Endobronchial drainage of lung abscess: The use of laser

The management of lung abscess is usually conservative. However, in some cases drainage is necessary, commonly performed transcutaneously. Endobronchial catheter drainage is a potential alternative, though reported only sporadically. Transbronchial pigtail catheter drainage was used in 3 patients with refractory lung abscesses at our centre. The catheter was introduced endobronchially under bronchoscopic procedure. Laser was used to perforate the abscess wall through the airway into the abscess in order to provide a pathway for catheter insertion. An improvement in clinical and radiological parameters was noted immediately after catheter placement. The catheters were extracted after 4-6 days. All patients had a complete clinical recovery. Endobronchial catheters with the use of laser appear to be relatively safe and effective for the treatment of pulmonary abscess in selected patients in whom the abscess is adjacent to the central airway. When necessary, a bulge in an adjacent airway can be perforated with laser. To the best of our knowledge, there have been no previous reports of endobronchial drainage with the use of laser.
