[A case of subglottic stenosis with bridging granuloma after intubation with double-lumen endotracheal tube].

We present a case of subglottic stenosis with rare bridging granuloma after intubation with double-lumen endotracheal tube. An 81-year-old woman was diagnosed with the lung tumor and scheduled for the thoracoscopic surgery. We induced anesthesia with propofol, remifentanil and rocuronium. A 35 Fr double-lumen intratracheal tube was inserted to the trachea with some resistance, when the tube passed through the glottis. A few days later, she suffered from respiratory discomfort. An otolaryngologist examined her larynx and subglottis. Laryngoscopic examination revealed bridging granuloma leading to tracheal stenosis. Tracheostomy and resection of granuloma were performed, and her symptom improved. If we feel resistance in intubating a double-lumen endotracheal tube in a patient with a history of intubation with a tracheal tube, we should operate gently adjusting the size of the tracheal tube.
