Conditions

spontaneous pneumothorax

Interventions

After the bulla causing the pneumotorax is resected by linear stapler, both edge of staple-line are ligated by polydioxanone sutures. Then, the staple-line is covered by &quot
press-sheet type Integran(R)(100x50mm size)&quot
, followed by fixtation of the sheet using the sutures on the staple edge. After the day after surgery, the drainage tube is removed when investigator identify the stop of air leakage and decrease of

Secondary

MeasureTime frame
