Fuga gaseosa persistente posoperatoria / Posoperative Persistent Gas Leak

Introducción: La fuga gaseosa persistente es la complicación posoperatoria más frecuente en cirugía torácica. En la actualidad no hay estudios con suficiente evidencia científica que permitan establecer una norma para el tratamiento de esta complicación. Objetivo: Ofrecer una actualización de los factores predisponentes de la fuga gaseosa, así como las modalidades de tratamiento que han surgido en los últimos años. Métodos: Se realizó una revisión bibliográfica en bases de datos MEDLINE (PubMed), SciELO, así como Google académico. Se tuvieron en cuenta variables como tipo de resección pulmonar, tiempo quirúrgico, complicaciones posoperatorias, se emplearon las palabras claves en idioma español e inglés y se seleccionaron un total de 44 artículos publicados desde el 1998 hasta el 2020. Desarrollo: Aunque por lo general esta complicación se considera leve, puede llegar a tener una incidencia de un 46 por ciento, asociándose a un aumento en la estadía hospitalaria, con repercusión en el costo sanitario, así como incomodidad y morbilidad para el paciente. En dependencia del momento en que se presente y su localización el tratamiento incluirá diferentes alternativas que abarcan desde la conducta conservadora, hasta diferentes modalidades de pleurodesis, tratamiento endoscópico o quirúrgico. Conclusiones: La resolución de esta entidad se produce en la mayoría de los pacientes mediante el empleo de sonda pleural, mientras que en el resto se requerirán estrategias alternativas, siendo importante el conocimiento por parte de los cirujanos de su forma de prevención, así como de todas las opciones terapéuticas, para su adecuado empleo en base a su criterio o experiencia(AU)

Introduction: Persistent gas leak is the most common postoperative complication in thoracic surgery. Currently there are no studies with sufficient scientific evidence to establish a standard for the treatment of this complication. Objective: To offer an update of the predisposing factors of gas leak, as well as the treatment modalities that have emerged in recent years. Methods: A bibliographic review was carried out in MEDLINE (PubMed), SciELO databases, as well as in academic Google. Variables such as type of lung resection, surgical time, and postoperative complications were taken into account. The keywords in Spanish and English were used and a total of 44 articles published from 1998 to 2020 were selected. Discussion: Although this complication is generally considered mild, it can have 46 percent incidence, being associated with an extra time of the hospital stay, affecting health costs, as well as discomfort and morbidity for the patient. Depending on when it occurs and its location, the treatment will include different alternatives that range from conservative management, to different modalities of pleurodesis, endoscopic or surgical treatment. Conclusions: The resolution of this entity occurs in most patients through the use of a chest tube, while alternative strategies will be required for the rest. It is important for surgeons to know their form of prevention, as well as all the therapeutic options, for their proper use based on their criteria or experience(AU)

Risk factors related to pleural empyema after talc slurry pleurodesis

Abstract Objective: Empyema is a complication of talc-pleurodesis that may lead to further surgical intervention and death. Therefore, the present study's objective was to identify the risk factors for the development of post-pleurodesis empyema after talc slurry pleurodesis in order to better select patients for this procedure and minimize its morbidity. Methods: Patients with malignant pleural effusion who underwent talc slurry pleurodesis at the present institution from January 2018 to January 2020 were retrospectively analyzed. Post-pleurodesis empyema was defined as pleural infection up to 30 days after pleurodesis. Using Cox regression analysis, significant prognostic factors for the development of empyema were examined. Results: Of the 86 patients identified for inclusion in the study, 62 were women (72%). Their mean age was 56.3±12.6 years. The median pleural drainage time was 9 days, and 20 patients (23.3%) developed empyema. In the univariate analysis, both drainage time (p = 0.038) and the use of antibiotics prior to pleurodesis (p < 0.001) were risk factors for pleural empyema. Multivariate analysis also identified the use of antibiotics as an independent risk factor (Odds Ratio [OR] 9.81; 95% Confidence Interval [95% CI] 2.87-33.54). Although the pulmonary expansion was not associated with empyema in the multivariate analysis, patients with less than 50% pulmonary expansion had a 4.5-times increased risk of empyema (95% CI 0.90-22.86; p = 0.067), and patients with 50-70% pulmonary expansion had a 3.8-times increased risk of empyema (95% CI 0.98-15; p = 0.053) after pleurodesis. Conclusion: The study suggests that antibiotic therapy prior to talc slurry pleurodesis may increase the risk of developing empyema. Furthermore, pleurodesis should be considered with caution in patients with long-duration chest tube placement and incomplete lung expansion.

