This small study from South Africa shows stab wounds to the chest with a pneumothorax less than 0.5 cm that were managed conservatively had completely resolved on 12 hour repeat chest X-ray. This could facilitate earlier discharge of these patients. It also supports conservative (non-tube placement) approach to asymptomatic small pneumothoraces from stab wounds.
