Outcome and etiology of fetal pleural effusion, fetal ascites and hydrops fetalis after fetal intervention: retrospective observational cohort from a single institution

OBJECTIVES

Non-immune hydrops fetalis (NIHF) is the pathological accumulation of fluids in fetal compartments, without maternal isoimmunization. Fetal interventions (e.g. shunting, fetal paracentesis, fetal thoracocentesis, fetal pleurodesis) are used to alleviate fluid accumulations, but the outcome is uncertain because the underlying causes of NIHF vary. We aimed to explore the etiology and long-term outcome of NIHF after fetal intervention.

METHODS

This was a retrospective review of fetuses with NIHF, defined by the presence of fetal ascites, pleural or pericardial effusion, skin edema or cystic hygroma, or a combination of these features, who underwent intervention at our institution during the period 2012-2021. Clinical surveillance, genetic analysis and viral infection screening were used to define the etiology. Chart reviews and telephone interviews were conducted to assess the long-term outcomes.

RESULTS

In total, 55 fetuses were enrolled and 46 cases had final follow-up data after delivery. Etiology was identified in 33 cases, including four for which the underlying causes were not identified initially using small-gene-panel tests but which were later diagnosed with monogenic disorders by whole-exome sequencing (WES). Twenty-three cases with follow-up survived, having a follow-up period of 2-11 years at the time of writing, of which 17 were healthy. All 11 cases initially presenting as congenital chylothorax survived with favorable outcome.

CONCLUSIONS

The etiologies of NIHF are heterogeneous, and the long-term (spanning 2-11 years) outcome of fetal intervention varies, according to the underlying etiology, with cases caused by congenital chylothorax having the best prognosis. Genome-wide tests, such as WES, may be helpful in determining the underlying condition in cases caused by a genetic disorder, and this may affect fetal therapy approaches in the future. © 2023 International Society of Ultrasound in Obstetrics and Gynecology.

Post-traumatic pleural effusion: Don't forget the chylothorax!

In this case we describe a 58-year-old male with bilateral pleural effusion after a blunt trauma to the back. A pleural puncture revealed a chylothorax. An additional computed tomography scan showed a vertebral fracture at level D8 with rupture of the nearby thoracic duct. Our patient could be treated with a conservative approach. This case highlights the importance of ruling out a chylothorax in any post-traumatic pleural effusion. Despite the low prevalence, we consider it a don't-miss diagnosis given the specific treatment requirements.

Pleural procedures: an audit of practice and complications in a regional Australian teaching hospital

BACKGROUND

Pleural procedures are essential for the investigation and management of pleural disease and can be associated with significant morbidity and mortality. There is a lack of pleural procedure complication data in the Australian and New Zealand region.

AIMS

To review pleural procedure practices at Wollongong Hospital with an emphasis on the assessment of complications, use of thoracic ultrasound (TUS), pathology results and comparison of findings with international data.

METHODS

Retrospective analysis of medical records was performed on pleural procedures identified through respiratory specialist trainee logbooks at Wollongong Hospital from January 2018 to December 2021. Comparison of complication rates was made to the British Thoracic Society 2011 a national pleural audit.

RESULTS

One hundred and twenty-one pleural procedures were identified. There were 71 chest drains, 49 thoracocentesis and one indwelling pleural catheter (IPC) insertion. Ninety-seven per cent of procedures were performed for pleural effusions and 3% for pneumothorax. This audit demonstrated a complication rate (excluding pain) of 16.9% for chest drains and 4.1% for thoracocentesis. This gave an overall complication event rate of 10.8% (excluding pain) for pleural procedures. There was no major bleeding, organ puncture, pleural space infection or death. Bedside TUS was used in 99% of procedures.

CONCLUSION

Complication rates for pleural procedures performed by respiratory specialist trainees at Wollongong Hospital are comparable with international outcomes. This audit provides data for comparison on pleural procedure complication rates in Australia. Future studies are required to determine complication rates with IPCs.

Which Role for Muscle-Sparing Posterolateral Thoracotomy in the Treatment of Spontaneous Pneumothorax?

