Congenital Cystic Lung Disease is a spectrum of closed related anomalies that arise during an early stage of embryonic lung bud maturation-namely bronchogenic cyst, congenital lobar emphysema, pulmonary sequestration and congenital cystic adenomatoid malformation. And they show similar surgical strategies. So they are called as the term bronchopulmonary-foregut malformations, firstly proposed by Gerle[1968]. From Aug. 1979 to Aug 1989, 47 patients were operated upon on Dept. of Thoracic & Cardiovascular Surgery at the CUMC. There were 21 females and 26 males ranging in age from age of 21 day to age of 56 year [15 cases under 15 years old]. 30 patients had bronchogenic cysts - 23 of intrapulmonary type, 7 of mediastinal type in location. Affected lobes and locations were as follows: 11 in upper lobe, 3 in middle lobe, 11 in lower lobe and anterosuperior, middle, and posterior mediastinal type were 3, 2, 2 respectively. There were 9 pulmonary sequestrations[all intralobar type] with the distribution of 5 in right lower lobe and 4 in left lower lobe. And associated anomalies were presented with arterial supply originating from thoracic aorta[8 cases], abdominal aorta[1 case] and with venous drainage into azygos vein[1 case]. They all were operated upon lower lobectomy [8 case], pneumonectomy[1 case] in case of pulmonary hypoplasia Congenital lobar emphysema and congenital cystic adenomatoid malformation had 4 cases respectively. Their affected lobes were as follows: the former were 3 in upper lobes, 1 in middle lobe and the latter were 3 in upper lobe, 1 in lower lobe. They were treated with lobectomy and segmentectomy. Diagnosis was aided by chest X - ray, bronchography, aortography, DSA and CT scan, They all were confirmed by pathologic exams. There were no hospital death but few minor morbidities such as, atelectasis-pneumonia[2], wound infection[2], prolonged chest tube placement[2]. We experienced surgical treatments of 47 cases for 10 years and reported them with literature review.

Objective: To explore the feasibility of pulmonary lobectomy combined with pulmonary arterioplasty by complete video-assisted thoracic surgery (VATS) in patients with lung cancer, and summarize its surgical methods. Materials and Methods: Twenty-one patients with lung cancer in Beijing Chest Hospital Affiliated to Capital Medical University from Feb., 2010 to Jun., 2013 were selected, males and females accounting for 15 and 6 cases, respectively. Ten underwent right upper lobectomy, 5 right lower lobectomy, 4 left upper lobectomy (in which left upper sleeve lobectomy was conducted for 2) and 2 left lower lobectomy. At the same time, local resection of pulmonary arterioplasty was performed for 12 patients, and sleeve resection of pulmonary arterioplasty for 9. Results: Twenty-one patients recovered well after surgery. Thoracic drainage tube was maintained for 3-8 days, with an average of 4.9 days, and hospital stays were 8-15 days, with an average of 11 days. There were no deaths in the perioperative period, and the complications like pulmonary embolism, bronchopleural fistula, chest infection and pulmonary atelectasis did not occur after surgery. Conclusions: Performance of pulmonary lobectomy and pulmonary arterioplasty together by complete VATS is a safe and effective surgical method, which can expand the indications of patients with lung cancer undergoing thoracoscopic pulmonary lobectomy, and make more patients profit from such minimally invasive treatment.

Objective : This study was conducted to assess the surgical results of one-stage posterior minimal laminectomy and video-assisted thoracoscopic surgery (VATS) for the treatment of thoracic dumbbell tumor and to describe its precise technique. In addition, we investigated the technique's usefulness and limitations. Methods : Seven cases of thoracic dumbbell tumor (two men and five women, mean age, 43 years) were analyzed retrospectively. Pathological findings included schwannoma in four patients, neurofibroma in two patients, and hemangioma in one patient. The location of tumors varied from T2/3 to T12/L1. Dumbbell tumors were resected by one-stage operation using posterior laminectomy followed by VATS without instrumentation. Clinical data were reviewed. Results : The mean follow-up period was 25 months (range, 3-58 months), and the operative time ranged from 255 to 385 min (mean, 331 min), with estimated blood loss ranging from 110 to 930 mL (mean, 348 mL). The tumor was completely resected without instrumentation and postoperative instability in all cases. Postoperative complications included atelectasis and facial anhydrosis in one case each. Conclusion : One-stage posterior minimal laminectomy and VATS may be a safe and less invasive technique for removal of thoracic dumbbell tumor without instability. This method has the advantage of early ambulation and rapid recovery because it reduces blood loss and postoperative pain.

