Lung collapse study: skip the tube?

This study compares two approaches for treating a large collapsed lung (pneumothorax) in stable adults: the standard chest tube drainage versus simply observing the patient in the hospital and at home. The goal is to see if conservative management works just as well at re-expanding the lung by 8 weeks, while causing fewer complications and shorter hospital stays. About 436 participants aged 18-60 will be randomly assigned to one of the two groups and followed for up to 2 years.
