Radiotherapy: a novel treatment for pneumothorax

Treatment of a prolonged air leak with radiotherapy: a case report

Pneumothorax is defined as air in the pleural space. Depending on the severity of the pneumothorax, treatment consists of oxygen therapy, simple aspiration, tube thoracostomy, and pleurodesis. Prolonged air leakage is observed in 25% of the patients who have undergone surgical procedures, such as thoracotomy, pleurectomy, and video-assisted thoracoscopy. The patient presented here is the third reported case successfully treated with radiotherapy. Ventilation scintigraphy was used to localise the air leak, and localised radiotherapy was performed at the targeted location. After radiotherapy, the air leak ceased and at the 3-month followup, the pneumothorax had not recurred. Radiotherapy can be a treatment modality for patients with prolonged air leak, who are not candidates for surgery.

Evidence-based suggestions for management of air leaks

The management of postoperative alveolar air leaks (AALs) continues to challenge thoracic surgeons. AALs increase length of stay and health care costs, and likely lead to other postoperative complications. Staple line buttresses, topical sealants, pleural tents, pneumoperitoneum, and modifications of traditional chest tube management (ie, reduced suction) have all been proposed to help reduce AAL. However, the cost of some of the commercial products being marketed may outweigh their relative effectiveness, and some of these techniques and products have not been adequately studied to date. This article provides a review of the available evidence-based literature that addresses the efficacy of the options currently available to prevent and manage AALs. Management suggestions based on this literature are presented.

Management of alveolar air leaks after pulmonary resection

Air leaks are a common problem after pulmonary resection and can be a source of significant morbidity and mortality. Air leaks are associated with prolonged hospital stays, and infectious and cardiopulmonary complications, and they occasionally require reoperation. Despite reasonably robust literature on the topic, the optimal approaches to manage postoperative air leaks remain controversial. We used available literature and expert consensus to formulate suggestions regarding the preferred approaches to both routine and prolonged alveolar air leaks. This review summarizes our findings.
