Cloacal exstrophy (CE) represents one of the most complex congenital anomalies encountered in pediatric surgery. This rare condition, occurring in approximately 1 in 200,000-400,000 live births, presents significant challenges for both medical teams and families. This comprehensive review explores current understanding, management approaches, and recent advances in treatment.
Understanding Cloacal Exstrophy
Embryological Basis
- Failed fusion of lateral folds during weeks 4-8 of gestation
- Association with OEIS complex (Omphalocele, Exstrophy, Imperforate anus, Spinal defects)
- Impact on multiple organ systems
Clinical Presentation
Anatomical Features
- Exposed bladder halves
- Separated pubic bones
- Central cecal plate
- Omphalocele
- Spinal dysraphism
Associated Anomalies
- Gastrointestinal malformations
- Spinal cord abnormalities
- Renal anomalies
- Genital anomalies
Prenatal Diagnosis and Planning
Diagnostic Modalities
Ultrasound Markers
