Hidatidosis pulmonar: comparación de los resultados de la cirugía con y sin capitonaje mediante Propensity Score Matching / Pulmonary hydatidosis: comparison results of surgery with capitonnage versus surgery without capitonnage using Propensity Score Matching

Resumen Introducción: El tratamiento de elección del Quiste Hidatídico Pulmonar (QHP) es la resección quirúrgica. Actualmente, existe controversia sobre la superioridad de la cirugía con capitonaje (CC) versus la cirugía sin capitonaje (SC). Objetivo: Comparar los resultados de la cirugía conservadora CC y SC mediante Propensity Score Matching (PSM). Materiales y Método: Se realizó un estudio analítico retrospectivo de los pacientes con QHP tratados quirúrgicamente en el Hospital Guillermo Grant Benavente, Concepción, Chile; entre enero-1995 y diciembre-2018. Se realizó un PSM con una relación 1:1 entre los pacientes operados con la técnica CC y SC. Posterior al PSM se balancearon las características basales. Resultados: Total 205 episodios de QHP en el período. Se realizó cirugía conservadora en 165 casos, 101 CC y 64 SC. Posterior al emparejamiento se obtuvieron 53 pacientes operados CC y 53 SC. No se observaron diferencias significativas en la presencia de fuga aérea persistente (CC = 9,4%; SC = 11,3%, p 0,75), empiema (CC = 3,8%; SC = 0%, p 0,49), días con pleurotomía (CC = 9,1 ± 8,9; SC 10,1 ± 10,7, p 0,39, mediana 6 versus 6 días, respectivamente), ni días de estadía posoperatoria (CC = 10,4 ± 9,0; SC = 11,7 ± 11,9, p 0,22, mediana 7 versus 7 días, respectivamente). Conclusiones: La cirugía SC demostró resultados comparables a la técnica CC en el tratamiento quirúrgico conservador del QHP.

Background: The treatment of choice for Pulmonary Hydatid Cys (PHC) is surgical resection. There is currently controversy about the superiority of surgery with capitonage (SC) versus surgery without it (SWC). Aim: To compare the results of conservative surgery with capitonnage and versus surgery without capitonnage using Propensity Score Matching (PSM). Materials and Method: A retrospective analytical study was carried out with patients with PHC treated surgically at the Guillermo Grant Benavente Hospital, Concepción, Chile, between January-1995 and December-2018. A PSM was performed with a 1:1 ratio. Results: Conservative surgery was done in 165 cases, 101 SC and 64 SWC. After matching, 53 SC and 53 SWC operated patients were obtained. No significant differences were observed in the presence of persistent air leak (9.4% vs11.3%, SC vs SWC respectively, p 0.75), empyema (3.8% vs 0%, p 0.49), days with pleurotomy (9.1 ± 8.9 vs 10.1 ± 10.7, p 0.39), nor days of postoperative stay (10.4 ± 9.0 vs 11.7 ± 11.9, p 0.22). Conclusión: The SWC demonstrated comparable results to the SC technique in the conservative surgical treatment of PHC.

Predictive value of plasma cytokines for acute kidney injury following lung resection surgery: prospective observational study / Valor preditivo das citocinas plasmáticas para lesão renal aguda após cirurgia de ressecção pulmonar: estudo observacional prospectivo

Abstract Background and objectives: Patients undergoing lung resection surgery are at risk of developing postoperative acute kidney injury. Determination of cytokine levels allows the detection of an early inflammatory response. We investigated any temporal relationship among perioperative inflammatory status and development of acute kidney injury after lung resection surgery. Furthermore, we evaluated the impact of acute kidney injury on outcome and analyzed the feasibility of cytokines to predict acute kidney injury. Methods: We prospectively analyzed 174 patients scheduled for elective lung resection surgery with intra-operative periods of one-lung ventilation periods. Fiberoptic broncho-alveolar lavage was performed in each lung before and after one-lung ventilation periods for cytokine analysis. As well, cytokine levels were measured from arterial blood samples at five time points. acute kidney injury was diagnosed within 48 h of surgery based on acute kidney injury criteria. We analyzed the association between acute kidney injury and cardiopulmonary complications, length of intensive care unit and hospital stays, intensive care unit re-admission, and short-term and long-term mortality. Results: The incidence of acute kidney injury in our study was 6.9% (12/174). Acute kidney injury patients showed higher plasma cytokine levels after surgery but differences in alveolar cytokines were not detected. Although no patient required renal replacement therapy, acute kidney injury patients had higher incidence of cardiopulmonary complications and increased overall mortality. Plasma interleukin-6 at 6 h was the most predictive cytokine of acute kidney injury (cut-off point at 4.89 pg.mL-1). Conclusions: Increased postoperative plasma cytokine levels are associated with acute kidney injury after lung resection surgery in our study, which worsens the prognosis. Plasma interleukin-6 may be used as an early indicator for patients at risk of developing acute kidney injury after lung resection surgery.

