Tratamiento percutáneo de la hemoptisis. Anatomía, fisiopatología y metodología / Percutaneous treatment of hemoptysis. Anatomy, physiopathology and methodology

Resumen Se presentan los resultados de 105 pacientes con hemoptisis amenazante tratados mediante embolización arterial por cateterismo percutáneo por vía arterial sistémica y/o arterial pulmonar. Se describe la técnica del procedimiento y los hallazgos angiográficos. Se muestra la utilidad de la fibrobroncoscopía y de la radiografía de tórax para identificar la zona sangrante como diagnóstico previo al procedimiento. Entre mayo 2000 y septiembre 2015 se admitieron en el Servicio de Hemodinamia 105 pacientes con diagnóstico de hemoptisis amenazante, 76 masculinos (72.4%); edad media: 41 (±18.65 DS) años. El 93% (98/105) fue tratado con éxito. En el 90% (88/98) se efectuó embolización por arterias bronquiales y/o no bronquiales sistémicas y en el 10% (10/98) por vía arterial pulmonar. Cuando la afección era bilateral la angiografía sola no posibilitó identificar el sitio de sangrado. Al 60% (63/98) se le hizo fibrobroncoscopía flexible y se pudo ubicar el pulmón sangrante en el 84% (56/63). Cuando la afección era unilateral, la radiografía de tórax previa al procedimiento facilitó la ubicación del área de sangrado en el 47%. No se observaron complicaciones graves ni muertes vinculadas al procedimiento. El tratamiento de la hemoptisis masiva por vía percutánea tiene alto porcentaje de éxito primario con muy baja tasa de complicaciones. El tratamiento por vía arterial pulmonar es un abordaje alternativo. La fibrobroncoscopía flexible es un importante complemento en esta entidad.

Abstract We present the results of 105 patients with life-threatening hemoptysis who were treated with the systemic arterial and/or pulmonary artery routes. We also describe the procedure techniques and the angiographic findings. We show the usefulness of the flexible fiberoptic bronchoscopy and chest radiography to identify the bleeding zone previous to the procedure. From May 2000 to September 2015, a total of 105 patients were admitted to the Catheterization Laboratory with a diagnosis of life-threatening hemoptysis; 76 were male (72.4%) and mean age was 41 ± 18.65 years. Treatment was successful in 93% (98/105). In 90% (88/98) the approach was via the bronchial arteries and/or non-bronchial systemic arteries, and in 10% (10/98) the approach was via the pulmonary artery. In bilateral affection angiographic images alone could not identify accurately the site of the lung bleeding. Flexible fibrobronchoscopy was performed in 60% (63/98) and located the bleeding area in 84% (56/63). In unilateral affection, chest radiography previous to the procedure located the bleeding area in 47%. No complications or death were related to the procedure. The treatment of life threatening hemoptysis by a percutaneous way has a high percentage of primary success with a very low incidence of complications. Pulmonary arterial route treatment is an alternative approach. Flexible fibrobronchoscopy is an important complement to this entity.

Aspectos broncoscópicos e histológicos en pacientes con cáncer de pulmón / Bronchoscopic and histologic aspects in patients with lung cancer

Introducción: Se denomina como cáncer de pulmón a un conjunto de enfermedades resultantes del crecimiento aberrante de células del tracto respiratorio, en particular del tejido pulmonar. Objetivo: Determinar los aspectos broncoscópicos e histológicos útiles en la confirmación del diagnóstico de dichas neoplasias malignas. Métodos: Se realizó una investigación descriptiva y transversal de los 346 pacientes atendidos por cáncer de pulmón en el Servicio de Neumología del Hospital General Docente Dr. Juan Bruno Zayas Alfonso de Santiago de Cuba durante los años 2016 y 2017, en quienes se realizó broncoscopia. Para ello se utilizaron las variables edad, sexo, técnica diagnóstica empleada, diagnóstico histopatológico, localización más frecuente. Resultados: Predominaron los pacientes en las edades entre los 56 y 75 años (66,1 %), así como el sexo masculino (65,0 %). La biopsia bronquial fue el procedimiento que mayormente reveló la presencia del cáncer (61,3 %) y el tipo histológico más frecuente fue el carcinoma epidermoide (67,8 %). Conclusiones: Se demostró la importancia de la broncoscopia y sus procedimientos diagnósticos para confirmar la existencia del proceso morboso.

