RESUMO

Resumen El Streptococcus viridans es conocido más comúnmente como agente infeccioso en las endocarditis, sin embargo, poco se conoce sobre su potencial infeccioso en otros órganos o sistemas, donde ha demostrado una elevada mortalidad. El reconocimiento del Streptococcus viridans como agente productor de abscesos en otras localizaciones como a nivel hepático o pulmonar, permitirá un diagnóstico oportuno mediante los distintos métodos de imagen, reduciendo las graves consecuencias para el paciente y los tiempos de hospitalización. Se presenta el caso de un paciente del sexo masculino de 33 años de edad sin antecedentes crónico degenerativos, que inició con sintomatología 7 meses previos a su ingreso, con fiebre intermitente, fatiga, astenia, anorexia y pérdida de peso. A la exploración física presentó dolor a la palpación media y profunda en hipocondrio derecho, en el panel de laboratorios presentó llamativa neutrofilia, en la tomografía de tórax y abdomen se mostró lesión cavernomatosa en pulmón y quistes complicados hepáticos, a los cuales se les realizó drenaje percutáneo guiado por ultrasonido, con envío de muestras a cultivo con resultado positivo para Streptococcus viridans, lo que permitió brindar el tratamiento dirigido al paciente, y que remitiera la enfermedad.

Abstract Streptococcus viridans is more commonly known as an infectious agent in endocarditis, however, little is known about its infectious potential in other organs or systems, where it has shown high mortality. The recognition of Streptococcus viridans as an abscess-producing agent in other locations, such as the liver or lungs, will allow timely diagnosis using different imaging methods, reducing serious consequences for the patient and hospitalization times. We present the case of a 33-year-old male patient with no chronic degenerative history, who started symptoms 7 months prior to admission, with intermittent fever, fatigue, asthenia, anorexia and weight loss, on physical examination he presented pain at the medium and deep palpation in the right hypochondrium, in the laboratory panel I present striking neutrophilia, in the tomography of the thorax and abdomen a cavernous lesion in the lung and complicated hepatic cysts are shown, to which percutaneous drainage guided by ultrasound is performed, with sending of cultured samples with a positive result for Streptococcus viridans. Thus, allowing treatment to be provided to the patient, thereby achieving remission of the disease.

RESUMO

Lung abscess is a rare entity in pediatric age, but it generates significant morbidity. Even less frequent is the presence of this with spontaneous drainage to the skin, generating an abscess in the chest wall, reason for consultation, of the present clinical case. Subsequently, the presence of lung abscess with extension to the chest wall without pleural involvement was documented by imaging studies, an extremely rare and unusual entity, with only one case described in the world literature within our reach and in an adult patient.

El absceso pulmonar es una entidad infrecuente en la edad pediátrica, pero que genera una morbilidad importante. Aún menos frecuente es la presencia de este con drenaje espontáneo a piel, generando un absceso en pared torácica, motivo de consulta, del presente caso clínico. Posteriormente y por estudios imagenológicos se documentó la presencia de absceso pulmonar con extensión a pared torácica sin afectación pleural, una entidad extremadamente rara e inusual, con un solo caso descrito en la literatura mundial a nuestro alcance y en un paciente adulto.

RESUMO

Pulmonary artery aneurysm is a disorder of varying etiology and should be diagnosed early for appropriate interventions. A 45-year-old man was hospitalized for chest pain, dyspnea, cough, chills, diarrhea, and vomiting, which had started 3 weeks before admission. Physical examination indicated a reduced vesicular murmur in the right hemithorax. A chest x-ray performed indicated a pneumothorax and pulmonary abscess in the right hemithorax. Thoracostomy released abundant purulent and fetid fluid. Direct examination of the pleural fluid using saline revealed structures similar to Trichomonas. Non-contrast chest computed tomography revealed right pneumothorax along with an irregular cavitation located at the pleuropulmonary interface of the posterior margin of the right lower lobe. A pleurostomy was performed. On the second postoperative day, the patient suffered a sudden major hemorrhage through the surgical wound and died on the way to the operating room. The autopsy revealed an abscess and ruptured aneurysm of the lower lobar artery in the lower right lung. Microscopic examination revealed extensive liquefactive necrosis associated with purulent inflammation and the presence of filamentous fungi and spores. This case can be characterized as a severe disorder that requires early diagnosis to achieve a good therapeutic response and to avoid fatal outcomes.

