We treated a patient with postlobectomy persistent alveolar fistula using a tissue expander, which is a prosthesis widely used in plastic surgery. The patient had thoracic empyema develop after right bilobectomy for lung cancer, and consequently underwent drainage of empyema followed by muscle flap closure for alveolar fistula. A residual space remained,(More)
A 68 year-old man was referred and admitted to our hospital because of hoarseness due to recurrent nerve palsy and an anterior mediastinal tumor detected on chest CT. Chest CT showed a low-density tumor surrounding the aorta and branching arteries. Chest MRI revealed a low-intensity tumor in both T1- and T2-weighted images. The tumor was adjacent to the(More)
The prognosis of patients with differentiated thyroid cancer is relatively fair, with a 10-year survival rate above 80%. One of the important prognostic factors is cancer invasion to the airway. For the last 25 years we have been performing combined resection of the trachea and larynx and have reported a relatively good 10-year survival (67.7%) and improved(More)
Thymidylate synthase (TS) is an enzyme that catalyzes an important DNA biosynthesis process. The gene expression of TS has not been reported in non-small-cell lung cancer (NSCLC) patients. To clarify the correlation between TS mRNA levels and clinicopathological features of NSCLC, we examined 70 Stage I and II NSCLC patients for intra-tumoral expression of(More)
Superior vena cava (SVC) and inferior vena cava (IVC) pressures were measured serially during laparoscopic cholecystectomy in which the intra-abdominal pressure was maintained at 12 mmHg. The influences of alteration of position from 15 degrees head-down to 15 degrees head-up and of the operative procedure of holding the gallbladder up to the right(More)
The purpose of this report is to discuss the appropriate choice of procedures for video-assisted resection of thymoma according to factors such as the presence of myasthenia gravis or location of the tumor. We evaluated the short-term results of thoracoscopic surgery for 30 consecutive cases of noninvasive thymoma. Unilateral thoracoscopic partial (or(More)
We present herein the case of a 73-year-old woman with symptomatic liver cysts and cholelithiasis for whom successful deroofing of the liver cysts and cholecystectomy were performed via laparoscopy. Histopathological diagnosis of the resected cyst wall and direct observation of the inner surface of the remaining cyst wall confirmed that they were benign(More)
OBJECTIVE To evaluate the impact on patient survival of video-assisted thoracoscopic surgery (VATS) thymectomy for the treatment of early-stage thymoma, by comparing the intermediate-term oncologic outcomes with outcomes after open thymectomy. METHODS Eighty-two patients who underwent complete resection of a Masaoka stage I or II thymoma between November(More)
A 62-year old female patient in whom paradoxical right atrial to left atrial shunt flow through the foramen ovale was detected by transesophageal echocardiography during pneumoperitoneum for laparoscopic cholecystectomy was reported. This patient had a history of mitral valve replacement with residual tricuspid valve regurgitation. It was considered that(More)
Pseudoaneurysm of the pulmonary artery (PA) induced by Swan-Ganz catheter injury is an important complication with high mortality. We report a case of PA pseudoaneurysm treated by PA repair. A 52-year-old woman developing infiltrate in the right lung field in chest radiography after a second mitral valve replacement was diagnosed with PA pseudoaneurysm(More)
