ABSTRACT

Bronchopulmonary fistula (BPF) is an abnormal connection between the pleural space and bronchial tree, potentially leading to fatal outcomes if untreated. While BPF commonly arises following lung surgery, it can also be linked to infections. This report details the case of a 47-year-old male with recent untreated bacterial pneumonia, who developed bilateral pneumothoraces with persistent air leaks, Pseudomonas and Aspergillus empyema, culminating in a right-sided BPF necessitating video-assisted thoracic surgery (VATS) decortication. The agenda of this presentation is to enhance early recognition of BPF, which can be presented subtly, to avert severe complications.

ABSTRACT

Pleural empyema can lead to significant morbidity and mortality despite chest drainage and antibiotic treatment, necessitating novel and minimally invasive interventions. Fusobacterium nucleatum is an obligate anaerobe found in the human oral and gut microbiota. Advances in sequencing and puncture techniques have made it common to detect anaerobic bacteria in empyema cases. In this report, we describe the case of a 65-year-old man with hypertension who presented with a left-sided encapsulated pleural effusion. Initial fluid analysis using metagenomic next-generation sequencing (mNGS) revealed the presence of Fusobacterium nucleatum and Aspergillus chevalieri. Unfortunately, the patient experienced worsening pleural effusion despite drainage and antimicrobial therapy. Ultimately, successful treatment was achieved through intrapleural metronidazole therapy in conjunction with systemic antibiotics. The present case showed that intrapleural antibiotic therapy is a promising measure for pleural empyema.

ABSTRACT

Background: While ample high-level evidence supports the limited use of antibiotics post-source control in intraabdominal infections, there is a paucity of available data in guiding antibiotic duration for intrathoracic infections. This study aims to analyze patient outcomes among those who have undergone surgical decortication for parapneumonic pleural empyema, comparing cases managed with infectious disease (ID) specialists against those without, and to identify predictive factors influencing antibiotic duration post-source control. We hypothesized that antibiotic duration would vary depending on the involvement of ID specialists. Methods: A retrospective chart review was completed on patients with parapneumonic pleural empyemas who underwent surgical decortication at a single tertiary center from January 2011 to March 2021. Differences in patient characteristics and outcomes for those whose antibiotics were managed by ID or not were compared with Wilcoxon two-sample tests and Fisher's exact tests. Linear regression was used to evaluate for significant factors predictive of antibiotic duration. Results: A total of 116 patients underwent surgical decortication for pleural empyema of parapneumonic etiology. ID specialists were involved with antibiotic management in 62 (53.4%) cases, while the remaining cases were not managed by ID. Demographics and patient comorbidities were similar between both groups. Growth of preoperative fluid cultures was higher in patients managed by ID (40.3% vs. 20.4%, P=0.03). Postoperatively, patients managed by ID had longer durations of antibiotics (28.7 vs. 20.9 days, P<0.001) and were more likely to be on IV antibiotics than patients not managed by ID (59.7% vs. 38.9%, P=0.04). However, postoperative outcomes were similar, including rates of disease recurrence, readmission, and 30-day mortality. Linear regression revealed length of antibiotics was significantly dependent on preoperative ventilator status [estimate: 16.346; 95% confidence interval (CI): 6.365-26.326; P=0.002], growth of preoperative pleural fluid cultures (estimate: 10.203; 95% CI: 2.502-17.904; P=0.01), and ID involvement (estimate: 8.097; 95% CI: 1.003-15.191; P=0.03). Conclusions: Antibiotic duration for pleural empyema managed with surgical decortication is significantly dependent on ID involvement, preoperative growth of cultures, and preoperative ventilator status. However, outcomes, including disease recurrence and 30-day mortality, were similar between patients regardless of ID involvement and longer length of antibiotics, raising the question of what the adequate duration of antibiotics is for patients who receive appropriate source control for pleural empyema. Further study with randomized control trials should be conducted to provide high-level evidence regarding length of antibiotics in this patient population.

ABSTRACT

Introduction: Empyema is a known complication of severe pleuropneumonia. In rare cases, if poorly treated, it could result in dissemination and fistulization and transformation into empyema necessitans. The manifestation may appear as a superficial abscess. However, as management highly differs, the recognition of potentially severe phenomenon is required. Case Presentation: We describe a case of empyema necessitans on a 4-year-old girl secondary to methicillin-resistant Staphylococcus aureus. It represents the sixth pediatric case reported in the literature. It was managed by open drainage and prolonged antibiotherapy. The outcome was favorable as guidelines were extracted from similar reported cases. Conclusion: Empyema necessitans remains a rare complication with significant morbidity. Prompt diagnosis and adapted management have relied on limited literature. As such, further reports are necessary to establish proper guidelines.

