[Thoracoscopic Resection of Schwannoma Using Intraoperative Neurophysiological Monitoring: Report of a Case].

A 28-year-old right-handed woman had been diagnosed with a tumor of 30 mm in a diameter at the right first intercostal space adjacent to brachial nerve plexus. It was incidentally detected by medical checkup examination five years ago. Because the tumor enlarged to 36 mm in five years without any symptoms, thoracoscopic tumor resection was planned for diagnosis.

[Usefulness of Oxidization-regenerated Cellulose Sheets in Preventing Postoperative Adhesion Confirmed at Second Surgery for Lung Cancer].

The patient was a 42-year-old woman who had been found to have a mixed ground glass opacity in the lung on chest computed tomography, and had underwent right S6 segmentectomy. At surgery, the plain between the upper and lower lobe was covered with a regenerative oxidized cellulose membrane. Two years later, multiple small shadows appeared in the remaining right lower lobe and completion right lower lobectomy was performed by thoracoscopy due to the adhesion to the absence of adhesion.

[Intrapulmonary hematoma masquerading as metastatic carcinoma of lung cancer].

We herein report a case of intrapulmonary hematoma after lobectomy for lung cancer. A 51-year-old male underwent right upper lobectomy for lung cancer in a thoracoscopic procedure. Three months after the operation, chest computed tomography showed a 16-mm well-circumscribed nodule in the right lower lobe suggesting metastatic carcinoma for lung cancer.

[Malignant peripheral nerve sheath tumor causing hemothorax; report of a case].

We herein report a case of malignant peripheral nerve sheath tumor that caused a hemothorax. A 39-year-old male was found to have an abnormal shadow on a chest X-ray. Chest computed tomography showed a 60-mm tumor in the right posterior mediastinum.

Safe stapling technique for pulmonary vessels with the shortened introducers and curved tips in thoracoscopic surgery.

Endo GIA(™) curved tips with Tri-Stapler(™) is more useful for the approach for pulmonary vessels than conventional straight staplers. Unless adequate space is maintained below the vessels, there is a risk of causing damage to the back of vessels with the curved tip without optional introducers. The recommended method involves passing silk thread through the back of the pulmonary vessels and ligating the thread to the introducer.

[Pulmonary mucosal associated lymphoid tissue( MALT) lymphoma with 7-year natural history; computed tomography( CT) scan findings and pathological correlations].

A 58-year-old man was found to have an abnormal shadow on chest computed tomography (CT). The size and density of the nodule increased gradually over 7 years. Partial lung resection was performed by a thoracoscopic procedure.

[Hyperbaric oxygen therapy for air embolism complicating computed tomography (CT)-guided needle marking of the lung].

Preoperative computed tomography( CT)-guided marking with a short hook wire for small sized lung tumors has become popular along with the spread of thoracoscopic surgery. Systemic arterial air embolism is a very rare but potentially fatal complication. The patient was a 79-year-old man who was found to have a mixed ground glass opacity shadow on chest CT.

A thymic cyst in the middle mediastinum: report of a case.

Background: Thymic cysts are usually located in the neck or anterior mediastinal compartment. Thymic cysts arising in the middle mediastinum are extremely rare, with only 2 previously reported cases. We herein describe the third case of a thymic cyst in the middle mediastinum.

A case of sclerosing hemangioma forming a pedunculated mass.

We report our experience with an unusual case of sclerosing hemangioma (SH) that formed a pedunculated mass protruding into the thoracic cavity. A pulmonary tumor was found in a 60-year-old female during the medical examination. Computed tomography showed a 19 × 17-mm nodule with a clear border and smooth margin contiguous with the diaphragm in the right S8 segment.
