Drainage of pediatric lung abscess by cough, catheter, or complete resection
Insights
Pediatric lung abscesses often involve polymicrobial infections and require age-dependent treatment. Younger children (under 7 years) frequently need surgical intervention like catheter drainage or resection for successful recovery.
Area of Science:
- Pediatric Pulmonology
- Infectious Diseases
- Pediatric Surgery
Background:
- Lung abscesses in children can arise from aspiration or bacterial pneumonia.
- Associated conditions include leukemia, immune deficiencies, and prematurity, increasing vulnerability.
- Polymicrobial infections, often aerobic and anaerobic bacteria, are common in pediatric lung abscesses.
Purpose of the Study:
- To evaluate treatment outcomes for pediatric lung abscesses.
- To determine the efficacy of medical versus surgical interventions based on patient age and abscess characteristics.
- To highlight the need for early surgical consideration in specific pediatric populations.
Main Methods:
- Retrospective analysis of eight children (7 weeks to 17 years) treated for lung abscess.
- Assessment of medical management (antibiotics, chest physiotherapy) and surgical interventions (catheter pneumonostomy, wedge resection).
- Correlation of treatment success with patient age, infection type, and abscess location.
Main Results:
- Medical treatment succeeded in 3 older children (10-17 years).
- Five younger children (7 weeks to 7 years) required catheter drainage or resection.
- Pneumonostomy was curative in 3 of 4 cases; resection was necessary for chronic or multiple abscesses.
Conclusions:
- Treatment success for pediatric lung abscess is age-related, with younger children often needing surgical intervention.
- Early and aggressive surgical treatment, including pneumonostomy or resection, may be lifesaving in non-responsive cases.
- Lung abscesses in immunocompromised children pose a significant risk of fatal sepsis, underscoring the need for timely and effective management.
Abstract:
We treated eight children, aged 7 weeks to 17 years, for lung abscess. Each abscess followed an episode of aspiration or a bacterial pneumonia. Associated conditions were leukemia, congenital immune deficiency, endocarditis, cerebral palsy, and prematurity. Seven of the 8 children had polymicrobial infections, usually containing both aerobic and anaerobic bacteria. The success of medical treatment by antibiotics and chest physiotherapy was age related; 3 of the 8 children, aged 10 to 17 years, recovered on this regimen, whereas five children, aged 7 weeks to 7 years, required catheter drainage or resection for cure. Drainage by catheter pneumonostomy was performed for solitary peripheral bacterial abscesses. A large intercostal catheter was inserted into the cavity, either operatively or percutaneously. Wedge resection was performed for multiple, central, or fungal abscesses. Pneumonostomy was curative in 3 of 4 children. One chronic abscess recurred after pneumonostomy and required resection. Wedge resection was curative in the two children who came to thoracotomy; lobectomy was not necessary. Although all eight children recovered from their lung abscesses, three of them died within a year of sepsis. Lung abscess today occurs in immunocompromised children who are vulnerable to fatal infections. Chest physiotherapy is unlikely to achieve good drainage in children under 7 years of age. Medical failures can be identified within the first week of treatment. Early and aggressive surgical treatment is indicated in such children, and may be lifesaving.
