Reverse partial pulmonary resection: a new surgical approach for pediatric pulmonary cysts / 南方医科大学学报

OBJECTIVE@#To evaluate the safety and efficacy of reverse partial lung resection for treatment of pediatric pulmonary cysts combined with lung abscesses or thoracic abscess.@*METHODS@#We retrospectively analyzed the clinical data of children undergoing reverse partial lung resection for complex pulmonary cysts in our hospital between June, 2020 and June, 2021.During the surgery, the patients lay in a lateral position, and a 3-5 cm intercostal incision was made at the center of the lesion, through which the pleura was incised and the fluid or necrotic tissues were removed.The anesthesiologist was instructed to aspirate the sputum in the trachea to prevent entry of the necrotic tissues in the trachea.The cystic lung tissue was separated till reaching normal lung tissue on the hilar side.The proximal end of the striated tissue in the lesion was first double ligated with No.4 silk thread, the distal end was disconnected, and the proximal end was reinforced with continuous sutures with 4-0 Prolene thread.The compromised lung tissues were separated, and the thoracic cavity was thoroughly flushed followed by pulmonary inflation, air leakage management and incision suture.@*RESULTS@#Sixteen children aged from 3 day to 2 years underwent the surgery, including 3 with simple pulmonary cysts, 11 with pulmonary cysts combined with pulmonary or thoracic abscess, 1 with pulmonary cysts combined with tension pneumothorax and left upper lung bronchial defect, and 1 with pulmonary herpes combined with brain tissue heterotaxy.All the operations were completed smoothly, with a mean operation time of 129 min, an mean hospital stay of 11 days, and a mean drainage removal time of 7 days.All the children recovered well after the operation, and 11 of them had mild air leakage.None of the children had serious complications or residual lesions or experienced recurrence of infection after the operation.@*CONCLUSION@#Reverse partial lung resection is safe and less invasive for treatment of complex pediatric pulmonary cysts complicated by infections.

Pneumonia, Multiple Pulmonary Infarction and Abscess Caused by a Bamboo Stick Accidentally Piercing into Chest: a Case Misdiagnosed as Pulmonary Tuberculosis / 中国医学科学杂志(英文版)

Computed tomography (CT) examination is the major measure for detecting and diagnosis of foreign bodies in human body. Although CT has high sensitivity in diagnosis of foreign body, some interference factors may still lead to missed diagnosis or misdiagnosis. Here we report a rare case that a bamboo stick accidentally pierced into the left chest of a young man who was drunk and unware of this hurt. The patient experienced cough, chest pain, fever, hemoptysis, and was misdiagnosed as primary and secondary tuberculosis based on chest CT examinations at a local hospital, although no tubercular bacillus detected by sputum smear. He subsequently received anti-tuberculous treatments in the following three years, but no improvement of his symptoms was observed. Until one month before his death, the bamboo stick was detected by spiral CT examination as well as three-dimensional image reconstruction at another hospital. Postmortem examination revealed pneumonia, pulmonary infarction, and abscess as the causes of his death. We analyze the potential reasons of misdiagnosis in this case, aiming to provide reference for the diagnosis and treatment of pulmonary inflammation associated with foreign body in the future.

Manejo quirúrgico del secuestro pulmonar complicado. Reporte de caso / Surgical management of the complicated pulmonary sequestration. A case report

Introducción: el secuestro pulmonar es una patología poco frecuente en la edad adulta, su mayor incidencia es en etapas tempranas de la vida. Se acompaña de infecciones pulmonares a repetición o crónicas severas, y puede asociarse a malformaciones congénitas. El diagnóstico se fundamenta en la detección de la irrigación anómala a través de un vaso de la circulación sistémica. Este caso nos permite plantear un diagnóstico diferencial en pacientes de edad adulta, aún cuando se trate de patología con mayor incidencia en niños y jóvenes, y poder orientar el manejo de acuerdo a esta posibilidad diagnóstica. Caso clínico: paciente femenino, de 19 años, con antecedente de asma e infecciones respiratorias a repetición de un mes de evolución. Ingresa con dificultad respiratoria, fiebre y tos productiva. Se realiza tomografía y Radiografía de tórax, en la que se evidencia imágenes compatibles con colección en campo pulmonar izquierdo y derrame pleural. Se realiza BAAR en esputo con resultado negativo para tuberculosis. Se realiza toracotomía posterolateral izquierda, resección de lóbulo inferior izquierdo, y se coloca dren pleural. Se identifica absceso pulmonar en lóbulo inferior izquierdo, y hallazgos anatómicos de secuestro pulmonar. Paciente presenta evolución favorable; el control clínico y radiográfico en el postoperatorio inmediato y mediato fue satisfactorio. Conclusión: presentamos el caso de edad adulta, donde un diagnóstico adecuado y un manejo multidisciplinario permiten una evolución satisfactoria de los pacientes.(AU)