Introduction: It is denominated as lung cancer to a group of diseases resulting from the abnormal growth of cells of the breathing tract, in particular of the lung tissue. Objective: To determine the useful bronchoscopic and histologic aspects in the confirmation of the diagnosis of these neoplasms. Methods: A descriptive and cross-sectional investigation of the 346 patients assisted due to lung cancer in the Pulmonology Service of Dr. Juan Bruno Zayas Alfonso Teaching General Hospital was carried out in Santiago de Cuba during 2016 and 2017 to whom a bronchoscopy was carried out. The variables used were age, sex, diagnostic technique used, histopatologic diagnosis and more frequent localization. Results: The patients aged 56 and 75 (66.1 %), as well as the male sex (65.0 %) prevailed. The bronchial biopsy was the procedure that mostly revealed the presence of cancer (61.3 %) and the most frequent histologic type was the squamous cell carcinoma (67.8 %). Conclusions: The importance of bronchoscopy and its diagnostic procedures to confirm the existence of the morbid process was demonstrated.

Empirical treatment of nontuberculosis mycobacterium infection after liver transplantation: one case report and literature review / 器官移植

Objective To summarize the clinical experience of diagnosis and treatment of nontuberculosismycobacterium (NTM) infection after liver transplantation. Methods Clinical experience of effective treatment of 1 case with NTM at 7th month after liver transplantation at the Shanghai Changzheng Hospital affiliated to the Second Military Medical University was summarized and literature review was performed. Results Following liver transplantation, the NTMpatient was clinically manifested with fever in the afternoon. CT scan prompted the progression of the disease. The lesions were enlarged and fused with thin-walled cavity in the right upper lung. The diagnosis of NTM infection was validated by fiberoptic bronchoscopy (brush or lavage approach), spot test of T cells infected with mycobacterium tuberculosis (T-SPOT. TB), multiple phlegm culture and empirical anti-tuberculosis therapy. The patient was effectively treated and successfullydischarged after diagnostic quadruple anti-tuberculosis therapy. The patient was followed up until the day of manuscript submission. The patient was physically stable without the symptoms of fever and cough with asthma. The liver function was normal. Conclusions The incidence of NTM infection is rare and inneglectable after liver transplantation. Application of fibrobronchoscopy via brush or lavage approach can enhance the positive diagnostic rate. Diagnostic quadruple antituberculosis therapy is efficacious for NTM infection.

Hemorragia alveolar difusa: Diez años de experiencia / Diffuse Alveolar Hemorrhage. Ten Year Experience

Introducción: Las manifestaciones registradas de la hemorragia alveolar difusa (HAD) están influenciadas por las características de los pacientes y la experiencia de los centros de referencias donde son asistidos. Objetivos: Describir los hallazgos clínicos y de laboratorio, las etiologías y los factores de riesgo de mortalidad en pacientes con HAD. Métodos: Análisis retrospectivo de los informes de flbrobroncoscopias en pacientes con diagnóstico de HAD (período 2003-2013), según etiologías inmunológicas y no inmunológicas. Resultados: Se identiflcaron 20 pacientes que presentaron los signos clínicos y patológicos de HAD sobre un total de 6839 flbrobroncoscopias (0,3%). La edad mediana fue 57 años (rango 20-88). Los signos más frecuentes de presentación fueron disnea e inflltrados radiológicos pulmonares en el 100% de los casos y anemia en el 95%. La clásica tríada semiológica (inflltrados radiológicos pulmonares, anemia y hemoptisis) de la HAD se encontró solo en 4 casos, 20%. La etiologías no inmunológicas fueron las más frecuentes (15 casos, 75%), especialmente infecciosas, oncohematológicas y cardiovasculares. La mediana de estadía hospitalaria fue de 17.5 días (rango 2-90 días). Doce pacientes fueron tratados en la UTI. La letalidad fue 60% (12/20 pacientes). Los principales riesgos de muerte fueron pacientes inmunocomprometidos (OR 27.50; IC 95%: 1.99 - 378.00, p = 0.013), necesidad de asistencia respiratoria mecánica (OR 18.00; IC 95%: 1.49-216.00, p = 0.023) y estadía en UTI (OR 7.50; IC 95%: 0.92-61.00, p = 0.049). La mortalidad a los 14 días de internación en el grupo no inmunológico fue superior a la del grupo inmunológico (p = 0.007) pero la mortalidad global no fue diferente (p = 0.066). Conclusiones: En nuestra serie, los principales signos clínicos fueron disnea, anemia e inflltrados pulmonares; pero la tríada clásica fue de rara observación. En todos nuestros pacientes fue posible adscribir la HAD a una etiología deflnida. Las principales etiologías fueron no inmunológicas. La estadía en UTI y la necesidad de ARM se asociaron a mayor riesgo de mortalidad. La mortalidad a mediano plazo no fue diferente entre ambos grupos.

