The foreign bodies in air way require the emergent managements in the otolaryngolagic field, and if the diagnosis and treatment were delayed, unexperted catastrophic situations may occur. The authors had analysed the airway foreign bodies of 50 cases which had been ventilating bronchoscopy. 1. In sex distribution, male to female ratio was 2.8 : 1. 2. In the age incidence, 58% were 1∼5 yrs. 3. Frequent symptoms, were coughing (68%), dyspnea (52%) and cyanosis (18%) in the oder. 4. The significant foreign body histories were noticed in 33 cases (66%). The initial misdignosis were 28%, and af which 57.1% were URI 5. In auscultation, decreased breathing sounds were noticed in 46%, wheezing were 24% and 26% were with in normal limit. 6, In duration af lodgement, 68% were removed within 24 hours. 7. Tracheostomy were performed in 24%, and foreign bodies were removed by ventilating bronchoscope in 72%. 8. The foreign bodies were vegetable (46%), metal (28%), plastic (18%) and fish bone (8%). 9. The prevalent site of foreign body were right main bronchus, left main bronchus, and trachea in the order mentioned.

Background : The development of bronchoscopic equipment along with the precision of radiographic techniques had reduced the mortality rate of patients with tracheobronchial foreign bodies but has been no change in the incidence of tracheobronchial foreign bodies since their introduction. The aim of this study was to assess the clinical characteristics of a tracheobronchial foreign body aspiration and to evaluate the efficacy of the treatment modality in children and adults. Methods : This is a retrospective review of 64 patients who underwent bronchoscopic procedures for the treatment of aspirated foreign bodies from December 1994 through March 2004 at the Chonnam national university hospital. Results : There were 47 males and 17 females, aged from 1 month to 78 years. Most of the patients had no underlying illness except for one patient with a cerebrovascular accident that contributed to the foreign body aspiration. The most common symptom was cough, which was noted in 54 patients (84.3%). The other presenting symptoms were dyspnea (48.8%), fever (20.3%), sputum (14%), vomiting (7.8%), and chest pain (4.6%). Those whose tracheobronchial foreign bodies were diagnosed more than 2 days after the aspiration (21 patients) were more likely to have pneumonia than those whose foreign bodies were diagnosed within 2 days (p = 0.009). Foreign bodies were visualized in the plain chest radiographs in 12 cases (18.8%), while others showed air trapping (21, 32.8%), pneumonia (15, 23.4%), atelectasis (7, 10.9%), and normal findings (9, 14.1%). The foreign bodies were more frequently found in the right bronchial tree (36) compared with the left bronchial tree (22, p = 0.04). In order to remove the foreign bodies, twenty (31.2%) cases were removed using flexible bronchoscopy, while 42 (65.6%) and 2 (3.2%) cases required rigid bronchoscopy and surgery, respectively. Conclusions : Tracheobronchial Foreign body aspiration had a bimodal age distribution in the infancy and old age around 60 years. They were found more frequently in the right bronchial tree. In addition, patients whose foreign bodies were diagnosed more than 2 days after the aspiration were more likely have a infection. Rigid bronchoscopy is the procedure of choice for uncooperative children and for those with foreign bodies lodged deeply in the small bronchial tree.

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.

Airway difficulties are a major concern for anesthesiologists. Even though fiberoptic intubation is the generally accepted method for management of difficult airways, it is not without disadvantages-requires patient cooperation, and cannot be performed on soiled airway or upper airways with pre-existing narrowing pathology. Additionally, fiberoptic bronchoscopy is not available at every medical institution. In this case, we encountered difficult airway management in a 71-year-old man with a high Mallampati grade and a thick neck who had undergone urologic surgery. Several attempts, including a bronchoscope-guided intubation, were unsuccessful. Finally, blind nasal intubation was successful while the patient's neck was flexed and the tracheal cartilage was gently pressed down. We suggest that blind nasal intubation is a helpful alternative in difficult airway management and it can be a lifesaving technique in emergencies. Additionally, its simplicity makes it a less expensive option when advanced airway technology (fiberoptic bronchoscopy) is unavailable.

Endoscopic removal is acceptable for the treatment of endotracheal/endobronchial mass, because it is less invasive in high-risk patients and a conservative procedure for benign tumors. Two benign tumors in the lumen of the trachea (pure lipoma) and in the intermediate bronchus (hamartoma) were completely eradicated by our procedures, which involved diathermic snaring and residual mass removal with biopsy forceps under the guidance of fiberoptic bronchoscopy. No tumor recurrence was evident after extended follow-up (6 years for endotracheal lipoma and 2.5 years for endobroncheal hamartoma). Our method is safe and less invasive for the patient and provides the surgeon with better view during procedure.