RESUMO

ABSTRACT Objective: The history of Anatomical Pathology in the state of Paraná, in southern Brazil, is closely linked with the foundation of the Universidade Federal do Paraná (UFPR). This study identified the first central nervous system (CNS) clinical autopsy performed by the Department of Anatomical Pathology of the UFPR. Methods: This study reviewed the autopsy report archives of the Hospital de Clínicas-UFPR from 1951 onward. The clinical anatomy interpretations of the autopsy report and possible etiologic agents were discussed. Result: The first adult clinical autopsy with CNS study was performed on April 23, 1952 on a 45-year-old man with lobar pneumonia with abscesses complicated by bacterial meningitis. Conclusion: This case was the first CNS clinical autopsy performed in the state of Paraná and, possibly, in southern Brazil. The death was due to an infectious disease, which was the main cause of death in Brazil in the 1950s.

RESUMO

Las mielopatías constituyen un conjunto heterogéneo de procesos patológicos que directa o indirectamente afectan a la médula espinal. Son poco frecuentes y pueden ser producidos por variadas causas y vías de afectación, que conllevan a grandes secuelas y elevada discapacidad. Se describe un caso de mielopatía aguda compresiva desencadenada por un absceso pulmonar como causa y mecanismo de producción inusual. Hombre de 48 años, con antecedentes de salud y cuadro clínico de inicio brusco de paraparesia fláccida e hiporreflexia osteotendinosa de miembros inferiores asimétrica, con predominio derecho, nivel sensitivo dorsal a nivel de D4 y dolor a la percusión en procesos espinosos dorsales en D3-D6. Los estudios sanguíneos, inmunológicos y de líquido cefalorraquídeo resultaron irrelevantes, excepto muestra de signos indirectos de infección. La radiografía de tórax mostró la presencia del absceso pulmonar primario derecho y la afectación medular se corroboró a través de la realización de la resonancia magnética medular dorsal. Presentó pobre respuesta ante los esteroides parenteral, hasta que se inició la terapia antibiótica, de forma paulatina y con apoyo rehabilitador. Transcurridos tres meses se investigaron y fueron descartadas otras etiologías no compresivas. Las mielopatías agudas representan un grupo heterogéneo de trastornos con distintas etiologías y mecanismos de producción, a través de su estudio se evidenció como causa un absceso pulmonar con afectación medular, por lo que debe ser considerado en la extensa lista de diagnósticos diferenciales (AU).

Myelopathies are a heterogeneous group of pathological processes that directly or indirectly affect the spinal cord. They are rare and can be produced by different causes and affectation pathways leading to major consequences and high disability. A case of acute compressive myelopathy triggered by a lung abscess as unusual cause and production mechanism is described. It is the case of a man, aged 48 years, with a clinical history and symptoms of acute onset of flaccid paraparesis and asymmetric osteotendinous hyporeflexia of lower limbs, with right predominance, dorsal sensitive level at D4, and pain at percussion in D3-D6 dorsal spinal processes. Blood, immune and cerebrospinal fluid (CSF) studies were irrelevant, but showing indirect signs of infection. Chest radiography showed the presence of the right primary lung abscess and spinal cord involvement was confirmed by performing dorsal medullar magnetic resonance (MRI). The patient had poor response to parenteral steroids until antibiotic therapy began, gradually and with rehabilitation support. After three months, other non-comprehensive etiologies were studied and ruled out. Acute myelopathies represent a heterogeneous group of disorders with different etiologies and production mechanisms. The study evidenced a lung abscess with spinal cord involvement as a cause, so it should be considered in the extensive list of differential diagnoses (AU).

