Bronchial foreign body is not a rare disease in children and it is urgently necessary to remove this foreign body from the airway to relive life or to prevent further damages and complications. But the innate small size of airways in infants makes it difficult to access by interventional methods such as intubation or bronchoscopy and etc. Laryngeal mask airway is a new way of method of airway management which is relatively recently introduced into medical practice. It gives way to access to airways without reducing the size of airway or incresing airway pressure during procedure through it and have many other advantages compared to the previous traditional endotracheal intubation, especially in infants. We successfully removed a case of bronchial foreign body, peanut, via laryngeal mask airway during fiberoptic bronchoscopy and by this method we can avoid the unnecessary tracheostomy in this 1 year old infant.

기도내 이물제거에 경직성 기관지경이 많이 이용되었으나 성인에서는 굴곡성기관지경을 이용하여 용이하게 시행할 수 있으며 다양한 기구를 사용하면 성공률을 높일 수 있다. 따라서 성인의 기도이물제거에 굴곡성기관지경을 우선적으로 사용할 수 있을 것으로 생각된다.

The intractable pneumothorax with continuous air leakage, emphysematous lung and high operative risk treated by selective bronchial occlusion has been seldomly reported abroad. The bronchus responsible for air leakage was occluded with such materials as fibrin glue, gelatin sponge and oxidized regenerated cellulose(surgicel). We performed selective bronchial occlusion by flexible fiberoptic bronchoscopy with gelfoam in two cases. There was no complication after the procedure; therefore, we report the treatment for intractable pneumo- thorax by bronchoscopy with gelfoam packing.

Background: As well as fiberoptic bronchoscopy, chest computerized tomographic scan can now differentiate the benign from malignant causes and the obstructive from non-obstructive causes of lung collapse. This study was designed to evaluate the usefulness of chest CT scan and fiberoptic bronchoscopy in the diagnosis of middle lobe syndrome. Method: We reviewed the clinical features, roentgenographic changes, pathologic findings and bronchoscopic findings in 16 patients with middle lobe syndrome who were admitted to Severance Hospital during period of January, 1987 through January, 1992. Results: The male to female ratio was 1:1. The most common symptoms were cough and sputums. Crackle was the most common physical finding. Underlying disease was lung cancer, pulmonary tuberculosis and endobronchial tuberculosis in 3 each other, benign stenosis in 2, lung abscess, broncholithiasis, bronchial chondroma, pneumonia and nonspecific inflammation in 1 each other. Conclusion: We conclude that the combination of chest computerized tomogram and fiberoptic bronchoscopy was most desirable for the diagnosis of middle lobe syndrome.

Since Ikeda in traduced flexible fiberoptic bronchoscope in 1968, use of bronchoscopy was expanded rapidly. Wide use of flexible bronchoscopy enabled us to get tissue diagnosis with more ease and safety. Authors analyzed 71 cases of tissue biopsy of 233 bronchoscopies from June '76 to. Jan. '78 and concluded as following : 1. 233 bronchoscopies af 20 Month duration, cases which needed tissue biopsy were 71 cases (30.5%). 2. Chief complaints af above cases are coughing, dyspnea, sputum, chest pain, hemoptysis in frequency. 3. Biopsy sites were as following in frequency: Rt.upper lobe, Lt. main bronchus, Lt. upper lobe, Rt. main bronchus, Lt. lower lobe. 4. The final diagnosis of biopsied cases were cancer 80%, tuberculosis 15%, and malignant mesothelioma, anthracosis, aspergillosis, were one case each. 5. Among 57 case of lung cancer, biopsy confirmed cases were 36 cases (63%). 6. Pathologic finding of 36 case of Biopsy confirmed lung cancer was as following: Squamous cell ca : 64% Anaplastic ca : 25% Adeno ca : 2.8% Unclassified: 2.8% 7. Bronchographies were done in 36cases (51%), one quarter of cases before biopsy, and three quarters of cases after biopsy. 8. Cytology was requested in 76% of cases with following results; PAP class V 15%, class IV 7.5%, class III 1.8%.

