Tracheobronchomegaly or Mounier-Kuhn syndrome a is rare disease characterized by marked dilatation of the trachea and main bronchi. It is thought to be due to a congenital anomaly, but is uncertain. It has variable clinical manifestations from causing chronic respiratory infections and bronchiectasis to being asymptomatic for the lifetime. Recently, we experienced a case of Mounier-Kuhn syndrome patient with tracheal diverticulum, who had lung cancer. Our case is reported with literature reviews.

Background: For the relief of the occlusion of major bronchi, laser therapy, radiation therapy or combined therapy is generally used. But the effect of radiation therapy is very slow and not consistent and laser therapy requires expensive equipments and technical expertise with occasional serious side effects. Direct ethanol injection has been widely used for the control of bleeding in gastrointestinal lesion, esophageal varices or renal cell carcinoma with good results. So we tried direct injection of ethanol into the tumor to relieve the obstruction of major bronchus in 11 patients. Method: All procedures were done under the fiberoptic bronchoscopy with continuous oxygen supplement and aliquoted 0.5-1.0 ml of absolute ethanol directly into the tumor through the endobronchial aspiration needle. The tumor was endoscopically removed with a biopsy forceps immediately after ethanol injection. The whole procedure was repeated 3-4 days interval until the lumen opens. Usually after 2-3 trials of ethanol injection, the lumen opened up. Results: The immediate effect of ethanol injection was whitening of the mucosa and prompt cessation of bleeding. The late effect was necrosis of the tumor. The final results of this procedure were improvement of symptoms and reexpnasion of the lung in all patients. $FEV_{1.0}$ and FVC were improved and $PaO_2$ was increased from $68.1{\pm}9.2$ mmHg to $83.9{\pm}8.1$ mmHg, $SaO_2$: from $94{\pm}8.5%$ to $96.6{\pm}1.1%$, and $AaDO_2$ was reduced from $26.5{\pm}8.5$ mmHg to $10.9{\pm}9.1$ mmHg. Conclusion: Direct ethanol injection into the tumor tissue is a rapid, cheap and relatively safe method of relieving the complete occlusion of major bronchus.

Mucoepidermoid carcinoma of lung are rare carcinoma arising from the submucosal glands tissue of the proximal tracheobronchial tree. The carcinoma can be divided into low grade and high grade varienties. The most important factors in the prognosis include histological grading and the ability to achieve a complete surgical resection. We experienced a case of high grade mucoepidermoid carcinoma in pulmonary tuberculosis patient of 67 years old male who has been suffered from left chest pain for several weeks. He was not treated and died seventeen months later.

Tracheopathia osteoplastica(TO) is a rare, clinical and pathologic benign condition of unknown cause and characterized by submucosal cartilaginous or bony projections into tracheobroncheal lumen, usually not involved posterior membranous portion of tracheobroncheal tree. We report two cases of tracheopathia osteoplastica that involved trachea and both main bronchus, diagnosed by chest CT, fiberoptic bronchoscopic biopsy.

Bridging bronchus (BB) is an extremely rare tracheobronchial anomaly. This anomaly is often associated with a sling left pulmonary artery (SLPA) and is diagnosed in infancy or at autopsy. A 29-year-old female patient with previous history of pulmonary tuberculosis was admitted because of persistent fever, cough and sputum. Fiberoptic bronchoscope and chest computed tomography revealed a bridging bronchus and associated atelectasis. The right middle and lower lobe was supplied by a bronchus which originates from the left main bronchus and bridges the mediastinum. There was no anomaly of a left pulmonary artery. Right middle and lower bilobectomy was performed.

A case of endobronchial tuberculosis with left main bronchial stenosis and atelectasis of left lower lobe in a 26-year-old female is reported. She had taken antituberclous agents for 9 months, but she complained of chest pain and coughing. Bronchoscopy revealed patency of left upper bronchus and bronchiectasis of left lower lobe. She underwent left lower lobectomy with bronchoplasty. After the operation she had significant improvement of pulmonary function. Although surgical treatment of endobronchial tuberculosis is controversial, bronchoplastic surgery can be an effective treatment of tuberculous bronchial stenosis because it relieves patients from symptoms by preserving lung functions.

Bronchogenic cyst is an uncommon congenital lesion which is derived from the primitive foregut. Most bronchogenic cyst may develope at the tracheal bifurcation, both main bronchi, the lung parenchymeand the mediastinum. A 40-year old male was evaluated for dyspnea and chest tightness. Computed tomography revealed a well dermarcated, 7.2 ${\times}$ 7.9 cm sized, homogeneous mass compressing the left atrium. 2D-echo showed grade III mitral regurgitation. We completely removed the cystic mass and then confirmed the bronchogenic cyst in the pathological diagnosis. During the follow up period, the patient progressed well without any symptoms and showed grade I mitral regurgitation on the 2D-Echo. Therefore, we report a case of the bronchogenic cyst causing grade III mitral regurgitation.

Background : Airway obstruction due to blood clot occurs unusually but in a variety of clinical settings. Initial efforts for removal of the endobronchial blood clot involve flexible bronchoscopic evaluation with saline lavage and suctioning and then forceps extraction. If unsuccessful, further options include rigid bronchoscopy, Fogarty catheter dislogement of the clot, and topical thrombolytic agents. The several successful uses of endobronchial streptokinase or urokinase to dissolve an endobronchial blood clot have been previously reported, but not yet in Korea. Herein we describe a 51-year old man with superior vena cava thrombosis secondary to Behcet's disease who experienced life threatening airway obstruction after hemoptysis due to a large organized blood clot in left main bronchus. Urokinase(260,000 U), injected through a fiberoptic bronchoscope, totally dissolved the clot. No complications occurred.

A complete transection of left main bronchus was repaired by end to end anastomosis 5 months after the chest trauma in the Yeungnam University Hospital. The patient was a 36 years old male who had been injured bluntly by a heavy package on the left chest. The initial symptoms and signs were dyspnea, chest pain and subcutaneous emphysema on the left neck, but on admission at our hospital his chief complaint was only mild left chest discomfort. The preoperative chest X-ray findings 5 months after the trauma revealed total collapse of the left lung, deviation of trachea to the left, elevation of left diaphragm, abrupt discontinuation in the course of an air-filled left main bronchus and bronchoscopy showed that the left main bronchus was completely occluded, without any signs of inflammation, approximately 4 cm from the carina. The operation was performed through standard posterolateral thoracotomy incision at the fifth intercostal space. There was not any suppuration within the transected lung but plenty of white mucus which was removed by forceful suction. The transected bronchial edges were debrided and anastomosed primarily by end to end with interrupted nonabsorbable sutures. The suture line was reinforced with a pleural flap. The postoperative course was uneventful and pulmonary function following operation improved progressively and proved the delayed repair to have a reasonable decision.
