Patch Repair Versus Flap Repair for Congenital Diaphragmatic Hernia: A Systematic Review and Meta-Analysis

jpedsurg.org

Congenital diaphragmatic hernia (CDH) often requires non-primary repair of large defects using either a prosthetic patch or an autologous muscle flap. However, their comparative effectiveness remains uncertain. We systematically reviewed the existing literature to synthesize outcomes relevant to durability and perioperative safety of patch versus flap repair in neonates.

In brief

This systematic review compares prosthetic patch repair versus autologous muscle flap repair for large congenital diaphragmatic hernia defects in neonates. The meta-analysis synthesizes evidence on repair durability and perioperative safety to guide surgical decision-making when primary closure is not feasible.

Large CDH defects require non-primary repair using either prosthetic patch or autologous muscle flap techniques.
Comparative effectiveness data between patch and flap repair methods remains limited and uncertain.
Systematic review focuses on durability and perioperative safety outcomes in neonatal CDH repair.
Choice between patch versus flap repair lacks clear evidence-based guidance for surgeons.