The bronchogenic cyst is not so rare in incidence, but it is rare for this cyst to cause compression of trachea and main bronchi. A 6-year old female child was evaluated for coughing, fever and left total atelectasis. This patient had a history of frequent upper respiratory symptom like bronchial asthma since 6month after birth. Fiberoptic bronchoscopy revealed external compression at distal trachea and both main bronchi. Computed Tomography revealed well demarcated homogeneous mass compressing distal trachea and main bronchi. The pathological examination showed bronchogenic cyst and this patient had uneventful recovery.

Leiomyoma is extremely rare benign tumor of the trachea. A case of leiomyoma of the trachea is described in a 36-year-old man. The patient had a brief history of asthma-like symptoms. Computed tomography of the chest revealed the ovoid lower trachea mass, which was occupying about 80% of the tracheal lumen. At fiberoptic bronchoscopy highly vascularized round mass was seen on the membranous portion of the lower trachea. The tumor was excised by segmental sleeve resection and end-to-end anastomosis of the trachea was performed. Postoperative course was uneventful and bronchoscopic findings showed clear healing of the anastomotic site.

Diffuse tracheobronchial amyloidosis is an uncommon form of pulmonary involvement, and causes prolonged cough, dyspnea, wheezing and repeated development of pneumonia. We report a case of diffuse tracheobronchial amyloidosis in 58-year-old woman that was traeted by repeated electrocautry under flexible fiberoptic bronchoscopy. The patient had a long-standing history of dyspnea and was admitted due to resting dyspnea, which was aggravated to impending respiratory failure after diagnostic procedures. We applied repeated electrocautry to the endobronchial amyloid tumors and successfully reduced bronchial stenosis and the pateint didn't feel dyspnea. We suppose that, in certain cases of tracheobronchial amyloidosis patients, endobronchial electrocautry would be a helpful procedure.

In contrast to juvenile laryngeal papillomatosis, which occurs most often in children and teenagers and is usually self limited, soliatry papillomas in adults are one of uncommon tumors of airway, and have a higher incidence of cancer. They are caused by the respiratory infection of human papilloma virus(HPV). They could spread to more distal airways and have a tendency of recurrence after limited surgical excision. Recently endoscopic therapies such as Nd-YAG laser, electrocautery, and cryotherapy provide extremely effective treatment modalities. We report a case of solitary tracheal papillomas in a 48 year-old man who presented with cough, scanty hemoptysis, and functional evidence of central airway obstruction. He was successfully treated by a Nd-YAG laser therapy via fiberoptic bronchoscopy under the local anesthesia.

A total of 322 patients with endobronchial tuberculosis (8.1%) out of 3,982 subjects who had a flexible fiberoptic bronchoscopic examination at the Department of Pulmonary Medicine of Hanyang University Hospital between the beginning of March 1982 and the end of April 1996 were included in this study. The peak incidence occurred in the second decade, and the male to female was 1 : 3.0. The barking cough with variable amounts of sputum was the most common chief complaint in 56.9% of the 313 patients. Other complaints included dyspnea, chest pain, fever, hemoptysis, and generalized weakness. Localized wheeze was heard over the chest in 16.9% of the 313 patients. Infiltration/consolidation was the most common roentgenographic finding of the chest in 64.2%. Bronchoscopically, hypertrophy with luminal narrowing was the most common findings in 32.3% of the 322 patients and left main bronchus was the most frequently involved in 24.0%. Using fiberoptic bronchoscopy allows not only substantial meaningful assessment of endobronchial tuberculosis but also makes a differential diagnosis of lung cancer in older patients. We need further evaluations of standard bronchoscopic classification of endobronchial tuberculosis, diagnostic accuracy of endobronchial tuberculosis by PCR, a large prospective study of effects of corticosteroids in endobronchial tuberculosis patients, and appropriate treatment of atelectasis by endobronchial tuberculosis.
