The omental pedicle flap[OFF] has been used for management of complicated problems in various fields of cardiovascular surgery. Its unique properties of enhancing neovascularity, relieving lymphedema, providing fibroblasts to promote healing, providing soft tissue coverage, & functioning in the face of existing infection make it ideal in managing many of the more complicated problems facing the thoracic surgeon. We have used omental pedicle for colosing of the bronchial fistula R esophageal fistula with filling the adjoining cavity after pneumonectomy. The successful closure of the bronchial stump with OFF were obtained in 2 cases, but one case was failed who was suffered from the esophageal fistula. The primary operation in each cases were right pleuropneumonctomy for tuberculous empyema in 2 cases & left pneumonectomy for chronic empyema in 1 case, We believe that the OFF is effective for closing fistula due to postoperative empyema k plombage procedures for dead space of infected thoracic cavity.

Lung cancer is a fatal disease, highlighting the importance of research on related topics, including surgery for lung cancer. However, systematic research analyzing surgery on a national scale is limited. This study aimed to investigate the research on lung cancer using nationwide data in South Korea and to analyze trends in lung cancer surgery, including its clinical implications. Published articles and data from the Korean National Health Insurance database were used. Although the incidence and mortality of lung cancer have been improving, it is predicted to be the most common and fatal type of cancer in South Korea in 2021. The number of surgical procedures for lung cancer is increasing, especially among women, those ≥76 years of age, residents of non-metropolitan cities, and middle-income patients. Lobectomy and sublobectomy, including segmentectomy, are increasingly common. However, the proportion of pneumonectomy relative to other procedures is not increasing. Surgery has shown a reasonable survival rate, especially after lobectomy, but survival remains poor in patients ≥76 years of age who undergo pneumonectomy. The frequency of lung cancer surgery is increasing concomitantly with various socioeconomic changes. Lobectomy has become increasingly common, and the clinical results of surgery are satisfactory. Further research on the changing composition of surgical candidates is required.

Mediastinum is a very rare primary site of liposarcoma. In general, wide surgical excision with adequate resection margin is the treatment of choice for lipesarcoma. We experienced a case of liposarcoma in a 24 year-old male who complained of dyspnea and chest discomfort. Symptoms had been developed a month before admission, and the intensity had been gradually increased. He visited another general hospital, and there he received left closed thoracostomy because hemothorax was suspected. Afterwards, he was transferred to our hospital without a specific diagnosis, on review of outside chest computed tomography film, mass shadow was detected in the mediastinum. For the further evaluation, we checked the chest sonography and chest magnetic resonance imaging. MRI showed 10 cm sized mass contacted with pulmonary artery trunk and left main pulmonary artery. The radiologist strongly suggested sarcoma. On the 4th day after admission, we performed emergent exploratory left thoracotomy for hematoma evacuation because mediastinal shifting progressed and heart rate was increased. Biopsy confirmed that the evacuated materials were extraskeletal myxoid chondresarcoma, so we performed extrapleural left pneumonectomy including diaphragm and a part of the pericardium. The final pathologic diagnosis was myxoid/round cell liposarcoma. He was discharged without complication and systemic chemotherapy was scheduled to begin 2 month later. During chemotherapy, local recurrence and peritoneal metastasis developed, and he died 10 month after the surgical excision. We report this case with reviewal of literature.

From August 1979 to August 1995, 73 consecutive patients with various pulmonary diseases underwent pneumonectomy Underlying diseases were lung cancer(53 cases), pulmonary tuberculosis(10 cases), bronchiectasis(4 cases) and others(6 cases). Operative mortality and complication rate for 73 patients and respiratory capacity for 53 patients at postoperative 6 months were measured, and statistically analysed for the influencing factors. The influencing factors on prognosis included age, sex, pathologic finding (benign or malignant), associated diseases, preoperative pulmonary function test and operation time. The statistically significant factors for operative mortality were preoperative MW(% prep)(P=0.013) and operation time(P=0.009). The factors influencing operative complication was infectious disease (P=0. 015), and for respiratory capacity a postoperative 6 months, preoperative FVC(%. prod) (PED.0018), FEVI(%. prod)(P=0.0024), and MW(%. prod) (P=0.004)) were statistically significant factors. The preoperative FVC(%. tyred), FEVI(% . prod) and MW(%. prod) should be measured exactly. We conclude that preoperative lung function, cardiovascular and nutritional status, postoperative care and infection prevention were important factors to decrease the operative mortality and complication as well as to increase respiratory capacity.

