She was diagnosed with asthma at the local hospital and has been applying asthma medication, but the symptoms of respiratory distress were not significantly relieved. 2 months ago, the patient’s respiratory distress worsened again and became more serious with a little activity. The patient had to undergo open-heart surgery in the past, and the risk of anesthesia for tracheal tumor was particularly high. After the preoperative preparation, rigid tracheoscopy was performed for Wan’s tracheal tumor, and on the first day after the operation, the patient’s breathing difficulty completely disappeared and she was able to walk like flying. She is now waiting for the pathology result before the next treatment. Tracheal tumors are often misdiagnosed as bronchitis or asthma because of their similar symptoms. For patients with chronic cough and wheezing, bronchoscopy should be performed to clarify the tracheal condition. Benign and malignant tracheal stenosis is an indication for rigid bronchoscopy technique, which establishes a lifeline for patients with tracheal stenosis and brings a boon to this group of patients, greatly improving the quality of life and survival of patients with tracheal stenosis.
