RESUMO
OBJECTIVE: Pleural effusion is a common medical problem. It is important to decide whether the pleural fluid is a transudate or an exudate. This study aims to measure the attenuation values of pleural effusions on thorax computed tomography and to investigate the efficacy of this measurement in the diagnostic separation of transudates and exudates. MATERIALS AND METHODS: 380 cases who underwent thoracentesis and thorax computed tomography with pleural effusion were classified as exudates or transudates based on Light's criteria. Attenuation measurements in Hounsfield units were performed through the examination of thorax computed tomography images. RESULTS: 380 patients were enrolled (39 % women), the mean age was 69.9 ± 15.2 years. 125 (33 %) were transudates whereas 255 (67 %) were exudates. The attenuation values of exudates were significantly higher than transudates (15.1 ± 5.1 and 5.0 ± 3.4) (p < 0.001). When the attenuation cut-off was set at ≥ 10 HU, exudates were differentiated from transudates at high efficiency (sensitivity is 89.7 %, specificity is 94.4 %, PPV is 97 %, NPV is 81.9 %). When the cut-off value was accepted as < 6 HU, transudates were differentiated from exudates with 97.2 % specificity. CONCLUSION: The attenuation measurements of pleural fluids can be considered as an efficacious way of differentiating exudative and transudative pleural effusions.

Background: Bilothorax is defined as the presence of bile in the pleural space. It is a rare condition, and diagnosis is confirmed with a pleural fluid-to-serum bilirubin ratio of >1. Methods: The PubMed, Embase, Google Scholar, and CINAHL databases were searched using predetermined Boolean parameters. The systematic literature review was done per PRISMA guidelines. Retrospective studies, case series, case reports, and conference abstracts were included. The patients with reported pleural fluid analyses were pooled for fluid parameter data analysis. Results: Of 838 articles identified through the inclusion criteria and removing 105 duplicates, 732 articles were screened with abstracts, and 285 were screened for full article review. After this, 123 studies qualified for further detailed review, and of these, 115 were pooled for data analysis. The mean pleural fluid and serum bilirubin levels were 72 mg/dL and 61 mg/dL, respectively, with a mean pleural fluid-to-serum bilirubin ratio of 3.47. In most cases, the bilothorax was reported as a subacute or remote complication of hepatobiliary surgery or procedure, and traumatic injury to the chest or abdomen was the second most common cause. Tube thoracostomy was the main treatment modality (73.83%), followed by serial thoracentesis. Fifty-two patients (51.30%) had associated bronchopleural fistulas. The mortality was considerable, with 18/115 (15.65%) reported death. Most of the patients with mortality had advanced hepatobiliary cancer and were noted to die of complications not related to bilothorax. Conclusion: Bilothorax should be suspected in patients presenting with pleural effusion following surgical manipulation of hepatobiliary structures or a traumatic injury to the chest. This review is registered with CRD42023438426.

ABSTRACT: We assessed the preliminary efficacy and toxicity of intrapleural instillation of nivolumab in patients with large pleural effusion. Patients with metastatic cancers who have a large volume of pleural effusion and required evacuation were eligible. Thoracentesis followed by nivolumab (40 mg, single intrapleural instillation) was performed. The primary endpoint was 3-month recurrence-free survival. A total of 13 patients were enrolled. The study was terminated after stage 1 as no efficacy was observed; 7 patients (54%) had a recurrence of pleural effusion at 3 months. Thirteen (100%) patients had no recurrence, dyspnea, or cough within 1 month, and the median time to recurrence was 1.9 months (95% confidence interval [CI], 1.35-2.5). No adverse events were identified. We concluded that a single intrapleural instillation of the nivolumab at 40 mg was ineffective and well-tolerated in cancer patients with pleural effusion.