Resumo Justificativa e objetivos: Os pacientes submetidos à cirurgia de ressecção pulmonar apresentam risco de desenvolver lesão renal aguda pós-operatória. A determinação dos níveis de citocinas permite detectar uma resposta inflamatória precoce. Investigamos a relação temporal entre o estado inflamatório perioperatório e o desenvolvimento de lesão renal aguda após cirurgia de ressecção pulmonar. Além disso, avaliamos o impacto da lesão renal aguda no desfecho e analisamos a viabilidade das citocinas para prever este tipo de lesão. Métodos: No total, foram analisados prospectivamente 174 pacientes agendados para cirurgia eletiva de ressecção pulmonar com períodos intraoperatórios de ventilação monopulmonar. Lavado bronco-alveolar com fibra óptica foi realizado em cada pulmão antes e após os períodos de ventilação monopulmonar para análise das citocinas. Os níveis de citocina foram medidos a partir de amostras de sangue arterial em cinco momentos. A lesão renal aguda foi diagnosticada dentro de 48 horas após a cirurgia, com base nos critérios para sua verificação. Analisamos a associação entre lesão renal aguda e complicações cardiopulmonares, tempo de internação em unidade de terapia intensiva e de internação hospitalar, reinternação em unidade de terapia intensiva e mortalidade a curto e longo prazos. Resultados: A incidência de lesão renal aguda no estudo foi de 6,9% (12/174). Os pacientes com lesão renal aguda apresentaram níveis mais altos de citocinas plasmáticas após a cirurgia, mas não foram detectadas diferenças nas citocinas alveolares. Embora nenhum paciente tenha precisado de terapia renal substitutiva, os com lesão renal aguda apresentaram maior incidência de complicações cardiopulmonares e aumento da mortalidade geral. A interleucina-6 plasmática em seis horas foi a citocina mais preditiva de lesão renal aguda (ponto de corte em 4,89 pg.mL-1). Conclusões: O aumento dos níveis plasmáticos de citocinas no pós-operatório está associado à lesão renal aguda após cirurgia de ressecção pulmonar no estudo, o que piora o prognóstico. A interleucina-6 plasmática pode ser usada como um indicador precoce para pacientes com risco de desenvolver lesão renal aguda após cirurgia de ressecção pulmonar.

Selective lobar blockade with a Coopdech blocker combined with a double-lumen endotracheal tube for lung metastases resection by laser / Bloqueio lobar seletivo com um bloqueador Coopdech combinado com um tubo endotraqueal de duplo lúmen para ressecção de metástases pulmonares com laser

Abstract In recent years, laser resection of lung metastases has been established as the standard procedure worldwide. To avoid airway fire, it is necessary to collapse the surgical lung. The selective lobar bronchial blockade is a technique that allows one-lung ventilation while the operated lobe is collapsed in patients with previous pulmonary resection requiring subsequent resection or with limited pulmonary reserve. We report a clinical case about our experience of a selective lobar bronchial blockade technique with a bronchial blocker (Coopdech endobronchial blocker) that was employed successfully with a double-lumen endotracheal tube in a patient with previous contralateral pulmonary resection who was scheduled for atypical resections of pulmonary metastases by laser. We selectively blocked the right intermediate bronchus for management of hypoxemia during one-lung ventilation. This technique provided adequate ventilation and oxygenation during surgery, avoiding the need of two-lung ventilation during lung metastases resection by laser. Conclusion: This case shows that if a properly positioned double-lumen tube was already in place and the patient does not tolerate one-lung ventilation because of hypoxemia, it would be possible to provide selective lobar blockade by placing a bronchial blocker through the lumen of the double-lumen tube, avoiding the use of continuous positive airway pressure during laser surgery. This technique does not disturb the operative field or interrupt the operative procedure during resection by laser, which would occur during two-lung ventilation or used of continuous positive airway pressure.

