Abdominal wall muscle weakness outcomes after split abdominal flap repair of large congenital diaphragmatic hernias in newborn
Topic overview
This retrospective study of 18 neonates demonstrates that split abdominal wall muscle flap repair for large CDH defects results in transient abdominal wall weakness that resolves spontaneously in 94% of patients by 3 years without requiring intervention. The technique achieved low recurrence rates (5.6%) and no mortality, supporting its use despite theoretical concerns about muscle weakness.
Key takeaways
- Split abdominal wall muscle flap (SAWMF) effectively repairs large CDH defects with only 5.6% recurrence rate in 18 neonates.
- Abdominal wall weakness post-SAWMF is asymptomatic and resolves spontaneously in 67% at 1 year, 94% by 3 years.
- SAWMF is safe for severe CDH cases (78% liver-up, mean LHR 1.49) without requiring surgical correction of muscle weakness.
- No patients required treatment for abdominal wall weakness or died, supporting SAWMF as a viable primary repair technique.
- Muscle weakness manifests as a bulge but does not limit function, making SAWMF concerns about donor-site morbidity unfounded.
