Lee HJ, et al. - This inquiry was set up to determine the predictive factors associated with the development of airway stent complications. Furthermore, researchers intended to elucidate an optimal surveillance period for follow-up bronchoscopy for early detection and possible prevention of stent-associated complications. Irrespective of symptomatic status and indication for stent placement, the possible usefulness of surveillance bronchoscopy was indicated for the early detection of complications and their subsequent management, when performed within 4 to 6 weeks of stent placement.