Resumo Nos últimos anos, a ressecção de metástases pulmonares com o uso de laser foi estabelecida como o procedimento padrão em todo o mundo. Para evitar queimadura das vias aéreas, o colapso cirúrgico do pulmão é necessário. O bloqueio brônquico seletivo é uma técnica que permite a ventilação de um lobo, enquanto o lobo operado é colapsado nos pacientes com ressecção pulmonar anterior que requerem ressecção subsequente ou que possuem reserva pulmonar limitada. Relatamos um caso clínico de nossa experiência com a técnica de bloqueio brônquico seletivo com bloqueador brônquico (bloqueador endobrônquico Coopdech), usado com sucesso com um tubo endotraqueal de duplo lúmen em um paciente com ressecção pulmonar contralateral prévia, agendado para ressecção atípica de metástases pulmonares com o uso de laser. Seletivamente bloqueamos o brônquio intermediário direito para o controle de hipoxemia durante a ventilação monopulmonar. Essa técnica proporcionou ventilação e oxigenação adequadas durante a cirurgia, evitando a necessidade de ventilar os dois pulmões durante a ressecção de metástases pulmonares com o uso de laser. Conclusão: Este caso mostra que, se um tubo de duplo lume estiver corretamente posicionado e o paciente não tolerar a ventilação monopulmonar devido à hipoxemia, seria possível fornecer bloqueio lobar seletivo com a colocação de um bloqueador brônquico através do lume do tubo de duplo lume, evitando o uso de pressão positiva contínua de vias aéreas (PPCVA) durante a cirurgia a laser. Essa técnica não interfere no campo operatório ou interrompe o procedimento durante a ressecção por laser, que poderia ocorrer durante a ventilação dos dois pulmões ou uso de PPCVA.

Prophylactic Pulmonary Artery Reduction in a Young Female with Severe Pulmonary Hypertension from Complete Atrioventricular Septal Defect

Management of severely dilated pulmonary artery (PA) associated with severe pulmonary hypertension from congenital heart disease remains controversial, primarily due to its rare nature and concern for perioperative unpredictable complications. Herein, we report a 25 year-old female with a severely dilated PA (up to 73 mm), who was successfully treated by a PA graft replacement by creating a Y-shaped conduit using a 28 mm hemashield tube in the main PA and a 20 mm hemashield tube in both proximal parts of the branch PA.

Comparison of efficacy of different treatments for pulmonary embolism / 华中科技大学学报（医学）（英德文版）

An optimal therapy for pulmonary embolism (PE) was explored by comparing three different methods in order to alleviate the sufferings of PE patients and reduce the mortality. Eighty patients with PE diagnosed by computed tomography angiography (CTA) were treated with thrombolysis, anticoagulation only, or surgery/intervention. The clinical efficacy of different treatments were compared and analyzed. Twenty-four out of the 26 patients (92%) in anticoagulation only group showed improvement in CTA and clinical presentations, which was significantly higher than that in the thrombolysis group (87%, n=39, P<0.05). However, there was no significant difference in the rate of mortality between thrombolysis group and anticoagulation only group. In the surgery/interventional group (n=15), the success rate was 47%, and the mortality rate was 14%. Both of them were significantly different from those in thrombolysis and anticoagulation only groups (both P<0.05). Log-rank analysis of the data of 5-year follow-up revealed that the survival time in surgery/intervention group was significantly shorter than in the other two groups (P<0.05). It was suggested that it is of importance to choose the appropriate therapeutic regimen for PE patients. Mortality may be reduced and prognosis may be improved with anticoagulation only and thrombolysis therapy.