RESUMO

Introducción: Las neumonías necrosantes (NN) con empiema son una enfermedad grave y un desafío multidisciplinario. El objetivo de este estudio es realizar una caracterización epidemiológica y, en forma secundaria, analizar su tratamiento y evolución. Presentación de casos: Se realizó un estudio retrospectivo de una serie de casos consecutivos con NN con empiema que se presentaron en el Hospital Padre Hurtado. Siete (77,8%) eran de sexo masculino. La mediana de edad fue de 53 (rango 21-73) años. El 44% presentaban comorbilidades (diabetes, HTA o enfermedades neurológicas). El 44% presentaban abuso de drogas y 3 estaban en un estado de desnutrición severa. Manejo y evolución: La mediana de tiempo de hospitalización fue de 41 (rango 16-129) días. En 4 pacientes el germen aislado fue un Enterococcus faecalis. Complicaciones torácicas ocurrieron en el 33,3% de los pacientes. Un paciente requirió una lobectomía, un paciente una fenestración y otro paciente falleció. Discusión: Las NN con empiemas son raras. Sin embargo, frente a la asociación de diabetes, desnutrición y abuso de drogas continuaremos viendo estos casos de difícil manejo con elevada morbimortalidad.

Introduction: Necrotizing pneumonia complicated with empyema is a life-threatening condition that challenges multidisciplinary teams. The aim of this study is to perform an epidemiological characterization of these patients, and secondly, analyse their treatment and outcomes. Case presentation: A retrospective analysis of a series of consecutive patients experiencing necrotizing pneumonia with empyema who presented at Hospital Padre Hurtado. Seven (77.8%) were male. The median age was 53 (range 21-73) years. 44% presented with comorbidities (diabetes, high blood pressure, and neurological diseases). 44% presented drug abuse consumption and three (33.3%) were in a state of severe malnutrition. Management and outcome: The median time of hospitalization was 41 (range 16-129) days. Thoracotomies were performed in eight (83.2%) of the patients. In four patients, the isolated bacteria's were Enterococcus faecalis. Thoracic complications occurred in three (33.3%) patients. One patient required a lobectomy, one patient a fenestration and one (11.1%) patient died. Discussion: Necrotizing pneumonias complicated with empyema are rare, however, if there is an association with drug abuse, diabetes and malnutrition, we will continue to see such challenging cases with high morbidity and mortality.

RESUMO

Fundamento: A pesar, de que hay reportes de casos en la literatura internacional, que asocian la enfermedad periodontal con enfermedades respiratorias y medidas para la prevención de la enfermedad periodontal inflamatoria, sino se establece un adecuado manejo de esta última, puede evolucionar con una complicación sistémica como es el absceso pulmonar. Objetivo: Ilustrar cómo la enfermedad periodontal inflamatoria puede asociarse a un absceso pulmonar como complicación sistémica en su evolución. Presentación del caso: Se presenta una paciente femenina con antecedentes de absceso periodontal y enfermedad periodontal crónica, los cuales constituyeron las únicas causas demostradas del desarrollo de un absceso pulmonar, tras la aplicación del método clínico. Conclusiones: La enfermedad periodontal inflamatoria puede evolucionar hacia la remisión si se adoptan las medidas protocolizadas para su tratamiento, sin embargo, siempre que esa enfermedad siga su curso natural o no se maneje adecuadamente puede evolucionar a complicaciones sistémicas como lo es el absceso pulmonar.

Background: Although there are in the international literature report of cases, which associate the peridental disease to respiratory diseases and measurements to the prevention of the peridental inflammatory disease, if there is not established an adequate usage of the last one, it can emerge with a systemic complication like lung abscess. Objective: To show how the peridental inflammatory disease can be associated to a lung abscess like a systemic complication in its evolution Case Presentation: A female patience is presented with antecedents of peridental abscess and chronic peridental disease, which were the unique causes demonstrated in the development of a lung abscess, after the application of the clinic method Conclusions: The peridental inflammatory disease can emerge towards the remission if some protocolic precautions are adopted for its treatment; nevertheless whenever the disease follows its natural course or it is not properly managed it can emerge to systemic complications like, it is the lung abscess.

