目的应用和比较不同穿刺针、不同导引技术对穿刺活检结果的影响。材料和方法90例中男性63例,女性27例,平均年龄54岁(23-78岁),胸部66例,腹部24例;按穿刺针不同分DFBN(dispos able fanseen biopsy needle)和ADGSTN(automatic disposable guillotine soft tissue needle)两组;比较两组的诊断正确率、并发症发生情况。结果所有病例均穿刺成功并获得细胞学和/或组织学材料,细胞学检查正确者9/25例(36%),组织学检查正确者66/91例(72.53%),DFBN和ADGSTN两种穿刺针在标本的大小和完整性、病理学结果、诊断正确率(55.81%/91.30%)有差异(P<0.01),穿刺活检在肿瘤患者中的诊断正确率为78.95%,发生并发症8例(8.89%),其中气胸2例,咯血或痰中带血6例。结论CT/US 导引经皮细针穿刺活检是一项先进的影像学与病理学活检相结合的技术,对于胸腹内不明原因的占位性病变,尤其是怀疑肿瘤者是一项简便易行、较安全的诊断手段。ADGSTN较DFBN材料满意且诊断正确率高。 相似文献

The diagnostic value of virtual colonoscopy versus colonoscopy was compared in detection of colorectal neoplasia. Virtual
colonoscopy was performed on 29 patients with suspected colorectal diseases, Results were compared with colonoscopy for each
case. Virtual colonoscopy was successfully performed on each patient. All patients tolerated virtual colonoscopy well, had
no complications. All colorectal malignance were identified both by virtual colonoscopy and colonoscopy. Twenty-five polyps
were detected with colonoscopy, whereas only 16 polyps were defined by virtual colonoscopy. Detection rates of polyps greater
than 1.0 cm, between 0.5–0.9 cm and less than 0.5 cm in size were 90%, 62.5% and 28.6% respectively. Virtual colonoscopy is
fast, minimally invasive and well tolerated. This technique is a valuable clinical method in diagnosis of colorectal malignance
and polyps larger than 0.5 cm in size. 相似文献