BACKGROUND: To investigate the accuracy of three model formulae for ultrasound quantification of pleural effusion (PE) volume in patients in supine position. METHODS: A prospective study including 100 patients with thoracentesis and drainage of PE was conducted. Three model formulae (single section model, two section model and multi-section model) were used to calculate the PE volume. The correlation and consistency analyses between calculated volumes derived from three models and actual PE volume were performed. RESULTS: PE volumes calculated by three models all showed significant linear correlations with actual PE volume in supine position (all p < 0.001). The reliability of multi-section model in predicting PE volume was significantly higher than that of single section model and slightly higher than that of two section model. When compared with actual drainage volume, the intra-class correlation coefficients (ICCs) of single section model, two section model and multi-section model were 0.72, 0.97 and 0.99, respectively. Significant consistency between calculated PE volumes by using two section model and multi-section model existed for full PE volume range (ICC 0.98). CONCLUSION: Based on the convenience and accuracy of ultrasound quantification of PE volume, two section model is recommended for pleural effusion assessment in routine clinic, though different model formulae can be selected according to clinical needs.

Introduction: Critical care, emergency medicine, and surgical trainees frequently perform surgical and Seldinger-technique tube thoracostomy, thoracentesis, and thoracic ultrasound. However, approaches to teaching these skills are highly heterogeneous. Over 10 years, we have developed a standardized, multidisciplinary curriculum to teach these procedures. Methods: Emergency medicine residents, surgical residents, and critical care fellows, all in the first year of their respective programs, underwent training in surgical and Seldinger chest tube placement and securement, thoracentesis, and thoracic ultrasound. The curriculum included preworkshop instructional videos and 45-minute in-person practice stations (3.5 hours total). Sessions were co-led by faculty from emergency medicine, thoracic surgery, and pulmonary/critical care who performed real-time formative assessment with standardized procedural steps. Postcourse surveys assessed learners' confidence before versus after the workshop in each procedure, learners' evaluations of faculty by station and specialty, and the workshop overall. Results: One hundred twenty-three trainees completed course evaluations, demonstrating stable and positive responses from learners of different backgrounds taught by a multidisciplinary group of instructors, as well as statistically significant improvement in learner confidence in each procedure. Over time, we have made incremental changes to our curriculum based on feedback from instructors and learners. Discussion: We have developed a unique curriculum designed, revised, and taught by a multidisciplinary faculty over many years to teach a unified approach to the performance of common chest procedures to surgical, emergency medicine, and critical care trainees. Our curriculum can be readily adapted to the needs of institutions that desire a standardized, multidisciplinary approach to thoracic procedural education.

PURPOSE: To determine the safety and efficacy associated with drainage volumes greater than 1,500 mL in a single, unilateral thoracentesis without pleural manometry measurements. MATERIALS AND METHODS: This retrospective, single-institution study included 872 patients (18 years and older) who underwent ultrasound-guided thoracentesis. Patient and procedures data were collected including demographics, number of and laterality of thoracenteses, volume and consistency of fluid removed, and whether clinical or radiologic evidence of re-expansion pulmonary edema (REPE) developed within 24 h of thoracentesis. Fisher's exact test was used to test the significance of the relationship between volume of fluid removed and evidence of REPE. RESULTS: A total of 1376 thoracenteses were performed among the patients included in the study. The mean volume of fluid removed among all procedures was 901.1 mL (SD = 641.7 mL), with 194 (14.1%) procedures involving the removal of ≥ 1,500 mL of fluid. In total, six (0.7%) patients developed signs of REPE following thoracentesis, five of which were a first-time thoracentesis. No statistically significant difference in incidence of REPE was observed between those with ≥ 1,500 mL of fluid removed compared to those with < 1,500 mL of fluid removed (p-value = 0.599). CONCLUSIONS: Large-volume thoracentesis may safely improve patients' symptoms while preventing the need for repeat procedures.

BACKGROUND AND OBJECTIVE: This study aims to quantify bedside pleural procedures performed at a quaternary teaching hospital describing technical and epidemiological aspects. MATERIALS AND METHODS: The authors retrospectively reviewed consecutive patients who underwent invasive thoracic bedside procedures between March 2022 and February 2023. RESULTS: 463 chest tube insertions and 200 thoracenteses were performed during the study period. Most procedures were conducted by 1st-year Thoracic Surgery residents, with Ultrasound Guidance (USG). There was a notable preference for small-bore pigtail catheters, with a low rate of immediate complications. CONCLUSION: Bedside thoracic procedures are commonly performed in current medical practice and are significant in surgical resident training. The utilization of pigtail catheters and point-of-care ultrasonography by surgical residents in pleural procedures is increasingly prevalent and demonstrates high safety.

