Introduction: Secondary spontaneous pneumothorax (SSP) commonly afflicts patients with chronic obstructive pulmonary disease (COPD). Indications for surgery remain unclear as these patients often have other co-morbidities which increase risk of surgery as well as concerns of prolonged air-leak. The use of reinforced surgical stapler reloads (RSSR) is one of the methods proposed to decrease incidence of air-leak. We report outcomes following the use of RSSR in SSP patients with COPD. Methods: All COPD patients with SSP who underwent surgical management with the use of RSSR in a single-institution from May 2015 to May 2017 were included. Demographic and clinical data were collected retrospectively. Results: 28 patients with a mean age of 69 (51-93) years were included. All patients were male and smokers with an average smoking pack-years of 45.6 (20-100). One patient had co-existing interstitial lung disease and six had previous or current lung tuberculosis. All patients had intra-operative pleurodesis, either talc (50%), abrasion (7%) or both (43%). Median immediate air-leak measured by a digital-drainage-system post-operatively was 300ml/ min (0-3300). Median duration chest tube in-situ was 7 (2-36) days, with 10 (35.7%) patients discharged home with chest tube in-situ. Fifteen (53.6%) patients had prolonged air-leak (more than five-days). Post-operative complications include 6 (21.4%) patients with pneumonia, 2 (7.1%) requiring ventilator support for more than 48-hours and 2 (7.1%) requiring reintubation. There were four 30-day mortalities; in all the cause-of-death was pneumonia. There was an additional mortality at 90-days due to pneumonia. Conclusion: In our study, the use of RSSR does not decrease the incidence of prolonged air leak in COPD patients with SSP.
