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

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.
