电子支气管镜不同取材在肺癌诊断中的临床意义

Diagnostic Value of Lung Cancer by E-bronchoscope of Different Sampling

目的研究电子支气管镜的不同取材方式在肺癌诊断中的临床应用价值。方法回顾性分析300例肺癌经电子支气管镜检查后,采用钳检、刷检、X线透视下经支气管肺活检(TBLB)等方法获取标本,比较不同取材及联合取材方法检测肺癌的阳性率。结果三种方法联合取材后总阳性检出率为100%。电子支气管镜下肺癌的形态特征共分4型:腔内增生型、管壁浸润型、管外压迫型、未见异常型[3]。在管壁浸润型和管外压迫型的检出率上,TBLB明显优于刷检与钳检(P<0.05)。钳检在4型的检出率上,均明显优于刷检方法(P<0.01)。结论电子支气管镜检查是肺癌诊断的重要方法之一,采用多种取材方法联合应用可提高肺癌的阳性检出率。

Objective To investigate the clinical significance of e-bronchoscope of different sampling and uniting sampling in lung cancer diagnosis.Methods Retrospect 300 cases lung cancer diagnosed in the department of respiratory.And those cases were retrospectively analyzed with e-bronchoscope and different diagnostic positive rate were compared among clamp biopsy,brush biopsy, and TBLB.Results The total positive rate of three kinds of methods united drawn is I00%. The classification of lung cancer cells under the examination with c-morphological were divided into 4 types, characteristic as proliferative cavity type, the wall infiltrating typc, tube compressed type, normal type. And the test results with three methods arc significantly different in detecting the 4 types of cancer cells（P〈0.05）.Conclusion E-bronchoscopc is the most important methods in diagnosing lung cancer.Uniting sampling by c-bronchoscopc can increase the diagnostic positivc rate of lung cancer.
