Airway mucus provides the protective functions such as lubrication, barrier, disposal of trapped materials, and humidification. In the normal state, the mucus do not interfere with Bas transport and the other vital functions of lung. In diseases such as asthma, bronchitis, and cystic fibrosis, the mucus hypersecretion was physiologically developed in the response of multiple neurohumoral mechanism system. And regardless of the mechanism, many clinical sequelae result from mucus hypersecretion: atelectasis, infection, increased airway resistance, increased work of breathing, increased cough with its resultant complication. And the condensation of mucus tv mucus hypersecretion can make the mucus plug by which bronchial obstruction is developed. We have experienced a 7 Pear-old male patient with recurrent pneumonic symtom, which the bronchial obstruction was developed by the impacted mucus plug on the bronchoscopic finding. We report this case with the review of literature.

In the presence of clinical evidence and chest roentgenogram suggestive of bronchogenic carcinoma, reliance is almost wholly placed on Papanicolaou staining of the sputum, bronchoscopy, and biopsy of peripheral lesion, together referred to as the "diagnostic triad". However, bronchography remains relatively non-utilized. Our experience with 56 bronchograms in which the modality of bronchial obstruction, distance to obstruction and reduction rate of caliber in leading bronchus were used in an attempt to explain underlying chest pathology and operability of bronchogenic carcinoma, indicated as follows: 1. The bronchographic findings in bronchogenic cancer consist of malignant bronchial obstruction in which the modality of obstruction is classified as abrupt type, conical type and compressed type in incidence of 50.0%, 23.2% and 26.8%, respectively. 2. Abrupt type of bronchial obstruction is more common in hilar type and particularly in squamous cell and undifferentiated cell type of bronchogenic cancer. In this type of obstruction the inoperability revealed in 57.8% and resectability in 17.8%. 3. Conical type of obstruction was a sign of most malignancy, in which 61.5% was undifferentiated cell type and 38.4% was squamous cell type. All this type of obstruction was inoperable even feasibility was presumed in simple roentgenograms. 4. Compressed type of obstruction was more common in peripheral type of bronchogenic cancer and showed 50.0% of resectability. 5. The distance from carina to bronchial obstuction revealed average 3.8cm in undifferentiated type, 5.76cm in squamous cell type and 7.60am in adeno cell type of carcinoma. 6. The reduction rate of caliber in leading bronchus to obstruction (mm per unit cm lenghth of leading bronchus) revealed average 2.15mm/cm in undifferentiated type 1.90mm/cm in squamous cell type and 1.13mm/cm in adeno cell type of carcnoma. 7. The reduction rate of caliber in leading bronchus showed 2.14mm/cm in inoperable cases and 1.42mm/cm in resectable cases. 8. The modality of bronchial obstruction and estimation of the reduction rate of caliber seemed to be a most reliable key-point to decide feasibility of resection.

기관지성형술은 폐기능이 저하되어 폐절제술이 불가능한 폐암 환자들에서 폐기능을 보존하면서 근치술을 시행할 수 있으므로 선택된 환자에서 널리 사용왔으며 동시에 폐쇄성 기관지 질환을 갖는 양성 환자들에서도 해부학적 교정을 통한 정상 호흡기능을 회복할 수 있는 수술로서 자리잡고 있다. 저자들은 1990년 4훨부터 1996년 4월가지 13명의 기관지 협착이나 폐쇄를 가진 환자들에서 2가지 방법의 기관지 성형술을 이용해서 치료하였다. 13명의 환자들은 남자 8명, 여자 5명이었고 평균연령은 43세로 19세부터 64세까지였다. 2가지의 기관지성형술은 자가늑연골편과 심낭편으로 제작한 첨포를 이용하는 기관지 확장성형술과 기관지 구역절제후 단단문합술로써 5명의 기관지 협착 환자에서는 확장 성형술을 적용하였으며 이들의 선행질환으로는 3례는 염증성 기관지확장증이었고 2례에서는 기관지 결핵이 동반된 기관지확장증이 있었다. 기관지 구역절제후 단단문합술은 8례의 기관폐쇄 환자에서 시행되었는데 선행질환으로는 기관지결핵이 6례, 외상 및 이물질에 의한 경우가 각각 1례씩 있었다. 수술과 연관된 사망은 없었으며, 합병증으로는 문합부의 재협착 례, 청포의 불안정으로 인한 장기간의 무기폐가 각각 1례씩 발생하였다. 결론적으로 기관성형술은 기관지 폐쇄나 혈착에 기인한 무기폐 환자에서 허탈된 폐의 생리적 기능을 정상으로 회복시키기 위해 시행될 수 있는 유용한술기이다.