Objective  This study aims to show the place of muscle-sparing posterolateral thoracotomy in the treatment of spontaneous pneumothorax. Methods  It was a single-center study performed in the Department of Thoracic Surgery of Teaching hospital Hassan II of Fez for 8 years. We adopted the nosological definition, which classifies spontaneous pneumothorax into three categories. We included patients over 15 years of age with primary or secondary spontaneous pneumothorax operated by posterolateral thoracotomy without muscle section, and we analyzed the specific indications of this approach. It included 49 patients with primary or secondary spontaneous pneumothorax, operated by muscle-sparing posterolateral thoracotomy. Data were collected from regularly updated computer files of patients, entered by Excel 2013, and analyzed using SPSS.20 software. These data are: epidemiological, clinical, radiological, surgical exploration, surgical procedure, the result of the surgery and the evolution. Results  The average age was 42 years. Smoking was found in 61% of cases and pulmonary tuberculosis in 10% of cases. Thoracic computed tomography (CT) showed bullae and blebs in 31% of cases, pleural adhesions and pachypleuritis in 50% of cases, and hydropneumothorax with pachypleuritis in 37% of cases. There is a statistical correlation between pleuropulmonary decortication and pachypleuritis ( p  = 0.002) or hydropneumothorax ( p  = 0.001) on CT. Bullae and blebs resection was performed in 53% of cases and pleuropulmonary decortication in 63% of cases. A right pleuropneumonectomy was performed in one case. The follow-up was uneventful in 82% of cases. Conclusion  Muscle-sparing posterolateral thoracotomy remains the best approach and leads to good results.

Brucella pleuritis misdiagnosed as tuberculous pleuritis: a case report

Pleurisy and pleural effusion caused by Brucella infection are rare. However, clinicians lack an understanding of these possibilities, and the underlying disorder is easy to misdiagnose. We report a 52-year-old male farmer who was admitted to hospital with a fever, chest pain, and shortness of breath. Closed chest drainage was performed by thoracocentesis, and the concentration of adenosine deaminase (ADA) in the pleural fluid was >45 U/L. Mononuclear cells in the pleural fluid accounted for 90% of the cells, and pathology indicated a large number of lymphocytes. The clinical diagnosis was tuberculosis with tuberculous pleurisy. However, subsequent pleural fluid culture results did not support tuberculous pleurisy. The results of pleural fluid culture indicated Brucella, and the results of Brucella tiger red plate agglutination indicated a titer of 1:400 (+++). The final diagnosis was brucellosis with pneumonia and pleurisy. After 12 weeks of oral treatment, the patient underwent follow-up chest radiographs. Radiography indicated complete resolution of the hydrothorax and pneumonia, and the patient reported no discomfort. The short-term curative effect was excellent. Pleurisy associated with brucellosis should be considered a differential for pleurisy in regions where brucellosis is endemic, to minimize the risk of misdiagnosis.

Recurrent pleural effusion from ovarian hemangioma: A rare pseudo-Meigs syndrome presentation

Pleural effusion is a common condition related to various diseases such as heart failure, malignancies, and pneumonia. Ovarian hemangioma is a rare type of female genital tumour and can rarely cause pleural effusion. In this case, we present a 48-year-old female with repeated episodes of recurrent right-sided pleural effusion over 1 year with no clear aetiology. Abdominal computed tomography revealed a large left ovarian mass. After surgical removal of the mass, the repeated pleural effusion episodes ceased, and histopathology analysis reported a rare ovarian hemangioma. Pseudo Meigs' syndrome is a triad of an ovarian tumour, ascites, and hydrothorax that rarely presents with ovarian hemangioma; both effusions are eradicated after removing the tumour.

Pleural manometry during thoracocentesis in patients with malignant pleural effusion: A randomized controlled trial

Background

Large-volume therapeutic thoracocentesis may be associated with pulmonary congestion or a more serious complication; re-expansion pulmonary edema (RPE). We investigated whether monitoring pleural pressure with manometry during thoracocentesis would prevent these pulmonary symptoms/RPE and allow larger volume drainage.

Methods

We did a randomized controlled trial involving 110 patients with large malignant pleural effusions. Patients were randomly allocated to obtain thoracocentesis with or without pleural manometry. We measured the incidence of pulmonary congestion symptoms, total fluid aspirated, and pleural pressures in both groups. This trial is listed on ClinicalTrials.gov as NCT04420663.

Results

The mean amount of total thoracocentesis fluid withdrawn from the control group was 945.4±78.9 (mL) and 1690.9±681.0 (mL) from the intervention group (P<0.001). Clinical symptoms of pulmonary congestion appeared in (n=20) (36.3%) of patients in the intervention group while no symptoms appeared in controls (P<0.001). The difference between opening and closing pressures between the non-symptomatic cluster and the symptomatic cluster was (32.8±15.6 versus 42.2±13) respectively (P=0.02). Total fluid withdrawn from the non-symptomatic cluster was 1828.5±505 mL in comparison to 1,450±875 mL in the symptomatic cluster (P=0.04).