Background: To assess the outcome of pulmonary resection in the management of hemoptysis caused by benign inflammatory lung disease. Material and Method: A longitudinal cohort study of 45 consecutive patients who were presented with hemoptysis and were treated with pulmonary resection from January 1995 to May 2004. The predictive preoperative risk factors of morbidity and recurrence of hemoptysis were analyzed. The mean age of the patients was 47.1 years. The mean follow-up was $35\pm34$ months. Result: The overall hospital mortality rate was $4.4\%(2/45)$. Postoperative complications occurred in 8 patients $(18.6\%)$. Complications were more common in patients who received blood transfusion than non-transfused patients (p=0.002). Patients with tuberculous destroyed lung disease had more amount of preoperative hemoptysis (p=0.002), more probability of transfusion (p=0.001), more probability of undergoing pneumonectomy (p=0.039) and more probability of postoperative morbidity. Patients of undergoing pneumonectomy had more probability of reoperation due to postoperative bleeding (p=0.047). Hemoptysis recurred in five patients but three had been subsided and two sustained during follow-up. A latter two patients had been prescribed with antituberculosis medication due to relapse of tuberculosis. Conclusion: A tuberculous destroyed lung disease has a higher rate of postoperative morbidity than other inflammatory lung diseases. A pneumonectomy in patients of inflammatory lung disease should be performed with great caution especially because of postoperative bleeding. Future study with longer and larger follow-up might show the reasons of recurrence of hemoptysis.

Benign lung tumors have been considered as relatively rare disease, which comprise approximately 8 to 15% of all solitary pulmonary lesions that are detected radiographically. We clinically analized 30 cases of benign lung tumors underwent the operation from Jan. 1970 to Aug.1991 in the department of thoracic and cardiovascular surgery, Catholic University Medical College. We adopted the classification presented by the World Health Organization[WHO], modified from Liebow, and added benign mesothelioma. There were 11 males & 19 females ranging in age from 2 years to 68 years old % the mean age was 38 years old. Of all 30 benign lung tumors, hamartomas [14 cases, 49%] were the most common & followed by hemangiomas [9 cases, 30%], 3 cases of benign mesotheliomas % a case of teratoma, papilloma, arteriovenous malformation and inflammatory pseudotumor. 14 cases of tumors were asymptomatic & were incidentally detected by plane chest x-ray In other cases, chief complaints at admission were coughing, chest discomfort, dyspnea, hemoptysis, and fever. Diagnosis were made by pathological examination; exploratory thoracotomy in 23 patients[76.7%], bronchoscopy in 4 patients and percutaneous needle aspiration biopsy in 3 patients. Precisely, preoperative diagnosis for confirmation of benign lung tumor was made only in 7 cases[23.6%]. Tumors were located on Rt.side[24 cases], especially Rt. middle lobe, and Lt.side[6 cases]. Operation methods were as follows: 21 cases [70%] of lobectomy, 2 cases of segmentectomy, 2 cases of wedge resection, 1 case of pneumonectomy, 1 case of bronchotomy, 2 cases of wedge resection, 1 case of pneumonectomy, 1 case of bronchotomy removal of the endobronchial hamartoma which located at the rt. main stem bronchus and 3 cases of complete resection in benign mesotheliomas. There were no operative death. The post operative complications were developed in 3 cases; post pneumonectomy empyema, wound infection and atelectasis. In conclusion, benign lung tumors must be histologically diagnosed to confirm of benignity and to provide limited resection for preservation of the lung tissue, whenever possible.

