Spontaneous primary and secondary pneumothorax: a 10-year study of management alternatives.
OBJECTIVE
To study the outcome of conservative and surgical management of spontaneous pneumothorax.


METHODS
Retrospective study between January 1980 and December 1990, with a mean follow-up of 6.5 years.


METHODS
A tertiary-care university hospital with a referral thoracic surgical unit.


METHODS
All patients seen in the study period with spontaneous pneumothorax. Those with traumatic, iatrogenic or ventilator-associated pneumothoraces were excluded. There were 366 consecutive patients who had 508 episodes of spontaneous pneumothorax. Two hundred and thirty-nine patients had primary spontaneous pneumothorax (group 1); 127 had secondary spontaneous pneumothorax (group 2).


METHODS
Tube thoracostomy, apical resection with either pleurectomy or pleural abrasion.


METHODS
Recurrence and outcome after surgical management relative to recurrence, complications, operative technique and mean hospital stay were evaluated by clinical review and questionnaire by an independent observer.


RESULTS
No significant differences were noted between the two groups with respect to the incidence of recurrent spontaneous pneumothorax after the first or second episode, and no significant differences were noted between the two operative techniques with respect to recurrence, complications, operative technique or death rate. However the mean hospital stay was doubled for group 2 patients (9.9 versus 4.3 days).


CONCLUSIONS
Conservative treatment, including tube thoracostomy, was effective for primary and secondary spontaneous pneumothorax. Open surgery was effective in preventing recurrence in 95% of cases in both groups.
