Lung biopsy without a breathing tube? small study tests a gentler approach

This pilot study compares two ways to perform a lung biopsy for people with undetermined interstitial lung disease. One method uses a breathing tube and deep anesthesia (standard), while the other uses only mild sedation and numbing medicine. The goal is to see if the gentler method gives biopsy samples that are just as good for making a clear diagnosis. Only 24 adults will take part, and the study focuses on how confident pathologists are in their diagnosis from the tissue samples.
