Abstract

BACKGROUND: Bronchoscopy is an essential procedure for identifying the bleeding site and evaluating cause of hemoptysis. However, it is controversial regarding to the timing of bronchoscopy in patients with hemoptysis. Early bronchoscopy, which was performed during hemoptysis or with 48hour after cessation of bleeding, was better for identifying the site of bleeding compared with delayed bronchoscopy, which was performed 48 hours after cessation of bleeding. The diagnostic yield of identifying the bleeding site by bronchoscopy was variable in reported literature and the safety of early bronchoscopy was not mentioned in previous literature. Therefore, we evaluated the efficacy and safety of early bronchoscopy in patients with hemoptysis. METHOD: From October 1994 to August 1996 in Samsung Medical Center, bronchoscopy was performed in patients with hemoptysis. Early bronchoscopy was performed prospectively during hemoptysis or within 48 hours after cessation of bleeding from May 1995 to August 1996. Delayed bronchoscopy group included patients who did not recieved early bronchoscopy at the same period or in whom bronchoscopy was performed 48 hour after cessation of bleeding from October 1994 to May 1995.
RESULTS
Early bronchoscopy group was performed 73 times in 71 patients. Delayed bronchoscopy was performed in 57 times in 55 patients. There was no difference as to amount and underlying cause of hemoptysis between both groups. Indentification of bleeding site by visualizing active bleeding was significantly higher in early bronchoscopy(38.3%) than delayed bronchoscopy group (8.7%) (p<0.05). Indentification of bleeding site by bleeding after clot removal was 8 in early and 10 in delayed bronchoscopy. Indentification of bleeding site by visualizing active bleeding and bleeding after clot removal was 36 in early and 15 patients in delayed bronchoscopy(p>0.05). Causes of hemoptysis was found in 18 patients in early and 16 patients in delayed bronchoscopy group. patients who had early bronchoscopy underwent surgery. We diagnosed the site of bleeding in 4 patients preoperatively. In 3 patients we made a treatment plan promptly right after bronchoscopy. Among early bronchoscopy group, bleeding over 100cc during bronchoscopy occurred in 2 patients. In early bronchoscopy group there was no other major complication during bronchoscopy.
CONCLUSION
In patients with hemoptysis, early bronchoscopy which performed within 48 hours after cessation of bleeding was more effective procedure for indentifying the bleeding site than delayed bronchoscopy which was performed after 48 hour cessation of bleeding.