Conclusion

Pleural manometry can be used to increase the volume of fluid removed on each occasion in patients with malignant pleural effusion. In our study, pleural manometry was associated with a larger number of pulmonary congestion symptoms/RPE. We believe that manometry may be a useful tool to not exceed a 17 cm H2O gradient in pleural pressure which should be avoided to prevent pulmonary congestion symptoms or RPE. Pulmonary congestion symptoms/RPE are not related to the amount of volume withdrawn but to the gradient of pleural pressure drop. Our conclusion does support the adoption of pleural manometry whenever large-volume thoracocentesis is intended.

A Single-Center Experience on the Treatment Outcomes of Patients with COVID-19-Pleural Disorders: Lessons for the Future

Background

Pleural disorders in novel coronavirus disease 2019 (COVID-19), responsible for the deaths of more than 6.7 million people worldwide, are relatively uncommon and underappreciated findings. The severity of the pleural disease in these patients correlates with the treatment outcome and overall prognosis.

Objective

We aim to review our experience with treatment modalities and prognosis in 45 patients with COVID-19, who were treated at our Clinic between April 2020 and October 2021.

Methods

We conducted a retrospective, single-center, cross-sectional study. Demographic data, the type of thoracosurgical intervention(s), and treatment outcome for 45 patients included in this study were recorded for every patient. We analyzed the type and number of treatment modalities according to the pleural disorder, and the outcome of the treatment.

Results

Pneumothorax was the most common COVID-19-related pleural disorder, followed by the pleural effusion. Tube thoracostomy was the mainstay of treatment, performed in 84.4% of patients with unilateral pleural complications. In total, 20% of our patients were on mechanical ventilation, and all of them had a fatal outcome. We found statistical significance in comparison to the percentage of fatal outcomes between patients treated with and without mechanical ventilation (p=0.000).

Conclusion

COVID-19-related pleural disorders are prognostic markers of disease progression. Mechanically ventilated patients who require tube thoracostomy have an unfavorable prognosis.

A fetus with large mediastinal cystic lymphatic malformation managed with prenatal serial thoracocentesis and postnatal sclerotherapy

We report a very rare case of large fetal mediastinal cystic lymphatic malformation (cLM), formerly called lymphangioma, that was managed with prenatal serial thoracocentesis and postnatal sclerotherapy. A fetal pericardial effusion-like lesion gradually increased the size until it occupied more than half of the thoracic cavity. Thoracocentesis was performed three times, namely at 31 and 35 weeks of gestation, and also just before the delivery for decompression. The characteristic shape changes of the lesion were observed after thoracocentesis. A boy delivered by planned cesarian section at term required respiratory support after birth. Postnatal magnetic resonance imaging (MRI), which showed a large cystic lesion with septa and hemorrhage without solid components, led to the diagnosis of cLM. The fluid from the cyst continued to be drained. Neonatal sclerotherapy using OK-432 was effective and the infant recovered well. Fetal thoracocentesis may be useful for the diagnosis and management of a large mediastinal cLM.

Pseudo-pheochromocytoma due to obstructive sleep apnea: a case report

SUMMARY

Obstructive sleep apnea (OSA) is a condition of intermittent nocturnal upper airway obstruction. OSA increases sympathetic drive which may result in clinical and biochemical features suggestive of pheochromocytoma. We present the case of a 65-year-old male with a 2.9-cm left adrenal incidentaloma on CT, hypertension, symptoms of headache, anxiety and diaphoresis, and persistently elevated 24-h urine norepinephrine (initially 818 nmol/day (89-470)) and normetanephrine (initially 11.2 µmol/day (0.6-2.7)). He was started on prazosin and underwent left adrenalectomy. Pathology revealed an adrenal corticoadenoma with no evidence of pheochromocytoma. Over the next 2 years, urine norepinephrine and normetanephrine remained significantly elevated with no MIBG avid disease. Years later, he was diagnosed with severe OSA and treated with continuous positive airway pressure. Urine testing done once OSA was well controlled revealed complete normalization of urine norepinephrine and normetanephrine with substantial symptom improvement. It was concluded that the patient never had a pheochromocytoma but rather an adrenal adenoma with biochemistry and symptoms suggestive of pheochromocytoma due to untreated severe OSA. Pseudo-pheochromocytoma is a rare presentation of OSA and should be considered on the differential of elevated urine catecholamines and metanephrines in the right clinical setting.

