Pleural space disease in pediatric patients: a retrospective analysis

Pleural space disease, pleural effusions, and parapneumonic empyema present a therapeutic dilemma regarding the most appropriate medical and surgical management (i.e., performing a thoracentesis on admission versus delayed, placing a pigtail catheter versus a regular chest tube, and performing early versus late thoracoscopy). Other questions remain about early surgical intervention to decrease morbidity, shorten hospital stay, and produce cost-effective results. To define a clinical approach for a prospective study, the charts of all patients who were discharged with ICD-9 codes 511.8, 511.9, and 510.9, between June 5, 1991, and May 7, 1995, were reviewed. Thirty-one patients were identified. A database was developed and the results were analyzed. This paper presents a clinical pathway suggested by this retrospective study with cost analysis.

The use of a Dumon stent for the treatment of a bronchopleural fistula

We report the successful management of a bronchopleural fistula with bronchial stent placement combined with irrigation of the empyema cavity. A bronchopleural fistula occurred in a 67-year-old man after a right upper lobectomy for lung cancer. Resuturing of the bronchial stump plus omental wrapping and subsequent closure of the open stump with a pedicled flap of intercostal muscle were not effective. Consequently, we placed a Dumon stent in the right main bronchus to close the stump.

Pulmonary nocardiosis associated with idiopathic thrombocytopenic purpura

A 69-year-old woman with idiopathic thrombocytopenic purpura, who was regularly followed and treated with prednisolone and danazol, was admitted to our hospital because of shortness of breath. Chest roentgenogram showed a large amount of left-sided pleural effusion. Gram-positive branching rods, subsequently identified as Nocardia farcinica, were isolated from the fluid. Antibiotic treatment together with pleural drainage with an intercostal catheter resulted in complete remission of pyothorax. Pulmonary nocardiosis is a rare disease, but recognition of the disease in immunocompromised patients and the prompt initiation of appropriate treatments based on isolation of the pathogen can lead to a successful outcome.

Optimal management of complicated empyema

BACKGROUND

Despite continued improvement in medical therapy, empyema remains a challenging problem for the surgeon. Multiple treatment options are available; however, the optimal therapeutic management has not been elucidated.

METHODS

A retrospective review was performed of all adult patients admitted to Denver Health Medical Center between January 1, 1993, and December 31, 1998, with the diagnosis of empyema. Data tabulated included patient demographics, presentation, chest computed tomography (CT) findings, treatment, and outcome.

RESULTS

Empyema was diagnosed in 58 patients, 45 cases of which were multiloculated at the time of presentation. Empyema was secondary to pneumonia is 41 patients and posttraumatic in 15. In addition to antibiotic therapy, initial treatment included chest tube drainage alone (n = 6), chest tube drainage with primary operation (n = 19), and chest tube drainage with intrapleural fibrinolytic therapy (n = 33). In 15 patients (45%), fibrinolytic therapy failed. Initial chest CT revealed a pleural peel in 5 patients treated with fibrinolytics and all failed. Multiloculation, however, was not a factor in failure of fibrinolysis. Moreover, chest CT missed the presence of a pleural peel in 17 of 31 patients documented to have a significant peel at the time of thoracotomy.

CONCLUSION

Multiple therapeutic options are available for the management of empyema. Multiloculation is not a contraindication to an initial trial of chest tube drainage or fibrinolytic therapy. In contrast, CT evidence of a pleural peel uniformly predicted failure of nonoperative treatment.

