Patient: Description of condition (time of onset, main symptoms, hospital visited, etc.): The patient is male, 26 years old, previously in good health. After a car accident on September 26, 2009, he suffered a tracheal rupture and left pulmonary pneumothorax, and was then treated at the First Hospital of Shanxi University and Shanxi Provincial People’s Hospital, and was discharged after more than a month. 1.He had trachea formation surgery in Shanxi Provincial People’s Hospital, and has been coughing after treatment, but it is not serious, other physical conditions are basically normal. 2. In the last month, I had a strong cough and spit yellow sputum, and was diagnosed with pneumonia on the left side by Lvliang People’s Hospital. I appreciate your help and look forward to your help. Thank you! Department of Respiratory Medicine, Central and Western Medicine Hospital: The left main bronchus is stenosed with sarcoid tissue and obstructive pneumonia, which can be removed by bronchoscopy with subglottis, radiofrequency ablation or freezing, and biopsy. 2. How much will this surgery cost and how long will the hospital stay be? The key depends on whether the flesh and teeth tissue is caused by tissue repair after trauma, or by a foreign body such as sutures, or by bronchial tuberculosis, and also on the degree and length of stenosis. If the obstruction is not too heavy, it can be done under local anesthesia without hospitalization, and if you don’t need to put a stent, it doesn’t cost much, but it is expensive to put a stent, which is about 10,000.