Efficacy of Doxycycline as Peluridising Agent in Cases of Malignant Pleural Effusion (MPE)

Objective: To determine the efficacy of doxycycline as pleuridising agent in cases of malignant pleural effusions (MPE). Subject and methods: This was a descriptive case series that was conducted at Medical and Pulmonology Department of Combined Military Hospital Lahore from January 2018 to August 2018. In this study, the cases of malignant pleural effusion assessed on history and proven by histopathology on any biopsy of either gender falling in range of 30 years or more were included. The pleural fluid was drained by appropriate size intercostal chest tube (ICT). These cases then underwent pleurodesis with Doxycycline. For pleurodesis 10 capsule of Doxycycline each carrying 100 mg in it were taken and mixed with 50 ml of normal saline. A repeat chest X-ray and USG chest was done to see for presence of fluid, complete absence of fluid was labelled as efficacious pleurodesis. Results: In this study, there were total 60 cases of malignant pleural effusion (MPE) included, out of which 35 (58.33%) were females and 25 (41.67%) females. The mean age of the subjects was 57.32 ± 7.28 years. There were 29 (48.33%) cases with CA breast, 22 (36.67%) with CA lung and 9 (15%) had the other miscellaneous malignancies. The efficacy of pleurodesis with Doxycycline was seen in 26 (43.33%) of cases. There was significant better efficacy (p=0.001) in cases that had pleural effusion less than 1 liter at presentation where it was seen in 14 (63.64%) of cases as compared to 12 (31.58%) cases that had effusion less than 1 liter. There was no significant difference in terms of duration of pleural effusion with p=0.21. Conclusion: Doxycycline is efficacious in almost half of the cases and it is significantly better in cases that had effusion less than 1 liter.

Avaliação da eficácia e da toxicidade da solução de hipoclorito de sódio a 1% na indução de pleurodese em coelhos albinos / Evaluation of efficacy and toxicity of 1% sodium hypochlorite solution in the induction of pleurodesis in albino rabbits

Objetivo: verificar a eficácia e analisar possíveis alterações toxicológicas da indução de pleurodese com hipoclorito de sódio a 1% em modelos animais. Métodos: ensaio pré-clínico, randomizado com coelhos albinos (G1 e G2). Em G1 realizou-se pleurodese através da instilação 10ml de solução de hipoclorito de sódio a 1%. Em G2, 10ml de solução fisiológica a 0,9%. Traçaram-se perfis bioquímicos, de ambos os grupos, prés e pós-operatórios, para identificar alterações toxicológicas, comparados através do Teste Wilcoxon. Os animais foram eutanasiados, aleatoriamente, após 1, 7 ou 30 dias para autópsia, determinando a eficácia da pleurodese conforme a presença ou não de aderências na cavidade torácica. Os grupos foram comparados através do teste qui-quadrado (p<0,05). O projeto de pesquisa foi aprovado pelo comitê de ética em pesquisa em animais da Universidade Regional de Blumenau sob o protocolo 022/04. Resultados: foram incluídos 44 coelhos, 21 pertencentes ao G1 e 23 ao G2. 90,48% dos animais de G1 apresentaram aderências pleurais e apenas 10% de G2 (p <0,001). Quanto à análise da toxicidade, verificaram-se alterações significativas referentes às enzimas preditoras das funções cardíaca e hepática em ambos os grupos. Conclusões: a pleurodese com hipoclorito de sódio mostrou-se eficaz. As alterações bioquímicas em ambos os grupos devem-se, provavelmente, a um fator intrínseco do procedimento e não às substâncias. Não foram evidenciados prejuízos significativos decorrentes da solução proposta.

