Jornal Brasileiro de Pneumologia , 2008, DOI: 10.1590/S1806-37132008000600015
Abstract: we present a protocol to test a new surgical procedure for the treatment of patients with diffuse lung emphysema who, after having received the golden standard treatment (pulmonary rehabilitation), continue to present respiratory failure with disabling dyspnea. ten patients with severe lung hyperinflation will be evaluated. the method proposed is designed to create alternative expiratory passages for air trapped in the emphysematous lung by draining the lung parenchyma, thereby establishing communication between the alveoli and the external environment. the ten patients selected will be required to meet the inclusion criteria and to give written informed consent. those ten patients will be included in the study pending the approval of the ethics in research committee of the s?o paulo santa casa school of medicine, s?o paulo, brazil. the protocol we will employ in order to evaluate the proposed procedure is feasible and will show whether debilitated patients suffering from diffuse pulmonary emphysema can benefit from this procedure, which could represent an alternative to lung transplant or lung volume reduction surgery, the only options currently available.

Gon?alves, Roberto;Saad Junior, Roberto;Dorgan Neto, Vicente;Botter, Marcio;
Jornal Brasileiro de Pneumologia , 2008, DOI: 10.1590/S1806-37132008000600014
Abstract: here, we describe two cases of lung metastasis of adamantinoma of long bones, a low-grade bone neoplasm that rarely metastasizes. in both cases, the clinical presentation of the metastases was characterized by spontaneous pneumothorax secondary to tumor cavitation, a phenomenon described in only three of the studies reviewed in the literature. clinical, radiological, and anatomopathological findings, as well as the procedures adopted in the two cases, are described.
Lipossarcoma de mediastino: relato de caso
Saad Junior, Roberto;Dorgan Neto, Vicente;Gon?alves, Roberto;Botter, Márcio;Siqueira, Leticia Cristina Dalledone;
Jornal Brasileiro de Pneumologia , 2008, DOI: 10.1590/S1806-37132008000100010
Abstract: here, we describe the case of a 51-year-old female with mediastinal liposarcoma. liposarcoma is the most common malignant mesenchymal neoplasm in adults, although a mediastinal location is extremely rare. it has a large volume and varied histologic subtypes. it is characterized by the compression of neighboring structures. computed tomography and magnetic resonance imaging provide useful data for diagnosis. tissue biopsy and histological typing are very important in determining the treatment and are needed for the final diagnosis. radiotherapy and chemotherapy are ineffective treatment modalities. according to the literature, surgical resection is the treatment of choice. long-term follow-up evaluation is indicated since there is a high rate of recurrence.

Jornal Brasileiro de Pneumologia , 2009, DOI: 10.1590/S1806-37132009000100003
Abstract: objective: to report the results obtained in three patients with diffuse pulmonary emphysema during the pre- and post-operative periods following a new surgical technique: collateral ventilation with lung parenchyma drainage. methods: patients suffering from pulmonary failure and disabling dyspnea, despite having received the gold standard treatment, including pulmonary rehabilitation, were selected for the evaluation of pulmonary drainage. during the pre- and post-operative periods, patients were submitted to plethysmography and six-minute walk tests, as well as completing the following quality of life questionnaires: medical outcomes study 36-item short-form health survey, saint george's respiratory questionnaire, eastern cooperative oncology group performance status and medical research council scale. in all three cases, the postoperative follow-up period was at least 300 days. the tests were performed at the following time points: during the pre-operative period; between post-operative days 30 and 40; and on post-operative day 300. data were analyzed using profile plots of the means. results: when the results obtained in the pre-operative period were compared to those obtained at the two post-operative time points evaluated, improvements were observed in all parameters studied. conclusions: the results suggest that the surgical technique proposed for the treatment of patients suffering from severe diffuse emphysema successfully reduces the debilitating symptoms of these patients, improving their quality of life considerably.
Tratamento operatório de bolhas no enfisema bolhoso: uma simples drenagem
Jornal de Pneumologia , 2000, DOI: 10.1590/S0102-35862000000300003
Abstract: ten surgeries have been performed on 8 patients for the relief of symptoms due to bullous disease. closed intubation drainage of the bullae was used in all patients under local anesthesia. the technique, initially devised by monaldi for the treatment of intrapulmonary tuberculous abscesses was modified. symptomatic improvement and total collapse of the bullae was reported by 9 of the 10 procedures. the technique described provides a simple method for decompressing bullae by means of a minimally invasive surgical procedure. it has proved a suitable approach for all but those with the poorest lung function and is now the author's treatment of choice. techniques using intracavitary intubation have potential advantages: no lung tissue is removed, in addition, the limited incision and a local anesthesia needed for the procedure are better tolerated by patients with poor lung function.

