Management of thoracic empyema with broncho-pulmonary fistula in combination with negative-pressure wound therapy.

OBJECTIVE: Intrathoracic negative-pressure wound therapy (NPWT) has been introduced as a novel therapeutic device for the management of empyema. NPWT is expected to reduce the empyema cavity more rapidly than standard treatments; however, no objective analysis of the function of NPWT has yet been conducted. The study objective was to evaluate the efficacy of NPWT in the management of thoracic empyema. METHODS: Ten patients with stage II or III thoracic empyema treated with NPWT were retrospectively analyzed. The volume of the empyema cavity was measured, and the volume change after the administration of NPWT was calculated. A comparison with the institutional historical controls was also performed. RESULTS: The patients had initially undergone fenestration of the chest wall for empyema, and eight had bronchopleural fistula and required procedures to close the fistula. The mean duration of NPWT was 71.1 days (4-190 days). The mean volume of the empyema cavity decreased from 230.2 ml (42.8-788.4 ml) to 78.5 ml (5.2-185.3 ml) by applying NPWT (P = 0.02), and the mean % decrease was 58.7% (0-87.9%). Ultimately, the empyema cavity was able to be cleaned in nine, including seven who were cured by subsequent thoracoplasty and two who were cured without thoracoplasty. The current study group had a tendency toward an early cure with less chest wall destruction, a less hospital stay after open window thoracotomy compared to historical control. CONCLUSIONS: NPWT enables the effective volume reduction and cleaning of the empyema cavity and achieves an early cure and reduced destruction of the chest wall.

A surgical case of synchronous solitary splenic metastasis from lung squamous cell carcinoma: report of a case and review of the literature.

Solitary splenic metastasis is an extremely rare event. We herein report a surgical case of a solitary splenic metastasis from lung cancer. A 78-year-old man presented with abdominal pain. Abdominal computed tomography (CT) showed splenic rupture. Coil embolization to the splenic artery was performed, and the patient's condition improved. Chest CT showed a 5-cm lung mass in the right upper lobe, suggesting lung cancer with splenic metastasis. Transbronchial aspiration cytology showed squamous cell carcinoma of the lung. We diagnosed the patient with lung cancer (cT2bN0M1b [spleen only] stage IVA) and performed splenectomy and right upper lobectomy separately. Both lesions were squamous cell carcinoma and positive for p40. Thus, primary lung squamous cell carcinoma and solitary splenic metastasis were diagnosed. The patient was still alive without recurrence 15 months postoperatively. We herein report a rare case of lung squamous cell carcinoma with solitary splenic metastasis and review the literature.

A case of primary pulmonary leiomyosarcoma completely resected after neoadjuvant chemotherapy.

BACKGROUND: Primary pulmonary leiomyosarcoma is a rare malignant tumor. We herein report a case of primary pulmonary leiomyosarcoma that was completely resected by surgery after neoadjuvant chemotherapy. CASE PRESENTATION: A 60-year-old man presented with cough. Chest computed tomography showed an 11-cm mass in the right upper lobe of the lung that had invaded the superior vena cava. Endobronchial ultrasound-guided transbronchial needle aspiration revealed leiomyosarcoma of the lung. We considered complete resection of the tumor to be very difficult because of the tumor invasion into the right atrium inflow of the superior vena cava, so we performed chemotherapy using doxorubicin for five cycles. After chemotherapy, the tumor size decreased to 5.6 cm, and we performed right upper lobectomy with combined resection of the superior vena cava. The tumor was completely resected by surgery. The patient is alive without recurrence 17 months postoperatively. CONCLUSIONS: We encountered a case of primary pulmonary leiomyosarcoma that was successfully treated by surgery after neoadjuvant chemotherapy. Doxorubicin monotherapy was effective in this case. Surgery combined with neoadjuvant chemotherapy should be considered for such cases, as a long-term survival can be achieved by complete resection of primary pulmonary leiomyosarcoma.

A strategy for pulmonary resection after contralateral diaphragm plication: a surgical case report.

BACKGROUND: Pulmonary carcinoma patients with low pulmonary function cannot be treated surgically because of the high risk of complications. Diaphragmatic eventration is a disease characterized by diaphragmatic paralysis and dyspnea. Here, we report a surgical case of multiple pulmonary carcinomas with contralateral diaphragmatic eventration. CASE PRESENTATION: The patient was a 75-year-old woman with multiple metachronous right lung carcinomas complicated by left diaphragmatic eventration. When she was 70 years old, a right upper lobectomy and right S6b wedge resection were performed for double lung carcinomas. Five years later, two new lung tumors in her right lower lobe and left diaphragmatic eventration were identified, but resection was thought to be impossible because of her low pulmonary function. We performed video-assisted thoracoscopic surgery (VATS) plication with carbon dioxide (CO2) insufflation for the left diaphragmatic eventration, and her pulmonary function improved. Subsequently, we performed a right S6 wedge resection and right S9 segmentectomy for the double lung tumors with no complications. The tumors were diagnosed as double primary carcinomas. CONCLUSIONS: Our case presented with low pulmonary function and right multiple lung carcinomas with left diaphragmatic eventration. VATS plication for the left diaphragmatic eventration achieved improvement in her pulmonary function, and right pulmonary resection for the lung carcinomas was performed. VATS plication can expand the choice of treatments in such cases.