Drug-induced pleural effusion is one of the rare causes of exudative pleural effusion and a high index of suspicion is necessary to lead to early diagnosis. We hereby present the case of a young male in his late 30s, known case of metastatic gastrointestinal stromal tumour on sunitinib therapy, who presented with right-sided mild pleural effusion. Diagnostic thoracentesis showed the effusion to be a monomorphic exudate with low adenosine deaminase, which was negative for malignant cells on cytopathology. A contrast-enhanced CT chest revealed an enlarged lymph node (LN) at the 4R station, cytological analysis of which was suggestive of reactive lymphoid hyperplasia. Infective workup of the LN aspirate and bronchoalveolar lavage taken from the right middle lobe was negative. After systematically excluding the usual causes of exudative pleural effusion, sunitinib was considered to be a possible cause and was, therefore, withheld. A repeat chest X-ray after 3 weeks of stopping the drug showed resolution of the pleural effusion.

BACKGROUND: Malignant pleural effusions (MPEs) are common, and a third of them have underlying trapped lung (TL). Management of MPE and TL is suspected to be heterogeneous. Understanding current practices in Australasia is important in guiding policies and future research. AIMS: Electronic survey of Australia-New Zealand respiratory physicians, thoracic surgeons and their respective trainees to determine practice of MPE and TL management. RESULTS: Of the 132 respondents, 56% were respiratory physicians, 23% were surgeons and 20% were trainees. Many respondents defined TL as >25% or any level of incomplete lung expansion; 75% would use large-volume thoracentesis to determine whether TL was present. For patients with TL, indwelling pleural catheters (IPCs) were the preferred treatment irrespective of prognosis. In those without TL, surgical pleurodesis was the most common choice if prognosis was >6 months, whereas IPC was the preferred option if survival was <3 months. Only 5% of respondents considered decortication having a definite role in TL, but 55% would consider it in select cases. Forty-nine per cent of surgeons would not perform decortication when the lung does not fully expand intra-operatively. Perceived advantages of IPCs were minimisation of hospital time, effusion re-intervention and usefulness irrespective of TL status. Perceived disadvantages of IPCs were lack of suitable drainage care, potentially indefinite duration of catheter-in-situ and catheter complications. CONCLUSION: This survey highlights the lack of definition of TL and heterogeneity of MPE management in Australasia, especially for patients with expandable lungs. This survey also identified the main hurdles of IPC use that should be targeted.

INTRODUCTION: Pleural effusions are known to occur in many cases of COVID-19. Data on typical characteristics of COVID-19-associated pleural effusions are limited. The goal of this project was to characterize the pleural fluid from patients with COVID-19. METHODS: We retrospectively collected electronic medical record data from adults hospitalized at a large metropolitan hospital system with COVID-19 infection who had a pleural effusion and a thoracentesis performed. We assessed pleural fluid characteristics and applied Light's criteria. RESULTS: We identified 128 effusions from 106 unique patients; 45.4% of the effusions had fluid/serum protein ratio greater than 0.5, 33.9% had fluid/serum lactate dehydrogenase (LDH) greater than 0.6, and 56.2% had fluid LDH greater than 2/3 of the serum upper limit of normal. Altogether, 68.5% of effusions met at least one of these three characteristics and therefore were exudative by Light's criteria. The white blood cell (WBC) differential was predominantly lymphocytic (mean 42.8%) or neutrophilic (mean 28.7%); monocytes (mean 12.7%) and eosinophils (mean 2.5%) were less common. CONCLUSION: We demonstrate that 68.5% of pleural effusions in patients with COVID-19 infection were exudative and hypothesize that COVID-19-associated pleural effusions are likely to be exudative with WBC differential more likely to be predominantly lymphocytic.

