    • Abstract

    Background:
    Digital drainage system (DDS) has been recently recognized as a useful device in postoperative chest drainage. However, there is no past study predicting the efficacy of pleurodesis using DDS for postoperative air leak. The aim of this study is to identify predictive factors of the efficacy of pleurodesis including the observed data in DDS log.
    
    Method:
    The 857 patients underwent pulmonary resection and were made use of DDS for chest drainage postoperatively from January 2015 to December 2016. We retrospectively reviewed clinical database and log data of DDS, and compared the patient who stopped postoperative air leak by single pleurodesis with the patient who needed two or more pleurodesis. Fisher’s exact test was used to compare categorical values, and Mann-Whitney U test was used to analyze continuous values. The cut-off values were decided by receiver operating characteristic curve.
    
    Result:
    The 40 patients underwent pleurodesis for postoperative air leak. The median age was 70 years (range, 51 to 86), and 83% of patients were men. The most common type of surgery was lobectomy (90%). Postoperative air leaks in the 23 patients (58%) were stopped by single pleurodesis, and those in the 17 patients (42%) needed pleurodesis more than two times to stop air leak. The predictive factors to stop air leak by single pleurodesis were lower air leak flow at the time of pleurodesis (P = 0.02), and lower average of air leak flow for 24 hours before pleurodesis (P = 0.05). The cut-off value of air leak flow was 100 ml/min, and average of air leak flow for 24 hours was 130ml/min.
    
    Conclusion:
    Air leak flow at the time of pleurodesis and the average for 24 hours in DDS log were useful predicters of stopping air leak by single pleurodesis.
