We reviewed the records of 264 patients who underwent fiberoptic bronchoscopy for unexplained hemoptysis to determine the various causes of hemoptysis. Bronchogenic carcinoma (29%), bronchitis (23%), and idiopathic hemoptysis (22%) accounted for the majority of causes of hemoptysis. In contrast to older studies, the incidence of hemoptysis secondary to tuberculosis and bronchiectasis has decreased. Although our patient population is predominantly male and elderly, our data may well be representative of more recent epidemiologic trends in causes of hemoptysis.
我们回顾了264例因不明原因咯血而接受纤维支气管镜检查的患者记录，以确定咯血的各种原因。支气管源性癌（29%）、支气管炎（23%）和特发性咯血（22%）占咯血原因的大部分。与以往的研究相比，继发于肺结核和支气管扩张的咯血发病率有所下降。尽管我们的患者群体以男性和老年人为主，但我们的数据很可能代表了咯血原因的最新流行病学趋势。
