[Surgery for pulmonary actinomycosis that was difficult to differentiate from lung cancer; report of a case].

We herein report a case of pulmonary actinomycosis that was difficult to differentiate from lung cancer. The patient was a 53-year-old man who visited our hospital with a chief complaint of bloody sputum. Computed tomography (CT) showed a tumor in the anterior basal segment (S8) of the left lower lobe that contained a low density area, and because elevated C-reactive protein (CRP) was also observed, the patient was diagnosed with a lung abscess.

[Experience of successful treatment for a case of intractable chronic empyema with a bronchopleural fistula].

We report an experience of successful treatment for a case of intractable chronic empyema complicated by bronchopleural fistula (BPF). A 75-year-old woman who had severe diabetes mellitus complained of general fatigue and anorexia. A lung abscess in the right upper lobe was diagnosed and treated with antibiotics.

Late onset postoperative pulmonary fistula following a pulmonary segmentectomy using electrocautery or a harmonic scalpel.

Purpose: The purpose of this study is to retrospectively examine the postoperative pulmonary fistula as a complication after the use of either electrocautery or a harmonic scalpel without stapling devices.

Patients And Methods: The subjects of this study consisted of 28 patients who received a segmentectomy for a pulmonary malignant tumor, 25 cases of lung cancer and 3 of metastatic lung tumor. The electrocautery was used in 17 patients (EC group) and the harmonic scalpel in 11 (HS group).

Infected giant bulla treated by percutaneous drainage followed later by resection: report of a case.

A 55-year-old man was hospitalized for treatment of a giant, fluid-filled bulla in the upper lobe of the right lung. The infection was resistant to antibiotics, and the resulting drug-induced liver dysfunction prohibited us from performing emergency lobectomy. Percutaneous drainage of the bulla was done initially, using a 28-Fr chest tube, after which the symptoms of infection improved rapidly.

Occult cancer detected by positron emission tomography/computed tomography image fusion.

A 60-year-old male in a high-risk group for lung cancer, who also had positive sputum cytology, underwent examination by chest plain radiography, chest computed tomography (CT) and bronchofiberscopy. However, initially no abnormal findings were detected with these diagnostic modalities. Furthermore, thin-section spiral chest CT disclosed only a slight thickness of the right side of the tracheal wall, while consequent re-examination by bronchofiberscopy revealed only a light ulcerative lesion in the same area.