We have performed surgical operations for 184 primary lung carcinomas over a 10 year period from December, 1979 to December, 1990 at the department of Thoracic and Cardiovascular Surgery, Yonsei University College of Medicine, Seoul, Korea. We have reviewed 77 cases confirmed to be dead in the post-operative follow-up period among 184 cases. There were 68 males and 9 females [M: F=7.56: 1], with 76.62% ranging between 50 to 70 years old There were 50 cases[64.94%] of squamous cell carcinoma, 15[19.48%] of adenocarcinoma, 4[5.19%] of large cell carcinoma, 4[5.19%] of mixed cell carcinoma 3 [3.90%] of small cell carcinoma % 1 case of bronchoalveolar cell carcinoma. There were 25 cases[32.47%] in stage I, 12 [15.58%] in stage II 32 [41.56%] in stage IIIa and 8 [10.39%] in stage IIIb according to the new international staging system for lung cancer. The operative methods were left pneumonectomy in 38 cases, right pneumonectomy in 21, bilobectomy in 5, lobectomy in 12, and wedge resection in one case.ase. There were 9 operative mortalities; one case by bleeding, 5 cases by respiratory failure, one case by bleeding & renal failure, one case by empyema thoracis with BPF and one case by brain metastases. The actuarial mean survival length was 14.636$\pm$18.188months overall and 16.441$\pm$18. 627months in 68 cases excluding 9 operative deaths. The actuarial mean survival length was 18.568$\pm$11.057 months in 43 squamous cell carcinomas, 14.385$\pm$11.057 months in 14 adenocarcinomas, 10.250$\pm$8.884months in 4 large cell carcinomas and 12.250$\pm$17.193months in 4 mixed cell carcinomas. The actuarial mean survival length was 14.051$\pm$16.963months in 59 pneumonectomy cases, 15.200$\pm$12.478 months in 5 bilobectomy cases, 18.417$\pm$26.026months in 12 lobectomy cases. The actuarial mean survival length was 28.952$\pm$25.738months in 22 stage I cases, 19. 455$\pm$16.723months in ll stage II cases, 8.633$\pm$6.584months in 29 stage IIIa cases and 6. 167$\pm$4.355months in 6 stage IIIb cases.

Untreated massive hemoptysis, especially in patients with tuberculous-destroyed lung, is a serious complication resulting in considerable morbidity and mortality. We report a case of a patient who had active tuberculosis and a destroyed left lung with massive bleeding. He was transferred to our clinic with intubation of a right-sided Robertshaw double lumen tube and right upper lobe collapse likely due to tube malposition that was presented on chest X-ray. Because hemoptysis had persisted after bronchial arterial embolizaton, we replaced the double lumen tube with a conventional endotracheal tube and inserted an endobronchial blocker into the left main bronchus through an endotracheal tube guided by bronchoscopy to prevent aspiration of blood into the right lung. Left pneumonectomy was performed and hemotpysis was ceased. We suggest that the use of an endobronchial blocker followed by surgery may be a safe and effective modality of treatment in patients with persistent bleeding after bronchial arterial embolization.

Ten cases of the right middle lobe syndromes were experienced. Nine out of ten were treated surgically, six-right middle lobectomy, one-right middle and lower lobectomy, one-right middle lobectomy and decortication, one-incidental right pneumonectomy. Pathologic diagnosis were tuberculosis in five, bronchiectasis in two, organizing pneumonia in one, and foreign body granuloma in one. There were three postoperative complications, postoperative empyema-1, pleural effusion-1, pneu-monia-1. The surgical candidates for middle lobe syndromes were; 1.Suspicious malignancy 2.Fixed bronchiectasis 3.Bronchostenosis 4.Intractability to medical treatment or recurrent atelectasis and obstructive pneumonia.
