BackgroundPersistent air leak can complicate pulmonary resection, and one management option is dismissal with a chest tube in place. This study evaluated the rate of empyema and readmission after dismissal with a chest tube.MethodsA retrospective review of our prospective database from January 2004 to December 2013 identified 236 patients who were discharged from our institution with an indwelling chest tube and attached one-way valve for air leak. Empyema was defined by leukocytosis or fever and undrained effusion on chest roentgenogram or computed tomography. Readmission was defined as readmission for any reason. Logistic regression analyses were performed to identify risk factors for empyema or readmission.ResultsMedian age was 67 years (range, 18 to 91 years). Median chest tube duration was 18 days (range, 6 to 90 days). Empyema occurred in 40 patients (16.9%), and 62 patients (26.3%) were readmitted. Treatment required included antibiotics alone in 45% (18 of 40), further drainage in 30% (12 of 40), fibrinolytic therapy in 12.5% (5 of 40), and operative decortication in 12.5% (5 of 40). Predictors of empyema included male sex, coronary artery disease, and peripheral vascular disease. A secondary analysis grouping patients into an earlier era (2004 to 2008) vs a later era (2009 to 2013) revealed that the use of thoracoscopy increased from 34% to 48% of lung resections and dismissal with a chest tube increased from 3.4% to 4.5% (p = 0.03).ConclusionsDismissal with an indwelling chest tube is not without consequence, having significant risk for further complications and potential need for additional interventions.Copyright © 2018 The Society of Thoracic Surgeons.
