Tuberculosis involving the central airway occasionally results in diffuse stenosis in the distal trachea and main bronchus. When the stenosis is more limited to the main bronchus, sleeve resection can be performed with high likelihood of a good result. Bronchial stenosis limited to 2 cm is considered favorable for bronchial sleeve resection. However, a longsegment stenosis may make sleeve resection difficult or impossible, and pneumonectomy or therapeutic bronchoscopy may be performed. An extended sleeve lobectomy is a procedure to remove more than one lobe using a bronchoplasty technique and its applications to the patients with locally advanced lung cancer were reported. We performed an extended sleeve lobectomy in a patient with tuberculous bronchial stenosis involving the right main bronchus, bronchus intermedius, right middle lobar bronchus and right lower lobar bronchus, and report this case with review of literatures.

A 20 year old woman had developed stenosis at the lower part of the trachea, right main bronchus, and right upper lobe bronchus as a complication of endobronchial tuberculosis. The patient had complained of severe dyspnea. Tracheobronchial stenosis was so extensive that we did reconstruction of the trachea and right bronchus with resection of the lower trachea and right main bronchus and right upper lobectomy. She has been doing well without any respiratory symptoms or complications.

For the treatment of bronchial stenosis due to trauma, inflammatory and neoplastic lesion, bronchoplastic procedure in the interest of preservation of lung tissue are relatively new developments in the field of thoracic surgery. We reported on case of bronchoplasty using to pericardial patch for the treatment of bronchial stenosis due to chronic inflammation. The patient was 26 years old female and chief complaint was respiratory difficulty. Bronchogram revealed diffuse stenosis of left main bronchus about 4cm and especially, at just below the carina marked narrowing of lumen and fine serration in the wall. At the time of operation, longitudinal incision was made at left main bronchus about 5cm and reconstructed bronchus using to pericadial patch at membranous compartment of bronchus. The postoperative course was uneventful and post-operative follow up bronchography showed that improvement of bronchoplastic segmented region.

Background Insertion of tracheal stent in the treatment of benign tracheal & bronchial disease has increased since the introduction of expandable metallic stent. Material & Methods : Between Jan, 1995 and Feb. 2004, eight patients who had benign tracheo-bronchial disease underwent insertion of expandable metallic tracheal stent. We retrospectively analyzed stent insertion indications, complications, and following the result. Results : Surgical indications were post-intubation tracheal stenosis (1 case), tracheal stenosis following tracheal surgery (2 cases), tracheo-esophageal fistula (2 cases), broncho-pleural fistula(1 case), left main bronchus stenosis following bronchoplasty (1 case), and left main bronchus stenosis due to mediastinal repositioning (1 case). Expandable metallic tracheal stent was inserted in five patients to resolve dyspnea caused by airway obstruction, and to prevent recurrent pneumonia in three patients. The complication developed in 6 patients $75\%$; 3 cases of distal stenosis due to growth of granulation tissue, and one case each of tearing of posterior membrane, aggravation of tracheo-esophageal fistula, and airway partial obstruction due to stent migration. The stent was removed in 5 patients and tracheal surgery (tracheal resection and end to end anastomosis with primary repair of esophagus, pericardial patch tracheo-bronchoplasty, tracheal repair and omental wrapping) was performed in 3 patients. Conclusion Insertion of self expandable metallic stent in benign tracheo-bronchial disease is an effective means of relieving dyspnea for only a short period, and it did not increase the long term survival. Better means of treatment of benign tracheo-bronchial stenosis in necessary.

Most of the patient with endobronchial tuberculosis have some degree of bronchial stenosis. however, a part of bronchial stenosis need aggressive treatment for the patency because of severe symptoms. The self-expendable metallic stents provide palliative treatment for narrowed airways where surgical resection is inadvisable. We experienced a successful left wedge pneumonectomy on a 29-year-old woman with obstruction of left main bronchus due to complication of the bronchial stent. She had inserted self-expendable metallic stents on left main bronchus of the tuberculous bronchial stenosis two times. There was no specific postoperative complication.