Thoracentesis is performed by 4 methods: gravity, manual aspiration, vacuum-bottle suction, and wall suction. This literature review investigates the safety of these techniques and determines if there is significant difference in complication rates. A comprehensive literature search revealed 6 articles studying thoracentesis techniques and their complication rates, reviewing 20,815 thoracenteses: 80 (0.4%) by gravity, 9431 (45.3%) by manual aspiration, 3498 (16.8%) by vacuum-bottle suction, 7580 (36.4%) by wall suction and 226 (1.1%) unspecified. Of the 6 studies, 2 were smaller with 100 and 140 patients respectively. Overall, there was a 4.4% complication rate including hemothoraces, pneumothoraces, re-expansion pulmonary edema (REPE), chest discomfort, bleeding at the site, pain, and vasovagal episodes. The pneumothorax and REPE rate was 2.5%. Sub-analyzed by each method, there was a 47.5% (38/80) complication rate in the gravity group, 1.2% (115/9431) in the manual aspiration group including 0.7% pneumothorax or REPE, 8% (285/3498) in the vacuum-bottle group including 3.7% pneumothorax or REPE, 4% (309/7580) in the wall suction group all of which were either pneumothorax or REPE, and 73% (166/226) in the unspecified group most of which were vasovagal episodes. Procedure duration was less in the suction groups versus gravity drainage. The 2 smaller studies indicated that in the vacuum groups, early procedure termination rate from respiratory failure was significantly higher than non-vacuum techniques. Significant complication rate from thoracentesis by any technique is low. Suction drainage was noted to have a lower procedure time. Symptom-limited thoracentesis is safe using vacuum or wall suction even with large volumes drained. Other factors such as procedure duration, quantity of fluid removed, number of needle passes, patients' BMI, and operator technique may have more of an impact on complication rate than drainage modality. All suction modalities of drainage seem to be safe. Operator technique, attention to symptom development, amount of fluid removed, and intrapleural pressure changes may be important in predicting complication development, and therefore, may be useful in choosing which technique to employ. Specific drainage modes and their complications need to be further studied.

BACKGROUND: Computed tomography (CT) scan is commonly performed for pleural effusion diagnostis in the clinic. However, there are limited data assessing the accuracy of thoracic CT for the separation of transudative from exudative effusions. The study aimed to determine the diagnostic value of thoracic CT in distinguishing transudates from exudates in patients with pleural effusion. METHODS: This is a two-center retrospective analysis of patients with pleural effusion, a total of 209 patients were included from The First Affiliated Hospital of Henan University of Science and Technology as the derivation cohort (Luoyang cohort), and 195 patients from the First Affiliated Hospital of Zhengzhou University as the validation cohort (Zhengzhou cohort). Patients who underwent thoracic CT scan followed by diagnostic thoracentesis were enrolled. The optimal cut-points of CT value in pleural fluid (PF) and PF to blood CT value ratio for predicting a transudative vs. exudative pleural effusions were determined in the derivation cohort and further verified in the validation cohort. RESULTS: In the Derivation (Luoyang) cohort, patients with exudates had significantly higher CT value [13.01 (10.01-16.11) vs. 4.89 (2.31-9.83) HU] and PF to blood CT value ratio [0.37 (0.27-0.53) vs. 0.16 (0.07-0.26)] than those with transudates. With a cut-off value of 10.81 HU, the area under the curve (AUC), sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of CT value were 0.85, 88.89%, 68.90%, 43.96%, and 95.76%, respectively. The optimum cut-value for PF to blood CT value ratio was 0.27 with AUC of 0.86, yielding a sensitivity of 61.11%, specificity of 86.36%, PPV of 78.57%, and NPV of 73.08%. These were further verified in the Validation (Zhengzhou) cohort. CONCLUSIONS: CT value and PF to blood CT value ratio showed good differential abilities in predicting transudates from exudates, which may help to avoid unnecessary thoracentesis.

