Abstract
GUERRA, Miguel; MIRANDA, José António; LEAL, Francisco and VOUGA, Luís. Interstitial lung disease: Diagnostic accuracy and safety of surgical lung biopsy. Rev Port Pneumol [online]. 2009, vol.15, n.3, pp.433-442. ISSN 0873-2159.
This study reports our experience, diagnostic accuracy and safety of surgical lung biopsy in patients with interstitial lung diseases. From January 1998 December 2007 surgical lung biopsy was performed in 53 patients (22 female [41.5%]; age 47.2±13 years). A total of 37 patients (69.8%) underwent videothoracoscopic lung biopsy and minithoracotomy was performed in 16 patients (30.2%). Right lung was the choice in 47 patients (88.7%). Postoperative complications were rare (9.4%) and included three prolonged air leaks (5.7%), one pneumothorax requiring a chest drain (1.9%), and one haemothorax requiring reoperation (1.9%). One patient died of cardiac arrest of unknown cause. Average chest tube duration was 4.4±3 days and average hospital stay 5.4±4 days. Lung biopsy contributed to the diagnosis in 50 patients (94.3%). In conclusion, the potential benefits of diagnostic surgical lung biopsy must be considered against the risks of the procedure especially in patients with severe cardiopulmonary dysfunction.
