摘要
目的探讨无引导鞘管径向超声联合测量技术引导下经支气管冷冻肺活检在肺外周病变诊断中的临床价值。方法选取2019年1月至2020年6月佛山市南海区人民医院呼吸内科门诊及住院部胸部CT平扫证实肺部存在外周病灶、但电子支气管镜检查未发现支气管内存在病变的180例患者为研究对象,按照随机数字表法分为观察组1、观察组2和试验组,各60例,观察组1采用带引导鞘管(GS)支气管内径向超声引导下经支气管钳夹活检术(R-EBUS-GS-TBFB);观察组2采用无GS支气管内径向超声联合测量技术引导下经支气管钳夹活检术(R-EBUS-测量技术-TBFB);试验组用无引导鞘管径向超声联合测量技术引导下经支气管冷冻肺活检(R-EBUS-测量技术-TBCB)。比较各组肺活检术并发症、肺活检术平均操作时间和肺活检术确诊率。结果试验组患者肺活检并发症的发生率低于观察组1和观察组2;试验组患者肺活检术平均操作时间少于观察组1和观察组2;试验组的肺活检准确率(85.00%)高于观察组1(65.00%)和观察组2(70.00%)(P<0.05)。结论R-EBUS-测量技术-TBCB在诊断肺外周病变的准确性和安全性高于R-EBUS-GS-TBFB、R-EBUS-测量技术-TBFB。
Objective To evaluate the diagnostic value of non-guided sheath radial ultrasound combined with measurement technique guided transbronchial frozen lung biopsy(R-EBUS-MT-TBCB)in patients with peripheral pulmonary lesions(PPLs).Methods A total of 180 patients with peripheral pulmonary lesions confirmed by chest CT scan in outpatient department and inpatient department of respiratory medicine of The People's Hospital of Nanhai District from January 2019 to June 2020 were selected as the research objects,and they were randomly divided into observation group 1,observation group 2,and experimental group,60 cases in each group:Observation group 1 was performed via bronchial forceps biopsy guided by intrabronchial radial ultrasound with guided sheath tube(GS);Observation group 2 underwent bronchial forceps biopsy guided by GS combined intrabronchial radial ultrasound.The test group used R-EBUS-measurement technology-TBCB.The complications of lung biopsy were observed in each group.Average operation time of lung biopsy in each group;Diagnosis rate of lung biopsy in each group.Results The incidence of lung biopsy complications in experimental group was lower than that in observation group 1 and observation group 2.The mean operation time of lung biopsy in experimental group was less than that in observation group 1 and observation group 2.The accuracy of lung biopsy in experimental group(85.00%)was higher than that in observation group 1(65.00%)and observation group 2(70.00%)(P<0.05).Conclusion As a potentially better method to diagnose PPLs,R-EBUS-MT-TBCB significantly improves both the safety and the diagnosis rates.
