    ABSTRACT: A 41-year-old male complaining of difficulty in swallowing was referred to our hospital. Chest computed tomography( CT) demonstrated 34×25×36 mm tumors in the subcarinal region. Gadolinium( Gd)-diethylenetriamine pentaacetic acid( DTPA) enhanced magnetic resonance imaging (MRI) showed the tumor with the target appearance sign, i.e., signal intensity of the mass was low on T1-weighted MRI, and the center of the mass was enhanced by Gd-DTPA. A neurogenic tumor was suspected on radiological findings. Resection of the tumor by video-assisted thoracoscopic surgery was performed. The tumor was found to originate from the left vagus nerve by operative findings and was diagnosed as schwannoma by pathological examination.

    ABSTRACT: A 61-year-old female who was diagnosed with right lung cancer had right lower lobectomy by videoassisted thoracic surgery in June 2010. At the 7th post operative day( 7POD), the patient complained of dyspnea and chest X-ray showed right pneumothorax which was successfully treated by closed drainage and pleurodesis. Since then repeated right pneumothorax appeared and the same procedures were chosen for treatment. In September 2010, just after the pleurodesis for the 3rd time event, she lost consciousness. Brain computed tomography (CT) demonstrated air density area in bilateral internal carotid arteries and right parietal lobe, establishing the diagnosis of air embolism which was successfully treated by hyperbaric oxygen treatment.

    ABSTRACT: We report a case of 68-year-old-man with pulmonary metastases from hepatocellular carcinoma (HCC). Following right hepatic lobectomy in January 2005, 4 pulmonary metastases in the right lung were detected by chest computed tomography (CT) in September 2007. As chemotherapy was not effective, surgical resection (right upper lobectomy, partial resection of middle and lower lobe ) was performed. Secondary metastases in the left lung was detected in March 2008, and stereotactic radiotherapy was performed considering the site of tumor location and poor pulmonary function. Two years after radiotherapy, the patient is alive without recurrence.

    ABSTRACT: Sodium alginate is the main ingredient of the seaweed, and its water solution has moderate viscosity. The areas of the pleural defect and around the suture line were covered with polyglycolic acid felt by using 5% sodium alginate water solution in 41 patients who underwent pulmonary resection from November 2006 to April 2007. 28 patients were lung cancer, 6 patients were pulmonary metastasis, and 7 patients were pneumothorax. The duration of the postoperative air leakage was 0.7 days on average. Neither side effect nor complication was observed. This method is cheap, safe, and effective for prevention for postoperative pulmonary fistula.

    ABSTRACT: Pneumothorax frequently requires drainage, and many thoracic surgeons continue to use the traditional rigid chest tubes. Traditional tube thoracostomy using a large-bore tube is an essential technique for thoracic surgeons, but it is associated with significant pain at the time of insertion and during continued drainage. We have found a new small-bore, flexible thoracostomy method using a modified central venous catheter that is simple, less painful, and safe.

    ABSTRACT: A 68-year-old male, pointed out of bilateral lung tumors, was hospitalized for the evaluation of multiple lung tumors. Chest computed tomography demonstrated 10 x 10 mm and 30 x 60 mm tumors in left lower lung and a 16 x 16 mm tumor in right lower lung. He was operated under the diagnosis of intracranial meningioma 26-years ago. For purpose of diagnosis, partial resections of left lower lung were performed, and then these tumors were diagnosed as pulmonary metastasis of intracranial meningioma. This is a very rare case of pulmonary metastasis of meningioma 26-years after craniotomy.

    ABSTRACT: A 76-year-old female was admitted to the hospital with dyspnea and hypertention. She had the giant thyroid tumor which had been awared but not treated for 40 years. On a computed tomography (CT) scan and magnetic resonance imaging (MRI), the tumor was 14 x 10 cm and the tracheal stenosis was completely intrathoracic, which was 5 x 7 mm. Tracheal incubation was performed safety by using percutaneous cardiopulmonary support. A subtotal thyroidectomy was performed by midsternotomy with cervical incision. The weight of the resected specimen was 340 g and the pathological diagnosis was follicular thyroid carcinoma. The postoperative course was uneventful and the patient suffered no hoarseness and dyspnea.

    ABSTRACT: A 78-year-old man underwent a left lower sleeve lobectomy and lymph node dissection for lung cancer. His postoperative course had been uneventful until postoperative day (POD) 3, but severe dyspnea occurred suddenly and the chest X-p showed infiltration shadow on POD 3. Streptococcus pneumonia antigen in the urine was elevated, suggesting pneumonia caused by Streptococcus pneumonia. The patient was treated with double dose of imipenem/cilastatin sodium and supported with a mechanical ventilator in an intensive care unit. Although the patient recovered from penicillin resistant Streptococcus pneumonia, he was suffered from Klebsiella sepsis and expired on the POD 26.

