Anorectal Malformation

Full Definition

Anorectal malformations are a spectrum of congenital anomalies where the anal opening and rectum fail to develop properly during fetal development. These conditions range from simple anal stenosis to complex cloacal malformations. Treatment typically involves staged surgical procedures, often beginning in the neonatal period. Editors should note that these are distinct from acquired conditions and require specific terminology when describing surgical approaches and outcomes.

Usage

Usage note: Always specify the type and complexity level of the malformation when known.
