Insights
Parietal pleural clipping is a safe and effective surgical treatment for congenital chylothorax, significantly reducing lymphatic leakage in infants. This minimally invasive technique offers a successful alternative to traditional medical management.
Area of Science:
- Pediatric Surgery
- Thoracic Surgery
- Neonatal Medicine
Background:
- Congenital chylothorax management involves total parenteral nutrition and tube thoracostomy.
- These treatments pose risks of fluid shifts and infection due to leukopenia in infants.
Purpose of the Study:
- To describe the technique of parietal pleural clipping for congenital chylothorax.
- To evaluate its efficacy as a surgical intervention.
Main Methods:
- Retrospective review of medical records for infants diagnosed with chylothorax (January 2002 - April 2014).
- Thoracoscopic parietal pleural clipping performed in six patients due to inability to visualize thoracic duct.
Main Results:
- Parietal pleural clipping dramatically resolved chylous leakage in all six infants.
- Average chest tube output decreased from 86.96 ml/kg/day pre-surgery to 6.5 ml/kg/day on post-op day 2.
- Most surgical patients (5/6) had bilateral disease, successfully treated with clipping.
Conclusions:
- Thoracoscopic parietal pleural clipping is a straightforward, safe, and successful treatment for congenital chylothorax.
- This technique offers a viable surgical option for managing this condition.
Purpose:
Medical management of congenital chylothoraces consists of total parental nutrition and tube thoracostomy. However, these infants are exposed to significant fluid shifts and the related leukopenia carries a high infection risk. The purpose of this review is to describe the technique of parietal pleural clipping as a surgical treatment of congenital chylothorax.
Methods:
The medical records of all patients with a chylothorax diagnosis during the study period of January 2002 to April 2014 were retrospectively reviewed.
Results:
Six of 14 infants identified underwent thoracoscopic parietal pleural clipping to disrupt the pleural lymphatic channel flow as visualization of the thoracic duct and lymphatics was not possible. Nearly all surgical patients had bilateral disease (5/6). Resolution of chylous leakage was dramatic following parietal clipping. In the surgical patients, chest tube output 2 days prior to surgery averaged 86.96 ml/kg/day. After parietal clipping, chest tube output dropped to an average of 6.5 ml/kg/day on post op day 2. Thereafter, chest tube output remained low to negligible and chest tubes were removed variably as enteral feeds were started.
Conclusions:
We describe a straightforward technique of thoracoscopic parietal pleural clipping as a safe and successful option for treatment of congenital chylothoraces.
