摘　　要：目的:观察和评价分析大孔径CT模拟机引导下经皮穿刺肺活检的临床价值。方法:搜集2011年1月至2014年6月梧州市红十字会医院行普通CT经皮穿刺肺活检的52例患者资料(A组),搜集2014年7月至2018年10月应用大孔径CT模拟机引导下肺穿刺活检的116例患者资料(B组),对两组患者检测的确诊率及并发症发生率进行比较分析。结果:两组穿刺组织标本均送病理检查,显示两组确诊率无显著性差异(P>0.05)。两组一次成功率具有明显差异(53.4%vs76.7%, P<0.05)。两组患者的并发症发生率无统计学意义(23.1%vs 27.6%, P>0.05)。结论:通过对比普通诊断CT机和大孔径CT模拟机引导下进行经皮穿刺肺活检术,两者对疾病的确诊率均较高,并发症发生率不高,且均没有发生致命性严重并发症。同时大孔径CT模拟机具有孔径大、适合肥胖患者检查、模具应用及定位精准等明显优势,是值得推广的穿刺引导方法。Objective To observe and evaluate the clinical value of percutaneous lung biopsy guided by large-aperture CT simulator.Methods The clinical data of 52 patients receiving conventional CT-guided percutaneous lung biopsy in Wuzhou Red Cross Hospital from January 2011 to June 2014(group A), and those of 116 patients who underwent lung biopsy guided by large-aperture CT simulator from July 2014 to October 2018(group B) were collected in this study. The diagnostic rates and complication rates of two groups were retrospectively analyzed and compared. Results The biopsy specimens from both groups were sent for pathological examination, and the results showed that there was no significant difference in the diagnosis rate between two groups(P>0.05). The first-attempt success rate for percutaneous lung biopsy in group A and B was 53.4% and 76.7%, respectively, with statistical differences(P<0.05). The complication rates in the two groups were similar, without statistical differences(23.1% vs27.6%, P>0.05). Conclusion Both of conventional CT-guided percutaneous lung biopsy and percutaneous lung biopsy guided by large-aperture CT simulator are considered to have high diagnostic rate and low incidence of complications, without fatal complications. Moreover, large-aperture CT simulator can realize accurate positioning and fixation with vacuum mould, and is suitable for the examination of obese patients because of its large apertures. Percutaneous lung biopsy guided by large-aperture CT simulator is worthy of popularization.