Aims: to verify the efficacy and possible toxicological alterations of the 1% sodium hypochlorite solution in the induction of pleurodesis in albino rabbits. Methods: randomized preclinical trial (G1 and G2) with rabbits. In the G1 the pleurodesis was done by the instilation of 10ml of a 1% sodium hypochlorite solution (SHS), and in the G2 by the instilation of 10ml of physiological solution (0,9%). Preoperatory and postopetary biochemical profiles were done in both groups in order to identify toxicological alterations. These profiles were compared by the Wilxcoxon Test. The animals were randomly euthanized after one, seven or thirty days for an autopsy. The efficiency of the pleurodesis was measured according to the presence or not of macroscopic adhesions in the thoracic cavity. Findings in both groups were compared by the chi-square test (p<0,05). The research project was approved by the ethical committee envolving animals research of the Regional University of Blumenau under the protocol 022/04. Results: 44 rabbits were included. 21 from G1 and 23 from G2. 90,48% of the G1 animals showed pleural adhesions while 10% of the G1 did. Concerning the toxicologycal analysis, signifficant alterations were found in the cardiac and hepatic enzymes in both groups. Conclusion: pleurodesis induced by the SHS was shown to be effective. G1 and G2 exhibited toxicologycal alterations probably due to an intrinsic factor of the procedure and not caused by the different solutions used. The animals responded well to the proposed agent, no systemic effects were evidenced.

Pleurodesis: A Comparision of Two Sclerosing Agents for Pleural Effusion

Introduction: Pleural effusion is one of the most frequentlyencountered pathology in our hospital. Thoracocentesis,thoracostomy, pleurodesis is the most commonly usedtreatment options for recurrent and persistent pleural effusion.Sterile talc powder is most commonly used as an sclerosingagent. In our study we have used sodium tetradecyl sulfateas a newer sclerosing agent and we have compared thecomplication rate, clinical response and success rate inboth sodium tetradecyl sulfate and talc sclerosing agent forpleurodesis. Study aimed to compare the safety and efficacyof the sodium tetradecyl sulfate and talc as a pleurodesis agentin pleural effusion cases.Material and methods: Pleural effusion cases (both malignantand non-malignant cases) were randomly allocated into groupA or group B. Group A patients were treated with 60mg of3% sodium tetradecyl sulfate, Group B patients were treatedwith 2 grams of sterile talc powder. Clinical data regardinggeneral complications, the rate of success, reduction in ICDdrainage and lung expansion were noted for every patient whounderwent pleurodesis.Results: 25 patients were allocated in each group. Patientscharacteristics were balanced between the two groups withthe majority of pleural effusion malignant in etiology. There isa statistically significant difference between the use of sodiumtetradecyl sulfate and talc in clinical response, ICD drainageand lung re-expansion. Sodium tetradecyl sulfate patient hasbetter lung reexpansion and clinical response in comparison totalc powder. The general complication was observed to be lowwith sodium tetradecyl sulfate than talc pleurodesis.Conclusion: Sodium tetradecyl sulfate pleurodesis appearsto have better pleurodesis effect than talc pleurodesis in ourstudy

Hidrotórax hepático: presentación de 3 casos con diferentes enfoques terapéuticos / Hepatic hydrothorax: presentation of 3 cases with different therapeutic approaches