    ABSTRACT: A 52-year old female with anomalous systemic arterial supply to pulmonary sequestration was reported. The patient was admitted because of an abnormal lung shadow on chest X-ray film. Computed tomography (CT) showed an anomalous systemic arterial supply to pulmonary sequestration of the left lower lung without lung infection. Video-assisted thoracoscopic surgery for ligation of the anomalous systemic artery was performed. Postoperative course has been uneventful for 14 months after surgery. Blood supply increased to the left lower lung by 3-dimensional CT after surgery. The ligation of anomalous systemic arterial is enough for this disease.

    ABSTRACT: This study was done for the purpose of picking out the cases of poor prognosis from the peripherally located stage I adenocarcinoma of the lung. Between January 1989 and December 2004, 235 patients with peripherally located stage I adenocarcinoma of the lung were resected curatively in our hospital. Relation between the 5-year survival rate and lymphatic and/or blood vessel invasion (from now on ductal invasion) was examined in these cases. The 5-year survival rate was 99% in ly0v0 cases, 86% in ly0v1 cases, 85% in ly1v0 cases, 72% in ly1v1 cases, and 80% in ly2, 3 and/or v2, 3 (lyv 2-3) cases, respectively. Obviously the outcome of the cases without ductal invasion was good. The ratio of the cases without ductal invasion was 61% in stage IA, and 31% in stage IB. The 5-year survival rate was 99% in the cases without ductal invasion in stage IA, 100% in the cases without ductal invasion in stage IB, 90% in the cases with ductal invasion in stage IA, and 65% in the cases with ductal invasion in stage IB, respectively. And the 5-year survival rate without recurrence was 94% in the cases without ductal invasion in stage IA, 76% in the cases without ductal invasion in stage IB, 76% in the cases with ductal invasion in stage IA, and 54% in the cases with ductal invasion in stage IB, respectively. Ductal invasion is significant prognostic factor in stage I adenocarcinoma of the lung. Adjuvant chemotherapy is unnecessary for the case without ductal invasion in stage IA. But we think that adjuvant chemotherapy is necessary for the case with ductal invasion in stage IA and for the case in stage IB, because there is much recurrence.

    ABSTRACT: A 30-year-old female complaint of epigastralgia was diagnosed hepatic epitheloid hemangio endothelioma (EHE) by liver biopsy. The multiple nodules in bilateral lungs and liver were revealed on computed tomography (CT). The tumors of the left lung were resected under video-assisted thoracoscopic surgery. Pathologically these lesions were diagnosed as metastasis from EHE of the liver, and the patient was treated with interleukin-2 from hepatic artery for 12 months.

    ABSTRACT: Blunt tracheobronchial injuries are rare, but can be life-threatening. A precise preoperative diagnosis and a well-recognised plan of surgical treatment, which may be unique for each patient, are needed to restore the continuity of tracheobronchial tree in a one-stage intervention. We encountered a patient with complete tracheal transection and 15 cm tear in the posterior membranous trachea and right bronchus, and whose tracheal injury was difficult to repair using direct intubation of distal airway by bronchoscopy. We achieved a good result of one-stage repair using a percutaneous cardiopulmonary support (PCPS).

    ABSTRACT: A 63-year-old female, who had undergone a modified radical mastectomy for breast cancer at the age of 45, was suffered from trachyphonia due to left recurrent nerve paralysis at the age of 53. She presented left phrenic nerve paralysis and dysphagia at the age of 61. Computed tomography (CT) revealed mediastinal fibrosis, stenosis of esophagus and superior vena cava, and slight lymph nodes swelling. Video-assisted thoracoscopic mediastinal biopsy was performed and the mediastinal fibrosis was diagnosed as recurrence of breast cancer 17 years after the breast cancer operation. She underwent mediastinal radiation and chemotherapy for mediastinal recurrence and stenting for esophageal stenosis.

    ABSTRACT: Blunt tracheobronchial injuries are rare, but can be life-threatening. A precise preoperative diagnosis and well recognized plan of surgical treatment, which may be unique for each patient are needed to restore the continuity of tracheobronchial tree in a one-stage intervention. We encountered 2 patients with complete tracheal transection of neck and 1 patient with complete tracheal transection in mediastinum and 15 cm tear in the posterior membranous trachea, whose tracheal injury was difficult to repair using direct intubation of distal airway by bronchoscopy. We achieved a good result of repair using a percutaneous cardiopulmonary support system (PCPS).

    ABSTRACT: A 46-year-old female with benign metastasizing leiomyoma was reported. The patient had undergone a lobectomy of thyroid for adenomatous goiter at the age of 30, and a myomectomy for uterine myoma and a modified radical masmectomy for breast cancer at the age of 32. The chest X-ray on health screening revealed multiple nodules in the bilateral lung. Computed tomography (CT) revealed 6 nodules in the right side and 3 nodules in the left side of the lung. The tumors of the right lung were resected under thoracoscopic surgery. Pathologically these lesions were diagnosed as benign metastasizing leiomyoma. Left lung nodules have been followed-up.
