18G Biopty) had advantages over 14G Tru Cut manual renal biopsy technique (P<0.01). However, the complications after biopsy were signicantly lower than those of manual renal biopsy group (P<0.01). The average number of glomeruli in tissue specimens had no difference between the two techniques (P>0.9). The authors concluded that US guided automatic biopsy is a simple, safe and valuable diagnostic tool, and could be recommended for further wide use clinically.
