ABSTRACT
El trasplante de pulmón (TP) es una opción para pacientes pediátricos con enfermedades pulmonares terminales. OBJETIVO: Evaluar resultados y sobrevida de pacientes pediátricos trasplantados de pulmón. MÉTODOS: Análisis retrospectivo de registros clínicos de pacientes TP ≤ 15 años de Clínica Las Condes. Se analizaron datos demográficos, tipo de trasplante, función pulmonar basal y post trasplante, complicaciones precoces y tardías y sobrevida. RESULTADOS: Nueve pacientes < 15 años de edad se han trasplantado. La edad promedio fue 12,7 años. La principal indicación fue fibrosis quística (7 pacientes). El IMC promedio fue de 17,6 y todos estaban con oxígeno domiciliario. El 77% utilizó soporte extracorpóreo intraoperatorio. Las principales complicaciones precoces fueron hemorragia y la disfunción primaria de injerto mientras que las tardías fueron principalmente las infecciones y la disfunción crónica de injerto. Cuatro pacientes han fallecido y la sobrevida a dos años fue de 85%. El trasplante les permitió una reinserción escolar y 3 lograron completar estudios universitarios. CONCLUSIÓN: El trasplante pulmonar es una alternativa para niños con enfermedades pulmonares avanzadas mejorando su sobrevida y calidad de vida.
Lung transplantation (TP) is a treatment option in children with terminal lung diseases. OBJECTIVE: To evaluate the results and survival of pediatrics lung transplant patients. METHODS: Retrospective analysis of clinical records of lung transplantation of patients ≤ 15 years from Clínica Las Condes, Santiago, Chile. Demographic data, type of transplant, baseline and post transplant lung function, early and late complications and survival rate were analyzed. RESULTS: Nine patients ≤ 15 years-old were transplanted. The average age at transplant was 12.7 years. The main indication was cystic fibrosis (7 patients). The average BMI was 17.6 and all the patients were with home oxygen therapy. 77% used extracorporeal intraoperative support. Average baseline FEV1 was 25.2% with progressive improvement in FEV1 of 77% in the first year. The main early complications were hemorrhage and primary graft dysfunction, while late complications were infections and chronic graft dysfunction. Four patients have died and the estimated 2 years survival was 85%. They achieved school reinsertion and three managed to complete university studies. CONCLUSION: Lung transplantation is an alternative for children with advanced lung diseases improving their survival and quality of life.

ABSTRACT Objective: The objective of this study was to describe the results of anatomic pulmonary resections performed by video-assisted thoracoscopy in Brazil. Methods: Thoracic surgeons (members of the Brazilian Society of Thoracic Surgery) were invited, via e-mail, to participate in the study. Eighteen surgeons participated in the project by providing us with retrospective databases containing information related to anatomic pulmonary resections performed by video-assisted thoracoscopy. Demographic, surgical, and postoperative data were collected with a standardized instrument, after which they were compiled and analyzed. Results: The surgeons provided data related to a collective total of 786 patients (mean number of resections per surgeon, 43.6). However, 137 patients were excluded because some data were missing. Therefore, the study sample comprised 649 patients. The mean age of the patients was 61.7 years. Of the 649 patients, 295 (45.5%) were male. The majority-521 (89.8%)-had undergone surgery for neoplasia, which was most often classified as stage IA. The median duration of pleural drainage was 3 days, and the median hospital stay was 4 days. Of the 649 procedures evaluated, 598 (91.2%) were lobectomies. Conversion to thoracotomy was necessary in 30 cases (4.6%). Postoperative complications occurred in 124 patients (19.1%), the most common complications being pneumonia, prolonged air leaks, and atelectasis. The 30-day mortality rate was 2.0%, advanced age and diabetes being found to be predictors of mortality. Conclusions: Our analysis of this representative sample of patients undergoing pulmonary resection by video-assisted thoracoscopy in Brazil showed that the procedure is practicable and safe, as well as being comparable to those performed in other countries.
RESUMO Objetivo: O objetivo deste estudo foi descrever os resultados de ressecções pulmonares anatômicas por videotoracoscopia no Brasil. Métodos: Cirurgiões torácicos (membros da Sociedade Brasileira de Cirurgia Torácica) foram convidados, por correio eletrônico, a participar do estudo. Dezoito cirurgiões participaram do projeto enviando seus bancos de dados retrospectivos referentes a ressecções anatômicas de pulmão por videotoracoscopia. Dados demográficos, cirúrgicos e pós-operatórios foram coletados em um instrumento padronizado e posteriormente compilados e analisados. Resultados: Dados referentes a 786 pacientes foram encaminhados (média de 43,6 ressecções por cirurgião), sendo 137 excluídos por informações incompletas. Logo, 649 pacientes constituíram nossa população estudada. A média de idade dos pacientes foi de 61,7 anos, 295 eram homens (45,5%), e a maioria - 521 (89,8%) - foi submetida à cirurgia por neoplasia, mais frequentemente classificada como estádio IA. A mediana do tempo de drenagem pleural foi de 3 dias, e a do tempo de internação, 4 dias. Dos 649 procedimentos realizados, 598 (91,2%) foram lobectomias. A taxa de conversão para toracotomia foi de 4,6% (30 casos). Complicações pós-operatórias ocorreram em 124 pacientes (19,1%), sendo pneumonia, escape aéreo prolongado e atelectasia as mais frequentes. A mortalidade em 30 dias foi de 2,0%, tendo como preditores idade avançada e diabetes. Conclusões: A casuística brasileira mostra que as ressecções pulmonares por cirurgia torácica videoassistida são factíveis e seguras, além de comparáveis àquelas de registros internacionais.

