Pulmonary hamartoma is relatively common among the benign tumors of lung, and is credited to Albrecht who In 1904 described a disorganized arrangement of tissue normally present In an organ. But hamartoma has rare incidence of total pulmonary tumors, and especially endobronchial origin is extremely rare. We have experienced three cases of pulmonary hamartoma Including one bronchial origin. First case was a 27 years old woman who had multiple hamartomas, located all in right middle lobe and middle lobectomy was performed. Second case, a 56 years old woman, had endobronchial hamartoma, l x l .5x l .8cm in size and located at right intermediate bronchus. Right pneumonectomy was Inevitable because of It`s proximal location near the hilum. Third case, a 55 years old man, revealed sclerosing hemangioma microscopically, 4x4x5 cm In size, in right lower lobe and right lower lobectomy was performed. Postoperative course of all of them were uneventful and discharged with good general condition on the ~ 4th to 26th day postoperatively.

Benign tumor of the lung are relatively uncommon and leiomyoma among these is one of the rarest tumors. Because of salient features as well as the location of the leiomyoma, which led to the destruction of the lung and subsequent pneumonectomy, the importance of early diagnosis should be emphasized. Recently, authors experienced a leiomyoma of left main stem bronchus with complete atelectasis of the lung, resected with left thoracotomy and transverse bronchotomy in a 58 year old male. The tumor resected was composed of dense interlacing spindle cells by hematoxilin-eosin and also trichrome stains. At repeated bronchoscopic examination postoperatively, one and three months later, there was no evidence of any residual or recurrent tumors. For the universal rarity of the leiomyoma in the bronchus or lung and also there is no report in the reviews of the Journal of Korean Thoracic and Cardiovascular Surgery since volume one, 1968, authors report a case with the foreign literature reviews.

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.

The remaining lung infarction is a rare but life-threatening complication after a thoracic operation and trauma. We report a case of this rare complication after the left upper lobectomy due to pulmonary aspergilloma. The infarction of the remaining left lower lobe occurred due to kinking of the pulmonary vessels after the left upper lobectomy and the completion pneumonectomy was performed in the post-operative second day. Therefore, prompt diagnosis and treatment may be necessary to prevent morbidity and mortality associated with pulmonary infarction from torsion of pulmonary artery and vein.

The usage of autosuture instruments and techniques in resection of bronchovascular structures gained increasing acceptance amongst surgeons in the recent years. The manipulation of these devices are simple, safe, and shortens operating time by avoiding numerous ties and sutures. We have been using autosuture instruments in most of pulmonary resections in Yongdong Severance hospital, and had a satisfactory results. However, we recently have experienced post-pneumonectomy rupture of left pulmonary vein on postoperative one day where the rupture site was in the border of left atrium and left pulmonary vein where the stapler was fired. The patient underwent emergency operation to control massive bleeding and successfully managed by left atrial suture.

Carcinosarcoma of the lung is a rare turner with an admixture of malignant epithelial(carcinomatous) and malignant mesenchymal (sarcomatous) components. Clinicopathologically, pulmonary carcinosarcoma has been divided into two types by its anatomical locations and growth nature, peripheral parenchymal and central endobronchial variants. We experienced an endobronchial carcinosarcoma that induced complete atelectasis of the right lung due to polypoid growing mass from the right upper lobe bronchus in a 67 year old male smoker. The patient underwent a successful right pneumonectomy. The tumor was composed of squamous cell carcinoma with variable sarcomatous differentiation into myogenous and undifferenciated sarcoma that demonstrated by immunohistochemical study. The patient has been doing well for the last seven months since the operation, without metastases or turner recurrence.