RESUMO

Fístula bronquiobiliar (FBB) é uma afecção rara, de alta morbidade e mortalidade, decorrente da comunicação anormal entre a árvore brônquica e a via biliar, sendo a bilioptise um sinal clínico patognomônico. Normalmente está associada a doenças hepatobiliares, mas principalmente ao trauma e complicações de cirurgias hepatobiliares. Devido à gravidade e à complexidade, associadas à baixa incidência, seu manejo é desafiador, não havendo um consenso na literatura. Este trabalho identifica os métodos diagnósticos e terapêuticos mais utilizados, e propõe um fluxograma do manejo da FBB com intuito de auxiliar a conduta de novos casos.

Bronchobiliary fistula is a rare clinical finding, with a high morbidity and mortality rate, characterized by abnormal communication between the biliary tract and the bronchial tree, having bilioptysis as a pathognomonic sign. It is usually associated to hepatobiliary diseases, but mostly related to trauma and as a complication of hepatobiliary surgery. Due to the low incidence, complexity and gravity, its management is a challenge, and little consensus on its diagnosis and treatment exists. We identified the most used diagnostic and therapeutic procedures, and propose a flowchart that could assist in the management of news cases.

RESUMO

Introducción: el desarrollo de los antimicrobianos provocó que el drenaje externo dejara de realizarse en pacientes con absceso de pulmón, en quienes la resección pulmonar es la opción ante el fracaso médico. En los últimos años, la neumostomía ha resurgido por la necesidad de asistir a enfermos con un marcado deterioro físico que impide una intervención quirúrgica resectiva. Objetivo: caracterizar a los pacientes con supuración pulmonar tratados quirúrgicamente mediante drenaje percutáneo externo y neumostomía con sonda de balón (método de Monaldi) practicados con anestesia local. Métodos: se realizó un estudio descriptivo longitudinal retrospectivo en el período de 1995 a 2012 en el Hospital Universitario Comandante Manuel Fajardo. El universo estuvo conformado por 8 pacientes a los que se les practicó el método de Monaldi. En todos los casos se utilizaron sondas de goma de balón de 24 unidades F, de tres ramas. Resultados: cuatro pacientes padecían de absceso del pulmón y el resto de bullas enfisematosas voluminosas infectadas. Todos los casos tuvieron resolución de la colección infectada en un período inferior a las 2 semanas, y no hubo complicaciones ni mortalidad quirúrgica. Conclusiones: el drenaje percutáneo con anestesia local utilizando sondas de balón es un instrumento adecuado para el tratamiento de colecciones pulmonares en enfermos con deterioro físico por el cuadro infeccioso. Con él se logra la resolución de la lesión pulmonar, y es efectivo tanto en los abscesos pulmonares como en las bullas enfisematosas infectadas(AU)

Introduction: with the advent of the antibiotic therapy, external drainage ceased to be performed in lung abscess patients for whom the pulmonary resection is the choice. In the last few years, pneumostomy has reemerged due to the need of giving assistance to patients with remarkable physically deterioration that hinders resective surgery. Objectives: to characterize patients with pulmonary suppuration and surgically treated by means of external percutaneous drainage with balloon catheter pneumostomy (Monaldi method) using local anesthesia. Methods: retrospective, descriptive and longitudinal study of eight patients, who underwent Monaldi method-based surgery, conducted from 1995 through 2012 at Manuel Fajardo university hospital. Three branch twenty-four F unit balloon rubber catheters were used in all these cases. Results: out of the eight, four had been diagnosed with lung abscess and the other four had large septic emphysematous sacs. The infected collection was eliminated in all these patients in less than 2 weeks with no complication and no surgical death. Conclusion: The percutaneous drainage with local anesthesia using balloon catheter as an instrument was adequate and useful in the treatment of septic lung collections in patients with very poor physical condition. This method manages to eliminate the pulmonary lesion and is good for both pulmonary abscesses and infected emphysematous sacs(AU)