El hidrotórax hepático (HH) se define como un derrame pleural mayor de 500 ml en pacientes con cirrosis e hipertensión portal. Representa una complicación infrecuente por lo general asociada con ascitis y su origen se relaciona con el paso de líquido ascítico a través de pequeños defectos en el diafragma de predominio en el hemitórax derecho. Una vez establecido el diagnóstico por imágenes, la toracentesis diagnostica permite confirmar un trasudado. La terapia inicial está basada en la restricción de sodio y el uso combinado de diuréticos. El 20-25% de los pacientes desarrolla un HH refractario, el cual requiere intervenciones invasivas tales como la derivación percutánea portosistémica intrahepática (DPPI), la reparación de los defectos diafragmáticos por videotoracoscopia asistida asociada a pleurodésis química y el uso de un catéter pleural tunelizado. No se recomienda la inserción de un tubo de tórax por su elevada morbilidad y mortalidad. El tratamiento definitivo del HH es el trasplante hepático el cual alcanza una excelente sobrevida. Presentamos tres casos de hidrotórax hepático con diferentes enfoques terapéuticos que incluyeron el manejo conservador con dieta y diuréticos, la inserción fallida de un tubo de tórax con pleurodesis y una DPPI.

Hepatic hydrothorax is uncommon transudative pleural effusion greater than 500 ml in association with cirrhosis and portal hypertension. Ascites is also present in most of the patients and the pathophysiology include the passage of ascites fluid through small diaphragmatic defects. After diagnostic thoracentesis studies, the first line management is restricting sodium intake and diuretics combination including stepwise dose of spironolactone plus furosemide. Therapeutic thoracentesis is a simple and effective procedure to relief dyspnea. Hepatic hydrothorax is refractory in approximately 20-25% and treatments options include repeated thoracentesis, transjugular intrahepatic portosystemic shunts (TIPS) placement, chemical pleurodesis with repair diaphragmatic defects using video-assisted thoracoscopy surgery (VATS), and insertion of an indwelling pleural catheter. Chest tube insertion carries significant morbidity and mortality with questionable benefit. Hepatic transplantation remains the best treatment option with long term survival. We present three cases of hepatic hydrothorax with different therapeutic approach including first line management, failed chest tube insertion and TIPS placement.

Talco estéril versus yodopovidona en pleurodesis como tratamiento del derrame pleural maligno. Estudio prospectivo no aleatorizado / Sterile talc versus povidone-iodine in pleurodesis as a treatment for malignant pleural effusion. Non-randomized prospective study

Comparar el uso del talco estéril versus yodopovidona como agentes químicos en pleurodesis para el tratamiento del derrame pleural maligno.Materiales y Métodos: Estudio clínico, analítico, observacional, prospectivo, el cual incluyó 12 pacientes con diagnóstico clínico e histopatológico de derrame pleural maligno, a quienes se les practicó pleurodesis empleando talco estéril y yodopovidona.Resultados : Edad promedio fue de 46,25 ± 17,3 y la neoplasia primaria más común fue el cáncer de mama, representando el 50% de los casos estudiados. El grupo de pacientes tratados con yodopovidona tuvo 100% de efectividad en la fusión pleural posterior a la pleurodesis, y presentaron menos complicaciones durante el procedimiento y 24 horas posteriores al mismo con respecto al grupo tratado con talco estéril, el cual tuvo un 71,4% de efectividad y un 28,6% de falla al procedimiento; asimismo, estos últimos presentaron mayor porcentaje de complicaciones. Por otra parte, no se evidenció recidiva del derrame pleural en los 30 días de valoración posteriores al procedimiento. Estas diferencias no fueron estadísticamente significativas.Conclusiones : Ambos agentes esclerosantes fueron eficaces para lograr la fusión de las pleuras en pacientes con derrame pleural maligno, siendo el talco estéril el agente con mayor tendencia a producir complicaciones y fallo del procedimiento, en comparación a la yodopovidona(AU)

To compare the use of sterile talc versus povidone-iodine as chemical agents on pleurodesis for the treatment of malignant pleural effusion.Materials and Methods : A total of 12 patients with clinical and histopathologic diagnose of malignant pleural effusion were enrolled in a clinical, analytic, observational and prospective trial, to whom sterile talc and povidone-iodine pleurodesis was applied.Results : The mean age was 46,25 ± 17,3 and the most common primary neoplasm was breast cancer, which was present in 50% of the surveyed cases. The group of patients who received povidone-iodine had 100% of effectiveness on post-pleurodesis pleural fusion, and had fewer complications during the procedure and 24 hours afterwards vis-à-vis the group who received sterile talc powder, which had 74.4% of effectiveness and 28.6% of procedure failure; furthermore, the last mentioned had higher percentage of complications. Moreover, there was no evidence of recurrence of pleural effusion in the 30 days post-procedure assessment.Conclusions : Both sclerosant agents were efficient to accomplish pleural fusion in patients with malignant pleural effusion, with sterile talc being the agent with higher tendency to generate more complications and procedure failure compared to povidone-iodine(AU)