Introduction: The registered manifestations of Diffuse Alveolar Hemorrhage (DAH) are influenced by the characteristics of the patients and the experience of the referral centers where they were assisted. Objectives: To describe clinical and laboratory findings, etiologies and risk factors for mortality of patients with DAH. Methods: A retrospective analysis of fibrobronchoscopy reports in patients with DAH diagnosis was carried out for the period 2003-2013, according to to immunological and non-immunological etiologies. Results: Twenty patients with clinical and pathologic signs of DAH were identified, mean age 57 years old (range 20-88). The most common signs of presentation were dyspnea and radiologic pulmonary infiltrates (100%), and anemia (95%). The classical clinical semiology of three signs (radiologic pulmonary infiltrates, anemia and hemoptisis) was present only in 4 cases (20%). The most frequent etiologies were no immunological (75%), especially infectious, oncohematologic and cardiovascular etiologies. The median hospital stay was 17.5 days (range 2-90 days). Twelve patients were admitted into the Intensive Care Unit. Case fatality was 60% (12/20 patients). The main risk factors for death were immunocompromised patients (OR 27.50; IC 95%: 1.99-378.00, p = 0.013), need for prescription of mechanical ventilation (OR was 18.00; IC 95%: 1.49-216.00, p = 0.023) and intensive care unit admission (OR 7.50 (IC 95%: 0.92-61.00, p = 0.049). Mortality at 14 days in the group not immunological was lower (p=0.007) but the overall mortality was not different (p=0.066). Conclusion: The main clinical manifestation was dyspnea, anemia and pulmonary infiltrates, while the classic triad was infrequent. In all the cases it was possible to attribute the DAH to a defined etiology. The main etiologies were no immunological. The stay in the intensive care unit, the necessity for mechanical ventilation and immunological etiologies were associated with a higher risk of mortality. The medium-term mortality was not different between the two groups.

Objective To retrospectively analyze of clinical application of BF-XP60 micro-bronchoscopy.Methods 135 clinical data of patients who adopted ultrafine micro-bronchoscopy and intervention were collected and analyzed for the complications.Results The frequency of local rhinomusoca damaging and errhysis was in 3 cases,the mucous of the glottis damaging and errhysis was in 2 cases,local mucous of the tracheal bronchus errhysis was in 3 cases.After intervention,the frequency of fever was in 13 cases,massive haemorrhage was in 1 case,pneumothorax was in 1 case,chest pain was in 2 cases,part fiber of inner untrafine micro-bronchoscopy broken was in 2 cases,check failure due to ultrafine micro-bronchoscopy broken in trachea was in 4 cases,and arrhythmia,asphyxia,and death were in 0 case.The overall incidence of side effects was 22.9％ (31/135).Conclusion Application of ultrafine micro-bronchoscopy was contributed to find the lesions within the bronchioles and around the lungs,moreover,it could evaluate the distal bronchus of airway obstruction which was planned to adopt intervention.The topic that how to reduce the incidence of the side effects of the micro-brohchoscopy and improve the success rate and safety of inspection and intervention was worth to be concerned.

The application of fibrobronchoscopy in extubation for patients suffering from acute exacerbation of chronic obstructive pulmonary disease with low cough peak expiratory flow / 中华危重病急救医学