Avaliação da qualidade de vida, função pulmonar, e capacidade de exercício de pacientes com bronquiectasia não fibrocística antes e após cirurgia de ressecção pulmonar / Quality of life, pulmonary function and exercise capacity assessment of patients with non-cystic fibrosis (CF) bronchiectasis before and after pulmonary resection surgery

O papel da ressecção pulmonar em controlar as complicações e períodos de exacerbação de sintomas em pacientes com bronquiectasia é bem descrito na literatura. No entanto, não existem estudos com um instrumento objetivo e validado para avaliação de qualidade de vida no pós-operatório desses pacientes. OBJETIVO: Avaliar a qualidade de vida de pacientes com diagnóstico clínico e radiológico de bronquiectasia não fibrocística, ainda sintomáticas após o tratamento clínico adequado, antes e após a ressecção das áreas bronquiectásicas mais afetadas. MÉTODOS: Estudo longitudinal prospectivo, realizado entre 2010 e 2013. Foram incluídos todos os pacientes encaminhados ao ambulatório de Cirurgia Torácica com diagnóstico de bronquiectasia que apresentavam ausência de resposta ao tratamento clínico adequado após 1 ano de seguimento e/ou presença de complicações da doença. Foram avaliadas qualidade de vida por meio de dois questionários - SF36v2 e WHOQOL, função de pulmonar completa e capacidade de exercício dos indivíduos antes a após a ressecção da área pulmonar mais comprometida pela bronquiectasia. RESULTADOS: Sessenta e um pacientes foram incluídos consecutivamente no estudo. Oito pacientes foram excluídos por diversas razões. Após isso, 53 pacientes (50,9% do sexo masculino, com idade 41,3 anos, ± 12,9) foram submetidos a cirurgia, mas apenas 44 completaram os nove meses de follow-up. A tuberculose foi a causa de bronquiectasias em 60,4% dos pacientes e 26,4% apresentavam doença bilateral, mas apenas a área mais afetada foi ressecada. Os resultados cirúrgicos foram pneumonectomia (direita 3 - 5,7% / esquerda 6 - 11,3%), lobectomia superior (direito 13 - 24,5% / esquerda 10 - 18,9%), lobectomia média (5 - 9,4%) e lobectomia inferior (direito 6 - 11,3% / esquerda 10 -18,9%). Dois pacientes apresentaram complicações graves e morreram e, além disso, treze pacientes (24,5%) tiveram complicações clínicas e cirúrgicas. Após a ressecção do pulmão, os pacientes...

The role of pulmonary resection in controlling complications and periods of exacerbation of symptoms in patients with bronchiectasis is well described in the literature. However, there are no studies with an objective and validated instrument for assessing quality of life in the postoperative period in these patients. OBJECTIVE: To evaluate the quality of life measured after resection of bronquiectásicas areas in patients with clinical and radiological diagnosis of bronchiectasis non-fibrocystic and persistent symptoms after appropriate clinical treatment. METHODS: This is a prospective longitudinal study conducted between 2010 and 2013. We included all patients referred to our outpatient clinic during the study period with symptomatic bronchiectasis and failed medical treatment. We assessed quality of life through two questionnaires - SF36v2 and WHOQOL, complete lung function and exercise capacity of individuals before and after resection of lung area most affected by bronchiectasis. RESULTS: Sixty-one patients were sequentially enrolled in the study. Eight patients were excluded for several reasons. After that, 53 patients (50.9% male; age 41.3 years, ± 12.9) underwent surgical resection, but only 44 complete the nine months of follow-up. Tuberculosis is the cause of bronchiectasis in 60.4% of the patients and 26.4% has bilateral disease, but only the most affected area was resected. The surgical outcomes are pneumonectomy (right 3 - 5.7% and left 6 - 11.3%), Upper lobectomy (right 13 - 24.5% and left 10 - 18.9%), right middle lobectomy (5 - 9.4%) and lower lobectomy (right 6 - 11.3% and left 10 - 18.9%). Two patients had serious complications and died and in addition, thirteen patients (24.5%) had clinical and surgical complications. After lung resection, patients had mildly lower values at spirometry, but because of lower lung volumes, since the FEV1/FVC remained constant. The DLCO was not changed after intervention, suggesting that...

Avaliação da aplicabilidade de dispositivos de correção de defeitos do septo atrial no tratamento endoscópico de deiscências totais crônicas de coto brônquico / Evaluation of cardiac septal defects closure device in endoscopic treatment of chronic total bronchial stump fistulas

