BackgroundBronchoscopy plays a key role to diagnose the etiology, to localize the site, and to identify the sources of the bleeding in patients with hemoptysis, but the ideal timing of an endoscopic examination is still unclear.MethodsWe performed a secondary analysis of an observational and multicenter study, aimed at evaluating the epidemiology of hemoptysis in Italy and the diagnostic yield of the most frequently prescribed examinations. The aim of the study was to evaluate whether an early bronchoscopy (i.e., performed during active bleeding/48h after hemoptysis stopped) helps localize bleeding (i.e., site, lobe, lung) and increase diagnostic yield in comparison with a delayed examination.ResultsFour hundred eighty-six consecutive adult patients (69.2% males; median [IQR] age: 67 [53-76] years) with hemoptysis requiring an etiological diagnosis and undergoing bronchoscopy were recruited.Bleeding focus could be located more frequently in case of moderate-severe bleedings than in cases of mild hemoptysis (site: 70/154, 45.4%, VS. 73/330, 22.1%; p-value <0.0001; lobe: 95/155, 61.3%, VS. 95/331, 28.7%; p-value <0.0001; lung: 101/155, 65.1%, VS. 111/331, 33.5%; p-value <0.0001). Early bronchoscopy showed a higher detection rate of bleeding source in comparison with delayed examination (site: 76/214, 35.5%, VS. 67/272, 24.6%; p-value=0.01; lobe: 98/214, 45.8%, VS. 92/272, 33.8%; p-value=0.007; lung: 110/214, 51.4%, VS. 102/272, 37.5%; p-value=0.002). Early bronchoscopy did not provide any advantages in terms of increased diagnostic yield, in the total cohort (113/214, 52.8%, VS. 123/272, 45.2%; p-value=0.10) and in the severity subtypes (mild: 56/128, 43.8%, VS. 88/203, 43.4%; p-value=0.94; moderate-severe: 57/86, 66.2%, VS. 35/69, 50.7%; p-value=0.051).ConclusionsEarly bronchoscopy helps detect bleeding sources, particularly in cases of moderate-severe hemoptysis, without increasing diagnostic accuracy.Trial registrationClinicalTrials.gov (identifier: NCT02045394).