ABSTRACT

OBJECTIVES: Although intrapleural administration of fibrinolytics is an important treatment option for the management of empyema, the addition of fibrinolytics failed to reduce the need for surgery and mortality in previous randomized controlled trials. This study aimed to investigate the effect of administrating fibrinolytics in the early phase (within 3 days of chest tube insertion) of empyema compared with late administration or no administration. METHODS: We used the Japanese Diagnosis Procedure Combination inpatient database to identify patients aged ≥ 16 years who were hospitalized and underwent chest tube drainage for empyema. A 1:2 propensity score matching and stabilized inverse probability of treatment weighting were conducted. RESULTS: Among the 16,265 eligible patients, 3,082 and 13,183 patients were categorized into the early and control group, respectively. The proportion of patients who underwent surgery was significantly lower in the early fibrinolytics group than in the control group; the odds ratio (95% confidence interval) was 0.69 (0.54-0.88) in the propensity score matching (P = 0.003) and 0.64 (0.50-0.80) in the stabilized inverse probability of treatment weighting analysis (P < 0.001). All-cause 30-day in-hospital mortality, length of hospital stay, duration of chest tube drainage, and total hospitalization costs were also more favorable in the early fibrinolytic group. CONCLUSIONS: The early administration of fibrinolytics may reduce the need for surgery and death in adult patients with empyema.

ABSTRACT

Purpose: The prognostic performance of urea-to-albumin ratio (UAR) has been assessed in various pulmonary and nonpulmonary conditions, but never in thoracic empyema. Therefore, our aim was to determine whether this marker has the ability to predict outcome in such patients. Methods: A single-center retrospective study was conducted in a Clinic of Thoracic Surgery at a University Hospital between January 2021 and October 2023. A total of 84 patients who underwent emergency surgery due to thoracic empyema were involved. Serum levels of urea and albumin at admission were used to calculate UAR. We analyzed area under receiver operating characteristics (AUROC) curves of UAR, systemic inflammatory response syndrome (SIRS) and quick-sequential organ failure assessment (qSOFA), and compared their prognostic performance. Results: The identified in-hospital mortality was 10.7%. The UAR showed the best ability to prognosticate mortality compared to qSOFA (AUROC = 0.828 vs 0.747) and SIRS (AUROC = 0.828 vs 0.676). We established a sensitivity of 87.5% and specificity of 74.2% at optimal cut-off value UAR > 51.1 for prediction of adverse outcome. Conclusion: In patients with thoracic empyema urea-to-albumin ratio showed significant prognostic performance and a potential for clinical application as a low cost and widely available predictor of death.

ABSTRACT

Objectives: The clinical significance of bacteremia in patients with complicated pleural infection is still uncertain. We aimed to examine the incidence and clinical significance of bacteremia in patients with complicated pleural infection. Methods: This retrospective study comprised of consecutive patients who received pleural drainage due to complicated parapneumonic effusion or empyema. The clinical, laboratory, and radiologic data and clinical outcome were compared between patients with and without bacteremia. Additionally, the factors associated with overall mortality were evaluated in these patients. Results: Of 341 patients included in the analysis, 25 (7 %) had a positive blood culture. Blood culture testing added 2 % identification of causative pathogen compared to pleural fluid culture alone. By multivariable analysis, radiologic features of cavitary lesion, a RAPID score≥5, and a positive microbial culture in pleural fluid were independently associated with bacteremia. Despite these clinical distinctions, there was ultimately no significant difference in in-hospital mortality between patients with and without bacteremia (3 vs. 4 %, p=1.0). The only factor significantly associated with overall mortality among patients with complicated pleural infections was a higher RAPID score [HR=1.96 (95 % CI=1.35-2.84)]. Conclusions: The rate of bacteremia in patients with complicated pleural infection was 7 %. Blood culture testing demonstrated limited diagnostic yield and had minimal impact on clinical outcomes compared to pleural fluid culture. Therefore, it seems that blood culture testing is more advantageous for specific patients with suspected pleural infection who have cavitary lesions or a RAPID score≥5.

ABSTRACT

We report a patient with fever and cough for 2 months who was finally given a diagnosis of alveolar-pleural fistula due to aspergillus empyema. We successfully closed the alveolar-pleural fistula with a ventricular septal defect occluder through bronchoscopy. Endoscopic closure of an alveolar-pleural fistula with ventricular septal defect occluder is worth being explored.

