目的 :对原发性气管恶性肿瘤的误诊情况进行总结 ,探讨提高诊断率的方法。方法 :对 70例气管恶性肿瘤的临床资料及误诊原因进行分析 ,并介绍一例典型病例。结果 :原发性气管恶性肿瘤发病率低 ,误诊率高 ,分别为 0 .0 75%、81.4 % (57/70 ) ,多误诊为慢支、支气管哮喘及喉、食管疾病 ,常规胸片对诊断意义不大 ,大多数通过 CT、纤支镜检查确诊。结果 :1临床医生提高对本病的警惕性 ,详问病史、全面体检 ,CT及纤支镜配合检查可提高诊断率 ;2指出对初诊为“哮喘”的病人应警惕除外气管肿瘤。
Objective: To summarize the misdiagnosis of primary tracheal malignancies and to explore ways to improve the diagnostic rate. Methods: The clinical data of 70 cases of tracheal malignancies and the causes of misdiagnosis were analyzed, and a typical case was introduced. Results: The incidence of primary tracheal malignancy was low, with a high misdiagnosis rate of 0. 75% and 81. 4% (57/70), respectively, which were mostly misdiagnosed as chronic bronchial asthma and larynx and esophageal diseases. Diagnosis is of little significance, most confirmed by CT, bronchoscopy. Results: 1 Clinicians to improve the vigilance of the disease, detailed medical history, a comprehensive physical examination, CT and bronchoscopy with the examination can improve the diagnostic rate; 2 pointed out that the newly diagnosed as “asthma” patients should be wary of tracheal tumor.