INTRODUCTION: Pleural effusion is present in half of the patients hospitalised with acute heart failure. The condition is treated with diuretics and/or therapeutic thoracentesis for larger effusions. No evidence from randomised trials or guidelines supports thoracentesis to alleviate pleural effusion due to acute heart failure. The Thoracentesis to Alleviate cardiac Pleural effusion Interventional Trial (TAP-IT) will investigate if a strategy of referring patients with acute heart failure and pleural effusion to up-front thoracentesis by pleural pigtail catheter insertion in addition to pharmacological therapy compared with pharmacological therapy alone can increase the number of days the participants are alive and not hospitalised during the 90 days following randomisation. METHODS AND ANALYSIS: TAP-IT is a pragmatic, multicentre, open-label, randomised controlled trial aiming to include 126 adult patients with left ventricular ejection fraction ≤45% and a non-negligible pleural effusion due to heart failure. Participants will be randomised 1:1, stratified according to site and anticoagulant treatment, and assigned to referral to up-front ultrasound-guided pleural pigtail catheter thoracentesis in addition to standard pharmacological therapy or to standard pharmacological therapy only. Thoracentesis is performed according to local guidelines and can be performed in participants in the pharmacological treatment arm if their condition deteriorates or if no significant improvement is observed within 5 days. The primary endpoint is how many days participants are alive and not hospitalised within 90 days from randomisation and will be analysed in the intention-to-treat population. Key secondary outcomes include 90-day mortality, complications, readmissions, and quality of life. ETHICS AND DISSEMINATION: The study has been approved by the Capital Region of Denmark Scientific Ethical Committee (H-20060817) and Knowledge Center for Data Reviews (P-2021-149). All participants will sign an informed consent form. Enrolment began in August 2021. Regardless of the nature, results will be published in a peer-reviewed medical journal. TRIAL REGISTRATION NUMBER: NCT05017753.

Introducción: Los neumatoceles y las bulas pulmonares son lesiones que se observan en los niños casi siempre asociadas a neumonías infecciosas, aunque sus causas pueden ser diversas. La importancia clínica de estos procesos radica en el peligro de crecimiento progresivo, que puede comprometer las funciones respiratoria y cardiovascular. Objetivo: Describir las experiencias derivadas del proceso de diagnóstico por imágenes y del tratamiento invasivo de casos atendidos. Presentación de los casos: Desde finales de 2021 y durante un período de un año, se atendieron, en la unidad de cuidados intensivos pediátricos del Hospital Pediátrico Universitario de Cienfuegos, cinco niños con neumonías extensas, que desarrollaron bulas de gran tamaño varios días después del tratamiento antimicrobiano adecuado. Estas necesitaron drenaje y aspiración percutáneos debido a su magnitud y a la presencia de síntomas cardiovasculares. Conclusiones: Las bulas que aparecieron como complicación de la neumonía en el niño pueden presentarse con una frecuencia no despreciable, y hay que mantenerse atentos a su evolución, porque, a diferencia de los neumatoceles, pueden crecer progresivamente y comprometer las funciones respiratoria y cardiovascular. El drenaje percutáneo y aspiración continua por cinco días resultó un método seguro y eficaz para tratar estos procesos(AU)
Introduction: Pneumoatoceles and pulmonary bullae are lesions that are observed in children almost always associated with infectious pneumonia, although their causes may be diverse. The clinical importance of these processes lies in the danger of progressive growth, which can compromise respiratory and cardiovascular functions. Objective: To describe the experiences derived from the imaging process and the invasive treatment of treated cases. Presentation of the cases: Since the end of 2021 and for a period of one year, five children with extensive pneumonia were treated in the pediatric intensive care unit of the University Pediatric Hospital of Cienfuegos, who developed large bullae several days after appropriate antimicrobial treatment. The bullae required percutaneous drainage and aspiration due to their magnitude and the presence of cardiovascular symptoms. Conclusions: The bulla that appeared as a complication of pneumonia in the child can occur with a not negligible frequency, and it is necessary to be attentive to their evolution, because, unlike pneumoatoceles, can grow progressively and compromise respiratory and cardiovascular functions. Percutaneous drainage and continuous aspiration for five days was a safe and effective method to treat these processes(AU)