LEARNING POINTS

Obstructive sleep apnea (OSA) is a common condition among adults. OSA may rarely present as pseudo-pheochromocytoma with symptoms of pallor, palpitations, perspiration, headache, or anxiety. OSA should be considered on the differential of elevated urine catecholamines and metanephrines, especially in patients with negative metaiodobenzylguanidine (MIBG) scan results.

Modern day management of a unilateral pleural effusion

Over 50 systemic conditions may affect the pleura and, thus, unilateral pleural effusions may present for a variety of reasons. Investigating the cause is essential to providing appropriate management. Various pleural interventions are available in current practice, but have varying diagnostic sensitivity. It is, therefore, vital to consider the intervention with the highest diagnostic yield appropriate to the particular clinical situation. The diagnostic pathway in unilateral pleural effusion is increasingly outpatient based, avoiding hospitalisation, which is particularly relevant with the recent COVID-19 pandemic.

Neonatal Hydrops Simulation Model: A Technical Report

This technical report describes the creation of a model of a newborn with hydrops fetalis (HF). This model is easy to assemble, quite authentic and reusable allowing for many neonatal intensive care providers to practice rare, life-saving procedures. Learning objectives and a critical action checklist have been included to guide the simulation and add additional complexity to the scenario, if desired.

Clinical profile and outcome of neonatal pneumothorax in resource-limited neonatal intensive care unit

OBJECTIVE OF STUDY

To determine the frequency, clinical profile, and outcome of pneumothoraxes in neonates in resource-limited neonatal intensive care unit (NICU) setting.

STUDY DESIGN

Prospective cohort.

PLACE AND DURATION OF STUDY

The study was carried over a period of 4 years and 6 months at two NICUs of Combined Military Hospital (CMH) Multan (January 2011-August 2013) and CMH Abbottabad (September 2013-July 2015).

MATERIALS AND METHODS

All neonates fulfilling inclusion criteria were included in the study. Demographic and clinical parameters were recorded. All stable cases were initially managed on headbox oxygen, nasal oxygen, or improvised bubble continuous positive airway pressure devices (B-CPAP). In suspected cases, pneumothorax was confirmed on a portable chest X-Ray (CXR). Hemodynamically stable neonates were closely observed for spontaneous resolution whereas unstable neonates were managed by needle thoracocentesis or thoracostomy with or without ventilator support. End point of the study was either discharge or death of the neonate.

RESULTS

Of a total of 1427 included neonates, 66 (4.6%) developed pneumothorax. Pneumothorax was more common in late pre-term and term infants with normal birth weight (>2.5 kg). Primary diseases leading to pneumothorax were respiratory distress syndrome (RDS) 38 (57.6%), meconium aspiration syndrome (MAS) 10 (15.2%), transient tachypnea of newborn (TTN) 9 (13.6%), birth asphyxia syndrome (BAS) 6 (9.1%), and pneumonia 3 (4.5%). Majority of the patients 58 (87.9%), required thoracostomy, 2 (3%) required only needle thoracocentesis while spontaneous resolution occurred in 6 (9.1%) patients. Out of 66 patients, 48 (72.7%) were discharged and 18 (27.3%) died. Average hospital stay was 10.5 ± 5.85 days.

CONCLUSION

Pneumothorax is not an uncommon complication in neonates presenting with respiratory distress in resource-limited NICUs. High index of suspicion is required for early recognition and timely management, as delay is associated with significant mortality.

Development of a Synthetic Training Model for Canine Thoracocentesis

Thoracocentesis, a procedure in which air or fluid is removed from the pleural space, is used to relieve respiratory distress, and as a diagnostic procedure in human and veterinary medicine. Veterinary students commonly learn and practice the procedure on canine cadavers which are in limited supply and are not amenable to long-term storage and use. Practicing thoracocentesis on a cadaveric model also provides limited feedback indicative of success and/or procedural complications. One commercial model for practicing canine thoracocentesis is available, but it costs over US$2000 and is excessively bulky. In order to improve the learning process for veterinary students, we have developed a reusable synthetic canine thorax model that accurately replicates the thoracocentesis procedure, provides immediate feedback to the students and reduces the need for canine cadavers. The low cost of our product provides an efficient alternative to cadavers for instruction in veterinary schools or hospitals.