RESUMO

El absceso hepático piógeno producido por klebsiella pneumoniae es relativamente raro y puede complicarse con lesiones sépticas a distancia. Esto se relaciona con características propias del germen que incluye el genotipo K1, resistencia a la fagocitosis y la presencia de gen mag-A. Tales metástasis sépticas contemplan absceso pulmonar, meningitis, endocarditis bacteriana y, muy especialmente, endoftalmitis. Esta última ocurre con mayor frecuencia en pacientes diabéticos, y puede causar ceguera. Se reporta caso de absceso hepático por K. pneumoniae asociado a absceso pulmonar y endoftalmitis, y se revisa epidemiología, fisiopatologia, diagnóstico y tratamiento de la entidad...

RESUMEN: Arch Med Interna 2013 - 35(1):09-14 El absceso de pulmón definido como una lesión necrosada y cavitada del parénquima pulmonar de origen infeccioso, son de etiología polimicrobiana, incluyendo en el 95% de los casos gérmenes anaerobios. La patogenia fundamental son las aspiraciones, y se reconocen como factores favorecedores todos aquellas situaciones clínicas que favorecen éstas. El diagnóstico reside en la confirmación imagenológica de la imagen cavitada, estando los estudios endoscópicos destinados al apoyo bacteriológico o a descartar patologías asociadas fundamentalmente. El tratamiento es médico, con dos pilares: el drenaje postural y la antibioticoterapia. Determinadas situaciones clínicas y/o complicaciones tienen indicaciones quirúrgicas. El trabajo consiste en una revisión sistemática de todos los casos de absceso de pulmón de los últimos 3 años en un servicio de clínica médica. Con una incidencia de 17 casos, se presentan los principales aspectos epidemiológicos clínicos y paraclínicos de éstos.

ABSTRACT: Arch Med Interna 2013 - 35(1):09-14 Lung abscesses -defined as a necrosed and cavitated lesions of the lung parenchyma resulting from infection- are polymicrobial, and in 95% of the cases they include anaerobic organisms. The main pathway of infection is through aspirations, and all the clinical conditions that favor aspiration are recognized as predisposing factors. The diagnosis lies on the imaging confirmation of a cavitated image; endoscopy plays a role as a support to bacteriology, or primarily to rule out co-morbidities. Therapy is medical, and based on two pillars: postural drain and antibiotic therapy. There are certain clinical situations and/or complications that require surgery. The paper consists of a systematic review of all the cases of lung abscess in a medical ward in the last three years. With an incidence of 17 cases, the paper depicts their key clinical and laboratory epidemiologic features.

RESUMO

O abscesso pulmonar é uma lesão necrótica geralmente devida a germes piogênicos. A fisioterapia respiratória (FR) é indicada, porém há poucos relatos na literatura, não havendo consenso quanto ao uso e às técnicas de FR para esse caso. O objetivo deste estudo de dois casos foi verificar a segurança e efetividade da FR no tratamento do abcesso pulmonar. O caso 1 foi um paciente de 30 anos, internado; a terapia consistiu em posicioná-lo em Trendelenburg semi-lateral direito para ventral por 30 minutos, três vezes ao dia, com saída de grande quantidade de secreção. Após 5 dias, o radiograma de tórax demonstrou redução de 90% do nível hidroaéreo, verificando-se o esvaziamento completo do abscesso após 14 dias de internação. O caso 2 foi uma paciente de 28 anos igualmente com diagnóstico de abscesso pulmonar, também tratada com drenagem postural, nos mesmos posicionamento e freqüência que o caso 1, sendo drenada grande quantidade de secreção amarelada e fluida. Após 7 dias de tratamento evidenciou-se redução importante do nível líquido do abscesso pulmonar. Conclui-se que a drenagem postural isoladamente é uma técnica de fisioterapia efetiva e segura no tratamento do abcesso pulmonar.

