Synthetic or Biological patch for CDH?
Topic overview
Systematic review comparing synthetic versus biological patches for congenital diaphragmatic hernia repair shows synthetic patches have lower recurrence rates (16.7% vs 30.3%) but higher skeletal deformity risk. Both patch types show similar rates of adhesive bowel obstruction and gastroesophageal reflux complications.
Key takeaways
- Synthetic patches show lower recurrence rates (16.7%) compared to biological patches (30.3%) in CDH repair.
- PTFE patches have 11.5% recurrence vs 33.3% for SIS biological patches at 1-year follow-up.
- Pectus deformity occurs in up to 80% of synthetic patch repairs, a significant long-term complication.
- Adhesive bowel obstruction rates are similar between patch types (4-29% synthetic, 7-35% biological).
- Newer biological patches may perform better than older SIS-based data suggests; consider patch generation when choosing.