ABSTRACT Lung transplantation is a well-established treatment for patients with advanced lung disease. The evaluation of a candidate for transplantation is a complex task and involves a multidisciplinary team that follows the patient beyond the postoperative period. Currently, the mean time on the waiting list for lung transplantation in the state of São Paulo, Brazil, is approximately 18 months. For Brazil as a whole, data from the Brazilian Organ Transplant Association show that, in 2014, there were 67 lung transplants and 204 patients on the waiting list for lung transplantation. Lung transplantation is most often indicated in cases of COPD, cystic fibrosis, interstitial lung disease, non-cystic fibrosis bronchiectasis, and pulmonary hypertension. This comprehensive review aimed to address the major aspects of lung transplantation: indications, contraindications, evaluation of transplant candidates, evaluation of donor candidates, management of transplant recipients, and major complications. To that end, we based our research on the International Society for Heart and Lung Transplantation guidelines and on the protocols used by our Lung Transplant Group in the city of São Paulo, Brazil.
RESUMO O transplante pulmonar é uma terapia bem estabelecida para pacientes com doença pulmonar avançada.A avaliação do candidato para o transplante é uma tarefa complexa e envolve uma equipe multidisciplinar que acompanha o paciente para além do período pós-operatório.O tempo médio atual em lista de espera para transplante pulmonar é de aproximadamente 18 meses no estado de São Paulo. Em 2014, dados da Associação Brasileira de Transplante de Órgãos mostram que 67 transplantes pulmonares foram realizados no Brasil e que 204 pacientes estavam na lista de espera para transplante pulmonar.O transplante pulmonar é principalmente indicado no tratamento de DPOC, fibrose cística, doença intersticial pulmonar, bronquiectasia não fibrocística e hipertensão pulmonar.Esta revisão abrangente teve como objetivos abordar os aspectos principais relacionados ao transplante pulmonar: indicações, contraindicações, avaliação do candidato ao transplante, avaliação do candidato doador, gestão do paciente transplantado e complicações maiores. Para atingirmos tais objetivos, utilizamos como base as diretrizes da Sociedade Internacional de Transplante de Coração e Pulmão e nos protocolos de nosso Grupo de Transplante Pulmonar localizado na cidade de São Paulo.

