虚拟支气管镜导航在肺周围型病变中的诊断价值*

Diagnostic value of VBN for peripheral pulmonary lesions*

摘要:

目的??探讨虚拟支气管镜导航（VBN）在肺周围型病变中的诊断价值。方法?纳入2014年6月－2015年6月唐都医院呼吸科就诊的肺周围型病变200例（0.8 cm<直径<4.0 cm），分为VBN组和对照组。VBN组：VBN引导超细支气管镜到达目标支气管，对照组：超细支气管镜仅以胸部CT为引导到达目标支气管。结果?200例患者中，VBN组及对照组诊断率差异无统计学意义（χ2=3.31，P =0.069）；VBN组及对照组直径>2.0 cm和≤2.0 cm的诊断率均差异有统计学意义（χ2=13.45、5.31，P =0.000、0.021）；两组活检工具到达病变的平均时间差异有统计学意义（P =0.047），检查总时间差异无统计学意义（P =0.230），不良并发症差异无统计学意义（P =0.960）。结论?VBN未提高肺周围型病变的诊断率，但缩短了定位病变时间。

Abstract:

Objective?To explore the diagnostic value of virtual bronchoscopic navigation (VBN) for peripheral pulmonary lesions.?Methods?200 cases with peripheral pulmonary lesions (0.8 cm < diameter < 4.0 cm) were divided into VBN and control group from June 2014 to June 2015. VBN group: VBN guided ultrafine bronchoscope to the target bronchus, control group: ultrafine bronchoscopy with chest CT as a reference guided to the target bronchus.?Results?There were no significant differences in the diagnosis rates between VBN group and control group in 200 patients (χ2 = 3.31, P = 0.069); But, the diagnosis rates with diameter more than 2.0 cm and less than or equal to 2.0 cm had statistically significant differences of VBN group and control group (χ2 = 13.45, 5.31, P = 0.000, 0.021, respectively); We also found that the mean time of biopsy tool reach to the lesions had significant differences between the two groups (P = 0.047). There were no significant differences in total checking time and complications (P = 0.230, 0.960, respectively).?Conclusions?Virtual bronchoscopic navigation did not improve the diagnosis rate of pulmonary peripheral lesions, but shortened the time to locate the lesions.