Introducción: Cerca del 50 % de los derrames pleurales (DP) es neoplásico. El comportamiento clínico del DP neoplásico es altamente sintomático por el gran volumen y su recidiva temprana. Propósito de la revisión: El objetivo de la revisión es delinear el papel de los diferentes métodos diagnósticos y terapéuticos de DP maligno. Buscamos reportes actualizados en donde se incluye los resultados de mejor supervivencia para los distintos tratamientos actuales. Recientes hallazgos: Los criterios de Light es el método estándar para diferenciar un exudado maligno. La toracocentesis guiada por ultrasonido debe ser usada como método diagnóstico/terapéutico. En pacientes con DP maligno se recomienda el drenaje permanente con el posicionamiento de un tubo de tórax y un sello hidráulico con drenaje cerrado. La pleurodesia con instilación de talco está recomendada en pacientes con DP maligno en busca de disminuir el volumen, las recidivas del DP y el tiempo de hospitalización. Conclusiones: Para el correcto manejo del DP maligno, hay que tomar en cuenta varios aspectos, como identificar la presencia de células malignas mediante estudio citológico y descartar una infección. La ecografía pleural permite definir el volumen del DP y permite decidir drenaje en ese momento, con la posibilidad de inserción de catéter intrapleural, con el objetivo de evaluar la posibilidad de esclerosar las pleuras a través de pleurodesia. Sin embargo, para llegar a esta decisión hay que analizar cada uno de los detalles que podrían tener un papel de importancia para el buen manejo y resolución definitiva o por el contrario decidir el manejo a título paliativo, siempre analizando cada caso con el objetivo de proveer de mejoría de síntomas y mejorar la calidad de vida del paciente.
Introduction: Approximately 50% of pleural effusions (PE) are neoplastic. The clinical behavior of neoplastic PE is highly symptomatic due to its large volume and early recurrence. Purpose of review: This review aims to outline the role of the different diagnostic and therapeutic methods of malignant PE. We look for updated reports that include the best survival results for the other current treatments. Recent findings: Light's criteria are the standard to differentiate a malignant exudate. Ultrasound-guided thoracentesis should be used as a diagnostic/therapeutic method. In patients with malignant PE, permanent drainage is recommended with the placement of a chest tube and a hydraulic seal with closed drainage. Pleurodesis with the installation of talc is recommended in patients with malignant PE to reduce volume, PE recurrences, and hospitalization time. Conclusions: For the correct management of malignant PE, several aspects must be considered, such as identifying the presence of malignant cells by cytological study and ruling out infection. Pleural ultrasound allows for defining the volume of the PE. It will enable deciding on drainage at that time, with the possibility of inserting an intrapleural catheter, to evaluate the likelihood of sclerosing the pleurae through pleurodesis. However, to reach this decision, it is necessary to analyze each of the details that could play an essential role in good management and definitive resolution or, on the contrary, decide on palliative management, constantly investigating each case to provide symptom improvement. In addition, improving the patient's quality of life.

Introducción: El neumotórax espontáneo es la causa más frecuente de ingreso urgente en los servicios de cirugía torácica. Objetivo: Caracterizar a pacientes ingresados con diagnóstico de neumotórax espontáneo. Métodos: Se realizó un estudio descriptivo de 93 pacientes con diagnóstico clínico y radiológico de neumotórax espontáneo, se establecieron las variables del estudio y se utilizaron frecuencias absolutas y porcentajes. Para la asociación de las variables se empleó el estadígrafo ji cuadrado con un nivel de confiabilidad del 95 por ciento. Resultados: Predominó el neumotórax espontáneo primario (65,5 por ciento), el sexo masculino fue el más afectado (80,6 por ciento), con mayor frecuencia en el hemitórax derecho (72,2 por ciento) y el tabaquismo como antecedente (83,9 por ciento). La pleurostomía mínima fue el tratamiento definitivo en el 72 por ciento de los pacientes. La complicación más frecuente después de la pleurostomía, fue la fuga persistente de aire. El tratamiento quirúrgico con pleurodesis mecánica, ofreció un 100 por ciento de efectividad. La mortalidad quirúrgica fue nula. Conclusiones: El neumotórax espontáneo predomina en el sexo masculino en una proporción de 4,2:1, en pacientes menores de 40 años de edad. El antecedente patológico personal que más se asocia es la enfermedad pulmonar obstructiva crónica. El síntoma predominante es el dolor torácico. El neumotórax espontáneo primario fue más frecuente y el hemitórax derecho el más afectado. El tabaquismo está presente como antecedente en ambos tipos de neumotórax espontáneo. La modalidad de tratamiento más utilizada es la pleurostomía mínima(AU)
Introduction: Spontaneous pneumothorax is the most frequent cause of urgent admission to thoracic surgery services. Objective: To characterize patients admitted with a diagnosis of spontaneous pneumothorax. Methods: A descriptive study of 93 patients with a clinical and radiological diagnosis of spontaneous pneumothorax was carried out, the study variables were established and absolute frequencies and percentages were used. For the association of the variables, the chi square statistic was used with a confidence level of 95 percent. Results: Primary spontaneous pneumothorax predominated (65.5 percent), the male sex was the most affected (80.6 percent), with greater frequency in the right hemithorax (72.2 percent) and smoking as the antecedent (83.9 percent). Minimal pleurostomy was the definitive treatment in 72 percent of the patients. The most frequent complication after pleurostomy was persistent air leak. Surgical treatment with mechanical pleurodesis offered 100 percent effectiveness. There was not surgical mortality. Conclusions: Spontaneous pneumothorax predominated in males in a ratio of 4.2: 1, in patients under 40 years of age. The most associated personal pathological history was chronic obstructive pulmonary disease. The predominant symptom was chest pain. Primary spontaneous pneumothorax was more frequent and the right hemithorax the most affected. Smoking was present as a history in both types of spontaneous pneumothorax. The most widely used treatment modality was minimal pleurostomy(AU)