To evaluate the access to drugs for hypertension and diabetes and the direct cost of buying them among users of the Family Health Strategy (FHS) in the state of Pernambuco, Brazil. Population-based, cross-sectional study of a systematic random sample of 785 patients with hypertension and 823 patients with diabetes mellitus who were registered in 208 randomly selected FHS teams in 35 municipalities of the state of Pernambuco. The selected municipalities were classified into three levels with probability proportional to municipality size (LS, large-sized; MS, medium-sized; SS, small-sized). To verify differences between the cities, we used the χ2 test. Pharmacological treatment was used by 91.2% patients with hypertension whereas 85.6% patients with diabetes mellitus used oral antidiabetic drugs (OADs), and 15.4% used insulin. The FHS team itself provided antihypertensive medications to 69.0% patients with hypertension, OADs to 75.0% patients with diabetes mellitus, and insulin treatment to 65.4%. The 36.9% patients with hypertension and 29.8% with diabetes mellitus that had to buy all or part of their medications reported median monthly cost of R$ 18.30, R$ 14.00, and R$ 27.61 for antihypertensive drugs, OADs, and insulin, respectively. It is necessary to increase efforts to ensure access to these drugs in the primary health care network.
Avaliar o acesso a medicamentos para hipertensão e diabetes e o gasto direto relacionado à aquisição destes insumos entre os usuários da Estratégia Saúde da Família (ESF), no estado de Pernambuco. Estudo transversal, de base populacional, numa amostra aleatória sistemática de 785 pacientes hipertensos e 823 diabéticos cadastrados em 208 equipes da ESF sorteadas em 35 municípios do estado de Pernambuco. Os municípios selecionados foram classificados em três estratos com probabilidade proporcional ao tamanho do município (GP: grande porte; MP: médio porte; PP: pequeno porte). A fim de verificar diferenças entre os municípios, foi utilizado o teste χ2. Dos 785 hipertensos, 91,2% referiram o uso de anti-hipertensivos e dos 823 diabéticos, 85,6% utilizavam antidiabéticos orais (ADO), e 15,4%, insulina. Os anti-hipertensivos eram fornecidos pelas equipes da ESF para 69,0% dos hipertensos, os ADO, para 75,0% dos diabéticos, e a insulina e insumos, para 65,4%. Os hipertensos (36,9%) e os diabéticos (29,8%) que precisavam comprar os medicamentos referiram um gasto mediano mensal de R$ 18,30, R$ 14,00 e R$ 27,61 para anti-hipertensivos, ADO e insulina, respectivamente. É necessário ampliar os esforços para assegurar o acesso aos medicamentos na rede de atenção primária de saúde.

Médicos clínicos e cirurgiões escolhem as suas áreas de atuação de acordo com perfil psicológico predominante de cada um. Enquanto os cirurgiões tendem a ser mais práticos e objetivos, os clínicos geralmente apresentam mais liberdade de ação e senso de oportunidade. No entanto, o terreno de atuação desses dois profissionais não é perfeitamente delimitado. No caso da pneumologia e cirurgia torácica existem várias situações que apresentam campo para atuação dos dois profissionais, como nos casos de metástases pulmonares, derrames pleurais, nódulos pulmonares, biópsia e transplante de pulmão. Embora não haja uma definição clara do papel de cada ator, a interação dos dois profissionais traz enormes benefícios na condução dos casos.

Traumatic lung herniation is an unusual clinical problem. We present a case of a large left post-traumatic lung hernia on the left, anterior, second intercostal space following blunt chest trauma. An important factor in the etiology of these lesions is the relative lack of muscular support of the anterior part of the chest. This report describes the diagnosis and management of a post-traumatic lung hernia.

