摘要
目的:探讨应用18G和20G自动切割针行CT导向下经皮肝穿刺活检的诊断效率和并发症的差异。方法:对比分析296例肝内占位性病变的患者,随机选择18G或20G自动切割针行肝组织活检,其中18G组142例,20G组154例,对比分析使用这2种型号穿刺针的诊断效率和并发症。结果:18G组肝癌114例,穿刺确诊111例,确诊率97.37%。假阴性3例,假阴性率2.63%;良性病变28例,确诊28例。20G组肝癌122例,穿刺确诊116例,确诊率95.08%,假阴性6例,假阴性率4.92%;良性病变32例,确诊32例。穿刺后出现肝区疼痛,其中18G组19例,20G组11例,未予特殊处理。2组在确诊率、假阴性率、疼痛发生率间的差异均无显著性意义(P>0.05)。结论:18G和20G自动切割针在CT导向下经皮肝穿刺活检时对肝脏病变的确诊率、假阴性率及术后疼痛发生率等方面均无显著差异。
Objiective：To evaluate the difference of diagnostic efficacy and complications between the usage of 18 and 20 gauge （G） core needles in CT guided perscutaneous liver biopsies. Methods： Percutaneous liver biopsies were performed using 18G （group A） core needles in 142 cases and 20G （group B） core needles in 154 cases respectively. Their diagnostic efficacy and complications were correlatively compared. Results：In group A, 111 of the 114 patients with liver cancer were accurately diagnosed by biopsy （97.37%） and false negative happened in the other 3 cases （2.63 % ）. 28 patients in group A with benign lesions were diagnosed by biopsy as well. In group 13,116 of the 122 patients with liver cancer were diagnosed by biopsy （95.08%） and the other 6 cases were misdiagnosed as false negative （4.92%）. 32 patients in group B with benign lesions were accurately diagnosed by biopsy. Post-biopsy focal hepatalgia without the need of special treatment was encountered in 19 cases of group A and 11 cases of group B. The difference between group A and group B in diagnostic accuracy rate, false negative rate and focal hepatalgia rate all revealed no statistical significance. Conclusion：The diagnostic accura- cy rate, false negative rate and hepatalgia rate showed no significant differences between the two groups （group A and B） in which 18G and 20G core needles were respectively used for liver biopsy.
