对有咯血而胸部 X 线照片正常的病人,常做支气管镜检查以排除支气管癌,然而有人认为胸部 X 线正常者并无明确的支气管镜检指征。Weaver 等建议如病人超过40岁,咯血持续1周,胸片正常者可做支气管镜。Jackson 等则提出40岁以上病人做纤支镜,40岁以下病人因肺癌发生率低可仅进行无创性检查。然而 Peters 等则认为对咯血而胸片正常即使有可能发展为肺癌的病人,支气管镜检查在诊断和治疗上并无任何优越性。为了估计上述观点的正确性,作者复习了58例咯血而胸部 X 线正常并已做过纤支镜检查的病人的资料。
In patients with hemoptysis and normal chest radiographs, bronchoscopy is often performed to rule out bronchial cancer, whereas some people who have normal chest X-rays do not have definite bronchoscopic signs. Weaver and other recommendations such as patients over the age of 40, hemoptysis continued for 1 week, chest X-ray can do bronchoscopy. Jackson et al. Proposed that patients over the age of 40 should be treated for bronchofibroscopy. Patients under the age of 40 due to low incidence of lung cancer can only be noninvasive. However, Peters et al. Concluded that bronchoscopy did not have any diagnostic and therapeutic advantages in patients with hemoptysis who had normal chest radiographs, even with lung cancer. In order to estimate the correctness of the above observations, the authors reviewed the data of 58 patients with hemoptysis who had normal chest radiography and had undergone bronchoscopy.