Lung transplantation in treatment of secondary pleuroparenchymal fibroelastosis: report of one case and literature review / 器官移植

Objective To explore the treatment strategies of pleuroparenchymal fibroelastosis (PPFE). Methods A 22-year-old male patient was complicated with PPFE after receiving chemotherapy in combination with stem cell transplantation for lymphoma. He underwent thoracoscopic left lung tongue wedge resection, bilateral pleurodesis followed by allogeneic left lung transplantation. Literature review was performed to analyze the etiology, pathogenesis, imaging features, pathological features and treatment of PPFE. Results The PPFE patient required the non-invasive ventilator for 24 h before lung transplantation. After lung transplantation, the shortness of breath and respiratory failure were cured and the quality of life was significantly improved. No eligible studies was found in the domestic database, and 26 literatures published in English were found in the international databases. Among them, 9 literatures (case reports) were finally included after screening. PPFE could be divided into the primary and secondary categories according to the etiology. The clinical manifestations of PPFE mainly included dry cough, dyspnea on exertion, chest pain, repeated pneumothorax and body weight loss. Chest CT scan demonstrated irregular thickening of the pleura in bilateral upper lungs. Pathological manifestations consisted of evident thickening of the visceral pleura, fibroelastosis and arrangement disorder in the pleura and the underlying pulmonary interstitium. PPFE could progress rapidly. Adrenocortical hormone and other immunosuppressive agents yielded low clinical efficacy and poor clinical prognosis. Lung transplantation was a necessary treatment for PPFE. Conclusions PPFE cannot be effectively treated by conservative therapy. It is recommended to deliver lung transplantation as early as possible.

Povidone-Iodine Pleurodesis for Chylothorax in an Extremely Low Birth Weight Infant

Chylothorax, the accumulation of chyle in the pleural space, is a rare condition, but can lead to serious complications in neonates. Conservative therapy for chylothorax includes enteral feeding with medium-chain triglyceride-enriched diet or parenteral nutrition and administration of octreotide. Surgical management is considered in cases where there is no response to conservative therapy; however, the standardized approach to refractory neonatal chylothorax is still controversial. Chemical pleurodesis can be used when medical therapies for chylothorax fail, to avoid more invasive surgical procedures. We report an extremely preterm infant born at 26 weeks of gestation with refractory chylothorax after patent ductus arteriosus ligation. The infant was successfully treated with pleurodesis using 4% povidone-iodine, without long-term side effects.

Results: Total of 68 patients were taken into the study. Out of all, forty nine patients (72%) achieved confirmed complete response to treatment while nine patients (13.2%) achieved partial response. Failure of treatment was seen in ten (14.7%) patients. The overall success rate was 85.2%. Conclusions: Pleurodesis with povidone iodine is a safe and effective method which can be used for chemical pleurodesis.

Neumotórax espontáneo en pediatría. Reporte de un caso y revisión de la literatura / Spontaneous pneumothorax in pediatrics. Case report and a review of the literature

