B超引导与X线引导胸内肿块细针吸取细胞学检查的对比分析(附108例报告)

Comparison of Fine Needle Aspiration Biopsy for Intrathoracic Mass Guided by Utrasonography and X-ray. A Report of 108 Cases

本文报告B超引导与X线引导胸内肿块细针吸取细胞学检查108例(122次),B超组54例(59次).细胞学阳性46例,阳性率为85.50％,其中恶性肿瘤35例,良性病变11例;X线组54例(63次),细胞学阳性47例,阳性率87.03％,其中恶性肿瘤35例,良性病变12例.两组比较差异无显著性(P>0.05)由于两组引导物理特性不同,肿块生长部位各异,不同的穿刺部位阳性率亦有高低.B超组在胸水内区肿块穿刺阳性率比X线组高(P<0.01),而X线组在脊柱旁区穿刺阳性率比B超组高(P<0.05).

The results of fine-needle aspiration cytologic examination in the diagnosis of intrathoracic mass under the guidance of real-time ultrasonography (group A,54 cases)and X-ray(group B,54 cases)were analysed. Positive rate in group A was 85. 50%,in which there were 35 malignant tumors and 11 benign lesions. Positive rate in group B was 87. 03% in which there were 35 malignant tumors and 12 benign lesions. Statistical management showed no difference (P>0. 05) between the two groups. The positivity varied,however, with location of the masses as well as puncture site. For instance, positivity in Group A was higher than that of group B when the mass was submerged in effusion (P< 0. 01)and contrarily it was higher in group B when the mass was situated nearby the spinal column(P<0. 05).
