[Completion pneumonectomy after 4 times of resections for metastatic lung tumors from rectal carcinoma].

We report a case of completion pneumonectomy after 4 times of metastasectomy for metastatic lung tumors from rectal carcinoma. A 63-year-old man underwent Miles' operation for advanced rectal carcinoma. Forty-seven months after the operation, bilateral metastasis was appeared, and bilateral metastasectomy was performed. After the resection, 3 times of metastasectomy were performed during 40 months. Follow-up X-ray and computed tomography (CT) showed abnormal shadow in his left hilum of lung. Completion pneumonectomy with mediastinal lymph node sampling was performed. He is still alive without recurrence 4 years after first thoracotomy. Repeated pulmonary resection can lead to good outcome for selective patients with metastatic colorectal carcinoma, and repeated surgery can be useful for pulmonary recurrences after thoracotomy.

[Perioperative targeting brachytherapy for lung cancer invading the chest wall].

We evaluated the efficacy of perioperative targeting brachytherapy for lung cancer invading the chest wall. Between 1998 and 2003, 7 patients underwent perioperative targeting brachytherapy for lung cancer invading the chest wall. There were 5 male and 2 female patients. The mean age was 63.3 years, with a range of 45 to 77 years. All patients underwent complete resection including the chest wall combined resection. During the operation, plastic afterloading catheters fixed on the Vicryl mesh at interval of 1 cm were placed on the site of chest wall resection. From the third to sixth day after the operation, 15 to 32 Gy of radiation was delivered over 3 or 4 days using a high dose rate remote afterloading system. The area targeted for brachytherapy was determined by a computed tomography (CT) scanner translator with a computer program for radiation planning. The median postoperative hospital stay was 35 days. Local recurrences were observed in 2 patients, but there was no evidence of recurrence in the margin of the resected chest wall. We believe that this short period of treatment and the low side effects enhances the quality of the patients. Prevention of local recurrence was achieved in short term follow-up.

[Catamenial pneumothorax in a young patient diagnosed by thoracoscopic surgery; report of a case].

A 16-year-old woman presented with chest pain on 2 days before the onset of menstruation and was referred to our hospital because of a pneumothorax. She was diagnosed as spontaneous penumothorax and surgical treatment was performed. Thoracoscopy revealed the presence of multiple blueberry spots near central tendon of the diaphragm and little pleural effusion. No other abnormal lesions were found in the left pleural cavity and left lung. Thoracoscopic biopsy and coagulation of the lesions were successfully performed. Histological findings of biopsied specimen did not contradict as an endometoriosis and catamenial pneumothorax was diagnosed. CA 125 level of the pleural effusion had increased to 99.2 U/ml. Because she was young, she did not receive a systemic hormonal therapy.

Bronchial sleeve resection with complete preservation of the lung for carcinoma.

Conservative sleeve resection with complete preservation of the lung parenchyma is very rarely applicable for the treatment of bronchial carcinomas. We used this surgical procedure in four patients with bronchial carcinoma in various sites of the central airway, and we obtained successful results. The pathological types were two squamous cell carcinomas and two low-grade malignant tumors (mucoepidermoid carcinoma and adenoid cystic carcinoma). If patients are properly selected, this operative procedure appears to be a safe and radical therapeutic option for the treatment of bronchial neoplasms arising from major bronchi.