Sonographic septation: a useful prognostic indicator of acute thoracic empyema

The aim of this study was to identify sonographic predictors of patient outcomes or need for surgical intervention of acute thoracic empyema. All patients with a clinical diagnosis of thoracic empyema underwent transthoracic ultrasonographic examination and thoracentesis at admission. According to the presence or absence of septa in sonographic images, the patients were classified into two groups: septated and nonseptated. Sonographic findings were analyzed with respect to duration of hospital stay, chest tube drainage, and treatment efficacy. A total of 163 consecutive patients were included in the study (83 patients with septated and 80 with nonseptated sonographic images). The mean duration of hospital stay (35.4 versus 27.0 days, P = 0.009) and chest tube drainage (13.1 versus 7.6 days, P < 0.001) for the patients with septa were significantly longer than for those without septa. The patients with septa were more likely to undergo intrapleural fibrinolytic therapy (63.8% versus 38.8%, odds ratio 2.79, P = 0.001) and surgical intervention (24.3% versus 7.5%, odds ratio 3.92, P = 0.004). We concluded that sonographic septation is a useful sign to predict the need for subsequent intrapleural fibrinolytic therapy and surgical intervention in cases of acute thoracic empyema. Early fibrinolytic therapy or even surgical intervention may be indicated in patients with sonographic septations.

Paediatric thoracic empyema in an Ethiopian referral hospital

OBJECTIVES

To analyse underlying conditions, clinical manifestations, aetiologic agents and management of empyema thoracis and to determine the outcome of the disease.

DESIGN

A retrospective study.

SETTING

Ethio-Swedish Children's Central referral (teaching) Hospital, Addis Ababa, Ethiopia.

SUBJECTS

Thirty eight patients with a discharge diagnosis of non-tuberculous thoracic empyema seen from January 1988 to December 1992.

RESULTS

The incidence was 2.7/1000 admissions, which is higher than that reported elsewhere. Sixty six per cent of the patients were under five. Pneumonia was the antecedent illness in almost all cases. Fever, dyspnoea and signs of respiratory distress and effusion were the commonest presenting features. Bacteriological examination revealed Staphylococcus aureus as the commonest aetiologic agent (58%). All patients were treated with antibiotics, and drainage of the empyema was effected by closed thoracostomy in 71% of the cases, while the rest were managed with thoracentesis alone. The case fatality rate was 16%. A long hospital stay and high rate of complications were also observed.

CONCLUSION

Empyema is not rare in our practice. Early diagnosis and proper treatment of pneumonia prevents the development of empyema. Therefore, establishing an efficient management protocol that is relevant to our particular set up is required.

Managing the nonsurgical candidate with an empyema related to community-acquired lobar pneumonia

This case study reviews the medical management for a 76-year-old patient with a cardiac history and recurrent admissions for a persistent pneumonia. Computed tomography showed evidence of an empyema in the right middle and lower lobes of his lung. The standard treatment for an empyema is a thoracotomy and long-term antibiotics. However, the patient's cardiac history disqualified surgery as an option. Therefore the management plan was composed of antibiotics and treatment of his symptoms. The patient's symptoms improved after a week of levofloxacin (Levaquin), prednisone, bilevel positive airway pressure mask as required, and oxygen. He was discharged with home care, oxygen, Levaquin, tapering doses of prednisone, and previous medications. At a 6-week follow-up examination, the patient was asymptomatic and had marked improvement noted on chest radiograph. The advanced practice nurse played an important role in this patient's recovery by conducting patient education and coordinating follow-up after his release.

[Staphylococcus aureus purulent pleurisy in children. Experience of the Albert Royer Hospital for Children of the Fann University Hospital Center in Dakar]

The authors report here by a retrospective study 58 cases of Staphylococcus aureus empyema at Albert ROYER child hospital located in the Fann University Teaching Hospital of Fann between January 1st 1992 and December 31, 1995. In this study staphylococcus aureus is the bacterium involved in pleural effusions of the children (54%) a long way ahead Streptococcus pneumoniae (16%). Infant less than 30 month is more affected (86%). The average age of the patients is 16.8 month +/- 16.6. The resistance of the germ to usual antibiotics, the precariousness of the research field and mechanical complications linked to the outpouring explain their seriousness. The treatment lies upon an adapted antibiotic and bactericidal therapy associated to closed chest tube drainage.

Computed tomography or ultrasonically guided pigtail catheter drainage in multiloculated pleural empyema: a recommended procedure?

OBJECTIVES

The role of image-guided pigtail catheter drainage in the treatment of pleural empyema is associated with different outcomes, dependent on the stage of the disease. No agreement concerning its use exists.