El empiema es una colección de líquido purulento en el espacio pleural. La causa más común es la neumonía. Las opciones de tratamiento incluyen toracocentesis terapéutica, colocación de catéter de drenaje, terapia fibrinolítica, pleurodesis y cirugía, como la decorticación pleural. El drenaje pleural es eficaz en la etapa I y la cirugía está reservada para casos complicados (estadios II y III). En estos casos, es necesaria la decorticación pulmonar. Actualmente, el enfoque más favorecido para la decorticación es mediante una toracotomía abierta. Este es un estudio observacional, descriptivo, de corte transversal, retrospectivo, con un muestreo no probabilístico de casos consecutivos que tuvo como población accesible a pacientes con el diagnostico de empiema en quienes se realizó una decorticación pleural en el Hospital de Clínicas por el Departamento de Cirugía de Tórax durante el periodo de marzo 2016 a febrero 2019. Un total de 24 pacientes con el diagnóstico de empiema fueron sometidos a una decorticación pleural. La etiología de empiema más frecuente (75%) fue el derrame paraneumónico. Las complicaciones post quirúrgicas estuvieron presentes en 9 (37,5%) pacientes, de estos, 4 (17%) presentaron fuga aérea durante los primeros días postoperatorios. Se constató la resolución completa del cuadro en 21 (87,5%) pacientes y 3 (12,5%) pacientes presentaron colección residual pleural. Se constató recurrencia en 1 (4%) paciente, requiriendo un re intervención quirúrgica. En conclusión, la casuística de nuestro departamento de tórax coincide en cuanto a valores internacionales de complicaciones, resolución y mortalidad.
Empyema is a collection of purulent fluid in the pleural space. The most common cause is pneumonia. Treatment options include therapeutic thoracentesis, drainage catheter placement, fibrinolytic therapy, pleurodesis, and surgery, such as pleural decortication. Pleural drainage is effective in stage I and surgery is reserved for complicated cases (stages II and III). In these cases, pulmonary decortication is necessary. Currently, the most favored approach to decortication is by open thoracotomy. This is an observational, descriptive, cross-sectional, retrospective study, with a non-probabilistic sampling of consecutive cases that had as the accessible population, patients with the diagnosis of empyema in whom pleural decortication was performed at the Clinica´s Hospital of San Lorenzo, by the Department of Thoracic Surgery during the period from March 2016 to February 2019. A total of 24 patients with the diagnosis of empyema underwent pleural decortication. The most frequent aetiology of empyema (75%) was parapneumonic effusion. Post-surgical complications were present in 9 (37.5%) patients, of these, 4 (17%) presented air leakage during the first postoperative days. Complete resolution of the condition was verified in 21 (87.5%) patients and 3 (12.5%) patients presented residual pleural collection. Recurrence was found in 1 (4%) patient, requiring reoperation. In conclusion, the casuistry of our thoracic department coincides in terms of international values of complications, resolution and mortality.

