Surgical repair for post-tuberculosis tracheobronchial stenosis

Abstract

Aim Post-tuberculosis tracheobronchial stenosis is rare but one of the most dangerous complications of tracheobronchial tuberculosis. Balloon dilatation, stent insertion, laser photoresection, argon plasma coagulation, and cryotherapy are some of the initial treatments recommended for mild to moderate cases. Here, we report a case series of patients who underwent segmental resection and end-to-end anastomosis for bronchial stenosis and a sliding technique for severe and long-segment tracheal stenosis. Methods We retrospectively reviewed the medical records of patients with post-tuberculosis tracheobronchial stenosis operated on in our thoracic surgery department. Of the 7 cases that were treated, two had severe tracheal stenosis stretching over 50% of the tracheal length, one was operated on using resection and end-to-end anastomosis, and the other had sliding tracheoplasty. The other 5 cases of bronchial stem stenosis were treated with segmental resection and end-to-end anastomosis. Results All five patients with bronchial stenosis had a good outcome; the ipsilateral lung was well ventilated and respiratory function was good. One patient with tracheal stenosis, treated with segmental resection and end-to-end anastomosis, died after the surgery, and the other patient, treated with slide tracheoplasty, had a good recovery. Conclusion The treatment plan for patients with post-tuberculosis tracheobronchial stenosis should be on a patient-by-patient basis. Sliding tracheoplasty can be a treatment option in patients with long-segment tracheal stenosis.