Introduction: pulmonary sequestration is a rare disease in adulthood; its highest incidence is in early stages of life. It is accompanied by repeated or severe chronic lung infections, and may be associated with congenital malformations. The diagnosis is based on the detection of anomalous irrigation through a vessel of the systemic circulation.This case allows us to propose a differential diagnosis in patients of adulthood, even when it is pathology with higher incidence in children and young people, and guide the management according to this diagnostic possibility.Clinical case: female patient, 19 years old, with a history of asthma and respiratory infections after a month of evolution. The patient was admitted with respiratory distress, fever and productive cough.A tomography and chest X-ray are performed; that show images compatible with collection in the left pulmonary field and pleural effusion. BAAR is performed in sputum with a negative result for tuberculosis.Posterolateral left thoracotomy is performed, left lower lobe resection, and pleural drain is placed. Pulmonary abscess is identified in the left lower lobe, and findings of anatomical pulmonary sequestration. Patient presents positive evolution; The clinical and radiographic control in the immediate and intermediate postoperative period was satisfactory.Conclusion: we present the case of adulthood, where an adequate diagnosis and multidisciplinary management allows a satisfactory evolution of the patient.(AU)

Logistic regression analysis of clinical and computed tomography features of pulmonary abscesses and risk factors for pulmonary abscess-related empyema

OBJECTIVES: This study was conducted to investigate the risk factors for pulmonary abscess-related empyema by investigating the clinical characteristics and chest computed tomography imaging features of patients with pulmonary abscesses. METHODS: We retrospectively analyzed the chest computed tomography findings and clinical features of 101 cases of pulmonary abscess, including 25 cases with empyema (the experimental group) and 76 cases with no empyema (the control group). The potential risk factors for pulmonary abscess-related empyema were compared between the groups by using univariate and multivariate logistic regression analyses. RESULTS: The incidence of pulmonary abscess-related empyema was 24.8% (25/101). Univariate analysis showed that male gender, diabetes, pleuritic symptoms, white blood cells >10×109/L, albumin level <25 g/L, and positive sputum cultures were potential clinical-related risk factors and that an abscess >5 cm in diameter and transpulmonary fissure abscesses were potential computed tomography imaging-related risk factors for pulmonary abscess-related empyema. Multivariate logistic regression analysis showed that transpulmonary fissure abscesses (odds ratio=9.102, p=0.003), diabetes (odds ratio=9.066, p=0.003), an abscess >5 cm in diameter (odds ratio=8.998, p=0.002), and pleuritic symptoms (odds ratio=5.395, p=0.015) were independent risk factors for pulmonary abscess-related empyema. CONCLUSIONS: Transpulmonary fissure abscesses, diabetes, giant pulmonary abscesses, and pleuritic symptoms increased the risk of empyema among patients with pulmonary abscesses.

Introduction: Pulmonary abscess is an infrequent pathology in the pediatric age with a diverse etiology. The treatment is medical - surgical. Objective: To review the clinical presentation, bacteriology, images and outcomes of pulmonary abscesses in pediatric patients. Materials and Methods: This was an observational, descriptive study, carried out from January 2010 to September 2016. All patients under 16 years of age, with a diagnosis of pulmonary abscess verified by computerized axial tomography (CT), were included. We collected the relevant clinical, hematological, bacteriological, treatment and outcome information for each case. Results: 10 patients were included. They had an average age of 6 years, more frequently male. 80% developed as a complication of community-acquired pneumonia (CAP) and 100% were primary. The diagnosis was confirmed by chest CT. Staphylococcus aureus was isolated in 30% of cases. The right lung was the most frequently affected. All cases were cured with medical treatment only, using a third-generation cephalosporin, combined with an anti- staphylococcal antibiotic, with a treatment course of over 4 weeks. There were no deaths or readmissions. Conclusions: Pulmonary abscesses are rare. They can present as a complication of CAP or septicemia. They respond well to prolonged medical treatment and can occur in pediatric population without underlying pathologies.

