Surgical treatment of endobronchial tuberculosis

Abstract

The incidence of tuberculosis remains fairly high in some developing countries. Endobronchial tuberculosis may cause bronchostenosis, with potentially severe respiratory symptoms, atelectasis and secondary pneumonitis. Thirty-two surgically treated cases of tuberculous bronchostenosis (33 operations) are presented. In 13 cases segmental resection or lobectomy was performed with bronchoplastic procedures. Anastomotic stenosis necessitated pneumonectomy 5 years later in one of the 13 and one patient had wound infection. Nineteen patients underwent pulmonary resection without bronchoplasty. Apart from the patient with anastomotic stenosis, all 32 were symptom-free in the follow-up period. Forced expiratory volume was significantly improved in the ten tested patients with bronchoplasty. The results suggest that surgical treatment is safe for endobronchial tuberculosis with poor response to specific chemotherapy. In addition to checking progression of the disease, bronchoplasty helps to preserve lung function. Appropriate chemotherapy should be given for 9-12 months perioperatively to prevent recurrence and restenosis.
