摘要
目的:探讨支气管超声导向鞘(EBUS-GS)技术联合Directpath虚拟导航及冷冻肺活检在肺外周结节诊断中的应用效果。方法:选取187例经胸部CT检查显示肺外周结节的患者临床资料,依据检查方法的不同进行分组,将行支气管内超声引导鞘经肺活检术(EBUS-GS-TBLB)检测的患者纳入EGT组(102例);采用支气管镜导向鞘联合Directpath虚拟导航及冷冻肺活检(EBUS-GS-Directpath-TBCB)患者纳入EGDT组(85例)。比较分析两组患者的临床资料、诊断结果以及不同肺结节大小的可视率。结果:两组患者在病变发现情况、诊断阳性率、检查总用时以及并发症的发生方面相比,差异均无统计学意义,而EGDT组EBUS定位病灶时间较EGT组明显缩短,差异有统计学意义(t=2.015,P<0.05);EGDT组8~20 mm肺结节的可视率明显高于EGT组,差异有统计学意义(x^2=7.745,P<0.05);两组不同大小肺结节的诊断率相比,差异无统计学意义。结论:EBUS-GS联合Directpath虚拟导航诊断,可提高对8~20 mm肺结节的可视率,缩短病灶定位时间,有利于提高临床检查效率。
Objective: To explore the application effect that endobronchial ultrasound-guided sheath(EBUS-GS) combined with Directpath virtual navigation and frozen lung biopsy in diagnosis of peripheral pulmonary nodule. Methods: The clinical data of 187 patients with peripheral pulmonary nodules by chest computed tomography(CT) examination were selected, and they were divided into different group according to different examination methods. The patients who underwent EBUS-GS transpulmonary lung biopsy(EBUS-GS-TBLB) were included in the EGT group(102 cases), and patients who underwent bronchoscope-guided sheath with Directpath virtual navigation and frozen lung biopsy(EBUS-Gs-DirectPath-TBCB) were included in the EGDT group(85 cases). And then, the clinical data, diagnostic results and the visual rate of pulmonary nodules with different size of two groups were compared and analyzed. Results: There were no statistically significant differences between the two groups in terms of the detected situation of lesion, diagnostically positive rate, total examination time and the occurrence of complication, while the EBUS localization time on lesions of EGDT group was significantly shorter than that of EGT group(t=2.015, P<0.05). The visual rate of pulmonary nodules with 8~20 mm of EGDT group was significantly higher than that of EGT group(x^2=7.745, P<0.05). The difference of diagnostic rate of pulmonary nodules with different size between the two groups was no significant. Conclusion: The virtual navigation diagnosis that EBUSGS combines with Directpath can improve the visual rate pulmonary nodules with 8 ~ 20 mm, and shorten the time of locating lesions, and it is beneficial to improve the efficiency of clinical examination.
