Bullae are common accompaniments of chronic obstructive pulmonary disease especially emphysema. They contribute to increased lung volume and worsen the mechanical disadvantage of the inspiratory muscles by increasing the residual volume (RV) and RV/total lung capacity ratio. Thus effective decompression of a large bulla or bullae is thus important to improve the lung function of affected patients and also to provide symptomatic relief. Surgery and thoracoscopy are two commonly performed procedures used to treat bullae. Although bronchoscopic lung volume reduction has been successfully accomplished for emphysema, isolated decompression of bullae bronchoscopically has not been tried to date.

A large emphysematous bulla in the left lower lobe of a surgically unfit patient was bronchoscopically punctured with a transbronchial aspiration needle; the position of the needle inside the bulla was confirmed and the air from the bulla was aspirated slowly to allow collapse. Finally, some autologous blood was instilled into the bulla before the needle was withdrawn.

The patient had immediate and sustained symptomatic relief with significant improvement in lung function.

Bronchoscopic transbronchial decompression of emphysematous bullae can be an effective therapeutic option and warrants further investigation.