Primary lung tumours in children are rare, the most common lesions seen in clinical practice are metastatic disease. The majority of children who present with a primary or secondary pulmonary malignancy will present coincidentally while seeking attention for another medical problem, or with non-specific abnormalities such as cough with collapse or consolidation on the chest x-ray. Primary malignant tumours of the lung are the most common, this group is made up of carcinoid tumours, bronchogenic carcinoma and pleuropulmonary blastoma. Benign primary pulmonary tumours are inflammatory pseudotumour or plasma cell granuloma and hamartoma. Often, the possibility of a primary or secundary pulmonary tumour is considered only when radiographic abnormalities or symptoms persist or fail to respond to therapy, many children are asymptomatic until they have advanced disease, which delays diagnosis even further. The aim of this article is show our experience of two patients with inflammatory pseudotumour and literature review.
Los tumores pulmonares primarios en niños son muy poco frecuentes, siendo más reportadas las lesiones metátasicas. La mayoría de los pacientes que presentan un tumor pulmonar ya sea primario o secundario, son hallazgos de algún examen generalmente imagenológico, como parte del estudio de otras causas o en presencia de síntomas inespecíficos como tos asociada a atelectasia o condensación. Los tumores pulmonares primarios malignos son los más frecuentes, comprenden el tumor carcinoide, carcinoma broncogénico y blastoma pleuropulmonar. Los tumores pulmonares primarios benignos son el seudotumor inflamatorio (sTi) o granuloma de células plasmáticas y el hamartoma. Se debe tener un alto índice de sospecha en el diagnóstico de tumor pulmonar primario o secundario, frente a la persistencia de síntomas o si presenta una lesión en la radiografía de tórax que no se modifica o invade localmente a otros tejidos adyacentes a pesar del tratamiento. El objetivo de este artículo es mostrar nuestra experiencia de 2 pacientes portadores de sTi y hacer una revisión de la literatura.

A progressão do acometimento pulmonar e a evolução para insuficiência respiratória são responsáveis por importante morbimortalidade em pacientes com fibrose cística. O transplante pulmonar está consolidado como tratamento de escolha para diversas pneumopatias em estágios terminais e vem sendo realizado em pacientes com fibrose cística avançada desde a década de 1980. A seleção de pacientes candidatos ao transplante envolve a análise cuidadosa de parâmetros clínicos,fisiológicos e laboratoriais, com atenção a fatores conhecidos de mau prognóstico como: piora acentuada e acelerada dafunção pulmonar, aumento da frequência e gravidade das exacerbações, desnutrição, diabetes melito, hemoptise volumosa,pneumotórax, hipoxemia e hipercapnia em ar ambiente, hipertensão pulmonar e distância reduzida no teste de caminhada de seis minutos. Embora o tema ainda gere controvérsias, a maioria dos centros transplantadores contraindica o transplantepara portadores de Burkholdelia cepacia. A presença de outros germes colonizantes no escarro, ainda que com perfil adverso de sensibilidade aos antibióticos, não costuma impedir a realização do transplante em pacientes com fibrose cística. A avaliação pré-transplante nesta população segue os mesmos padrões das demais indicações, com atenção especial ao suporte nutricional, ao perfil microbiológico e à evolução recente do contexto clínico global e da função pulmonar. Os resultados do transplante pulmonar bilateral na fibrose cística são em regra superiores aos das demais indicações.
Progressive involvement of the lungs and the development of respiratory failure are major causes of morbidity and mortalityin patients with cystic fibrosis. Lung transplantation is a well-established treatment for several end-stage respiratory diseases and it has been successfully performed in cystic fibrosis patients since the 1980s. Patient selection involves careful analysisof clinical, physiologic and laboratorial parameters, with special consideration of well-known adverse prognostic factors suchas: accelerated loss of lung function, increase in frequency and severity of exacerbations, poor nutritional status, diabetes mellitus, massive hemoptysis, pneumothorax, hypoxemia and hypercapnia while breathing room air, pulmonary hypertension,and reduced distance in the 6-minute walk test. Despite some controversy, most transplant centers refuse patients with Burkholderia cepacia for transplantation. Other colonizing pathogens, even with extensive antibiotic resistant patterns, donot, in general, preclude the procedure in patients with cystic fibrosis. Pre-transplant evaluation of this population is similarfor other indications, with special attention to nutritional support, microbiological profile analysis and recent changes of theclinical context and lung function. The results of bilateral lung transplantation for cystic fibrosis are generally better than forother indications.

