In a series of 226 patients with spontaneous pneumothorax, 167 (74%) were managed successfully on an outpatient basis by observation (20%) or by intercostal tube drainage and a flutter valve (54%). Only 59 patients (26%) were hospitalized, and 42 of these were treated surgically (18.6%). Outpatient management with a flutter valve has proved to be safe, efficient, and economical.