As fístulas broncopleurais habitualmente decorrem de procedimentos cirúrgicos de ressecção pulmonar por diversas etiologias, com incidência na literatura de 0% a 28%, e mortalidade de 16% a 72%, sendo mais frequente em homens, e nos casos de pneumonectomia do que em lobectomia. As deiscências totais de coto brônquico apresentam indicação de tratamento cirúrgico, porém a condição clínica destes pacientes geralmente é precária com alto risco anestésico e cirúrgico. Os tratamentos endoscópicos de fístulas broncopleurais até então descritos foram utilizados apenas em fístulas parciais menores que 8 milímetros. Objetivo: Este estudo propõe-se a avaliar a viabilidade do tratamento endoscópico de fístulas totais de coto brônquico utilizando o dispositivo oclusor de defeitos septais cardíacos Occlutech-Fígulla®. Casuística e métodos: Foram incluídos pacientes com fistula broncopleural total secundária a ressecção pulmonar. Os pacientes foram submetidos inicialmente à broncoscopia para avaliação e medida da fístula e a uma cintilografia pulmonar de inalação para documentação do padrão inicial de vazamento. A colocação do dispositivo foi feita através da broncoscopia realizada sob sedo-analgesia com o paciente em ventilação espontânea com suplementação de oxigênio. Os pacientes foram acompanhados durante 12 meses e avaliados quanto à cobertura do dispositivo por tecido cicatricial, fechamento do trajeto fistuloso e desenvolvimento de complicações relacionadas como o deslocamento do dispositivo, lesões de estruturas adjacentes e desenvolvimento de infecção. As análises descritivas dos dados quantitativos com distribuição normal foram apresentadas através das médias acompanhadas dos respectivos desvios padrão. Os dados sem distribuição normal foram apresentados através de suas medianas com os respectivos intervalos interquartil 25-75%. A análise inferencial utilizou a Análise de Variância de Medidas Repetidas para os dados com distribuição normal e os testes...

Bronchopleural fistulas are possible complications following lung resection procedures for different etiologies. The reported incidence is 0 % to 28%, and the related mortality is 16% to 72%. More frequently in men and pneumonectomy cases than lobectomy cases. Total dehiscence of the bronchial stump should be treated by surgical interventions; however, the clinical status of these patients is generally poor with high anesthetic and surgical risks. Endoscopic treatment of bronchopleural fistulas previously described were used only in 8mm or smaller partial fistulas. Objective To evaluate the endoscopic treatment of total bronchial stump fistulas using the Occlutech - Fígulla®, a device used to close cardiac septal defects. Patients and methods: We select patients with total bronchial stump fistula. Patients underwent bronchoscopy for local fistula evaluation and an inhalation lung scintigraphy for the initial leak parameter documentation. The placement of the device was made by bronchoscopy performed under sedation - analgesia with the patient in spontaneous ventilation with oxygen supplementation. Patients were followed for 12 months and assessed for scar tissue coverage device, fistula closure and development of related complications such as displacement device, adjacent structures lesions and infection. The descriptive analysis of quantitative data with normal distribution were presented through the mean along with the related standard deviations. Non-normal distribution data were presented by their medians with their respective interquartile ranges 25-75 %. The inferential analysis used Repeated Measures Analysis of Variance for data with normal distribution and non-parametric tests of Friedman ANOVA to data with nonnormal distribution. It was considered an error probability of a type I (alfa) 0.05. Results: This study evaluated nine patients with a males predominance (77.8% ) with mean age of 45 ± 11.1 years with resections for...

Surgical Treatment for Non-Small Cell Lung Cancer in Patients on Hemodialysis due to Chronic Kidney Disease: Clinical Outcome and Intermediate-Term Results

BACKGROUND: Patients on dialysis undergoing surgery belong to a high-risk group. Only a few studies have evaluated the outcome of major thoracic surgical procedures in dialysis patients. We evaluated the outcomes of pulmonary resection for non-small cell lung cancer (NSCLC) in patients on hemodialysis (HD). METHODS: Between 2008 and 2013, seven patients on HD underwent pulmonary resection for NSCLC at our institution. We retrospectively reviewed their surgical outcomes and prognoses. RESULTS: The median duration of HD before surgery was 55.0 months. Five patients underwent lobectomy and two patients underwent wedge resection. Postoperative morbidity occurred in three patients, including pulmonary edema combined with pneumonia, cerebral infarction, and delirium. There were no instances of in-hospital mortality, although one patient died of intracranial bleeding 15 days after discharge. During follow-up, three patients (one patient with pathologic stage IIB NSCLC and two patients with pathologic stage IIIA NSCLC) experienced recurrence and died as a result of the progression of the cancer, while the remaining three patients (with pathologic stage I NSCLC) are alive with no evidence of disease. CONCLUSION: Surgery for NSCLC in HD patients can be performed with acceptable perioperative morbidity. Good medium-term survival in patients with pathologic stage I NSCLC can also be expected. Pulmonary resection seems to be the proper treatment option for dialysis patients with stage I NSCLC.

