Background: Bronchial carcinoids account for approximately 2% of all pulmonary tumor and consist of typical carcinoids and atypical carcinoids. An atypical carcinoids is considered to be an intermediate form of tumor between a low-grade malignant typical carcinoid and a high-grade malignant small cell lung carcinoma. There is still controversy with regard to the extent of resection and the value of systemic adjuvant therapy in atypical carcinoids. We performed a retrospective review of our experiences at Severance Hospital. Material and Method: Between 1990 and 2000, 15 patients with bronchial carcioids were operated, and 5 of these had atypical carcinoids. Histologic diagnosis was established un the criteria of WHO/IASLC(1999). Result: There were 3 pneumonectomies, 11 lobectomies, and 1 segmentectomy. In typical carcinoids, one patient had regional lymph node metastasis, and 3 patients in atypical carcinoids had mediastinal lymph node metastases. Distant metastases developed in one patient of typical carcinoid, but developed in 4 patients of atypical carcinoids(p=0.0017). The 5-year survival rate in patients with atypical carcinoids was 20%, versus the 100% 5-year survival rate observed in patients with topical carcinoids(p=0.0039). Conclusion: In atypical carcincids, because of many lymph node metastases on diagnosis and a low long-term survival rate, lobectomy constitutes a mininal procedure. Adjuvant systemic therapy is recommended fur patients with lymph node and distant metastasis.

Video thoracoscopic surgery is a new modality that gains acceptance rapidly from thoracic surgeons. We have experienced two left lower lobectomies, one left upper lobectomy & one right upper lobectomy with using video thoracoscopy for the four patients with lung parenchymal disease from July 1992 to February 1993. The post-operative courses were uneventful. The final pathologic diagnosis were sclerosing hemangioma, adenocarcinoma, bronchiectasis, leiomyoma & the post-operative courses were short. These patients needed less analgesics because postoperative pain was reduced markedly, and hospitalization was shortened due to rapid recovery. We would like to prefer video thoracoscopic lobectomy to the lobectomy through standard thoracotomy in uncomplicated patients with simple pulmonary parenchymal diseases.

Percutaneous transthoracic fine needle biopsy has been widely used In the diagnosis of pulmonary lesions especially lung cancer. Onc of the rarest complication's is that malignant cells are implanted within the needle tract and developed a chest wall mass subsequently. Wc expcrlenccd a case of chest wall implantatio of lung cancer after percutaneous transthoracic floe needle biopsy. A 65-ycar old man had undergone bilobectomy (right upper lobe and right middle lobe)for squamous cell (·4rcinoma (TINOMO) of the lung. 60 days after percutaneous biopsy (48 days after operation), a tiny nodule (1 mm sized) was notcd at the right anterior chcst wall where the diagnostic fine needle biopsy had been performed before operation. This tiny mass was rapidly growing to 1.5 cm sized mass for 20 days. We carried out wide excision of chest wall mass and skin grafting, and confirmed squamous cell carcinoma histopathologically as same as the lung cancer.

Background: It is known that long-term survival rate in patients underwent bronchial sleeve lobectomy for primary lung cancer is at least equal to that in patients underwent pneumonectomy, and bronchial sleeve lobectomy is performed in patients with suitable tumor location even in patients have adequate pulmonary function. Sleeve pneumonectomy is performed when carina was invaded by tumor or tumor location was near to the carina. We performed this study to know our results of sleeve resection for primary lung cancer. Material and Method: We analyzed retrospectively the medical records of 45 patients who underwent sleeve lobectomy or sleeve pneumonectomy for primary lung cancer by one thoracic surgeon from May 1990 to July 2003 in Department of Thoracic & Cardiovascular Surgery, College of Medicine, Kyung Hee University. Follow-up loss was absent and last follow-up was performed in April 5, 2005. Kaplan-Meyer method and log-lank test were used to know long-term survival rate and p-value. Result: Mean age was 60 years old and male to female ratio 41:1. Histologic types were squamous cell carcinoma were 39, adenocarcinoma were 4, and others were 2 patients. Pathologic stages were I 14, II 14, and III 17 patients. Nodal stages were N0 23, N1 13, and N2 9 patients. Types of operation were sleeve lobectomy 40 and sleeve pneumonectomy 5 patients. Operative mortality was 3 patients and its cause was respiratory complications. Early complications were pneumonia 4, atelectasis 8, air leakage more than 7 days 6, and atrial fibrillation 4 patients. In 19 patients tumor was recurred. Local recurrence was 10 and systemic metastasis was 9 patients. Overall 5, 10-year survival rate were 54.2%, 42.5%. The 5, 10-year survival rates according to the pathologic stage were 83.9%, 67.1% in stage I, 55%, 47.1% in II, 33.3%, 25% in III, and significance difference was present between stage I and III. The 5, 10-year survival rate according to the lymph node involvement were 63.9%, 54.6% in N0, 53,8%, 46.5% in N1, 28.5%, 14.2% in N2, and significance difference was present between N0 and N2. Conclusion: Because bronchial sleeve lobectomy for primary lung cancer could be performed safely and shows acceptable long-term survival rate, it could be considered primary in case of suitable tumor location if complete resection is possible. Although sleeve pneumonectomy for primary lung cancer shows somewhat high operative mortality rate, it could be considered in view of curative treatment.

