Thoracotomy patch repair of large diaphragmatic herniae in a porcine model: a tale of two patches
Topic overview
This porcine study compared biologic (Surgisis) versus composite (Parietex) mesh patches for large diaphragmatic hernia repair over 6 months. Parietex demonstrated superior outcomes with no recurrences, better muscle integration, and fewer adhesions, while all failures occurred in the Surgisis group despite similar tensile strength.
Key takeaways
- Parietex composite mesh showed no recurrences or eventrations vs 5 failures with Surgisis biologic patch in large CDH repair (30% defect)
- Parietex demonstrated significantly greater muscle ingrowth and fewer adhesions compared to Surgisis at 6 months post-repair
- Both patches achieved tensile strength equivalent to native diaphragm tissue by 6 months in growing porcine model (6kg→94kg)
- Composite mesh may offer superior outcomes over biologic patch for large diaphragmatic defects requiring patch closure
