Definition / general
- Imperforate mucosal diaphragm or stringlike segment of bowel
- Very rare (1 per 20,000 live births)
- Associated with other congenital anomalies, including Hirschsprung disease
- May have genetic (J Pediatr Surg 2005;40:390) or vascular cause
- Type 1: bowel and mesentery are intact, but bowel lumen is interrupted by a complete membrane
- Type 2: bowel is discontinuous, connected by a fibrous cord
- Type 3: bowel ends are completely separated and mesentery has a gap