OBJETIVO: Determinar as principais malformações congênitas pulmonares e os principais métodos diagnósticos utilizados, assim como as indicações de tratamento cirúrgico e os seus resultados em um serviço de referência de cirurgia torácica pediátrica. MÉTODOS: Foram revisados 52 prontuários de pacientes com diagnóstico anatomopatológico de malformações congênitas pulmonares e que foram submetidos à ressecção pulmonar entre janeiro de 1997 e dezembro de 2006. Os critérios de exclusão foram idade > 12 anos e dados clínicos incompletos. A amostra final foi composta de 35 pacientes. RESULTADOS: Nesta amostra, a média de idade foi de 31 meses, com predominância do sexo masculino (n = 21). Os achados anatomopatológicos foram malformação adenomatoide cística (n = 14), enfisema lobar congênito (n = 13), sequestro pulmonar (n = 8), e malformação arteriovenosa (n = 1). A ressecção mais comum foi a lobectomia inferior esquerda (25,71 por cento), seguida por diferentes tipos de segmentectomia (22,85 por cento), lobectomia superior esquerda (22,85 por cento), lobectomia superior direita (14,28 por cento), lobectomia inferior direita (8,57 por cento) e lobectomia média (5,71 por cento). Dos 35 pacientes, 34 (97,14 por cento) foram submetidos à drenagem pleural fechada, com tempo médio de permanência do dreno torácico de 3,9 dias. Dez pacientes (28,5 por cento) apresentaram complicações pós-operatórias. Não houve óbitos nesta série. CONCLUSÕES: A ressecção pulmonar para o tratamento das malformações pulmonares é um procedimento seguro, apresentando baixa morbidade e nenhuma mortalidade em um serviço de referência para doenças pulmonares.
OBJECTIVE: To determine the main congenital lung malformations treated and the principal diagnostic methods employed, as well as the indications for surgical treatment and the results obtained, at a referral facility for pediatric thoracic surgery. METHODS: We reviewed the medical charts of 52 patients anatomopathologically diagnosed with congenital lung malformations and who had been submitted to pulmonary resection between January of 1997 and December of 2006. Exclusion criteria were age > 12 years and incomplete clinical data. The final sample comprised 35 patients. RESULTS: In this sample, the mean age was 31 months, and there was a predominance of males (n = 21). The anatomopathological findings were cystic adenomatoid malformation (n = 14), congenital lobar emphysema (n = 13), pulmonary sequestration (n = 8) and arteriovenous malformation (n = 1). The most common type of lung resection was left lower lobectomy (in 25.71 percent) followed by different types of segmentectomy (in 22.85 percent), left upper lobectomy (in 22.85 percent), right upper lobectomy (in 14.28 percent), right lower lobectomy (in 8.57 percent) and middle lobectomy (in 5.71 percent). Of the 35 patients, 34 (97.14 percent) were submitted to closed pleural drainage, with a mean duration of thoracic drainage of 3.9 days. Ten patients (28.5 percent) presented with postoperative complications. There were no deaths in our sample. CONCLUSIONS: Pulmonary resection for the treatment of congenital lung malformations is a safe procedure, presenting low morbidity and no mortality at a referral facility for pediatric thoracic surgery.

Desde o primeiro transplante pulmonar bem sucedido na década de 80, essa se tornou uma terapia bem estabelecida para pacientes com pneumopatia crônica não-neoplásica em estágio terminal. São pacientes portadores de doença pulmonar obstrutiva crônica, fibrose pulmonar idiopática, fibrose cística e hipertensão pulmonar primária em um estágio no qual a terapia clínica não é mais efetiva. Atualmente, são cerca de 150 centros em todo o mundo realizando mais de 2500 transplantes de pulmão todo ano. O aprimoramento das técnicas cirúrgicas e anestésicas, bem como dos cuidados perioperatórios (terapia intensiva, imunossupressão, profilaxia de infecções) contribuíram para aumentar a sobrevida e a qualidade de vida dos pacientes transplantados. Nessa revisão, abordaremos os critérios de seleção de doadores e receptores, e as técnicas de preservação pulmonar atualmente utilizadas. Também discutiremos a técnica operatória adotada em nossa instituição para a extração e o implante dos órgãos. Por fim, citaremos as estatísticas mais recentes divulgadas pela International Society of Heart and Lung Transplantation, incluindo todos os transplantes realizados até o primeiro semestre de 2008...
Since the first successful lung transplantation in the early 1980s, it has become the mainstay of therapy for patients with end-stage chronic non-neoplastic lung diseases. These are patients with chronic obstructive pulmonary disease, cystic fibrosis, idiopathic pulmonary fibrosis and primary pulmonary hypertension in an advanced stage with no effective response to medical therapy. Currently, there are about 150 centers around the world performing more than 2500 lung transplants each year. The improvement of surgical and anesthetic techniques, as well as perioperative care (intensive care, immunosuppression, infection prophylaxis) has contributed to increase survival and quality of life of lung recipients. In this review we will discuss the selection criteria of donors and recipients, and techniques of lung preservation...