El factor de riesgo más frecuente fue la no lactancia materna exclusiva (91,6 %) en el grupo de edad de 1-4 años. La fiebre, la polipnea y el tiraje estuvieron presentes en la mayoría de ellos. El pulmón derecho fue el más afectado en el 57,7 %, pero se registró mayor cifra de complicaciones en el izquierdo (58,2%). Las complicaciones más frecuentes fueron: el derrame pleural y el absceso pulmonar en 40,6 y 10,2 %, respectivamente. El tratamiento con penicilina cristalina sola se usó en el 36,3 % de los pacientes, y se logró una buena evolución clínica, sin hacer cambios terapéuticos. CONCLUSIONES: los pacientes en su totalidad evolucionan de forma favorable con los esquemas de antibióticos utilizados.

INTRODUCTION: acute respiratory infections, mainly pneumonias, are the main health problems in children aged under 5 years in developing countries. OBJECTIVE: to characterize the community-acquired severe pneumonia in the pneumonia management service. METHODS: a prospective, descriptive and cross-sectional study was conducted. There were selected those patients who were admitted to the pneumonia management service with community-acquired severe pneumonia and had been referred from the intensive care unit or the emergency service in the period of December 2005 to December 2010. One hundred and eighty seven patients in apparent healthy condition before the disease, who had been followed-up from the time of discharge from the hospital until their final medical discharge, were included in the research. A descriptive analysis of the clinical, radiological and therapeutic variables was made. RESULTS: of 187 patients, 76.4 % were aged under 5 years, 53.5 % were females. The most common risk factor was non-exclusive breastfeeding (91.6 %) in the 1-4 year age group. Fever, polypnea and tirage were present in most of them. The right lung was the most affected in 57.7 % of cases, but the left lung provided the highest number of complications (58.2 %). The most common complications were pleural effusion and the pulmonary abscess in 40.6 % and 10.2 %, respectively. The single crystalline penicillin treatment was used in 36.7 % of patients with good clinical progression with no further therapeutic changes. CONCLUSIONS: all the patients has favorable recovery with the antibiotic treatments used.

Resultados: de los 217 pacientes analizados, 149 (68,6 por ciento) tenían de 1 a 4 años, y el 53 por ciento era del sexo masculino. La fiebre, la polipnea y el tiraje estuvo presente en todos los pacientes. Las complicaciones más frecuentes fueron: el derrame pleural y el absceso pulmonar en 60,7 y 27,6 por ciento respectivamente. El pulmón derecho resultó el más afectado, pero el que más se complicó fue el izquierdo. Conclusiones: todos los pacientes tuvieron una evolución favorable, a pesar de que más de la mitad se complicaron. Se encontró que los pacientes con afectación en un solo pulmón, tienen más posibilidades de complicarse que cuando la afectación es bilateral

Introduction: pneumonia is one of the most important causes of mortality in the population under 5 years of age in the developing countries. Objective: to analyze the clinical and radiological expression and the progression of patients in a five-year period. Methods: a prospective, descriptive and cross-sectional study was performed on patients who had suffered severe community-acquired pneumonia and had been admitted to the respiratory disease center in the 2003 through 2007 period. They had been followed up at the outpatient service up to their discharge from hospital. The clinical and radiological variables were analyzed. Data were processed with the Chi-square test. Results: of 217 analyzed patients, 149 (68.6 percent) were one to 4 years-old and 53 percent were males. Fever, polypnea, and tirage were observed in patients. The most frequent complications comprised pleural effusion and pulmonary abscess in 60.7 and 27.6 percent of cases, respectively. The right lung was the most affected but complications were more common in the left lung. Conclusions: all the patients had favorable progression, although more than a half suffered complications. It was found that those patients with only one lung affected, were more likely to get complicated than those with both lungs affected by the disease

Técnica de Monaldi para el tratamiento de abscesos pulmonares / Monaldi's technique for treatment of pulmonary abscesses

Los abscesos pulmonares son tratados corrientemente con antibióticos y drenaje postural. Sin embargo, algunos pacientes no resuelven con las medidas conservadoras o presentan contraindicaciones para el tratamiento quirúrgico convencional. En tales individuos, el drenaje percutáneo (técnica de Monaldi) puede ser una alternativa de valor. El objetivo de este trabajo fue la presentación de 3 pacientes a quienes se les realizó el drenaje percutáneo de abscesos pulmonares. Se describen la técnica empleada para la inserción del tubo, las complicaciones y la evolución posoperatoria de los pacientes. En los 3 casos la operación fue exitosa, sin mortalidad y con una sola complicación, que fue una fístula broncopleurocutánea que requirió una intervención (neumonectomía) ulterior. El drenaje percutáneo de los abscesos pulmonares fue seguro y efectivo en estos pacientes(AU)