Sleeve lobectomy for bronchogenic carcinoma is an alternative to pneumonectomy. The extent and location of the tumor must be such that a sleeve procedure is feasible. The conservation of lung tissue benefits both compromised and uncompromised patients. From August 1988 to March 1989, five patients underwent sleeve lobectomy for bronchogenic carcinoma of the lung. The patients included four males and one female ranging in age from 52 years to 66 years. All patients were diagnosed as having squamous cell carcinoma. Operative procedures were right upper sleeve lobectomy in four cases and left upper sleeve lobectomy with pulmonary angioplasty in one case. Complications developed in one patient. An asthmatic attack necessitated ventilator support for one day. Bronchoscopic examinations were performed at two weeks and three months postoperatively in four patients. Anastomosis sites on all patients were intact, but in one case, nodules were noted. Pulmonary function tests were also checked at three months postoperatively, and showed good results. The reimplanted lobe or lobes contribute significantly to the overall remaining lung function. All patients are being followed up with satisfactory results, except one case of suspected local tumor recurrence. We think, therefore, that sleeve lobectomy is a safe and adequate procedure for patients with resectable lung cancer.

This is a case report of surgical management of a bilateral intralobar pulmonary sequestration with horseshoe lung presenting with frequent U I with productive sputum. Simple chest X-ray showed pneumonic consolidation and infiltration on both lower lobes, and chest CT revealed multiple cystic lesions compatible with pulmonary sequestration. The aortography demonstrated two anomalous systemic arteries arising from the thoracic aorta just above the diaphragm to both sequestrums. Left lower lobectomy was performed through the left thoracotomy with ligations and divisions of the both systemic feeding arteries to the left and right sequestrum, and division of the isthmic portion of horseshoe lung without removal of right sequestrum. The patient was discharged on the postoperative loth day and followed-up till now without any sequelae and symptoms of residual right sequestration. The recent follow-up chest CT 5 months after the operation revealed spontaneous regression of the residual right sequestrum. Authors would suggested that only division of aberrant artery to sequestrum without lobectomy may be applied in uncomplicated ca e of intrapulmonary seqilestration.

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.

Necrotizing bronchial aspergillosis usually occurs in the immumocompromised host. Aspergillus invades bronchial epithelium and forms endobronchial mass or endobronchial stenosis. A 78-year-old male patient with diabetus mellitus complaining of dyspnea and cough was admitted to our hospital. Plain chest X-ray and chest computed tomogram showed a large endobronchial mass and total collapse of left upper lobe of the lung. Bronchoscopic biopsy of the endobronchial mass revealed chronic inflammation. To confirm the endobronchial mass, we performed sleeve lobectomy of left upper lobe of the lung. Histologically the mass was diagnosed as necrotizing bronchial aspergillosis. We report a case of necrotizing bronchial aspergillosis in an elderly man who has diabetus mellitus with review of the literature.

An eight-year-old boy was referred to our hospital with cough and high fever. His past medical history included a small sized ventricular septal defect (VSD) at birth. Transthoracic echocardiography disclosed a 10 x 6 mm vegetation on tricuspid valve, a small VSD and the moderate tricuspid valve insufficiency were found. Blood cultures grew methicillin-resistant staphylococcus aureus. Despite proper antibiotic therapy, fever was not controlled and his course was complicated by pulmonary infarction. The patient simultaneously underwent pulmonary resection and open heart surgery. Through the median sternotomy we performed open thrombectomy and lobectomy (right lower lobe) at first, and then vegetectomy, tricuspid valve repair, and direct closure of VSD were done under cardiopulmonary bypass.