Background : Bronchial sleeve resection for centrally located primary lung cancer is a lung-parenchyma-sparing operation in patients whose predicted postoperative lung function is expected to diminished markedly. Because of its potential bronchial anastomotic complications, it is considered to be an alternative to pneumonectomy. However, since sleeve lobectomy yielded survival results equal to at least those of pneumonectomy, as well as better functional results, it became and accepted standard procedure for patients with lung cancer who have anatomically suitable tumors, regardless of lung function. In this study, from analyzing of occurrence rate of postoperative complication and survival rate, we wish to investigate the validity of sleeve resection for primary lung cancer. Material and Method : From January 1989 to December 1998, 45 bronchial sleeve resections were carried out in the Department of Thoracic Surgery of Seoul National University Hospital. We included 40 men and 5 women, whose ages ranged from 23 to 72 years with mean age of 57 years. Histologic type was squamous cell carcinoma in 35 patients, adenocarcinoma in 7, and adenosquamous cell carcinoma in 1 patients. Right upper lobectomy was peformed in 24 patients, left upper lobectomy in 11, left lower lobectomy in 3, right lower lobectomy in 1, right middle lobecomy and right lower lobectomy in 3, right upper lobectomy and right middle lobecomy in 2, and left pneumonectomy in 1 patient. Postoperative stage was Ib in 11, IIa in 3, IIb in 16, IIIa in 13, and IIIb in 2 patients. Result: Postoperative complications were as follows; atelectasis in 9, persistent air leakage for more than 7 days was in 7 patients, prolonged pleural effusion for more than 2 weeks in 7, pneumonia in 2, chylothorax in 1, and disruption of anastomosis in 1. Hospital mortality was in 3 patients. During follow-up period, bronchial stricture at anastomotic site were found in 7 patients under bronchoscopy, Average follow-up duration of survivals(n=42) was 35.5$\pm$29 months. All of stage I patients were survived, and 3 year survival rate of stage II and III patients were 63%, 21%, respectively. According to Nstage, all of N0 patients were survived and 3 year survival rates of Nl and N2 were 63% and 28% respectively. Conclusion: We suggest that this sleeve resection, which is technically demanding, should be considered in patients with centrally located lung cancer, because ttlis lung-saving operation is safer than pneumonectomy and is equally curative.

Purpose To evaluate the usefulness and effectiveness of bronchial occluders in the treatment of postoperative bronchopleural fistula (BPF). Materials and Methods The subjects of the study were six out of seven postoperative BPF patients who underwent surgery due to tuberculosis or lung cancer between 2009 and 2019. Each patient had a bronchial occluder inserted to treat BPF that occurred after surgery. Of the six patients, five had lung cancers and one had tuberculosis. Five were male and one was female; their ages ranged from 59 to 74 years, with an average of 69 years. The diagnosis of BPF was based on findings from bronchoscopy and CT, and treatment was initiated approximately 1 to 2 weeks after diagnosis. The technical and clinical success of the bronchial occluders in the treatment of BPF was evaluated. The study assessed the postoperative clinical effects of the occluders, survival duration, and additional treatments. Results All six patients were successfully treated. Clinical success was achieved in five patients, while partial clinical success was achieved in one; there was no clinical failure. No complications during the migration of the device or device perforations were observed. Two patients were diagnosed with BPF by CT, while four were diagnosed by bronchoscopy. Lobectomy, bilobectomy, and pneumonectomy were performed on two patients each. The periods between surgery and diagnosis ranged from 1 to 34 months; the average was 10 months. Four patients (59-103 days; an average of 80.5 days) died and two (313 days, 3331 days) survived. The causes of death were aggravation of the underlying disease (n = 2), pulmonary edema and pleural effusion (n = 1), and pneumonia (n = 1). Additional catheter drainage was performed in one patient, and a chest tube was maintained in two patients. Conclusion Bronchial occluders are useful and effective in the treatment of BPF after pulmonary resection.

A case is described in a girl who presented with recurrent life-threatening hemoptysis at the age of 18 months, and had been diagnosed as atrial septal defect with severe cardiomegaly which was presumed to result in pulmonary vein stenosis at the age of 6 months. Closure of atrial septal defect was associated with decreased heart size and improved pulmonary venous flow. However, recurrent life-threatening hemoptysis occurred during follow-up, Computed tomography scan demonstrated left pulmonary vein stenosis and extrinsic compression of the left bronchus by multiple soft tissue density-masses. Exploratory thoracotomy revealed single stenotic left pulmonary vein, and flat left main bronchus compressed by multiple hypertrophied lymph nodes, Unexpected endotrachial tube bleeding during left hilar dissection mandated to proceed to left pneumonectomy, The patient's postoperative course was uneventful. Follow-up chest roentgenography revealed acceptable left hydrothorax without mediastinal shifting, Nevertheless, a long-term follow-up is necessary.