The effects of deep and light propofol anesthesia on stress response in patients undergoing open lung surgery: a randomized controlled trial / 대한마취과학회지

BACKGROUND: This prospective, randomized controlled study was undertaken to compare stress hormone response to open thoracotomy for lung resection at different anesthetic depths, as determined by bispectral index (BIS) monitoring, in patients under propofol-remifentanil anesthesia. METHODS: Forty-eight adult patients scheduled for lung resection surgery using one-lung ventilation were randomly assigned to either a deep anesthesia group (BIS score of 40 +/- 5, n = 24) or a light anesthesia group (BIS score of 60 +/- 5, n = 24) by adjusting propofol infusion rates. Blood norepinephrine, epinephrine, adrenocorticotropic hormone, and cortisol levels were measured before the induction of anesthesia, at the end of surgery, and at 2 hours postoperatively. Blood glucose, hemodynamic, and oxygenation-ventilation variables, and postoperative outcomes were also measured. RESULTS: Norepinephrine and epinephrine levels remained unchanged over time in the deep group, but norepinephrine levels significantly increased in the light group at 2 h after surgery than at baseline (P = 0.007 and 0.004, respectively). Temporal changes in norepinephrine, but not in epinephrine, were significantly different between the two groups (P = 0.036). Plasma glucose levels in the light group increased with time and were significantly higher than in the deep group at the end of surgery (P = 0.002). CONCLUSIONS: A deep level of anesthesia achieved using high propofol infusion rates during lung surgery provided lower perioperative norepinephrine and glucose responses than light level of anesthesia during the early postoperative period but failed to affect immediate postoperative outcomes.

Intervenção fisioterapêutica pré-operatória para pacientes submetidos à ressecção pulmonar por câncer: revisão sistemática / Preoperative physiotherapeutic intervention for patients undergo resection for lung cancer: systematic review

INTRODUÇÃO: A Fisioterapia tem sido defendida como um componente importante na prevenção e no tratamento de complicações pulmonares pós-operatórias, sendo utilizada nas fases pré e pós-operatória de ressecções pulmonares. A efetividade e a segurança da fisioterapia pré-operatória em pacientes que serão submetidos a cirurgias de ressecção pulmonar por câncer precisam ser avaliadas. MATERIAIS E MÉTODOS: Revisão sistemática de ensaios clínicos randomizados com metodologia Cochrane. A busca eletrônica foi realizada nas bases de dados Cochrane Central Register of Controlled Trials (CENTRAL); PEDro; MEDLINE; EMBASE; CINAHL; e LILACS. Realizamos também uma busca por estudos em andamento e/ou não publicados, através da Current Controlled Trials Database. Além disso, realizamos uma busca adicional na lista de referências de todos os estudos incluídos e contato com os autores, quando necessário. RESULTADOS: Vinte e oito estudos foram considerados potencialmente relevantes; destes, 26 foram excluídos. Dois ensaios clínicos randomizados preencheram os critérios de inclusão desta revisão. Um estudo comparou a ventilação mecânica não invasiva (BILEVEL) associada ao tratamento padrão versus tratamento padrão sendo atribuído de forma única; e o outro estudo comparou o treinamento muscular inspiratório e a espirometria de incentivo a nenhum tratamento. Um único desfecho foi comum entre os estudos, mas não foi possível realizar uma metanálise devida à insuficiência de informações. CONCLUSÕES: Não há evidência suficiente na literatura para se afirmar que a intervenção fisioterapêutica pré-operatória seja efetiva e segura para pacientes que serão submetidos à ressecção pulmonar por câncer.