El neumotórax consiste en la acumulación de aire en el espacio pleural tras un defecto en una de las pleuras. Puede ser de origen traumático o espontáneo, dividiéndose este último en primario o secundario según ausencia o presencia de enfermedad pulmonar subyacente. En pediatría tiene incidencia variable, pero es más frecuente en varones, adolescentes, de fenotipo asténico y fumadores. Se sospecha ante un cuadro de disnea de inicio súbito asociado o no a dolor torácico y se certifica el diagnóstico y extensión mediante radiografía de tórax. Suelen seguirse las recomendaciones de tratamiento establecidas en pacientes adultos debido a que no existen guías específicas para esta edad.Dependiendo de sumagnitud, las opciones terapéuticas para un primer episodio de neumotórax espontáneo varían entre el manejo conservador con observación y oxigenoterapia, la pleurotomía mínima con instalación de tubo o el manejo quirúrgico primario mediante apicectomía y pleurodesis, que se plantea especialmente ante fuga de aire persistente o recidiva. Si el manejo es conservador, existe un riesgo de recurrencia de alrededor de un 40%. Se presenta el caso de un adolescente de sexomasculino que presenta un neumotórax espontáneo primario extenso con fuga de aire persistente, por lo que semaneja con apicectomía y pleurodesis por videotoracoscopia (VATS).

A pneumothorax is an accumulation of air in the pleural space caused by a defect in the pleura. It can be traumatic or spontaneous; the latter being primary or secondary if there is underlying lung disease. Its incidence in pediatrics is variable, but it ismore common in thin, adolescent,male smokers. It is to be suspected in sudden dyspnea,with orwithout chest pain, and the diagnosis is confirmed and quantified by chest X-ray. Pediatric patients are treated in the same way as adults, there being no specific guidelines for the pathology in pediatrics. Depending on the extent of the pneumothorax, treatment may be conservative, administering oxygen and monitoring; removing the air with a chest tube through a minimal pleurotomy; or apicectomy and pleurodesis if other methods are unsuccessful. With conservative treatment there is a 40% chance of recurrence. We present the case of a male adolescent who presented with an extensive primary pneumothorax which did not resolve with conservative treatment and so was treated by video-assisted thorascopic apicoectomy and pleurodesis.

Pleurodesis in the treatment of systemic lupus erythematosus complicated with refrac-tory pleural effusion / 军事医学

Objective To investigate the effect and feasibility of pleurodesis in the treatment of systemic lupus erythematosus(SLE)complicated with refractory pleural effusion.Methods The clinical data on four patients were diagnosed with SLE complicated with refractory pleural effusion and received pleurodesis was retrospectively analyzed.At the same time,using such terms as"lupus"and"pleural effusion",we searched English literature in Pubmed and in Wan-Fang Database of China.Results A total of 7 cases with relative complete data were found from the literature.Six patients were female,and one was male.Three cases had bilateral pleural effusion,two had left pleural effusion,and two had right pleural effusion.Then,these eleven patients were analyed together.Those patients who suffered significant dyspnea were related to chronic pleural effusion.They were all treated with a large dose of corticosteroid and immunosuppressive agents before pleurodesis,but none of the therapies was valid.They had undergone frequent multiple fluid aspirations.The total aspirated volume of one patient exceeded 80 L before pleurodesis.The patients with pleurodesis were well tolerated and had no complications after operation.There was no relapse in follow-up.After pleurodesis,the pleural effusion of all the patients was completely improved.Conclusion The clinical manifestations of refractory pleural effusion are relatively rare in patients with SLE.Drug therapy has poor effect,while traditionally used pleurodesis may be safer and preferred in such cases.It can effectively improve patients′prognosis and quality of life,but due to the small number of reported patients,the best type of intervention waits to be found.

Spontaneous Regression of Metastatic Renal Cell Carcinoma after Talc Pleurodesis

Spontaneous regression of metastatic renal cell carcinoma (mRCC) was reported over the last century. However, there are no reports on spontaneous regression of mRCC by talc pleurodesis. A 43-year-old man who underwent left nephrectomy by RCC visited emergency room with headache and hallucination. Tumor was metastasized to brain, lung, and pleura accompanied by malignant pleural effusion. Talc pleurodesis by video-assisted thoracoscopic surgery was performed to treat malignant pleural effusion. After 7 months without specific chemotherapy, pulmonary lesions of mRCC gradually regressed. We thought that this phenomenon appears as an immunologic response of talc pleurodesis. We herein present a rare case of spontaneous regression of mRCC following talc pleurodesis. To the best of our knowledge, this is the first case of spontaneous regression in mRCC following talc pleurodesis.

