We report a bronchoesophageal fistula that treat with bronchial stent insertion and histoacryl injection. A 52-year-old man with esophagel cancer was transferred for dysphagia management. At the CT scan that underwent on admission, esophageal cancer with multiple lymph node metastasis was observed. At the gastroduodenoscopy and contrast study, bronchoesophageal fistula was observed. Recurrent stent insertion treatment was failed, and then, By the broncoscopy, covered stent was inserted to right bronchus, and By the endoscopy, fibrin glue and histoacryl was injected in the fistula opening. At the contrast study, contrast leakage was not observed, and the patient was discharged. But, at the 14 days after discharge, the patient was admitted to the emerency room because of cough symptom whenever he eat food. The patient was diagnosed with aspiration pneumonia, we were determined that it is unable to oral intake. The patient received a jejunostomy and antibiotic treatment for aspiration pneumonia. He was discharged after symptomatic improvement.

Objectives : Multiple lung cancers and/or precancerous lesions can be developed because many bronchi are exposed to carcinogens simultaneously according to the concept of "Field Cancerization". We had performed a careful bronchoscopic examination and analysed the patients of double bronchial lesions who received the separate pathologic evaluation. Methods : We studied 21 patients of double bronchial lesions among 1855 patients of bronchoscopic examination from April 1990 to December 1993 in Korea Cancer Center Hospital. We classified the patients into three groups(double malignancies of different histology, double malignancies of same histology, and combination of malignant and benign lesions) and analysed the histologic type, location, radiologic findings, and clinical parameters. Results : Among 21 patients, six patients had double malignancies of different histology, eight had double malignancies of same histology, and seven had combination of malignant and benign lesions. Out of 14 double malignant cases, 11 cases are considered as synchronous multiple primary lung cancers. Combination of squamous cell carcinomas was found in 5 cases, combination of small cell carcinoma and squamous cell carcinoma was found in 4 cases. Combination of adenocarcinoma and squamous cell carcinoma and combination of squamous cell carcinoma and poorly differentiated carcinoma were found in 1 case respectively. All patients of synchtonous multiple primary lung cancers were male and had long smoking history(average 40 pack years). Among 21 cases of double bronchial lesions, only one lesion could be detected by prebronchoscopic radiologic examination including chest CT in 15 cases. Conclusions : The presence of double bronchial lesions including multiple primary lung cancers and the limitation of radiologic examination to detect early bronchial lesions encourage us to examine the whole bronchi carefully and to perform pathologic evaluations.

Background: Even though lung cancer has become a major cancer in Korea, national survey for lung cancer has not been available except several reports from individual hospitals. Methods: Korean Academy of Tuberculosis and Respiratory Diseases retrospectively investigated the characteristics of lung cancer diagnosed from January 1997 to December 1997 at general hospitals over 400 beds. Results: Among 3,794 patients, 76.8% are smokers and 89.8% of male patients are smokers. Squamous cell carcinoma is the leading type of lung cancer(44.7%) followed by adenocarcinoma(27.9%). Smoking rate in adenocarcinoma was significantly lower than in squamous cell carcinoma and small cell cancer. Cough is the most common symptom, however, 7.2% are asymptomatic. Bronchoscopic biopsy has a main role in the diagnosis of squamous cell carcinoma and small cell cancer but percutaneous needle biopsy has more important role in adenocarcinoma. Two-thirds of NSCLC patients were found in unresectable advanced stages. Conclusion: In contrast to other countries, squamous cell carcinoma is still the most frequent type of lung cancer. High proportions of smoker and advanced, unresectable lung cancer urge us to develop the program for cessation of smoking and early detection.

Background : Bronchioloalveolar carcinoma (BAC) has been reported to diveres spectrum of chinical presentations and radiologic patterns. The three representative radiologic patterns are followings ; 1) a solitary nodule or mass, 2) a localized consolidation, and 3) multicentric or diffuse disease. While, the localized consolidation and solitary nodular patterns has favorable prognosis, the multicentric of diffuse pattern has worse prognosis regardless of treatment. BAC presenting as a solitary pulmonary nodule is often misdiagnosed as other benign disease such as tuberculoma. Therefore it is very important to make proper diagnosis of BAC with solitary nodular pattern, since this pattern of BAC is usually curable with a surgical resection. Methods : We reviewed the clinical and radiologic features of patients with pathologically-proven BAC with solitary nodular pattern from January 1995 to September 1996 at Samsung Medical Center. Results : Total 11 patients were identified. 6 were men and 5 were women. Age ranged from 37 to 69. Median age was 60. Most patients with BAC with solitary nodular pattern were asymptomatic and were detected by incidental radiologic abnormality. The chest radiograph showed poorly defined opacity or nodule and computed tomography showed consolidation, ground glass appearance, internal bubble-like lucencies, air bronchogram, open bronchus sign, spiculated margin or pleural tag in most patients. The initial diagnosis on chest X-ray were pulmonary tuberculosis in 4 patients, benign nodule in 2 patients and malignant nodule in 5 patients. The FDG-positron emission tomogram was performed in eight patients. The FDG-PET revealed suggestive findings of malignancy in only 3 patients. The pathologic diagnosis was obtained by transbronchial lung biopsy in 1 patient, by CT guided percutaneous needle aspiration in 2 patients, and by lung biopsy via video-assited thoracocopy in 8 patients. Lobectomy was performed in all patients and postoperative pathologic staging were $T_1N_0N_0$ in 8 patients and $T_2N_0M_0$ in 3 patients. Conclusion : Patients of BAC presenting with solitary nodular pattern were most often asymptomatic and incidentally detected by radiologic abnormality. The chest X-ray showed poorly defined nodule or opacity and these findings were often regarded as benign lesion. If poorly nodule or opacity does not disappear on follow up chest X-ray, computed tomography should be performed. If consolidation, ground glass appearance, open bronchus sign, air bronchogram, internal bubble like lucency, pleural tag or spiculated margin are found on computed tomography, further diagnostic procedures, including open thoracotomy, should be performed to exclude the possiblity of BAC with solitary nodular pattern.