ABSTRACT

Introduction: Intracranial empyema is a rare but serious and life-threatening infection. It is an accumulation of purulent material in the subdural or extradural space leading to development of subdural empyema or intracranial epidural abscess, respectively. The incidence of morbidity and mortality is high because the diagnosis is often unsuspected. Infections of dental origin could be responsible for such condition. Case reports: A 22-year-old female and 30-year-old male patients, both with no significant medical history, presented with subdural empyema and intracranial epidural abscess, respectively, both complicating pan-sinusitis of dental origin. Successful outcomes were achieved with surgical drainage of the lesions, antibiotic therapy, and extraction of affected teeth. Female patient underwent further management for neurological sequelae, while male patient was discharged without neurological complications. Discussion: Intracranial suppuration of odontogenic origin is an uncommon but extremely serious complication. The most common dental origins are caries with periapical involvement and periodontitis. Wisdom tooth extraction is the most common preceding dental procedure for this infection. A multidisciplinary approach is essential for the identification and treatment of suspected oral sources. Antibiotic therapy with surgical approach is the gold standard treatment. Conclusion: This sequel to odontogenic infection is quite rare, but it can be prevented by a good oral hygiene and removal of abscessed teeth.

ABSTRACT

Background: Intrathecal baclofen infusing pumps are nowadays commonly implanted in patients suffering from severe, intractable spasticity with a background of multiple sclerosis. Although intrathecal baclofen therapy is considered a safe therapeutic modality, complications are unavoidable and broadly categorized as mechanical and infectious. In the instance of a pump pocket infection, a surgical explanation of the pump is often necessary to treat the infection. Case Description: We present the rare case of a 60-year-old woman who was admitted emergently to our clinic with a subcutaneous pump pocket empyema caused by proximal vesicocutaneous fistulas. The patient underwent explantation of the pump and otherwise had an uncomplicated perioperative course. Conclusion: The surgical explanation of the baclofen pump and antibiotic treatment were sufficient to treat the pump pocket empyema in this instance. To the best of our knowledge, this is the first report of a pump pocket empyema formed in the proximity of a vesicocutaneous fistula.

ABSTRACT

Clostridium perfringens bacteremia arises due to skin inoculation from the external environment or translocation from the gastrointestinal tract. In the event of bacteremia, it tends to colonize in anaerobic environments due to its obligatory anaerobic nature. Its inoculation in the lung, albeit rare, can occur if an anaerobic nidus is created. In the presented case, the patient developed C. perfringens bacteremia andempyema in the area of lung necrosis caused by acute pulmonary embolism. He did not have any history of chest trauma, and the source of bacteremia was deemed to be via gut translocation. The patient was noted to have multiple gastric ulcers on endoscopy and jejunal wall thickening, which likely led to the bacterial translocation into the bloodstream. He underwent video-assisted thoracoscopic surgery-assisted decortication and intravenous antibiotics, eventually leading to clinical improvement. To identify the source of Clostridium in the absence of penetrating trauma, a thorough gastrointestinal evaluation, including a colonoscopy, is warranted to identify the pathology leading to the gastrointestinal translocation.

ABSTRACT

Pleural effusions are categorized as transudative or exudative, with transudative effusions usually reflecting the sequala of a systemic etiology and exudative effusions usually resulting from a process localized to the pleura. Common causes of transudative pleural effusions include congestive heart failure, cirrhosis, and renal failure, whereas exudative effusions are typically due to infection, malignancy, or autoimmune disorders. This document summarizes appropriateness guidelines for imaging in four common clinical scenarios in patients with known or suspected pleural effusion or pleural disease. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision process support the systematic analysis of the medical literature from peer reviewed journals. Established methodology principles such as Grading of Recommendations Assessment, Development, and Evaluation or GRADE are adapted to evaluate the evidence. The RAND/UCLA Appropriateness Method User Manual provides the methodology to determine the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where peer reviewed literature is lacking or equivocal, experts may be the primary evidentiary source available to formulate a recommendation.

ABSTRACT

The significance of Streptococcus intermedius in infectious diseases, especially pleural infections, is gaining recognition. While traditional risk factors like dental procedures and immunosuppression remain pivotal in differential diagnosis, there is an emerging recognition of unconventional clinical presentations and risk factors linked to infections by S. intermedius. This shift compels medical professionals to broaden their diagnostic and therapeutic strategies, underscoring the intricate and evolving nature of managing infections associated with this opportunistic bacterium. We describe the case of a 48-year-old immunocompetent woman with untreated hypertension who experienced a 15-day episode of right-sided chest pain, which worsened with a sudden onset of dyspnea, yet her daily activities remained unaffected. Physical examination suggested a pleuropulmonary syndrome due to significant pleural effusion, with a computed tomography (CT) scan of the lungs revealing about 50% effusion on the right side. Laboratory tests indicated elevated inflammatory markers. Ultrasound-guided thoracentesis extracted purulent fluid compatible with empyema, necessitating the placement of a pleural drain and multiple pleural cavity lavages using alteplase, which led to the removal of substantial infected fluid. Culture of the pleural fluid identified S. intermedius, which was pansusceptible. Treatment with intravenous ceftriaxone was administered, resulting in a favorable clinical outcome. This case highlights the critical nature of recognizing atypical clinical presentations and managing complex bacterial infections in the pleural space.