METHODOLOGY

Fourteen patients at a fibropurulent stage of pleural empyema initially treated with computed tomography (CT) or ultrasonically guided pigtail catheter drainage were reviewed. All patients were admitted with clinical symptoms of sepsis. Chest X-ray, CT scan and/or ultrasonography and thoracentesis with biochemical examination revealed multiloculated pleural empyema. Despite the diagnosis of multiloculated empyema, CT or ultrasonically guided pigtail catheter drainage was performed. However, septic symptoms deteriorated and all cases proceeded to thoracotomy with decortication.

RESULTS

Image-guided drainage failed in all patients. Septic symptoms disappeared within 24-48 h after decortication. The patients recovered without sequela, were discharged 6-15 days (mean: 9.2 days) postoperatively and were able to return to normal physical activity.

CONCLUSIONS

Computed tomography or ultrasonically guided pigtail catheter drainage can not be recommended in the case of a fibropurulent stage of empyema thoracis.

A 10-year experience with bacteriology of acute thoracic empyema: emphasis on Klebsiella pneumoniae in patients with diabetes mellitus

STUDY OBJECTIVES

To provide an updated evaluation of the bacteriology of acute thoracic empyema for more efficacious treatment.

DESIGN

: The medical and microbiological records of all patients who received a diagnosis of acute thoracic empyema were reviewed. Based on the bacteria isolated from the pleural fluid, the patients were classified into the following four groups: aerobic or facultative Gram-positive; aerobic Gram-negative; anaerobic; and mixed.

SETTING

A university-affiliated tertiary medical center.

PATIENTS AND METHODS

From January 1989 to December 1998, 171 patients with a diagnosis of acute thoracic empyema were treated. A comparative analysis of the isolates from pleural effusions, the mean length of hospital stay, the mean duration of chest tube drainage, the mean duration between the onset of symptoms and the establishment of diagnosis, treatment efficacy, and the need for subsequent intervention was performed.

RESULTS

A total of 163 microorganisms were isolated from the pleural fluid of 139 patients. These patients were classified according to the following types of isolates: aerobic or facultative Gram-positive (n = 47); aerobic Gram-negative (n = 59); anaerobic (n = 14); and mixed (n = 19). Klebsiella pneumoniae was the most commonly isolated pathogen (24. 4%) and was strongly associated with a diagnosis of diabetes mellitus. The mortality rate of patients with aerobic Gram-negative bacilli isolated was the highest (22.0%), followed by those with mixed pathogens isolated (15.7%), aerobic or facultative Gram-positive (6.4%), and anaerobic (0%).

CONCLUSIONS

The increasing incidence of acute thoracic empyema caused by Gram-negative bacilli, especially by K pneumoniae, has become an increasing problem. The isolation of aerobic Gram-negative bacilli or multiple pathogens from pleural fluid is associated with a poor prognosis and indicates a need for more aggressive antimicrobial chemotherapy.

Fungal empyema thoracis: an emerging clinical entity

STUDY OBJECTIVES

To analyze the clinical spectra, pathogenesis, treatment, outcome, and prognostic factors of fungal empyema thoracis.

DESIGN

The medical records of patients with positive fungal cultures from pleural effusions were retrospectively analyzed.

SETTING

A university-based tertiary care hospital in Taipei, Taiwan.

PATIENTS AND METHODS

From January 1990 through December 1997, patients diagnosed with fungal empyema were included in this study. The criteria for diagnosis of fungal empyema thoracis were as follows: (1) isolation of a fungal species from the pleural effusion; (2) significant signs of infection, such as fever (body temperature > 38.3 degrees C) and leukocytosis (white blood cell > 10,000/microL); and (3) isolation of the same mold species from pleural effusion on more than one occasion, or from pleural effusion and other specimens such as blood, sputum, or surgical wounds that showed evidence of tissue invasion.

