Egyre gyakoribbá váló megbetegedés: pulmonalis dirofilariasis.

Due to the climate change zoonoses, dirofilariasis in particular is spreading. Hence, it is likely that we will encounter with this problem more frequently in the future Our intention with this case presentation is to draw attention to the increasing number of nematodes that cause differential diagnostic problems. The patient underwent surgery with suspicion of pulmonary malignancy suggested by a peripheral rounded opacity in imaging, but histological examination revealed dirofilariasis.

[Long-term survival after lung-sparing central bronchoplastic procedures [CBPs] for malignant tumors]. / Hosszú túléléssel járó malignus tumor miatti tüdomegtartó centrális fohörgoplasztikáink.

BACKGROUND: Bronchial malignancies are leading tumour-related cause of death. Prolonged survival can only be expected after radical resections. Central bronchoplastic procedures, which save the whole lung parenchyma, however, may play a role. AIM: These bronchoplastic procedures can be good alternatives for pulmonectomies. The value of these operations can be evaluated by postoperative mortality complication, and the survival rate. MATERIAL AND METHODS: In the period of 1985-2012 we operated 7130 bronchial carcinomas. Of these, 7 cases of 80 central broncoplastics we preserved the whole lung (in one case as an alternative for inoperability, in 6 patients as an option instead of pulmonectomy). The indications were carcinoid in four cases, epidermoid carcinoma, mucoepidermoid carcinoma and main carina SCLC after induction chemo-radiotherapy. The average age of the 4 male and of the 3 female patients were 28.5 (14-58) years. In 5 cases the right main bronchus, while in one case the left main bronchus was resected and the bronchial tree was reconstructed. In one case (SCLC patient) we made a complete carina resection and end-to-end anastomosis between the trachea and the rebuilt neocarina to preserve both lungs. The anastomosis was made with 3-4/0 PDS interrupted sutures above a sterile tube (6 cases) and in one case due to a jet catheter which were positioned through the operation field into the distal part of the main healthy bronchus. RESULTS: There was no operative mortality nor bronchopleural fistula. In the early postoperative period we applied repeated bronchoscopic suctions. In the patient with carina SCLC anastomosis stenosis developed. The main bronchi were temporarily stented. This patient is fit 174 months after the intervention, the Karnofsky index mesures to 90%. Other 5 patients are alive without any consequences of recurrence nor metastasis. The patient with epidermoid carcinoma died 83 months later because of distant metastases of a SCLC, originating from the contralateral lung. The mean survival is 118 (7-233) months. CONCLUSION: In case of some properly selected localised mainstem bronchial malignancies, such as young age and low grade malignancy, radical surgical interventions can be performed with long term survival preserving the whole lung due to special CBPs. Some such successful series and case reports (under 200 cases) can be found in the literature but the long-term survival data was not demonstrated in most publications. In Hungary there has not been any publications yet on such a successful series with long term survival. These results are remarkable within international standards.

[Pulmonary metastasectomy after pneumonectomy]. / Pneumonectomiát követoen végzett pulmonalis metastasectomiák.

UNLABELLED: INTRODUCTION, OBJECTIVES: Authors of two thoracic surgical departments from the above named hospitals discuss their practices of pulmonary metastasectomy after pneumonectomy for malignant disease. MATERIAL AND METHODS: Six patients were operated after pneumonectomy for metastatic spread in the residual lung. The average age of the three male and three female patients was 52.5 years. The applied preoperative diagnostical methods were the following: chest-x-ray, CT scan, MRI, PET-CT scan, perfusion lung scintigraphy, bronchological examinations, functional respiratory tests, ECG, cardiac echo, arterial blood gases (ABGs) and other laboratory analyses. Patient selection for operation was based on strict oncological and cardiorespiratory criteria. Finally, the authors describe the applied operative technique; atypical mechanical resection with stapler. RESULTS: Mean length of postoperative intensive care was between 3 to 7 days, while that of hospitalization altogether was 13 to 18 days (average 15.2 days). Ventilation needed for one patient for 5 days approximately. Two of the six patients' survival was 18 and 25 months after pulmonary metastasectomy. Four patients are still alive, their average postoperative survival is 33.5 months. They are followed up regularly and their quality of life is satisfactory. CONCLUSIONS: The key factors that determine the successful outcome of metastasectomies are careful and personalized evaluation of the patients, their condition and fitness for thoracotomy, stabile cardiopulmonary functions and the capacity of the residual lung. Multidisciplinary teamwork involving anaesthetists and intensive care specialists along with surgeons using the quick atypical resection technique are the key elements to improved survival of these patients.

[Thymic neuroendocrine tumor: three cases in our practice]. / A thymus neuroendokrin daganata: három esetünk ismertetése.

Authors present 3 cases of the thymic neuroendocrine tumor. They describe the diagnosis, the TNM classification, histology, therapy, and prognosis of the disease. In their opinion the TNM and histology classification have adequate prognostic value.
