Insights
Thoracoscopic surgery for pediatric empyema is safe and effective, significantly reducing the need for thoracotomy after a learning period. While reoperation rates may increase, especially with necrotizing pneumonia, thoracoscopy offers a viable treatment.
Area of Science:
- Pediatric surgery
- Thoracic surgery
- Infectious diseases
Background:
- Empyema treatment in children is evolving.
- Thoracoscopy is increasingly adopted for pediatric empyema management.
- Assessing the feasibility, efficacy, and safety of thoracoscopy in children is crucial.
Purpose of the Study:
- To evaluate the feasibility, efficacy, and safety of thoracoscopy for pediatric empyema.
- To compare outcomes before and after a learning curve for thoracoscopic empyema treatment.
- To determine the rate of thoracotomy avoidance and reintervention.
Main Methods:
- Retrospective review of clinical files for 91 children undergoing primary thoracoscopy for empyema (2006-2014).
- Analysis of demographic, clinical, and surgical data.
- Comparison of outcomes between pre-learning curve (period 1) and post-learning curve (period 2) periods.
Main Results:
- Thoracoscopy was performed in 91 children (median age 4 years).
- Conversion to thoracotomy decreased from period 1 to period 2 (62% vs. 92% avoidance, p=0.001).
- Reoperation was needed in 6.6% of cases, with necrotizing pneumonia associated with higher reintervention risk.
Conclusions:
- Thoracoscopic approach for pediatric empyema is feasible and safe, significantly reducing thoracotomies post-learning curve.
- While reintervention rates may increase, thoracoscopy is effective in most cases.
- Necrotizing pneumonia is a potential contraindication and associated with higher reintervention risk.
Introduction:
Thoracoscopy is increasingly being used in the treatment of empyema. This study assesses feasibility, efficacy and safety in children.
Material And Methods:
Clinical files of patients who underwent primary thoracoscopy for empyema between 2006 and 2014 were reviewed. Demographic, clinical and surgical data were analyzed and a comparison between the period before (period1) and after (period2) the learning curve was performed.
Results:
Ninety-one patients (53 males, 58%) were submitted to thoracoscopy at a median age of 4 years. There were 19 conversions to thoracotomy with a steady decrease of conversion rate until 2009 (period1) and no conversions thereafter (period2). There was no difference in any of the analyzed parameters between patients submitted to thoracoscopy alone and those requiring conversion in period1. Six cases (6.6%) needed redo-operation (five in period2) and thoracotomy was the elected approach in four. Necrotizing pneumonia was present in 60% of the reoperated cases; in other words, in period2 3 out of 9 cases with necrotizing pneumonia required reintervention (p=0.07). Thoracotomy was avoided in sixty-eight (75%) patients (62% in period1 versus 92% in period2, p=0.001).
Discussion And Conclusions:
Thoracoscopic approach for empyema is feasible and safe avoiding a significant number of thoracotomies after a short learning curve. An increase of reintervention rate should be expected, but throracoscopy alone is effective in the great majority of the cases. Necrotizing pneumonia may be associated with a higher risk of reintervention, as it is a contra-indication to thoracoscopy and probably surgery.