기관지 폐색은 임상적으로 진단이 어려운 경우가 있는데 특히 대엽 이하나 소엽 기관지에 폐색이 일어날 경우엔 그 변화가 미미하기 때문에 더욱 그러하다. 저자들은 여러가지 원인에 의해 기관지 폐색과 협착을 일으킨 8예에서 연무흡입 폐환기스캔을 시행하여 폐환기스캔 소견을 분석하였고 진단적 유용성을 알아보고자 하였다. 8예중 7예는 기관지 폐색이었고 1예는 기관지 협착이었다. 연무흡입 폐환기스캔은 $^{99m}Tc$-phytate를 BARC nebulizer를 이용하여 시행하였다. 스캔 소견을 단순 흉부X선, 기관지조영술, CT, 그리고 기관지경 소견과 비교하였다. 전예에서 특징적으로 기관지 폐색 또는 협착 근위부에 짧고 약간 확장된 기관지 분절에 강한 연무침착 소견을 보였다. 또한 원위부에서는 폐실질의 환기결손 소견을 보였다. 이러한 소견은 기관지 폐색과 협착의 감수적이고 특이한 소견이며, 연두흡입 폐환기스캔은 특히 폐색부가 대엽 이하나 소엽 기관지일 경우에 더욱 유용할 것으로 생각된다.

Endobronchial tuberculosis is a serious disase because it frequently leaves airway obstruction as the complication, and the treatment of airway obstruction is generally troublesome. In the tumorous type of endobonchial tuberculosis, the bronchial patency is partially or completely compromised with lymph node contents when the necrotic focus of the lymph node ruptures into the bronchial lumen to form a bronchoglandular fistula. To investigate the transition of endobronchial lesion and to evaluate the therapeutic role of bronchoscopic electrocautery in the tumorous type of endobronchial tuberculosis, we performed electrocautery in addition to the combination chemotherapy with steroid and anti-tuberculous drugs in two cases which had airway obstruction proximal to lobar bronchus with the impairment of pulmonary function. We also treated another two cases only with chemotherapy and we have followed up four cases over a 36-month period. In cases that bronchoscopic electrocautery was done, the bronchial patency was completely restored and the impairment of pulmonary function disappeared just after cautery and these effects have remained for 12 months or more. But in cases of medical treatment only, bronchial stenosis was inevitable as the tumorous type of endobronchial tuberculosis changed to the stenotic type with fibrosis. It can be concluded that bronchoscopic electrocautery can nip the occurence of bronchial stenosis in the bud when it is applied in addition to combination chemotherapy with steroid and antituberculous drugs in the tumorous type of endobronchial tuberculosis.

The endobronchial hamartoma is a relatively rare benign tumor of the lung. The symptoms of the endobronchial hamartoma are produced by obstruction of the bronchus and its sequelae. This patient was 51 year old male and complained dypnea, cough and purulent sputum for 2 years. On bronchoscopic view, a yellowish pedunculated mass nearly total occluding right main bronchial lumen was found. Endoscopic biopsy revealed squamous cell metaplasia of the bronchial mucosa. The operation was done with the right pneumonectomy. The pathologic result of the operative specimen was endobronchial hamartoma arisen from the right upper lobe bronchus.

Mucoepidermoid carcinoma is one of bronchial adenoma which arising from submucosal gland or mucosal gland of lower respiratory tract. The symptoms of the tumor were produced by bronchial irritation and bronchial obstruction such as coughing, pneumonitis, and atelectasis. The malignancy potency of this tumor was determined by histologic pattern but high grade malignancy was uncommon and so distant metastasis was rare. Three treatment modality such as surgery, radiotherapy, chemotherapy were used for treatment but radiotherapy and chemotherapy were lesser effective than surgery. So Early and radical resection of tumor was recommended. Here we report one case of mucoepidermoid carcinoma which treated with radical resection.

Most of the patient with endobronchial tuberculosis have some degree of bronchial stenosis. however, a part of bronchial stenosis need aggressive treatment for the patency because of severe symptoms. The self-expendable metallic stents provide palliative treatment for narrowed airways where surgical resection is inadvisable. We experienced a successful left wedge pneumonectomy on a 29-year-old woman with obstruction of left main bronchus due to complication of the bronchial stent. She had inserted self-expendable metallic stents on left main bronchus of the tuberculous bronchial stenosis two times. There was no specific postoperative complication.
