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.

We report a rare case of granular cell tumor arising in the left lower lobe (LLL) bronchus with secondary obstructive change in a 60-year-old male. The patient was found to have a nodule in the LLL on a computed tomography scan, three months prior to his presentation to the Asan Medical Center. Bronchoscopic biopsies revealed a granular cell tumor. After undergoing LLL lobectomy with bronchoplasty, the patient has not experienced any tumor recurrence.

The mucoepidermoid carcinoma of the bronchus is very rare neoplasm. The histological appearance is an intimate mixture of mucous-producing cell and epidermoid cell. The malignant potency of the tumor was determined by histologic pattern. Bronchoplasty techniques represent the ideal form of excisional therapy for benign endobronchial tumor as well as tumors of low-grade malignant potential, such as bronchial adenoma, and for repair of traumatic airway injuries and benign stricture and selected group of patients with carcinoma of the lung. We experienced a case of-low-grade mucoepidermoid carcinoma in a patient of 21-year old male who has been suffered from hemoptysis episodes for several years. The sleeve resection of left main bronchus and left lower lobectomy due to bronchiectatic change were carried out. The patient are being followed up without specific problem.

Pulmonary hamartoma is one of the most common benign lung tumors. Well-known conventional methods of treatment for lung hamartomas include VATS enucleation or wedge resection, bronchoplasty, and others. Here we present a case of endobronchial hamartoma that was successfully treated with cryosurgery by flexible bronchoscopy.

Rupture of the main bronchus due to blunt chest trauma is very rare, especially In childhood although the incidence is increasing. Early diagnosis and primary repair not. only restore normal lung function but also avoid the difficulties and complications associated with delayed diagnosis and repair. We experienced 2 cases of right main bronchial rupture caused by traffic accidents. Patients suffered from progressively developing dyspnea and subcutaneous emphysema on the neck, anteriorchest,andanteriorabdominalwall. Emergency operations were performed through right posterolateral thoracotomy incision at the 4th intercostal space. Intraoperatively, the right main bronchus completely transsected and separated. Corrective bronchoplasty was performed with end-to-end anastomosis using interrupted suture with 3-0 Vicryle and the suture line was reinforced with azygos vein and parietal pleural flap. Postoperative courses were uneventful and patients discharged without any specific pro lems.

Thirteen patients with lung cancer have undergone bronchoplastic procedures from January 1991 to July 1994 in Kyung Hee univ. Hospital.Among them,twelve patients were male and one patient was female from 33 to 76 years of age.[ mean 56.6 11.5 years of age The pathologic diagnoses were squamous cell carcinoma in twelve patients and adenoid cystic carcinoma in one patient.The bronchoplastic procedures consisted of seven right upper sleeve lobectomies, one right middle sleeve lobectomy, one left lower sleeve lobectomy and four sleeve pneumonectomies. In these sleeve pneumonectomies, right sleeve pneumonectomy was done in three patients and the other was left sleeve pneumonectomy. Including the four sleeve pneumonectomies, carinoplasty was performed in seven patients. Postoperatively, we carried out bronchoscopic suction of intrabronchial secretions in necessary for the prevention of postoperative complication. All except one were discharged without any complication and have been in good condition. Postoperative mortality was in one patient who expired 25days after right middle sleeve lobectomy with respiratory failure.

Endobronchial inflammatory myofibroblastic tumor is a rare primary lung disease. A 39-year-old woman with dyspnea and a productive cough underwent complete surgical resection of a small-sized inflammatory myofibroblastic tumor that invaded the left main bronchus and the carina with lung-saving modified left one-stoma-type carinoplasty. We report this case with a review of literature.

Carinal resection is technically demanding and the surgical risk is relatively high. When tumor is confined around the carina, then lung parenchymal sparing surgery is technically feasible in selected cases. We performed carinal resection and reconstruction without pulmonary resection for a patient suffering with squamous cell carcinoma that involved the carina and this patient had undergone right upper lobectomy 19 months previously due to lung cancer.

Bronchoplastic techniques represent the ideal surgical therapy for benign endobronchial tumors as well as tumors of low-grade malignant potential, such as bronchial adenomas, and for repair of traumatic airway injuries and benign strictures. This approach is also applicable to a select group of patients with carcinoma of the lung, with long-term survival being comparable to that achieved by standard pneumonectomy. Five bronchoplastic procedures were performed at Department of Thoracic and Cardiovascular Surgery, Seoul National University Hospital during 7 months periods from Dec. 1984 to Jun. 1985. Of the 5 patients, 3 patients were male and 2 patients were female and ages ranged from 8 years to 55 years old. The final diagnoses of 5 patients were as followed; traumatic bronchostenosis, endobronchial tuberculoma, carcinoid tumor, tuberculous bronchostenosis and traumatic bronchial fracture. Operative procedures of 5 patients were as followed; resection and end-to-end anastomosis of right main bronchus, left lower lobectomy and wedge resection of bronchus, left upper sleeve lobectomy, right middle and lower sleeve lobectomy and resection and end-to-end anastomosis of left main bronchus. And 2 lungs and 3 lobes could be preserved by these bronchoplastic procedures. There was no post-operative complication or mortality and all patients are being followed up without specific problem.

A 41-year-old female was admitted to our hospital for self-audible wheezing sound and dyspnea. On past history, she has been suffered from chest discomfort, and treated recurrently by other hospitals. But, there was no symptomatic improvement. A stridor and mixed wheezing sound was auscultated on whole lung field. PFT revealed fixed type or variable intra- & extra-thoracic air way obstructive pattern. By bronchoscopy & bronchogram, we found web-like structure on the distal trachea. A bronchoplasty was performed and the post-operative PFT showed slight improvement & she had no more complaints.