RESULTS

Sixty-seven patients with fungal empyema thoracis were included. Their mean age was 54 years (range, 2 weeks to 93 years), and 64% (43 patients) were men. Fifty-seven patients (85%) had various underlying diseases, and 18 (27%) had more than one immunocompromising condition. A total of 73 fungal isolates were recovered from pleural effusion; the most commonly encountered were Candida species (47 isolates, 64%), Torulopsis glabrata (13 isolates, 18%), and Aspergillus species (9 isolates, 12%). Candida albicans (28 isolates) was the most common Candida species, followed by Candida tropicalis (13 isolates). Six patients (9%) had two fungal strains isolated, and 16 (24%) had concomitant bacterial empyema thoracis. Eighteen patients (27%) had concurrent fungemia. Most (56 patients, 84%) cases of fungal empyema thoracis were nosocomial, and many case (43 patients, 64%) were acquired in ICUs. Abdominal disease (20 patients, 30%), especially previous abdominal surgery and GI perforation (12% and 10%, respectively), was the most common cause of fungal empyema thoracis, followed by bronchopulmonary infection (15 patients, 22%) and chest surgery (12 patients, 18%). Forty-nine patients (73%) received systemic antifungal therapy, and 38 (57%) underwent closed drainage therapy. Eleven patients (16%) underwent pleural irrigation with normal saline solution, povidone-iodine solution, or antifungal agents. Six patients (9%) finally received decortication. All patients receiving surgery or pleural irrigation with antifungal agents survived. Despite the aforementioned management, the crude mortality was high (73%). Multivariate analysis showed a significantly increased risk of death in immunocompromised patients (relative risk, 1.58; p < 0.005) and those with respiratory failure (relative risk, 2.31; p < 0.001). Systemic antifungal therapy was associated with a significantly lower risk of death (relative risk, 0.69; p < 0.05).

CONCLUSION

These data imply an increasing incidence of fungal empyema thoracis in recent years and the necessity for aggressive treatment of patients with this disease.

Pyogenic lung infections: factors for predicting clinical outcome of lung abscess and thoracic empyema

Lung abscess and thoracic empyema continue to cause significant morbidity and mortality despite appropriate antibiotic therapy and various options for drainage of empyema. Multiple factors, including the patient's general state of health, the presence of underlying disease, the virulence of the pathogen responsible, and the promptness of drainage of empyema, appear to dictate the clinical outcome. However, the available data are derived from uncontrolled, retrospective studies and the high morbidity and mortality rates underscore the need for large prospective studies to better evaluate factors that may predict the clinical outcome of these conditions.

Inhalation of wild barley into the airways: two different outcomes

OBJECTIVE

There are only two previous reports of wild barley inhalation into the tracheobronchial tree in the literature. Our aim is to describe the effects, outcome and management of wild barely inhalation into the airways.

METHODS

In a retrospective study, 18 patients with inhalation of spike of wild barley into the tracheobronchial tree were divided into 2 groups according to their clinical presentation.

RESULTS

Eighteen children below 5 years of age presented between 1989 and 1994 inclusive. Fourteen patients presented with a short duration of choking and cough. The wild barley spike was removed by laryngoscopy (12 patients) or rigid bronchoscopy (2 patients). Four patients presented with a longer history of cough, dyspnea and fever and had serious respiratory disease such as pneumothorax, lobar pneumonia and pleural empyema requiring surgical intervention. All patients made a satisfactory recovery.

CONCLUSION

Wild barley is a common grass in our area and we should be aware that children are exposed to the risk of inhalation into the airways.