Ultrasound-guided intrapleural positioning of pleural catheters: influence on immediate lung expansion and pleurodesis in patients with recurrent malignant pleural effusion / Posicionamento intrapleural, guiado por ultrassonografia, de cateteres pleurais: influência na expansão pulmonar imediata e na pleurodese em pacientes com derrame pleural maligno recorrente

ABSTRACT Objective: To evaluate the role of intrapleural positioning of a pleural catheter in early lung expansion and pleurodesis success in patients with recurrent malignant pleural effusion (RMPE). Methods: This was a retrospective study nested into a larger prospective cohort study including patients with RMPE recruited from a tertiary university teaching hospital between June of 2009 and September of 2014. The patients underwent pleural catheter insertion followed by bedside pleurodesis. Chest CT scans were performed twice: immediately before pleurodesis (iCT) and 30 days after pleurodesis (CT30). Catheter positioning was categorized based on iCT scans as posterolateral, anterior, fissural, and subpulmonary. We used the pleural volume on iCT scans to estimate early lung expansion and the difference between the pleural volumes on CT30 and iCT scans to evaluate radiological success of pleurodesis. Clinical pleurodesis success was defined as no need for any other pleural procedure. Results: Of the 131 eligible patients from the original study, 85 were included in this nested study (64 women; mean age: 60.74 years). Catheter tip positioning was subpulmonary in 35 patients (41%), anterior in 23 (27%), posterolateral in 17 (20%), and fissural in 10 (12%). No significant differences were found among the groups regarding early lung expansion (median residual pleural cavity = 377 mL; interquartile range: 171-722 mL; p = 0.645), radiological success of pleurodesis (median volume = 33 mL; interquartile range: −225 to 257 mL; p = 0.923), and clinical success of pleurodesis (85.8%; p = 0.676). Conclusions: Our results suggest that the position of the tip of the pleural catheter influences neither early lung expansion nor bedside pleurodesis success in patients with RMPE.

RESUMO Objetivo: Avaliar o papel do posicionamento intrapleural do cateter pleural na expansão pulmonar precoce e no sucesso da pleurodese em pacientes com derrame pleural maligno recorrente (DPMR). Métodos: Trata-se de um estudo retrospectivo aninhado em um estudo prospectivo de coorte maior com pacientes com DPMR recrutados em um hospital-escola universitário terciário entre junho de 2009 e setembro de 2014. Os pacientes foram submetidos a inserção de cateter pleural e, em seguida, pleurodese à beira do leito. A TC de tórax foi realizada duas vezes: imediatamente antes da pleurodese (TCi) e 30 dias após a pleurodese (TC30). Com base na TCi, a posição do cateter foi classificada em posterolateral, anterior, fissural e subpulmonar. Usamos o volume pleural na TCi para estimar a expansão pulmonar precoce e a diferença entre os volumes pleurais na TC30 e na TCi a fim de avaliar o sucesso radiológico da pleurodese. Considerou-se que a pleurodese teve êxito clínico quando não foi necessário realizar nenhum outro procedimento pleural. Resultados: Dos 131 pacientes elegíveis do estudo original, 85 foram incluídos neste estudo aninhado (64 mulheres; média de idade: 60,74 anos). A posição da ponta do cateter foi subpulmonar em 35 pacientes (41%), anterior em 23 (27%), posterolateral em 17 (20%) e fissural em 10 (12%). Não houve diferenças significativas entre os grupos quanto à expansão pulmonar precoce (mediana da cavidade pleural residual = 377 ml; intervalo interquartil: 171-722 ml; p = 0,645), sucesso radiológico da pleurodese (mediana do volume = 33 ml; intervalo interquartil: −225 a 257 ml; p = 0,923) e sucesso clínico da pleurodese (85,8%; p = 0,676). Conclusões: Nossos resultados sugerem que a posição da ponta do cateter pleural não influencia nem a expansão pulmonar precoce nem o sucesso da pleurodese à beira do leito em pacientes com DPMR.
