Postoperative Air Leaks After Lung Surgery: Predictors, Intraoperative Techniques, and Postoperative Management.

Postoperative air leak is one of the most common complications after pulmonary resection and contributes to postoperative pain, complications, and increased hospital length of stay. Several risk factors, including both patient and surgical characteristics, increase the frequency of air leaks. Appropriate intraoperative tissue handling is the most important surgical technique to reduce air leaks. Digital drainage systems have improved the management of postoperative air leak via objective data, portability, and ease of use in the outpatient setting. Several treatment strategies have been used to address prolonged air leak, including pleurodesis, blood patch, placement of endobronchial valves, and reoperative surgery.