Acute Hemothorax Causing Hemorrhagic Shock Following Small-bore Thoracocentesis in a Patient on Clopidogrel: A Case Report and Literature Review

Clopidogrel is one of the most commonly prescribed thienopyridines used postcoronary stenting for acute coronary syndrome (ACS). There have been several concerns regarding performing small-bore thoracocentesis on patients on clopidogrel in our practice. We present an 85-year-old male with a history of diabetes, atrial fibrillation, diastolic heart failure, chronic kidney disease (CKD) stage three, who recently had a non-ST elevation myocardial infarction (NSTEMI) requiring a drug-eluting stent (DES) to the left anterior descending (LAD) artery, and was on dual anti-platelet therapy (DAPT). He was admitted with worsening shortness of breath and found to have bilateral pleural effusions. He required several small-bore, ultrasound-guided thoracocentesis on the right side while on clopidogrel. Intensivists or residents did all the procedures. The patient went into a hemorrhagic shock following his third small-bore thoracocentesis, requiring pressors, blood and platelet transfusions, and a surgical intercostal (IC) drain insertion. He eventually became clinically stable. An IC arteriogram within 24 h ruled out IC artery injury. Healthcare professionals perceive small-bore thoracocentesis as a safe procedure done on medical, surgical, intensive care, and interventional radiology (IR) units. The overall consensus is that it is safe to perform it on patients taking clopidogrel. We emphasize through this case report the bleeding risks associated with performing such procedures on patients while on clopidogrel and considering holding clopidogrel when feasible or bridging with an intravenous anti-platelet drug.

Ratio of carcinoembryonic antigen in pleural fluid and serum for the diagnosis of malignant pleural effusion

Background

Tumour markers in pleural fluid and their diagnostic value are subject to debate. Although there are several studies on this topic, standardized cut-off values do not exist. In this study we investigated the potential of a ratio of carcinoembryonic antigen (CEA) in pleural fluid and serum, serving as an individual marker for pleural cancer manifestation.

Methods

A total of 201 consecutive patients with unclear pleural effusion were included in the study; 98 were diagnosed with malignant pleural effusion and 103 had an effusion due to other, benign reasons. CEA levels in pleural fluid and serum were measured.

Results

By using receiver operating characteristics analysis, at the cut-off of 1.0, the CEA ratio showed a specificity of 92% and sensitivity of 85%, with a positive predictive value of 91% and a negative predictive value of 87%. These results are higher than in previous investigations on different pleural tumour markers and their combination.

Conclusions

The CEA ratio is a useful tool in predicting pleural carcinosis. Elevated results in cytology-negative patients should lead to further investigations, such as repeated cytological examination or thoracoscopy.

Pleural Tap-Guided Antimicrobial Treatment for Pneumonia with Parapneumonic Effusion or Pleural Empyema in Children: A Single-Center Cohort Study

Parapneumonic effusion or pleural empyema (PPE/PE) is a frequent complication of community-acquired pneumonia (CAP) in children. Different management approaches exist for this condition. We evaluated a 14-day treatment with amoxicillin (AMX) with/without clavulanic acid (AMC) confirmed or modified by microbiological findings from pleural tap. Children ≤16 years of age with radiologically diagnosed PPE/PE and initial diagnostic pleural tap were included at University Children’s Hospital Zurich from 2001–2015. AMX/AMC was given for 14 days and rationalized according to microbiological pleural tap results. Clinical and radiological follow-up was scheduled until six months or full recovery. In 114 of 147 (78%) children with PPE/PE a pathogen was identified by culture, polymerase chain reaction (PCR), and/or antigen testing. Streptococcus pneumoniae was detected in 90 (79%), S. pyogenes in 13 (11%), and Staphylococcus aureus in seven cases (6%), all but two cultured pathogens (96%) were sensitive to AMX/AMC. One-hundred two of 147 (69%) patients received treatment with AMX/AMC for 14 days. They recovered more rapidly than patients with a different management (p = 0.026). Of 139 children with follow-up, 134 (96%) patients fully recovered. In conclusion, 14-day AMX/AMC treatment confirmed and rarely modified by microbiological findings from pleural tap resulted in full recovery in >95% of children with PPE/PE.

Characteristic pattern of pleural effusion in electrical impedance tomography images of critically ill patients

BACKGROUND

Electrical impedance tomography (EIT) is increasingly used for continuous monitoring of ventilation in intensive care patients. Clinical observations in patients with pleural effusion show an increase in out-of-phase impedance changes. We hypothesised that out-of-phase impedance changes are a typical EIT finding in patients with pleural effusion and could be useful in its detection.