ABSTRACT

BACKGROUND: Pleural empyema is significant cause of morbidity and mortality. Debate in the literature exists regarding the best initial and definitive therapy, with recent research demonstrating superior short-term outcomes with initial surgical intervention. Despite this, the impact of surgical intervention on long-term outcomes has been incompletely described. A systematic review was undertaken to assess the current evidence evaluating the long-term impact of surgical intervention. METHODS: A systematic review was undertaken according to PRISMA guidelines utilizing three databases. Articles included all papers where patients received surgical intervention for empyema with outcomes evaluated beyond 90 days. Two reviewers extracted and reviewed the articles. Grey literature was included. RESULTS: Eleven studies and two abstracts were extracted. One study and two abstracts evaluated the quality of life outcomes, two studies evaluated dyspnoea outcomes, seven studies evaluated long-term lung function and two studies evaluated mortality and re-admissions. 60-65% of patients had no dyspnoea between 2 and 7 years follow-up. In six of seven studies, normal lung function was achieved in patients with chronic fibrothorax with FEV1% and FVC% improvements between 14-30% and 13-50%, respectively. The results from such biased cohorts could not be extrapolated to conclude that surgical intervention results in better outcomes than ICC drainage. Risk of bias was severe for all 11 studies. CONCLUSION: Surgical intervention potentially improves post-operative lung function, long-term dyspnoea, and mortality. The impact this has on quality of life remains unknown. Future prospective trials with homogenous comparative groups are required to better define the role of surgery and its impact on long-term outcomes.

ABSTRACT

Cholangiocarcinoma of the common bile duct (CBD) presenting as empyema of the gallbladder is a rare entity that poses a risk of septicemia, septic shock, peritonitis, and abscess formation. This case report describes an elderly female presenting with pain in the right hypochondrium, a positive Murphy's sign, and a history of regurgitation and constipation. It highlights the value of imaging in the early diagnosis of this rare presentation of underlying malignancy. The most common cause of empyema of the gallbladder is acute cholecystitis, followed by gallbladder neck obstruction by a calculus. This report discusses the important role of imaging supported by clinical history, examination, laboratory tests, and histopathological findings to diagnose this rare presentation of empyema of the gallbladder as a complication of underlying cholangiocarcinoma. Additionally, it briefly discusses the change in the management line for cholangiocarcinoma patients with complications such as gallbladder perforation and septicemia. The study concludes that the possibility of underlying bile duct malignancy cannot be overlooked in patients with similar symptoms, particularly among the elderly.

ABSTRACT

INTRODUCTION: Pleural effusion is a medical condition where an excessive amount of fluid accumulates in the pleural space. This can be caused by inflammation or malignant growth in the body. Doctors use medical thoracoscopy for both diagnostic and therapeutic purposes. This technique allows them to view the internal pleural surfaces and take biopsies of any abnormal lesions within the pleural cavity. OBJECTIVE: This work aimed to evaluate the diagnostic value of pleuroscopy in patients with undiagnosed exudative pleural effusion. PATIENTS AND METHODS: A study was conducted on 61 patients who had undiagnosed exudative pleural effusion and were admitted to the chest department at the cardiothoracic unit of the Minia University Hospital. All patients provided written consent and underwent a complete history and clinical examination. Standard laboratory tests, including routine liver and kidney function tests, a complete blood count, and a coagulation profile, were conducted on all patients, along with chest X-rays. If necessary, a chest CT scan was also performed. Diagnostic thoracentesis was done, and the pleural fluid was analyzed for sugar, protein, and lactate dehydrogenase and sent for bacteriological analysis (Gram stain, culture, and acid-fast bacilli smear) and cytopathological examination. Medical thoracoscopy was performed in cases where an etiological diagnosis was not established. RESULTS: A total of 61 patients with undiagnosed exudative pleural effusions were included. A definitive etiological diagnosis was reached in 58 (95%) patients. In 47 (77%) of the studied group, malignant etiology was confirmed; nine (14.8%) had tuberculous pleurisy, one (1.6%) had empyema, and one (1.6%) had inflammatory/autoimmune pleurisy. A definite diagnosis was not reached in three (5%) patients. The malignant pathology was caused by bronchogenic carcinoma in 20 (42.5%) cases, malignant mesothelioma in 10 (21.3%) cases, metastatic malignant deposits from other organs in six (12.7%) cases, and lymphoma in three (6.5%) cases. No serious adverse events related to the procedure were recorded. The most common minor complications were transient chest pain in 34 (55.7%) patients, followed by surgical emphysema in 10 (16.4%) patients. CONCLUSION: Pleuroscopy is an effective diagnostic tool for identifying the cause of pleural effusion when it is unclear. It is a minimally invasive and straightforward procedure associated with high diagnostic accuracy and low complication rates.