Objective To investigate the value of the application of fibrobronchoscopy in extubation for patients suffering from acute exacerbation of chronic obstructive pulmonary disease(AECOPD)with low cough peak expiratory flow(CPEF). Methods A single-center prospective controlled study was conducted. The ventilated AECOPD patients who were cooperative at the time of extubation in Department of Critical Care Medicine of Guangzhou Institute of Respiratory Disease of Guangzhou Medical University from June 2009 to May 2014 were enrolled. All patients successfully passed the spontaneous breathing trial(SBT). Extubation was performed after determination of CPEF following energetic coughing. According to the CPEF,the patients were divided into CPEF≥60 L/min group (high CPEF group)and CPEF<60 L/min group(low CPEF group). After extubation,fibrobronchoscopic drainage was given to the patients in high CPEF group when necessary. Fibrobronchoscopic drainage was given to the patients in low CPEF group at least once a day,and the frequency of such treatment could be increased according to the patient's condition. If the patients did not require re-intubation within 48 hours,extubation was recorded as successful. The gender,age,acute physiology and chronic health evaluationⅡ(APACHEⅡ)score before extubation,ventilation time,the time of intensive care unit(ICU)stay,the mortality in ICU,the rate of re-intubation,the ability to cough and the frequency of application of fibrobronchoscopy after extubation were recorded. Results A total of 102 patients with AECOPD were enrolled,58 patients in high CPEF group and 44 in low CPEF group. Compared with high CPEF group,the mean age in low CPEF group was older(years:74.3±15.2 vs. 69.5±11.4,t=2.164,P=0.041),the time of ICU stay was significantly longer(days:20.1±11.2 vs. 17.4±7.3,t=2.274,P=0.030), but there was no significant difference in gender〔male/female(cases):35/9 vs. 45/13,χ2=0.057,P=0.812〕, APACHEⅡscore(11.9±1.9 vs. 10.3±4.2,t=1.290,P=0.200),mechanical ventilation time(days:14.8±10.8 vs. 13.3±9.6,t=0.677,P=0.501)and the rate of re-intubation〔18.18%(8/44)vs. 12.07%(7/58),χ2=1.412, P=0.235〕between low CPEF group and high CPEF group. The cough strength of patients in high CPEF group was almost alwaysstrong(52 cases),and in the low CPEF group,most of them wasmoderate(14 cases)orweak(26 cases). The frequency of application of fibrobronchoscopy in low CPEF group was higher than that in high CPEF group(times:4.1±1.8 vs. 1.3±0.9,t=2.626,P=0.011). All patients underwent weaning successfully,and no death occurred. Conclusion The application of fibrobronchoscopy in the extubated AECOPD patients with low CPEF can reduce the rate of re-intubation,avoid the prolonged ventilation,but cannot reduce the time of ICU stay.

Cuerpo Extraño Endobronquial. Presentación de un caso / Foreign body in airway. Case presentation

Introducción: los cuerpos extraños bronquiales en pacientes adultos constituyen una entidad clínica poco frecuente. La localización más habitual para un cuerpo extraño de vías respiratorias es el bronquio principal derecho. Objetivo: reflejar lo difícil que resulta en ocasiones diagnosticar un cuerpo extraño como causa de tos y disnea en un paciente adulto. Presentación del Caso: paciente de 72 años de edad, sin clínica respiratoria previa. Relata la enferma que 5 meses antes de acudir a nuestro Centro se encontraba tomando sopa, cuando nota como si hubiese "broncoaspirado algo", inicialmente comienza con "tos seca y sensación de ahogo", que cede espontáneamente pero no desaparece. Acude a nuestro hospital y se realiza fibrobroncoscopía observándose la presencia de un cuerpo extraño (hueso de pollo) a nivel de bronquio del lóbulo superior izquierdo procediéndose a su extracción. Conclusiones: en presencia de un paciente con tos y disnea después de un cuadro de broncoaspiración se debe tener en cuenta el diagnóstico de aspiración de un cuerpo extraño y la extracción de este resulta la solución definitiva.

Introduction: the bronchial strange bodies in adult patient constitute a clinic entity a little frequent. The more frequent location for strange body of respiratory tract is the right main bronchial. Objective: to show the difficulty to diagnose a foreign body as cause of cough and dyspnea in an adult patient. Case presentation: a patient of 72 years old is presented, without a previous respiratory clinic. The sick patient report that 5 month before going to our center, she was having soup, when she notes as if she had bronchoaspired something, first she started with a dry cough and a sensation of shortness of breath, which cedes spontaneously but didn't disappear. She came up to our hospital we made a fibrobronchoscopy to her, we could observe the presence of strange body (chicken bone) to the left upper lobule of the bronchial level; therefore we proceeded with the extraction of it. Conclusions: in the case of a patient presenting with cough and dyspnea after bronchoaspired something it is essential to take into account the diagnosis of the foreign body and the remove of strange body is the definitive solution.

Broncoscopia en el diagnóstico de las enfermedades respiratorias / Bronchoscopy in the diagnosis of respiratory diseases