Evolving experience in the management of empyema thoracis

The optimal management of paediatric empyema thoracis remains controversial. The objective of the study was to analyse evolving experience in clinical presentation, management, outcome and factors contributing to adverse morbidity in thoracic empyema. Forty-seven patients presenting to a paediatric surgical centre were studied in three consecutive 6-y periods during 1980-97 to compare any change in the pattern of disease influencing diagnosis and management. Patients were categorized into two treatment groups: (i) conservative management (antibiotics and/or tube thoracostomy), (ii) thoracotomy. The median duration of illness prior to hospital admission was 10 d (range 1-42 d). Ultrasound was increasingly utilized in the diagnosis and staging of empyema and played an important role in directing definitive management. The presence of loculated pleural fluid determined the need for thoracotomy. Sixteen of 20 patients (80%) who were initially treated with thoracocentesis or tube thoracostomy eventually needed thoracotomy. There was a positive shift in management towards early thoracotomy resulting in prompt symptomatic recovery. Significant complications were noted in seven children who had delayed thoracotomy. These included recurrent empyema with lung abscess (n = 2), scoliosis (n = 2), restrictive lung disease (n = 1), bronchopleural fistula (n = 1) and sympathetic pericardial effusion (n = 1). An unfavourable experience with delayed thoracotomy during the study period has led us to adopt a more aggressive early operative approach to empyema thoracis. The decision to undertake thoracotomy has been influenced by the ultrasound findings of organized loculated pleural fluid. Delayed surgery was associated with adverse outcome. Whilst fibrinolytics and thoracoscopy may provide attractive options for early empyema, thoracotomy can hasten patient recovery regardless of the stage of disease. Prospective randomized trials are required to assess the ideal therapy for childhood empyema.

Is there a place for thoracoscopic debridement in the treatment of empyema in children?

BACKGROUND

Video-assisted thoracoscopic debridement has been shown to be a safe and efficient procedure for empyema in the adult patient. Its place in the management of childhood empyema remains controversial.

METHODS

Over an 18-month period, 9 children were operated upon for pleural empyema. All children were initially treated with appropriate antibiotics and chest-tube drainage. Indication for surgery were persistent clinical symptoms and loculation of pleural fluid 5 to 7 days following initial treatment. In case of a duration of the illness of less than 14 days, an initial attempt was made to debride the pleural space by thoracoscopy.

RESULTS

Mean duration of the illness prior to surgery was 15 days (range: 10-23 days), and mean duration of preoperative conservative treatment 10 days (range: 5-20 days). In five of the nine patients thoracoscopy was performed. In all patients thoracoscopy failed to provide adequate clearance of the diseased pleural space because of the advanced stage of the disease. The procedure was converted to a formal thoracotomy in four patients, the fifth patient continued to deteriorate and required formal thoracotomy and decortication seven days later.

CONCLUSION

This limited experience suggests that, with the current management and indications, video-assisted thoracoscopic surgery adds little benefit to the treatment of childhood empyema.

Descending necrotizing mediastinitis with sternocostoclavicular osteomyelitis and partial thoracic empyema: report of a case

We present herein the case of a 50-year-old woman in whom descending necrotizing mediastinitis originating from an anterior neck abscess spread to the left upper bony thorax, resulting in osteomyelitis of the left sternocostoclavicular articulation and left partial thoracic empyema. Transcervical mediastinal irrigation and drainage was performed with aggressive antibiotic therapy, followed by resection of the left sternocostoclavicular joint and debridement of the anterior mediastinum. The patient had an uneventful postoperative course, and her left arm and shoulder mobility was well preserved.

Lack of mediastinal shift as a clue to delayed postpneumonectomy empyema

Delayed postpneumonectomy empyema is uncommon. The condition is usually elusive and diagnosed late in the course of the disease, leading to increased morbidity. New air-fluid level on chest x-ray film or appearance of empyema necessitatis may enhance the index of suspicion and lead to early diagnosis, but in many cases no clinical or laboratory clues are apparent. We describe the case of a 60-year-old man with high fever and dyspnea 3(1/2) years after pneumonectomy. Diagnosis of postpneumonectomy empyema was delayed and finally suggested by the lack of expected mediastinal shift on chest film. Computed tomography (CT) of the chest showed a large quantity of fluid, which later proved to be empyema. The patient was treated successfully by continuous cavity irrigation with neomycin and systemic antibiotics. We conclude that in postpneumonectomy patients with septic fever, the only clue to diagnosis of delayed postpneumonectomy empyema may be hemithorax opacification without mediastinal shift, confirmed by CT-guided thoracocentesis. Therapy with cavity irrigation and systemic antibiotics seems appropriate.
