ABSTRACT

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. As no improvements were seen after 4 months of antibiotic administration, and accumulation was observed at the same site on positron emission tomography (PET), the patient was diagnosed with lung cancer and underwent surgery. Following segmental resection, the patient was found to have pulmonary actinomycosis. It is necessary to consider pulmonary actinomycosis in patients with lung tumors.

ABSTRACT

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. Regrettably, it ruptured into a pyopneumothorax. The BPF was closed primarily and covered with intercostal muscle, but the procedure was not effective. The pyopneumothorax led to the development of chronic empyema with BPF. The patient was admitted to our hospital for treatment and the BPF was managed with a Dumon stent and endobronchial Watanabe spigot (EWS) but failed to heal. Therefore, open drainage was chosen as a 1st stage treatment. After healing the infected space, closure of the BPF and a bronchial embolization by EWS was performed with a closeire of space by pediculed omentum and muscle flap and with a thoracoplasty as a 2nd stage treatment. The postoperative course was uneventful, and the patient was discharged on post-operative day 51.

ABSTRACT

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). The levels of postoperative air leakage and postoperative complications were examined among the two groups retrospectively. The histological findings of the cut surface of the segmentectomy by electrocautery and harmonic scalpel were also examined. RESULTS: Hemostasis and air leakage both were well controlled during the operation, and the postoperative drainage period was short. No major postoperative complications occurred, and all patients began walking in the early postoperative days. However, 1 to 3 postoperative months after discharge, 8 patients showed late onset of a pulmonary fistula, 3 of the 17 (18%) in the EC group and 5 of the 11 (45%) in the HS group. The histological findings of the cut surface of the segmentectomy showed that most of the layer of coagulation necrosis by the harmonic scalpel measured 2 mm thick, and it was denser than that cut from electrocautery. The lumen of the bronchus markedly decreased in size, but it remained, as it also did under the effects of electrocautery. CONCLUSIONS: In the months following the operation, the incidence of the late onset of a pulmonary fistula was higher when the harmonic scalpel was used. It was believed that the small bronchial stump could not tolerate the airway pressure because the thick coagulation necrosis delayed healing of the postoperative wound. It was necessary to ligate the stump of a small bronchus, even though the stump had been temporally closed by coagulation necrosis with the electrocautery or harmonic scalpel during the operation.

ABSTRACT

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. Despite a small air leakage, which became evident on day 4 of drainage, shrinkage of the bulla was achieved, and elective bullectomy was performed after continuous drainage for 21 days. Thus, percutaneous drainage was effective in controlling the infection and minimizing the invasiveness of surgery.

ABSTRACT

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. However, the existence of a primary tumor was not confirmed using these modalities. Therefore, FDG-PET (positron emission tomography with fluorodeoxyglucose) was performed and demonstrated accumulation corresponding to the anterior mediastinum, although the exact location of the tumor was unclear by FDG-PET alone. Therefore, FDG-PET/CT image fusion was performed and resulted in the detection of a tracheal carcinoma on the outside of the right side of the tracheal wall. The patient then underwent tracheal sleeve resection including the tumor and tracheoplasty accompanied with wrapping using the flap of the thymus right lobe. To the best of our knowledge, this is the first reported case of tracheal carcinoma detected by FDG-PET/CT image fusion with consequent radical resection.