ABSTRACT Over one million cases of the SARS-CoV-2 virus have been confirmed worldwide, with the death toll exceeding 50,000 people. An important issue to be addressed concerns the exposure of health professionals to this new virus. The first reports from Wuhan province, China, described infection rates of up to 29% among healthcare professionals before the use of personal protective equipment (PPE) was fully regulated. There are several protocols on the correct use of PPE during aerosol-generating procedures. However, there is no specific guidance on how to proceed in cases of need for chest tubes in patients with positive COVID-19 active air leak. The objective of this work is to assist surgeons of the most diverse specialties during the chest drainage of a patient with COVID-19 and to avoid a risk of contamination to the professional and the environment.
RESUMO Mais de um milhão de casos do vírus SARS-CoV-2 foram confirmados em todo o mundo, com o número de mortos ultrapassando 50.000 pessoas. Uma questão importante a ser abordada diz respeito à exposição dos profissionais de saúde à esse novo vírus. Os primeiros relatórios da província de Wuhan, na China, descreveram taxas de infecção de até 29% entre os profissionais de saúde antes que o uso de equipamentos de proteção pessoal (EPI) fosse totalmente regulamentado. Existem vários protocolos sobre o uso correto de EPI durante os procedimentos geradores de aerossóis. No entanto, não há orientação específica sobre como proceder em casos de necessidade de drenos torácicos em pacientes com vazamento de ar ativo COVID-19 positivos. O objetivo desse trabalho é auxiliar os cirurgiões das mais diversas especialidades durante a drenagem torácica de um paciente com COVID-19 e evitar um risco de contaminação ao profissional e no ambiente.

O hemangioma esplênico, tumor benigno mais frequente do baço, porém, por vezes de difícil diagnóstico, pode integrar a síndrome de Kasabach-Merritt, afecção rara e potencialmente fatal, descrita como associação entre hemangioma, trombocitopenia e coagulopatia de consumo. Apresentamos um caso de paciente de 73 anos em acompanhamento com a hematologia por trombocitopenia crônica a princípio idiopática, que evoluiu com dor abdominal, anemia e derrame pleural. Foi realizada tomografia computadorizada de abdome, que evidenciou massa esplênica sólida heterogênea. A paciente foi submetida a esplenectomia total videolaparoscópica e evoluiu com melhora da dor abdominal e normalização da série plaquetária, sem recorrência do derrame pleural após o procedimento. A raridade e a complexidade do caso, somadas à dificuldade diagnóstica e à abordagem terapêutica, foram fatores que corroboraram para a apresentação desse caso. (AU)
Splenic hemangioma, the most common, but sometimes hard to diagnose, benign tumor of the spleen may integrate Kasabach- Merritt syndrome, a rare and potentially fatal condition described as an association ofhemangioma, thrombocytopenia and consumption coagulopathy. We present a case of a 73-year-old female patient being monitoring, with Hematology due to chronic idiopathic thrombocytopenia who progressed with abdominal pain, anemia and pleural effusion; a computed tomography scan of the abdomen was performed, showing a heterogeneous solid splenic mass. The patient underwent total videolaparoscopic splenectomy and progressed with improvement of abdominal pain and normalization of the platelet series, with no recurrence of pleural effusion after the procedure. The rarity and complexity of the case added to the diagnostic difficulty and therapeutic approach were factors that corroborated for the presentation of this case. (AU)

A endometriose torácica é uma forma de endometriose extrapélvica encontrada em tecidos pulmonares ou na pleura. Caracteriza- se clinicamente pela presença de pneumotórax catamenial, hemotórax catamenial, hemoptise e nódulos pulmonares. O pneumotórax catamenial é a manifestação mais frequente, sendo caracterizado pelo acúmulo recorrente de ar na cavidade torácica durante o período menstrual. Ocorre, geralmente, no hemitórax direito e possui maior incidência na faixa etária dos 30 aos 40 anos de idade. Nosso objetivo é descrever um caso de derrame pleural hemorrágico recorrente e pneumotórax espontâneo correlacionados ao período menstrual em paciente de 34 anos. (AU)
Thoracic endometriosis is a form of extrapelvic endometriosis found in pulmonary tissue or the pleura. Clinically, it is characterized by the presence of catamenial pneumothorax, catamenial hemothorax, hemoptysis, and pulmonary nodules. The most frequent clinical presentation is catamenial pneumothorax, which is typified by a recurrent collection of air in the thoracic cavity occurring in conjunction with menstrual periods. It occurs more commonly on the right side and its highest incidence is between 30 and 40 years of age. Our objective is to describe a case of recurrent hemorrhagic pleural effusion and spontaneous pneumothorax correlated to the menstrual period in a 34-year-old patient. (AU)