The experimental study for extracorporeal preservation of the heart-lung preparation by autoperfusion system was performed in 10 dogs. Under intravenous Pentothal endotracheal anesthesia bilateral thoracotomies were performed. A 24F cannula connected to a plastic reservoir bag located 100 cm above the level of the heart was introduced into the aortic arch. Left subclavian, innominate artery, and descending aorta were ligated and divided. Both vena cavae were ligated and divided after the bag was half filled with blood. A 24F catheter inserted into right atrium and connected to the plastic bag in order to keep constant the preload. The thoracic trachea was intubated and the lungs were ventilated. The heart-lung preparations were removed en bloc and floated in a $34^{\circ}C$ bath of Hartmann solution. The preparations were observed for from 2 hours to 8 hours, with the average of 5.2 hours. Hemodynamic and hematologic variables were measured during preharvest and autoperfusion. The pH revealed severe respiratory alkalosis due to very low $PaCO_2$ during autoperfusion ; $PaO_2$ remained constant for 130-140 mmHg; $A-aDO_2$ increased markedly. The static inspiratory pressure [SIP] at late autoperfusion [6hr] increased significantly as compared with at early autoperfusion [2hr]. There was no difference between white blood cell counts from right atrium and those of left atrium. Heart rates remained constant for 110-120/min; cardiac outputs maintained to approximately 0.6L/min; mean aortic pressures, 75 mmHg; mean pulmonary arterial pressures, 15-18 mmHg; mean right atrial pressures, 9-13 mmHg; mean left atrial pressures, 12 mmHg lower than those of right atrium. Serum Na maintained with normal range during autoperfusion; K increased significantly; Ca decreased progressively. Hemoglobin and hematocrit decreased significantly during autoperfusion. The study demonstrated that stable hemodynamics could be maintained throughout the experiment and the preparation of the lung seemed to be inadequate, especially after 3-4 hours, such as high $A-aDO_2$, increased SIP, and scattered atelectasis and edema in their gross appearances.

Over the past few years, video-assisted thoracic surgery [VATS] has been used increasingly for intrathoracic pathologic problems as a less invasive operative techniques. Today it is viewed as a sparing and safe alternative to thoracotomy for a wide spectrum of indications. Using video-assisted operative thoracoscopy, we performed consecutive 150 operations on 148 patients during the initial 2 years of our experience from July 1992 with the following indications: pneumothorax [n=53], hyperhidrosis [n=29], mediastinal mass [n=23], pleural disease [n=13], diffuse parenchymal or interstitial lung disease [n=12], benign pulmonary nodule [n=7], metastatic lung mass [n=3], primary lung cancer [n=3], bronchiectasis [n=2], malignant pericardial effusion [n=2], endobronchial tuberculosis [n=1], esophageal achalasia [n=1], and pulmonary parenchymal foreign body [n=1]. There were no death, and overall complicaton rate was 24.0%[n=36]. The most prevalent complication was persistent air leakage [longer than 5 days] in 14 cases [9.3%]. Persistent pleural effusion [longer than 5 days] occurred in 6 cases [4.0%]. Six patients were converted to an open thoracotomy because of inability to control the operative bleeding [n=3], failed adhesiolysis in bronchiectasis [n=2], and radical excision of an lung cancer [n=1]. Pneumothorax recurred in 3 cases[2.0%]. Other complications were Horner`s syndrome, diaphragm tears, temporary phrenic nerve palsy, hoarseness, subsegmental atelectasis, transient respiratory difficulty, and esophageal mucosal tear. The advantages of this minimally traumatizing operative technique lie in improved visualization, decreased pain, shortened hospital stay, and less postoperative morbidity. The indications of VATS has been extended increasingly to intrathoracic pathologies, but its role in the managements of primary lung cancer and esophageal disease remains to be defined.

We performed serial pulmonary function test and arterial blood gas analysis at preoperative period and postoperative 1st week in 337 patients who underwent pulmonary resection from May 1988 to April 1992 at Dept. of Thoracic and Cardiovascular Surgery, Seoul adventist hospital. Follow-up study for PFT and ABGA were possible in 30 % of the patients at postoperative 3rd or 4th month. In patient who underwent pneumonectomy, VC was decreased from 57.7% to 46.1%, FVC was decreased from 53.5 % to 41.2 % and MBC also decreased from 68.1% to 49.6 % at postoperative 1st week. But ABGA revealed that POa-, was increased from 87.2 mmHg to 92.7 mmHg, and PCO2 was decreased from 43.2 mmHg to 35.9 mmHg at postoperative 1st week. In patients who underwent lobectomy, VC was decreased from 78.1% to 68.30 %, FVC was decreased from 72.5% to 55.3% and MBC was decreased from 73.5% to 68% at postoperative 1st week.But, ABGA revealed that PO2 was increased from 95.2 mmHg to 97.9 mmHg and PCO2 was decreased from 42.3 mmHg to 39.0 mmHg at postoperative 1st week. The pulmonary function recovered at postoperative 3rd or 4th month and its ratio to preoperative value was 90% in lobectomy cases, but in pneumonectomy cases VC and MBC were recovered 20% and 15 % above the preoperative values. We concluded that resection of atelectasis, destructed lung, open negative and open positive cavity in the pulmonary tuberculosis were beni~t to improve ventilation-perfusion ratio,and pulmonary function was recovered nearly to preoperative level at postoperative 3rd or 4th month.
