Effectiveness of thoracoscopic talc pleurodesis in the management of complicated spontaneous pneumothorax.

Background: Complicated (recurring or persistent) spontaneous pneumothorax requires intervention either by surgical or nonsurgical pleurodesis or other interventions. As for high-risk patients, aggressive interventions may be associated with morbidity, the safety and effectiveness of less aggressive alternative interventions like thoracoscopic talc pleurodesis (TTP) should be evaluated. Methods: Data were extracted on patients who had undergone TTP for complicated spontaneous pneumothorax at Interventional Clinic, University Hospital, Brussels, Belgium. The complications, length of hospital stay, and success rate over a 24-month period were studied. Results: A total of 41 TTP procedures were performed for 25 961%) cases of primary spontaneous pneumothorax and for 16 939%) cases of secondary spontaneous pneumothorax. Twenty-four cases were first episodes, whereas it was a recurrence in 17. Of 4 patients with blebs/bullae, 2 had recurrence after TTP. No patient had acute respiratory distress syndrome or any other serious complication after TTP. Recurrence rates after TTP in primary and secondary spontaneous pneumothorax were 9.5% and 25% at 24 months, respectively. The mean length of hospital stay after TTP was 3 +/- 3.2 days. Conclusions: TTP is a safe and effective intervention in complicated spontaneous pneumothorax.
