[Synchronous Multicentric Thymoma].

A 76-year-old man was referred to our hospital because of an abnormal shadow on chest X-ray. His physical exams and laboratory data were not notable. Chest computed tomography (CT) showed 2 nodular lesions with clear margin in anterior mediastinum.

Video-assisted thoracoscopic surgery for lung cancer in patients on hemodialysis.

Purpose: Surgical treatment of lung cancer in patients receiving hemodialysis carries a high risk because of poor cardiac function and a fragile electrolyte balance. Because the number of patients receiving hemodialysis has increased, the proportion of such patients with lung cancer is expected to rise. However, few studies have examined the results of surgery for lung cancer in hemodialysis patients, especially by video-assisted thoracoscopic surgery (VATS).

Surgical results of video-assisted thoracic surgery and risk factors for prolonged hospitalization for secondary pneumothorax in elderly patients.

Background: The treatment of secondary pneumothorax in elderly patients is difficult because of underlying diffuse lung injury and complex medical comorbidities. Such patients still have high morbidity rates, resulting in longer periods of hospitalization.

Methods: To examine the results of video-assisted thoracic surgery for elderly patients (aged 70 years or over) with secondary pneumothorax and investigate the risk factors for hospital stay longer than 7 days, we retrospectively analyzed the results obtained in such patients at our institution.

Tracheal stenosis after metal stent insertion treated successfully with a T-tube.

Tracheal stenosis after intubation is a fairly common complication, and treatment of such cases can be difficult. A 52-year-old woman was admitted to our hospital because of severe dyspnea. Seven years previously, she had suffered tracheal stenosis after tracheal intubation and had undergone tracheal resection and placement of a self-expandable metal stent.