Lung abscess is a necrotic lesion mostly caused by pyogenic germs. Chest physical therapy (CPT) is indicated, but there are few studies available and no consensus on CPT use and techniques for theses cases. The purpose of this study was to assess safety and effectiveness of postural drainage in treating lung abscess in two cases. Patient 1, male, 30 years old, was laid in Trendelenburg, in semi-lateral to ventral decubitus for 30 minutes, three times a day. After five days of therapy, X-ray showed a 90% decrease of sputum, and on the 14th day full drainage was achieved. Case 2 was a female patient, 28 years old, treated at the same position and frequency as case 1. After seven days of therapy, exams showed a great decrease of pus from the abscess. It may thus be said that postural drainage alone is a safe and effective chest physical therapy technique for treating lung abscesses.

RESUMO

OBJETIVO: Descrever os resultados do tratamento cirúrgico de crianças com pneumonia necrosante. MÉTODOS: Análise retrospectiva dos prontuários de 20 crianças diagnosticadas com pneumonia necrosante e submetidas ao tratamento cirúrgico nos serviços de cirurgia torácica de dois hospitais na cidade de Manaus (AM) entre março de 1997 e setembro de 2008. Dados referentes a idade, sexo, agente etiológico, motivos da indicação cirúrgica, tipo de ressecção cirúrgica realizada e complicações pós-operatórias foram compilados. RESULTADOS: Dos 20 pacientes analisados, 12 (60 por cento) eram do sexo feminino. A média de idade dos pacientes foi de 30 meses. Os agentes etiológicos mais encontrados foram Staphylococcus aureus, em 5 pacientes (25 por cento), e Klebsiella sp., em 2 (10 por cento). Os motivos de indicação cirúrgica foram sepse, em 16 pacientes (80 por cento), e fístula broncopleural, em 4 (20 por cento). Os tipos de procedimentos cirúrgicos realizados foram lobectomia, em 12 pacientes (60 por cento), segmentectomia, em 7 (35 por cento), e bilobectomia, em 1 (5 por cento). Além desses procedimentos, 8 pacientes (40 por cento) foram submetidos à descorticação pulmonar. As complicações pós-operatórias foram as seguintes: fístula broncopleural, em 4 pacientes (20 por cento); empiema, em 1 (5 por cento); pneumatocele, em 1 (5 por cento); e flebite em membro superior esquerdo, em 1 (5 por cento). Quatro pacientes (20 por cento) morreram. CONCLUSÕES: Pacientes com evidências de necrose pulmonar devem ser considerados para a ressecção cirúrgica, que está indicada em casos graves de sepse, fístula broncopleural de alto débito ou insuficiência respiratória aguda que não respondem ao tratamento clínico.

OBJECTIVE: To describe the results of the surgical treatment of children with necrotizing pneumonia. METHODS: A retrospective analysis of the medical charts of 20 children diagnosed with necrotizing pneumonia and submitted to surgical treatment between March of 1997 and September of 2008 in the thoracic surgery departments of two hospitals in the city of Manaus, Brazil. We compiled data regarding age, gender, etiologic agent, indications for surgery, type of surgical resection performed, and postoperative complications. RESULTS: The mean age of the patients was 30 months. Of the 20 patients studied, 12 (60 percent) were female. The most common etiologic agents were Staphylococcus aureus, in 5 patients (25 percent), and Klebsiella sp., in 2 (10 percent). The indications for surgery were sepsis, in 16 patients (80 percent), and bronchopleural fistula, in 4 (20 percent). The types of surgical procedures performed were lobectomy, in 12 patients (60 percent), segmentectomy, in 7 (35 percent), and bilobectomy, in 1 (5 percent). There were 8 patients (40 percent) who also underwent decortication. The postoperative complications were as follows: bronchopleural fistula, in 4 patients (20 percent); empyema, in 1 (5 percent); pneumatocele, in 1 (5 percent); and phlebitis of the left arm, in 1 (5 percent). Four (20 percent) of the patients died. CONCLUSIONS: Surgical resection should be considered in patients with evidence of pulmonary necrosis. Resection is indicated in cases of severe sepsis, high output bronchopleural fistula, or acute respiratory failure that are refractory to clinical treatment.