INTRODUCTION: The physiotherapy has been advocated as an important component in the treatment and prevention of postoperative pulmonary complications, being used in both pre and postoperative periods of lung resection surgery. The objective of this study was to assess the efficacy and safety of preoperative physiotherapy for patients who will undergo resection surgery for lung cancer. MATERIALS AND METHODS: Systematic review of randomized clinical trials carried out in accordance with the Cochrane metodology. The electronic search was performed in Cochrane Library, PEDro, MEDLINE, EMBASE, CINAHL, LILACS. We also searched for both non-published and on-going studies in the Current Controlled Trials database. In addition, a manual search in the references of all relevant studies was performed, and the authors were contacted for additional non-published data. RESULTS: Twenty-eight papers were considered potentially relevant; among them, 26 were excluded. Two randomized controlled trials met the inclusion criteria. One study compared non invasive ventilation (BILEVEL) associated to standard treatment with standard treatment alone; and other study compared inspiratory muscle training and incentive spirometry with no training. There was just one common outcome between the studies, but was not possible to perform the meta-analysis due to missing data. CONCLUSION: There is no sufficient evidence to state that the preoperative physiotherapeutic intervention has efficacy and safety for patients who will undergo resection surgery for lung cancer.

Los tipos de lesiones radiológicas más frecuentes fueron: Lesiones cavitadas localizadas 14 (56 por ciento) y lesiones con destrucción pulmonar 06 (24 por ciento). CONCLUSION: El tratamiento quirúrgico de resección pulmonar asociado con la quimioterapia antituberculosa para pacientes multidrogorresistentes proporciona una evolución favorable comparada con la administración de solamente la terapia farmacológica.

A Case of Primary Endobronchial Neurilemmoma Without Intraspinal Extension / 영남의대학술지

Neurilemmoma is a benign and slowly growing neurogenic tumor. Intrathoracic neurilemmoma often develops in the chest wall and posterior mediastinum, but endobronchial neurilemmoma is extremely rare. The diagnosis of endobronchial neurilemmoma with preoperative imaging findings is challenging and is usually made via postoperative pathological examination. These authors encountered a case of primary endobronchial neurilemmoma in a 52-year-old woman who had no symptoms. A 3.0 x 2.6 cm mass in the right lower lobe projecting into the mediobasal segmental bronchus was shown in the results of the contrast-enhanced computed tomography (CT) and magnetic resonance imaging (MRI) of the chest. Benign neurilemmoma was confirmed via bronchoscopic biopsy, and surgical resection (sleeve bronchial excision and end-to-end anastomosis) was performed.

Respiratory Review of 2012: Bronchoscopic Innovations and Advances / 결핵및호흡기질환

Recent advances in bronchoscopy have led to changes in clinical diagnostics and therapeutics in pulmonary medicine. In diagnostic bronchoscopy, there have also been new developments in endobronchial ultrasound technology which may be incorporated into clinical practice in the near future. Functional bronchoscopy, which evaluates information such as airway pressure, airflow, or gas exchange, suggests promising clinical advances in the near future. In therapeutic bronchoscopy, bronchoscopic volume reduction is a novel approach for the treatment of severe emphysema. In this review, seven recently published articles representing current advances in bronchoscopy are summarized and discussed.

Pericardial tamponade after left posterolateral thoracotomy for left upper lobectomy for pulmonary aspergilloma.

Pericardial tamponade limits diastolic filling of the heart; therefore, a high venous pressure is required to fill the ventricle. In presence of cardiac tamponade, therapeutic agents and manoeuvres that results in venodilation or vasodilation can severely compromise diastolic filling of the heart and might result in rapid cardiac decompensation. Equalization of central venous pressure and pulmonary artery diastolic pressure or equalization of pressures in all four chambers during diastole confirms cardiac tamponade. Transthoracic echocardiography can detect the site of tamponade and assist in pericardiocentesis. We describe acute pericardial tamponade in a young man who underwent left posterolateral thoracotomy for left upper lobectomy. Intraoperatively, mobilization of the left upper lobe was frequently associated with hypotension. Postoperatively, the patient suffered two more episodes of hypotension. The episodes of hypotension were attributed to surgical manipulation and epidural blockade. Hemodynamics normalized after discontinuing epidural infusion, volume resuscitation and lobectomy. On third postoperative day, the patient developed cardiovascular collapse; arterial blood pressure and central venous pressure were 70/50 and 12 mmHg. Investigations showed haziness of left lung, and severe respiratory acidosis. On opening of the left thoracotomy wound, pericardial tamponade was diagnosed. A pericardial window was created and tamponade was released with that the hemodynamics normalized. Episodes of unexplained hypotension after left upper lobectomy suggest a cardiac etiology and acute pericardial tamponade is a possibility which should be released immediately otherwise it can result in fatal outcome.

