Suction or Nonsuction: How to Manage a Chest Tube After Pulmonary Resection

Despite several randomized trials and meta-analyses, the dilemma as to whether to apply suction after subtotal pulmonary resection has not been solved. The combination of a poorly understood pathophysiology of the air leak phenomenon and the inadequate quality of the published randomized trials is actually preventing thoracic surgeons from abandoning an empirical management of chest drains. Even digital systems do not seem to have made the difference so far. Based on the evidence of the literature, the authors propose a new air leak predictor score (ALPS) as a contributing step toward appropriateness in using intraoperative sealants, opting for an external suction and managing and chest tubes.