Lung cysts in children are usually of congenital origin. Necrotising pneumonias, trauma, cystic fibrosis and kerosene poisoning may be the cause of acquired cysts in the lungs during childhood. We describe a child who presented with pneumothorax and was later discovered to have a cyst in his right lung. The cyst was resected and on histology found to be of inflammatory origin with no epithelial cell lining i.e. a pseudo-cyst. The immuno-histochemical staining of the inflammatory cells from the pseudo-cyst wall showed them to be predominantly histiocytes i.e:, CD68 antigen positive. The cells showed negative staining for S-100 (marker for Langerhans cells), cytokeratins (epithelial markers) and smooth muscle actins excluding the possibility of histiocytosisX, epithelial and congenital cysts respectively. This case illustrates the occurrence of acquired pulmonary pseudocysts unrelated to known etiologic agents which should be considered in the work-up for pneumothoraces.

OBJETIVO: Avaliar o perfil funcional do esôfago e a prevalência de refluxo gastroesofágico (RGE) em pacientes candidatos a transplante pulmonar. MÉTODOS: Foram analisados prospectivamente, entre junho de 2005 e novembro de 2006, 55 pacientes candidatos a transplante pulmonar da Santa Casa de Misericórdia de Porto Alegre. Os pacientes foram submetidos a esofagomanometria estacionária e pHmetria esofágica ambulatorial de 24 h de um e dois eletrodos antes de serem submetidos ao transplante pulmonar. RESULTADOS: A esofagomanometria foi anormal em 80 por cento dos pacientes e a pHmetria revelou RGE ácido patológico em 24 por cento. Os sintomas digestivos apresentaram sensibilidade de 50 por cento e especificidade de 61 por cento para RGE. Dos pacientes com doença pulmonar obstrutiva crônica, 94 por cento apresentaram alteração à manometria, e 80 por cento apresentaram hipotonia do esfíncter inferior, que foi o achado mais freqüente. Pacientes com bronquiectasias apresentaram a maior prevalência de RGE (50 por cento). CONCLUSÕES: O achado freqüente em pacientes com doença pulmonar avançada é RGE. Na população examinada, a presença de sintomas digestivos de RGE não foi preditiva de refluxo ácido patológico. A contribuição do RGE na rejeição crônica deve ser considerada e requer estudos posteriores para seu esclarecimento.
OBJECTIVE: To assess the esophageal function profile and the prevalence of gastro-esophageal reflux (GER) in lung transplant candidates. METHODS: From July of 2005 to November of 2006, a prospective study was conducted involving 55 candidates for lung transplantation at the Santa Casa de Misericórdia Hospital in Porto Alegre, Brazil. Prior to transplantation, patients underwent outpatient stationary esophageal manometry and 24-h esophageal pH-metry using one and two electrodes. RESULTS: Abnormal esophageal manometry was documented in 80 percent of the patients, and 24 percent of the patients presented pathological acid reflux. Digestive symptoms presented sensitivity and specificity for GER of 50 percent and 61 percent, respectively. Of the patients with chronic obstructive pulmonary disease, 94 percent presented abnormal esophageal manometry, and 80 percent presented lower esophageal sphincter hypotonia, making it the most common finding. Patients with bronchiectasis presented the highest prevalence of GER (50 percent). CONCLUSIONS: In patients with advanced lung disease, GER is highly prevalent. In the population studied, digestive symptoms of GER were not predictive of pathological acid reflux. The role that GER plays in chronic rejection should be examined and clarified in future studies.