Aspiration of foreign bodies into the tracheobronchial tree is unusual in adults and it may result in Proximal airway obstruction and acute life-threatening asphyxia. It can be diagnosed by history of aspiration or visualizing the foreign body by chest roentgenogram or bronchoscopy. But it is rarely considered in adults with subacute or chronic respiratory symptoms without a definite history which suggests an aspiration. A 70-year-old woman was admitted to the hospital due to productive cough for two months and dyspnea which aggravated since the day before admission. Chest X-ray showed Pneumonic infiltration on left upper lobe and right lower lobe. Despite several days of conventional therapy, the patient complained of severe dyspnea and wheezing. We performed chest CT to rule out endobronchial stenosis, and it revealed the narrowing of left main stem bronchus compatible with endobronchial tuberculosis. Fiberoptic bronchoscopy for confirmation disclosed a $3.2{\times}0.7{\times}0.2$cm sized foreign body located longitudinally at the left main stem bronchus. We removed it with alligator forcep and it proved In be a piece of artificial denture. The patient remembered losing it while severe coughing on the day before admission. The microscopic examination of bronchial washing fluid revealed numerous acid fast bacilli. After removal of the foreign body, the patient showed marked improvement in symptom and pulmonary function test. Here we report a case of Pulmonary aspiration of foreign body which is confused with endobronchial tuberculosis with a review of the literature.

Bronchial carcinoid tumor accounts for less than 5% of all primary lung tumors in adults. Although surgical resection is the treatment of choice, here we report a case of bronchial carcinoid tumor treated with flexible bronchoscopic resection. A 19-year-old-man presented with a history of wheezing with dyspnea for six months. A simple chest x-ray showed no abnormal findings, but a pulmonary function test showed a moderate obstructive lung disease pattern without a bronchodilator response. A computed tomogram of the thorax revealed an enhanced $15{\times}12$ mm nodule in the left main bronchus. Bronchoscopic examination showed a polypoid mass with a stalk in the left main bronchus, which almost completely occluded the left main bronchus. Histopathology of the resected specimen revealed a bronchial carcinoid tumor. We treated the carcinoid tumor with a flexible bronchoscopic resection. During the follow up period of 6 months, the previous tumor didn't relapse. Initial bronchoscopic resection should be considered when bronchial carcinoid tumor can be approached by bronchoscopy.

Endobronchial metastasis of leiomyosarcoma is rare, but it can cause life-threatening complications, such as massive hemoptysis, respiratory failure or even death. The development of new endoscopic modalities allows for effective endobronchial management. We report three patients with endobronchial metastases from advanced leiomyosarcomas which caused bronchial obstruction. The bronchoscopic examinations revealed masses obstructing the left main bronchus in all three patients. After removing the endobronchial tumor via interventional bronchoscopy, there was symptomatic and radiologic improvement. Moreover, the patients were able to undergo additional palliative chemotherapy. Therefore, endobronchial management of endobronchial tumors should be considered in the treatment of endobronchial metastasis, even in patients with advanced malignancies.

Tracheal Stenosis after Tracheostomy Treated Successfully with Papillotome Electrocautery A 39-year-old woman presented with symptoms of dyspnea. Ten years previously, she had received a tracheostomy because of the decision to not continue taking an anticonvulsant drug. Presently, chest computed tomography showed diffuse stenosis and focal web at the cervical trachea. We performed bronchoscopy and found a two-thirds reduction of the upper trachea due to the web-like fibrotic stenosis. Papillotome electrocautery removed the stenotic lesion. Endobronchial electrocautery is a valuable tool with potential for therapy of an endobronchial obstructing airway lesion. We report this case to introduce the successful treatment with papillotome electrocautery.

Capillary hemangioma of the tracheobronchial tree is an extremely rare benign tumor in adults, especially those located in the bronchus. Characteristics and treatment of capillary hemangiomas of adult tracheobronchial trees have not been well known. We present a 61-year-old man with hemoptysis, which was caused by a small tiny nodule in the left lingular segmental bronchus. The nodule was removed by a forcep biopsy, via flexible bronchoscopy, and it was revealed to be capillary hemangioma. A small isolated endobronchial capillary hemangioma can be treated with excisional forcep biopsy, but a risk of massive bleeding should not be overlooked.