METHODS

We conducted a prospective observational study in intensive care unit patients with and without pleural effusion. In patients with pleural effusion, EIT data were recorded before, during, and after unilateral drainage of pleural effusion. In patients with no pleural effusion, EIT data were recorded without any intervention. EIT images were separated into four quadrants of equal size. We analysed the sum of out-of-phase impedance changes in the affected quadrant in patients with pleural effusion before, during, and after drainage and compared it with the sum of out-of-phase impedance changes in the dorsal quadrants of patients without pleural effusion.

RESULTS

We included 20 patients with pleural effusion and 10 patients without pleural effusion. The median sum of out-of-phase impedance changes was 70 (interquartile range 49-119) arbitrary units (a.u.) in patients with pleural effusion before drainage, 25 (12-46) a.u. after drainage (P<0.0001) and 11 (6-17) a.u. in patients without pleural effusion (P<0.0001 vs pleural effusion before drainage). The area under the receiver operating characteristics curve was 0.96 (95% limits of agreement 0.91-1.01) between patients with pleural effusion before drainage and those without pleural effusion.

CONCLUSIONS

In patients monitored with EIT, the presence of out-of-phase impedance changes is highly suspicious of pleural effusion and should trigger further examination.

Complication of diagnostic pleural aspiration: is it of value in hemodialysis patients?

Pleural effusions are common in hemodialysis patients and are associated with significant morbidity. Diagnostic pleural aspiration and subsequent biochemical analysis can be used to differentiate exudates and transudates. In particular, Light's criteria have been validated in the general population although their efficacy in hemodialysis patients is unclear. Furthermore, aspiration is not without risk; we report the case of a life-threatening thoracic bleed as a complication of diagnostic thoracocentesis in a hemodialysis patient, in whom a transudative effusion was misclassified according to Light's criteria. Retrospective examination of a further 22 aspirations in hemodialysis patients suggests that biochemical analysis of pleural fluid in this group is of limited value. Careful clinical and radiological assessment may be of greater value in determining individuals who may benefit from formal drainage, rather than diagnostic aspiration with its attendant risks.

Pleural effusion: diagnosis, treatment, and management

A pleural effusion is an excessive accumulation of fluid in the pleural space. It can pose a diagnostic dilemma to the treating physician because it may be related to disorders of the lung or pleura, or to a systemic disorder. Patients most commonly present with dyspnea, initially on exertion, predominantly dry cough, and pleuritic chest pain. To treat pleural effusion appropriately, it is important to determine its etiology. However, the etiology of pleural effusion remains unclear in nearly 20% of cases. Thoracocentesis should be performed for new and unexplained pleural effusions. Laboratory testing helps to distinguish pleural fluid transudate from an exudate. The diagnostic evaluation of pleural effusion includes chemical and microbiological studies, as well as cytological analysis, which can provide further information about the etiology of the disease process. Immunohistochemistry provides increased diagnostic accuracy. Transudative effusions are usually managed by treating the underlying medical disorder. However, a large, refractory pleural effusion, whether a transudate or exudate, must be drained to provide symptomatic relief. Management of exudative effusion depends on the underlying etiology of the effusion. Malignant effusions are usually drained to palliate symptoms and may require pleurodesis to prevent recurrence. Pleural biopsy is recommended for evaluation and exclusion of various etiologies, such as tuberculosis or malignant disease. Percutaneous closed pleural biopsy is easiest to perform, the least expensive, with minimal complications, and should be used routinely. Empyemas need to be treated with appropriate antibiotics and intercostal drainage. Surgery may be needed in selected cases where drainage procedure fails to produce improvement or to restore lung function and for closure of bronchopleural fistula.

Empyema thoracis: Surgical management in children

Empyema thoracis can produce significant morbidity in children if inadequately treated. Correct evaluation of the stage of the disease, the clinical condition of the child and proper assessment of the response to conservative treatment is crucial in deciding the mode of further surgical intervention. This ranges from intercostal chest tube drainage and video-assisted thoracoscopic surgery to open decortication. Surgical decortication becomes mandatory in neglected cases; it gives very gratifying results ameliorating the disease rapidly and is well tolerated by young patients. This article reviews the current literature and discusses the important considerations while managing these patients. Indications for surgery are highlighted, based on our large experience at a tertiary care center.