El Uruguay es un país con 3 millones de habitantes que no cuenta con un programa de trasplante pulmonar propio. En este contexto se ha optado por generar un acuerdo para su realización en un centro de referencia regional como la Fundación Favaloro de la República Argentina. En este trabajo se muestra la experiencia de este programa durante 4 años. Hasta el momento se han trasplantado 20% de los pacientes alistados y la mortalidaden lista de espera ha sido elevada. La principal limitante ha sido la dificultad para obtener donantes pulmonares óptimos para el implante. La flexibilización en la selección, con la utilización de donantes marginales o la utilización de donantes en asistolia pueden en el futuro mejorar esta situación.
Uruguay, a country with three million- inhabitants does not have its own lung transplant program. Therefore an agreement has been reached for transplants, to be performed in the regional reference center called Favaloro Foundation in Argentine. The experience of the program for the first four years is presented in this paper. Twenty percent of the waiting list patients have been transplanted so far; the mortality of the patients on the waiting list was high. The main limitation of the program has been the difficulty to get optimal lung donors.The selection of donors who either meet marginally the transplant requirements or are in asystolic arrest will make the program more flexible and may improve current results.

Esophageal atresia, congenital diaphragmatic hernia, bronchopulmonary malformations and cystic lung diseases are the common neonatal thoracic surgical lesions encountered in practice. The availability of antenatal ultrasonography has lead to these lesions being detected before birth. Antenatal diagnosis can be made with a fair degree of accuracy in tertiary fetal medicine centres. Antenatal intervention is limited in a very few centres in the western world and not being done in India at present. The outcome of these babies with antenatal diagnosis of thoracic lesions has changed in the last decade. Earlier intervention is now possible in cystic lung disease before infectious complication has set in. All these lesions are managed exclusively in well developed neonatal surgery units with excellent outcome in the western world. The present study reviews the antenatal detection, clinical presentation, interventional/surgical procedures [antenatally and postnatally] and outcome of these common neonatal thoracic surgical lesions.

OBJETIVO: Avaliar a drenagem pleural através de válvula unidirecional de tórax no pós-operatório de ressecção pulmonar eletiva. MÉTODOS: Foram realizadas 39 ressecções pulmonares, de forma prospectiva e com análise descritiva, em pacientes que utilizaram a válvula unidirecional de tórax (VUT) como o método de drenagem pleural durante o período pós-operatório. Foram excluídos os pacientes com idade inferior a 12 anos, os submetidos à pneumectomia ou a operação de urgência, os que não completaram o seguimento do estudo e os pacientes que utilizaram o sistema de frasco em selo d'água como método inicial de drenagem pleural. Observou-se a expansão pulmonar, o tempo de permanência com o sistema de drenagem, o período de internação e as complicações pós-operatórias. RESULTADOS: Neste estudo, foram incluídos e analisados 36 pacientes. A média de permanência com o sistema de drenagem pleural foi de 3,0 ± 1,6 dias. O laudo da radiografia de tórax, realizado após 30 dias do procedimento cirúrgico foi considerado normal em 34 (95,2 por cento) pacientes. Ocorreram oito (22,4 por cento) casos de complicações pós-operatórias, sendo três (8,4 por cento) relacionadas à VUT. CONCLUSÕES: A utilização da VUT no pós-operatório de ressecção pulmonar eletiva foi eficiente, bem tolerada e apresentou baixo índice de complicação.
OBJECTIVE: To evaluate pleural drainage using a one-way flutter valve following elective lung resection. METHODS: This was a prospective study, with descriptive analysis, of 39 lung resections performed using a one-way flutter valve to achieve pleural drainage during the postoperative period. Patients less than 12 years of age were excluded, as were those submitted to pneumonectomy or emergency surgery, those who were considered lost to follow-up and those in whom water-seal drainage was used as the initial method of pleural drainage. Lung expansion, duration of the drainage, hospital stay and postoperative complications were noted. RESULTS: A total of 36 patients were included and analyzed in this study. The mean duration of pleural drainage was 3.0 ± 1.6 days. At 30 days after the surgical procedure, chest X-ray results were considered normal for 34 patients (95.2 percent). Postoperative complications occurred in 8 patients (22.4 percent) and were related to the drainage system in 3 (8.4 percent) of those. CONCLUSIONS: The use of a one-way flutter valve following elective lung resection was effective, was well tolerated and presented a low rate of complications.
