Pleural tenting as an effective adjunct in patients with pneumothorax secondary to emphysema evaluated with computed tomography scan

Surgical treatment for secondary spontaneous pneumothorax: a risk factor analysis

PURPOSE

While surgery is an effective treatment for secondary spontaneous pneumothorax (SSP), it can be difficult, because affected patients are usually in a poor general condition. The present study investigated the risk factors of postoperative complications after surgery for SSP.

METHODS

Eighty-eight patients with SSP who underwent surgery from January 2006 to March 2018 were investigated. Clinical data were reviewed, and a multivariate analysis was performed.

RESULTS

Eighty-four patients (95%) were males, and the median patient age was 72 years. Underlying lung diseases were chronic obstructive pulmonary disease in 58 patients (65.9%), interstitial pneumonia in 26 (29.5%), and others in 4 (4.5%). Postoperative complications developed in 21 patients (24%). Hospital mortality/prolonged length of stay occurred in 6 patients (7%). A multivariate analysis showed that the preoperative performance status (performance status 0-2 vs. 3, hazard ratio: 6.570, 95% confidence interval: 1.980-21.800) was an independent predictor of postoperative complications.

CONCLUSION

Surgery for SSP contributed to early chest tube removal and favorable outcomes. However, rare fatal events occurred, and the patient performance status was a risk factor for postoperative complications. A careful evaluation of each patient's performance status is needed to determine the need for surgical intervention for SSP.