Post major lung resection cardiac arrhythmias

To describe the possible postoperative cardiac arrhythmias after major lung resection surgery performed for lung malignancies. This descriptive study was conducted from January 2007 to October 2009 at the Thoracic Surgery Division of the Royal Medical Services in Amman-Jordan. Forty-eight patients were included in this study. Patients with pre existing cardiac diseases were excluded. All the patients underwent different types of major lung resection surgery for primary and secondary lung malignancies. Postoperative cardiac arrhythmias after different types of lung resection surgery were documented and described. Simple descriptive statistics were used. The sample included 35 males [72.9%] and 13 females [27.1%]. Age ranged between 21 to 82 years [mean 56.6 +/- 14.9]. Left sided surgery was performed in 21 patients [43.7%], while right sided resections were performed in 27 patients [56.3%]. Lobectomy was the most commonly performed operation which was carried out in 27 patients [56.3%], followed by pneumonectomy which was performed in 14 patients [29.2%]. Post operative cardiac arrhythmias occurred among 19 patients [39.6%]. Atrial fibrillation was the most common reported arrhythmia which occurred in 15 patients [31.2%], followed by supra ventricular tachycardia in 2 patients [4.2%], and 2 patients developed atrial flutter [4.2%]. Cardiac arrhythmias were observed to be more common after lobectomy or pneumonectomy, in old male patients, and during the first 48 hours post lung resection. Post major lung resection cardiac arrhythmias are common. Preoperative evaluation and postoperative cardiac monitoring are mandatory in these patients even among those without pre existing cardiac diseases

Research on fast track surgery application in lung cancer surgery / 中国肺癌杂志

<p><b>BACKGROUND AND OBJECTIVE</b>Fast track surgery (FTS) is a systematical method to accelerate the recovery of surgical patients by reducing the physical and mental trauma stress of them. The research is to investigate the feasibility of FTS application in lung cancer surgery.</p><p><b>METHODS</b>A total of 80 cases of lung cancer patients with single leaf lobotomy resection were randomized into two groups. While the experimental group was treated with the conception of FTS, and the control group was treated with the traditional methods. The incident rate of post-operation pain degrees, telecasts, pleural effusion, the post-operation time stay in hospital time and the total cost during hospitalization in two groups were compared respectively.</p><p><b>RESULTS</b>In FTS group: the VAS score of post-operation pain at 1 h, 6 h, 12 h, 24 h and 48 h all significantly decreased compared to the traditional therapy group. The incidence rate of telecast was 10.53%. The incidence rate of pleural effusion was 26.31%. The length of stay after operation was (4 +/- 1) d and the total cost was RMB 15 600 +/- 7 600. In the control group, the above values were 77.78%, 33.33%, 22.22%, (9 +/- 1) d, RMB 23 600 +/- 5 400, respectively. The post operation pain (VAS method) of FTS group was remarkablely below the control group. There has significant difference of the incident rate of telecasts, stay time in hospital and the total cast in two groups (P < 0.05). No significant difference was observed in the incident rate ofpleural effusion.</p><p><b>CONCLUSION</b>The new methods of FTS can apparently accelerates recovery after lung cancer resection, reduces complications, shorten timestay in hospital and cut down the total cost.</p>

Early surgical treatment of bronchopleural fistula after pneumonectomy / 南方医科大学学报

<p><b>OBJECTIVE</b>To investigate the method of early surgical treatment of bronchopleural fistula after pneumonectomy.</p><p><b>METHODS</b>Twelve patients (9 males and 3 females with a mean age of 58.6-/+5.7 years) with bronchopleural fistula after pneumonectomy received a reoperation within 72 h after a definite diagnosis. Empyema was found in none of the 12 cases. Fistula occurred within 4 to 17 days (8 days in average) after the operation. The fistula of the residual main bronchus was resected, and the thoracic cavity was asepticized by flushing.</p><p><b>RESULTS</b>Ten patients were discharged with complete healing. One patient was discharged following open drainage with daily change of the wound dress. One patient died due to multiple organ failure. The hospital stay of the patients ranged from 18 to 49 days (31 days in average) after the reoperation.</p><p><b>CONCLUSION</b>Bronchopleural fistula after pneumonectomy, in case that empyema and multiple organ failure do not occur, can be healed by closing the fistula with the stapling device in early stage. Flushing the thoracic cavity is also necessary after the reoperation.</p>