Background: Emergency airway access is essential when a patient has dyspnea that's due to tracheal or bronchial obstruction. Such methods as laser therapy and PDT are now being used for the treatment of tracheal obstruction that's due to benign diseases or nonsurgical malignant diseases. Cryotherapy is a method that uses extreme hypothermia for freezing a tumor to cause necrosis. In this study, we have evaluated the clinical effectiveness of performing endobronchial cryoablation through a flexible bronchoscope. Material and Method: 10 patients with tracheal obstruction that was due to endotracheal tumors were evaluated between May 2005 and May 2007. Eight were male and the mean age of the 10 patients was $59.4{\pm}18.4$ years. Three cases of tracheal obstruction were due to benign tumors and 7 were due to malignant tumors. The obstruction sites were 3 at the trachea, 3 at the carina and 4 at the bronchus. A flexible bronchoscope was inserted and the tumor was eliminated using a flexible cryoprobe. Follow up bronchoscopy was performed at 1 week and 1 month after cryoablation, and then we evaluated the decrease of dyspnea, the improvement of the performance and the complications of the procedures. Result: Complete remission was achieved in 4 patients and partial remission was achieved in 6 patients. Complications such as hemoptysis (100%), and cough (50%) were noted. Hemoptysis was spontaneously resolved in 3 to 8 days (mean: 4.9 days). A decrease in dyspnea and improvement in the performance was noted in all patients. Conclusion: Endobronchial stenosis plays a detrimental role in the life quality of a terminal cancer patient. Due to its simplicity and effectiveness for controlling bleeding, endobronchial cryoablation is considered to be a safe method that is clinically applicable to a wide range of tumors, including the removal of large tumors. We concluded that endobronchial cryoablation through a flexible bronchoscope is a safe, effective method for treating tracheobroncheal obstructions.

Pulmonary hamartoma is a common benign tumor of the lung, but endobronchial hamartoma is a rare tumor. Although bronchoscopic rcemoval or removal by bronchotomy or sleeve resection with preservation of the lung may be possible, when irreversible lung damage has occurred because of chronic obstruction and pneumonitis, pulmonary resection may be indicated. We herein report a case of endobronchial hamartoma which was treated by left upper lobectomy. A 42-year-old female with 3-week history of cough and left chest pain visited our hospital. Bronchoscopy showed total occlusion of the orifice of the left upper lobe bronchus by a lobulated endobronchial tumor and bronchoscopic biopsy was failed due to bleeding. A left upper lobectomy was performed because of severe consolidation of the left upper lobe by chronic obstruction. The patient was discharged on postoperative 14th day.

Tracheal tumors are uncommon comprising less than 0.1% of all malignancies. Metastatic tracheal tumors, especially from the extrathoracic sites, are exceedingly rare. Ovarian cancer tends to metastasize to the serous cavities and the lymph nodes. One large autopsy study reported tracheal involvement in 1% of patients who had died from ovarian cancer. Other studies have not mentioned tracheal involvement at all. Since the main symptoms of cough, hemoptysis, or wheezing are nonspecific, patients may be initially treated for other conditions including asthma or bronchitis. Here we describe a metastatic tracheal tumor from an ovarian carcinoma that was initially treated for bronchial asthma.

Lung parenchyma is a common organ for metastases of extrathoracic tumors, but endobronchial metastasis is very rare. In this report, we present a case of endobronchial metastases from renal cell carcinoma (RCC), and this was managed by performing operative resection. A 63-year-old man presented with frequent dry cough; he had previously undergone left nephrectomy and postoperative chemotherapy for grade 2 RCC eight years ago. Computed tomography and bronchoscopy showed an endobronchial tumor from the left lower lobe bronchus to the second carina, and this mass was diagnosed as a necrotic tissue with chronic inflammation at biopsy. During the operation, the mass was revealed to be a metastatic renal cell carcinoma on the frozen section diagnosis and there was no mucosal invasion on the resection margin of the left lower lobe bronchus. We performed lobectomy of the left lower lobe with systemic dissection of the mediastinal lymph nodes. The final histopathologic diagnosis of the endobrochial mass was metastatic RCC and any mediastinal lymph node metastasis was not found. The patient was discharged on postoperative day 10 without any postoperative complications.
