ABSTRACT We reviewed the results of the use of the Dumon silicone stents in patients experiencing tuberculous tracheobronchial stenosis since 1994, using a retrospective case review in a university teaching hospital with 1,450 beds serving a population of > 1.8 million. Between February 1994 and September 2001, seven patients with tuberculous tracheobronchial stenosis (mean age, 43 years) underwent a total of 11 dilatations with placement of 10 straight stents and 1 Y stent. Under general anesthesia, all patients underwent rigid bronchoscopy and dilatation of the stenosis with placement of a Dumon stent. There were no deaths. One patient developed a pneumothorax. Two patients experienced migration of the stent, which required reintervention for adjustment of position of the stent. The stents were left in situ for a mean period of 32 months. There was marked improvement in dyspnea in all patients after the procedure, as determined by visual analog scale. Endoscopic dilatation with placement of a silicone stent is an effective treatment for patients with tuberculous tracheobronchial stenosis.

    ABSTRACT: To evaluate whether air pockets (tracheobronchial air columns in the space between the outer surface of the stent and the adjacent airway wall) discernible at computed tomography (CT) can help optimize the time of stent removal in patients with posttuberculosis tracheobronchial stenosis (PTTS). The study was approved by the institutional review board, and informed consent was obtained from all patients. Data from 41 patients (five men, 36 women) with a median age of 39 years (range, 21-64 years) who underwent silicone stent placement owing to PTTS, followed by CT and stent removal 6-12 months after clinical stabilization, were investigated retrospectively. Two radiologists determined whether the extent of air pockets on CT scans was associated with clinical success, which was defined as maintenance of a prosthesis-free airway for more than 2 years after stent removal. Radiologic features were compared for outcome by using a Wilcoxon two-sample test or Fisher exact test. Stents were removed successfully in 31 patients (76%). Air pockets longer than 1 cm or longer than 2 cm were associated with successful stent removal (P = .04 and P = .006, respectively). The sensitivity and specificity of air pocket length in the prediction of successful stent removal were 84% and 50%, respectively, for air pockets longer than 1 cm and 68% and 70% for air pockets longer than 2 cm. The extent of air pockets at chest CT shows correlation with the success of stent removal, indicates regression of stenosis, and may help guide the optimal time for stent removal.

    ABSTRACT: Purpose: Tracheal restenosis due to excessive granulation tissue around a silicone stent requires repeated bronchoscopic interventions in patients with post-tuberculosis tracheal stenosis (PTTS). The current study was conducted to identify the risk factors for granulation tissue formation after silicone stenting in PTTS patients. Materials and Methods: A retrospective study was conducted between January 1998 and December 2010. Forty-two PTTS patients with silicone stenting were selected. Clinical and radiological variables were retrospectively collected and analyzed. Results: Tracheal restenosis due to granulation tissue formation were found in 20 patients (47.6%), and repeated bronchoscopic interventions were conducted. In multivariate analysis, tracheal wall thickness, measured on axial computed tomography scan, was independently associated with granulation tissue formation after silicone stenting. Furthermore, the degree of tracheal wall thickness was well correlated with the degree of granulation tissue formation. Conclusion: Tracheal wall thickening was associated with granulation tissue formation around silicone stents in patients with post-tuberculosis tracheal stenosis.

    ABSTRACT: Endobronchial tuberculosis (EBTB) is defined as tuberculosis infection of the tracheobronchial tree. EBTB may require aggressive treatment, including lung resection, because of severe bronchostenosis and its complications, despite formal anti-TB chemotherapy. We present our experience of treating 25 patients with EBTB. We reviewed retrospectively the medical records of 25 patients with EBTB treated between 2002 and 2012 at the Department of Thoracic Surgery in Beijing Chest Hospital. All 25 patients (5 male, 20 female) underwent surgery for fibrostenotic type EBTB. Bronchoscopy showed fibrostenotic change in all patients and a cough was the most common symptom. Postoperatively, all patients were given anti-TB therapy to take for 6-9 months. EBTB tends to occur at a higher incidence in young women. Surgery may be required for severe bronchostenosis and its complications and should be performed for symptomatic fibrostenotic type EBTB. During the operation, attention should be paid to prevent severe complications and postoperative anti-TB therapy is mandatory.
