Usefulness of endobronchial stenting for nonmalignant right middle lobe syndrome.

We report herein a case of nonmalignant middle lobe atelectasis of the right lung resulting in significant stenosis of the airway. The new short self-expandable metallic stents (SEMS) were used to perform temporary stenting and expansion of the right middle lobe airway. SEMS have been used to treat airway obstructions in the trachea, as well as the right and left carina, but few studies have looked at placing SEMS at the level of the bronchi, especially right middle lobe bronchus.