Objetivo: describir los resultados de la aplicación de la broncoscopia en el diagnóstico de enfermedades respiratorias. Métodos: se realizó un estudio descriptivo de corte transversal en 116 pacientes a quienes se les efectuó broncoscopia. Las variables estudiadas fueron: edad, sexo, raza, indicación diagnóstica, hallazgos radiológicos, positividad de las técnicas aplicadas, rendimiento diagnóstico y complicaciones del proceder. Los datos obtenidos se resumieron mediante frecuencias simples, rangos y porcentaje. Se aplicaron pruebas de significación estadística chi cuadrado y el intervalo de confianza del 95 por ciento. Para determinar la asociación entre variables se utilizó el odds ratio. Resultados: el 73,2 por ciento de la muestra estuvo constituida por hombres entre 51 y 70 años de edad y el 52,6 por ciento mostró elementos de sospecha radiológica de cáncer como indicación diagnóstica. El engrosamiento hiliar fue el hallazgo radiológico más notificado (30,1 por ciento) y el que se asoció con mayor rendimiento diagnóstico. El cáncer resultó la enfermedad más diagnosticada (68,0 por ciento). El 70,3 por ciento de los casos presentó concordancia entre el diagnóstico macroscópico y microscópico. La biopsia endobronquial con fórceps mostró mayor positividad diagnóstica (66,6 por ciento). El sangramiento y la hipoxia se informaron como complicaciones menores en un 10,35 por ciento de los casos. Conclusiones: la broncoscopia constituye una importante herramienta diagnóstica en el ámbito de las enfermedades respiratorias, su mayor rendimiento se registra ante la sospecha clínico-radiológica de cáncer, fundamentalmente ante hallazgos que hagan suponer localizaciones centrales, de manera que la biopsia endobronquial con fórceps es la técnica más útil en estos casos; la ocurrencia de complicaciones, poco frecuente y menor, se relaciona con la aplicación de técnicas

Objective: describe the results of the use of bronchoscopy to diagnose respiratory diseases. Methods: a descriptive cross-sectional study was conducted with 116 patients who underwent bronchoscopy. The variables studied were age, gender, race, diagnostic indication, radiological findings, positivity of the techniques applied, diagnostic yield and procedural complications. The data obtained were summarized by means of simple frequencies, ranges and percentage. Chi-square tests of statistical significance were applied and the confidence interval was 95 percent. The odds ratio was used to determine the association between variables. Results: 73.2 percent of the sample were men aged 51-70, and 52.6 percent showed elements of radiological suspicion of cancer as diagnostic indication. Hilar widening was the radiological finding most commonly reported (30.1 percent), and was associated with a higher diagnostic yield. Cancer was the most commonly diagnosed condition (68.0 percent). 70.3 percent of cases showed agreement between macroscopic and microscopic diagnoses. Endobronchial biopsy with forceps exhibited a higher diagnostic positivity (66.6 percent). Bleeding and hypoxia were reported as minor complications in 10.35 percent of cases. Conclusions: bronchoscopy is an important tool for the diagnosis of respiratory diseases. Its highest yield is recorded in the presence of clinical-radiological suspicion of cancer, mainly when findings arouse suspicion of central localizations, which makes endobronchial biopsy with forceps the most useful technique in those cases. The occurrence of infrequent minor complications is associated with the application of techniques

Entrenador virtual de fibrobroncoscopia de bajo costo para enseñanza / Development of a virtual model of fibro-bronchoscopy

A virtual model of fibro-bronchoscopy is reported. The virtual model represents in 3D the trachea and the bronchi creating a virtual world of the bronchial tree. The bronchoscope is modeled to look over the bronchial tree imitating the displacement and rotation of the real bronchoscope. The parameters of the virtual model were gradually adjusted according to expert opinion and allowed the training of specialists with a virtual bronchoscope of great realism. The virtual bronchial tree provides clues of reality regarding the movement of the bronchoscope, creating the illusion that the virtual instrument is behaving as the real one with all the benefits in costs that this means.

Role of fibrobronchoscopy in diagnosis and treatment of severe chest trauma / 中华创伤杂志

Objective To explore the role of fibrobronchoscopy in diagnosis and treatment of se- vere chest trauma. Methods A retrospective analysis was done on 114 patients with severe chest trau- ma who were diagnosed and treated by fibrobronchoscope from January 1999 to July 2007. We finished 289 times of fihrohronchoscopies including 181 times through nasal cavity, 32 through tracheal, 52 through oral cavity and 56 through traeheostomy tube. SaO2 and arterial blood gas were monitored continu- ously before and after operation, and respirator support or oxygen was administered simultaneously. Re- suits Definite diagnosis was achieved in all patients, of whom were 102 patients treated with lavement. SaO2 was significantly increased in all patients after bronchial lavement (P <0.01) and Pao2 was signifi- candy ameliorated two hours after bronchial lavement (P < 0.05). Conclusions Fibrobronchoscopy can identify diagnosis of bronchial injury and remove foreign body, secretion, blood and phlegm for pa- tients with severe chest trauma. Meanwhile, fibrohronchoscopy can relieve obstructive atelectasis and ob- structive pneumonia, improve respiratory function and hence increase survival rate.