Abstract: OBJETIVO: Descrever a técnica operatória da drenagem pulmonar através do estudo anat mico em cadáveres, determinar se o local definido para a drenagem pulmonar é adequado e seguro, e determinar a rela o anat mica do tubo de drenagem com a parede torácica, pulm es, grandes vasos e mediastino. MéTODOS: Foram dissecados 30 cadáveres de ambos os sexos, fornecidos pelo Necrotério do Hospital Central da Santa Casa de S o Paulo, em S o Paulo (SP) no período entre maio e novembro de 2011. Foi inserido um dreno de a o de 7,5 cm com 24 F de diametro no segundo espa o intercostal, na linha médio-clavicular, bilateralmente, e foi medida a distancia do dreno com as seguintes estruturas: br nquios principais, br nquios dos lobos superiores, vasos subclávios, artérias pulmonares, artérias pulmonares do lobo superior, veia pulmonar superior, veia ázigos e aorta. Foram realizadas medi es de peso, altura, diametro laterolateral do tórax, diametro posteroanterior do tórax e espessura da parede torácica de cada cadáver. RESULTADOS: Dos 30 cadáveres dissecados, 20 e 10 eram do sexo masculino e feminino, respectivamente. A média da extremidade distal do dreno com os br nquios principais direito e esquerdo foi de 7,2 cm. CONCLUS ES: A utiliza o de um dreno torácico de tamanho fixo na posi o preconizada é factível e segura, independentemente das características antropométricas do paciente. OBJECTIVE: A cadaver-based study was carried out in order to describe the pulmonary drainage surgical technique, to determine whether the site for the insertion of the chest tube is appropriate and safe, and to determine the anatomical relationship of the chest tube with the chest wall, lungs, large blood vessels, and mediastinum. METHODS: Between May and November of 2011, 30 cadavers of both genders were dissected. The cadavers were provided by the Santa Casa de S o Paulo Central Hospital Mortuary, located in the city of S o Paulo, Brazil. A 7.5-cm, 24 F steel chest tube was inserted into the second intercostal space along the midclavicular line bilaterally, and we measured the distances from the tube to the main bronchi, upper lobe bronchi, subclavian vessels, pulmonary arteries, pulmonary arteries in the upper lobe, superior pulmonary vein, azygos vein, and aorta. Weight, height, and chest wall thickness, as well as laterolateral and posteroanterior diameters of the chest, were measured for each cadaver. RESULTS: Of the 30 cadavers dissected, 20 and 10 were male and female, respectively. The mean distance between the distal end of the tube and the main bronchi (right and left) was 7.2

Revista da Associa??o Médica Brasileira , 2007, DOI: 10.1590/S0104-42302007000300018
Abstract: objective: lack of brazilian publications regarding this disease in brazil led us to perform the current work to describe the historical evolution and to analyze results of the surgical treatment of giant emphysematous lung bullae at the santa casa de s?o paulo. methods: we have retrospectively assessed, between january 1979 and june 2005, the medical records of 83 patients submitted to one of four surgical modalities: the thoracoscopic bullectomy, vats bullectomy, vats bullae drainage and bullae drainage with local anesthesia, totaling 92 surgeries. parameters analyzed were hospitalization time, post-surgical complications, perioperative and late mortality in addition to clinical and functional pre- and post- surgical parameters. results: morbidity was 40.2% and early post-surgical mortality 4.3%. post-surgical complications were associated to the patient's morbid history. factors such as diffuse pulmonary emphysema, multiple bullae and age did not influence early complications. there was an improvement in the symptomatology and functional results in 94.5% of the patients. there was no return on he operated bullae. mortality five years after surgery was of 18.3% and arose, primarily from clinical progression of the diffuse pulmonary emphysema. conclusions: several surgical modalities were performed to treat the emphysematous lung bullae, from bullectomy to thoracotomy, at the initial phase until drainage of the bullae with local anesthesia and sprayed talc, the currently preferred modality. regardless of the method used, however, notwithstanding the relatively high morbidity, post-surgical results are highly favorable with low mortality and uncontestable clinical-functional improvement of the operated patients.