RESUMO

A síndrome de Lemierre é caracterizada pela infecção aguda da orofaringe, complicada por trombose venosa jugular interna secundária à tromboflebite séptica, e por infecções metastáticas a vários órgãos distantes-mais freqüentemente os pulmões. Relatamos um caso de síndrome de Lemierre em uma mulher de 56 anos que se apresentou com massa cervical à direita e febre. Trombose venosa jugular interna foi demonstrada na ecografia. A tomografia computadorizada de tórax revelou múltiplas opacidades em ambos os pulmões. Uma biópsia pulmonar cirúrgica foi realizada por suspeita de metástases pulmonares. O exame anatomopatológico revelou êmbolos sépticos em parênquima pulmonar. Retrospectivamente, a paciente relatou história de faringite duas semanas antes da hospitalização. Após o diagnóstico, foi tratada com antibióticos de amplo espectro (cefuroxima por 7 dias e azitromicina por 5 dias e, posteriormente, devido à persistência de febre, cefepime por 7 dias). A tomografia computadorizada de tórax, realizada um mês após, mostrou resolução das opacidades.

Lemierre's syndrome is characterized by acute oropharyngeal infection, complicated by internal jugular venous thrombosis secondary to septic thrombophlebitis, and by metastatic infections in various distant organs-most commonly in the lungs. We report a case of Lemierre's syndrome in a 56-year-old female who presented with right-sided neck mass and fever. Right internal jugular venous thrombosis was demonstrated on an ultrasound. A computed tomography scan of the chest revealed multiple opacities throughout both lungs. An open surgical biopsy was performed due to suspicion of pulmonary metastases. Anatomopathological examination revealed septic emboli in lung parenchyma. Retrospectively, the patient reported a history of pharyngitis two weeks prior to hospitalization. After the diagnosis had been made, the patient was treated with broad-spectrum antibiotics (cefuroxime for 7 days and azithromycin for 5 days; subsequently, because fever persisted, cefepime for 7 days). One month later, a computed tomography scan of the chest revealed resolution of the opacities.

RESUMO

A fístula gastrobrônquica é uma condição rara como complicação decorrente de cirurgia da obesidade. O seu manejo exige a participação ativa de um pneumologista, o qual deve conhecer alguns aspectos dos principais tipos de cirurgia bariátrica. Neste relato, descrevemos dois casos de pacientes que apresentaram abscessos subfrênico e pulmonar recidivantes secundários a fístula no ângulo de His durante 19,5 meses, em média. Após o insucesso das relaparotomias, a cura foi obtida por meio da antibioticoterapia e, principalmente, por meio da estenostomia e da dilatação endoscópica, além do uso de clipes e cola de fibrina na fístula. Estas complicações pulmonares não devem ser tratadas isoladamente sem uma avaliação gastrintestinal pois isso pode resultar em piora do quadro respiratório, dificultando o manejo anestesiológico durante procedimentos endoscópicos.

Gastrobronchial fistula is a rare condition as a complication following bariatric surgery. The management of this condition requires the active participation of a pulmonologist, who should be familiar with aspects of the main types of bariatric surgery. Herein, we report the cases of two patients who presented recurrent subphrenic and lung abscess secondary to fistula at the angle of His for an average of 19.5 months. After relaparotomy was unsuccessful, cure was achieved by antibiotic therapy and, more importantly, by stenostomy and endoscopic dilatation, together with the use of clips and fibrin glue in the fistula. These pulmonary complications should not be treated in isolation without a gastrointestinal evaluation since this can result in worsening of the respiratory condition, thus making anesthetic management difficult during endoscopic procedures.