We experienced 5 cases of tracheal stenosis and 7 cases bronchial stenosis treated surgically at the Department of Thoracic and Cardiovascular Surgery, School of Medicine, Hanyang University during 5 years. The causes of tracheal stenosis were prolonged endotracheal intubation 1 case, tracheostomy 1 case, the sequela of endobronchial tuberculosis 2 cases and tracheomalacia 1 case. The causes of bronchial stenosis were all endobronchial tuberculosis. The managements of tracheal stenosis were tracheal resection and end to end anastomosis. The resected lengths of trachea were 1.5cm, 3cm and 7.5cm. One case of suglottic stenosis was underwent the resection of trachea, 8cm in length, and the laryngotracheal anastomosis was done, but the re-stenosis of trachea was developed after 4 weeks post-operatively. One case of tracheomalacia was done permanent tracheostomy only, because the entire trachea was adhered to the surrounding tissue. The managements of bronchial stenosis were resection of involved lobe or one lung, in the 5 case. One case with Lt. main bronchial stenosis and atelectasis of Lt. upper lobe was done the lobectomy of Lt. upper lobe only and then, the Lt. pneumonectomy was done re-operatively because the atelectasis of Lt. lower lobe had continued. The other one case with stenosis of Rt. main bronchus, failed the insertion of metalic stent, was underwent the Rt. upper lobe lobectomy, sleeve resection and side to end anastomosis

We report successful application of dual trachcobronchial stcnt to the diffuse tracheal stenosis. An one-month-old boy was transferred to the emergency room due to tachypnea and respiratory difficulty with COB retention. Preoperative computed tomography revealed pulmonary artery sling with diffuse tracheal stenosis. We found that the diameter of the both main bronchus was less than 3mm and the trachea was a complete ring. We divided the left pulmonary artery and implanted it to the main pulmonary artery under cardiopulmonary bypass. After that, tracheoplasty was performed with autologous pericardium. However, after the initial measures, CO2 retention and respiratory difficulty persisted due to the granulation tissue and dynamic obstruction of the airway ensued by the overlying pericardial flap. Therefore, we decided to apply a single tracheal stunt. After the insertion of tracheal stent, residual stenosis of the both main bronchus opening continued to cause respiratory difficulty Finally we applied dual tracheobronchial stent and resolved the airway obstruction.

Flow-volume loop is known to be useful in the diagnosis of upper airway obstruction. In cases of tracheal obstruction, characteristic features such as fixed or variable upper airway obstruction patterns give clue to the diagnosis. But the flow-volume loop of unilateral mainstem bronchial stenosis is not known well. There is controversy in patterns of flow-volume loop in unilateral mainstem bronchial stenosis (restrictive pattern or biphasic pattern). We report a case of biphasic flow-volume loop in left mainstem bronchial stenosis(4-5 mm in diameter) as a sequela of endobronchial tuberculosis, which recovered normal flow-volume loop after metallic stent insertion and 2 months later showed reappearance of biphasic pattern because of restenosis of left mainstem bronchus due to growth of granulation tissue at the stent site.

Endobronchial tuberculosis is defined as a tuberculous infection of the tracheobronchial tree and has a prevalence of up to 50% in active pulmonary tuberculosis cases. The most common complication of endobronchial tuberculosis is bronchial stenosis; benign fistula formation by endobronchial tuberculosis is rare, especially inter-bronchial fistula formation. We reported a rare case of a 73-year-old woman with a fistula between the right upper bronchus and bronchus intermedius. A diagnosis of inter-bronchial fistula caused by endobronchial tuberculosis was based on the results of chest computed tomography scans, bronchoscopy, and microbiological and pathological tests. The patient was treated with anti-tuberculous medication, and her symptoms gradually improved.

Recently we have experienced one case of long tracheal stenosis which developed after pulmonary tuberculosis. The patient was 32 years old woman, 165cm in height. She complained severe dyspnea and headache. We could hear the inspiratory wheezing sound and stridor without stethoscope. Preoperative tracheogram and chest CT scan showed long tracheal stenosis from the posterior portion of clavicular head to the upper portion of carina and right main bronchus. Under the general anesthesia, the stenotic segment, about 7.5cm, was resected and end to and anastomosis was performed successfully through the right anterolateral thoracotomy and supraclavicular collar incision. Her postoperative course was uneventful and the patient has remained well till now.
