电磁导航支气管镜在肺外周结节诊断中的意义

目的探讨电磁导航支气管镜(ENB)对肺外周结节的诊断意义。 方法选择2014年6月至2016年5月于上海市肺科医院住院患者83例，进行ENB检查，术中导航成功后结合外周超声确认位置，并在X线透视下进行标本获取，送病理学检测。根据检查结果来确定ENB对肺外周结节的诊断价值。 结果共有83例患者接受ENB检查，合计87处病灶，阳性诊断率为86.00%。导航时间为(23.06±15.68)min，曝光时间为(1.89±1.53)min，手术时间为(75.27±37.08)min；无并发症发生。较既往文献报道的单纯外周超声系统曝光时间(4.08±3.27)min缩短，差异有统计学意义(t＝7.32，P<0.05)。 结论熟练使用导航联合外用超声技术是避免操作并发症的关键步骤。利用ENB技术诊断肺外周小结节具有较高的阳性率，值得进行临床推广。

The Diagnostic value of electromagnetic navigation bronchoscopy for pulmonary peripheral nodules

ObjectiveTo explore the diagnostic value of electromagnetic navigation bronchoscopy (ENB) for pulmonary peripheral nodules. MethodsEight-three patients from June 2014 to Mar 2016 in Shanghai Pulmonary Hospital were enrolled.The ENB was performed on those patients who were detected peripheral lung nodules by chest CT.After being successfully navigated, the lesion location was confirmed by peripheral ultrasound and specimens were acquired under X-ray assistant.The specimens were finally sent to determine the pathologic classification and the value of ENB was determined according to the pathologic examination results. ResultsA total of 83 patients were enrolled in this study and the lesions were 87, the positive predictive was 86.00%.The mean navigation time was (23.06±15.68)min, exposure time was (1.89±1.53)min, operation time was (75.27±37.08)min, and no procedure-related complications were observed.The exposure time was significantly shorten than that in patients who were confirmed the location of peripheral lung nodules by peripheral ultrasound merely (t=7.32, P<0.05). ConclusionSkilled operation is the successful key to avoid complications.The positive rate of ENB in the diagnosis of pulmonary peripheral nodules is high and ENB is worth promoting.
