The goal of surgical treatment for gastrointestinal stromal tumor (GIST) is the complete resection of the tumor. A 62-year-old male had a clearly distinguishable mass having a smooth surface at the right side of the lower esophagus by computed tomography. Thoracoscopic resection of the tumor was performed. Immunohistochemical analysis showed that the tumor(More)
This report describes a 3-dimensional (3-D) video-assisted thoracoscopic lung resection guided by a 3-D video navigation system having a patient-specific 3-D reconstructed pulmonary model obtained by preoperative simulation. A 78-year-old man was found to have a small solitary pulmonary nodule in the left upper lobe in chest computed tomography. By a(More)
INTRODUCTION The number of renal transplantations performed for patients with chronic kidney disease has increased in Japan, but little is known about the outcomes in those who subsequently undergo video-assisted thoracoscopic surgery (VATS). We therefore investigated the outcomes of consecutive patients requiring VATS after renal transplantation at our(More)
Muscle flap transposition is one of the surgical treatment options for empyema with alveolarpleural fistula (APF) or bronchopleural fistula (BPF). This surgical procedure is invasive because it is typically performed by standard thoracotomy. We performed video-assisted thoracoscopic surgery (VATS) debridement, decortication, and obliteration of an empyema(More)
A 26-year-old man underwent arterial switch surgery for transposition of the great arteries in infancy. During a routine evaluation, a nodule was detected in the left lower lobe on chest computed tomography. The tumor had enlarged at follow-up and he underwent surgical resection. Because of past cardiac surgery, the pericardium was defective; therefore, the(More)
BACKGROUND This study investigated the efficacy of binocular stereo-navigation during three-dimensional (3-D) thoracoscopic sublobar resection (TSLR). METHODS From July 2001, the authors' department began to use a virtual 3-D pulmonary model on a personal computer (PC) for preoperative simulation before thoracoscopic lung resection and for intraoperative(More)
We reported a case of bilateral endobronchial metastasis in postoperative synchronous adenocarcinoma. Twenty months ago, a 63-year-old man underwent combined operation. Biopsy was performed, histological diagnosis of pulmonary adenocarcinoma. When surgery is not indicated because the patient has decreased pulmonary function and contralateral metastatic(More)
