Abstract

Introduction: Secondary spontaneous pneumothorax (SSP) occurs as one of the complications associated with interstitial pneumonia (IP). Chest drainage is performed when there is a large volume of air in the pleural space. Notably, SSP with IP (SSP-IP) is frequently not curable by chest drainage only. A digital drainage system (DDS) provides an objective evaluation of air leakage and maintains a pre-determined negative pressure, compared to an analog drainage system (ADS). Few studies have reported the effectiveness of DDS in the treatment of SSP-IP. This study aimed to assess the usefulness of DDS for SSP-IP.

Methods: This retrospective study included patients with SSP-IP who had undergone chest drainage. We reviewed the included patients' medical records, laboratory data, computed tomography findings, and pulmonary function data.

Results: DDS was used in 24 patients and ADS in 49 patients. The mean duration of chest drainage was 11.4 ± 1.9 days in the DDS group and 14.2 ± 1.3 days in the ADS group, which was not significantly different (p = 0.218). Surgery, pleurodesis, and/or factor XIII administration were performed in 40 patients. Additionally, five (20.8%) patients in the DDS group and nine (18.4%) in the ADS group had a recurrence of pneumothorax within 4 weeks (p = 1.000). One patient (14%) in the DDS group and six (12.2%) in the ADS group (p = 0.414) were cured of pneumothorax but later died.

Conclusion: DDS did not demonstrate a significant difference in the shortening of chest drainage duration. Further study is needed to validate the results of this study.
