Aspirin does not increase bleeding complications after transbronchial biopsy

Herth 2002 trial design and results
Design Prospective comparative study
Treatment Transbronchial lung biopsy while taking aspirin
Control Transbronchial lung biopsy not taking aspirin
Population 1217 patients undergoing transbronchial lung biopsy, 285 taking aspirin
Follow-up Procedure and immediate recovery
Primary endpoint Procedure-related bleeding
Result Procedure-related bleeding occurred in 57 patients overall (4.7%). Minor bleeding affected 5 of 285 (1.8%) taking aspirin and 27 of 932 (2.9%) controls, not significantly different. Severe bleeding occurred in under 1%.
Secondary endpoints Severe bleeding, need for intervention

We conclude that the risk of severe bleeding after transbronchial lung biopsy is small (ie, < 1%) and that the use of aspirin is not associated with any increased risk of bleeding.

How it has aged

Removed a routine and often unnecessary interruption of antiplatelet therapy before bronchoscopy. Observational rather than randomised, but the sample is large and the effect direction has never been challenged.
