Full Definition
OEIS complex is a rare constellation of congenital anomalies characterized by omphalocele, exstrophy of the bladder or cloaca, imperforate anus, and spinal defects. This syndrome represents one of the most challenging conditions in pediatric surgery due to the complexity and severity of the associated malformations. The condition affects multiple organ systems and requires extensive multidisciplinary coordination involving pediatric surgery, urology, orthopedics, and other specialties. Surgical management is staged and highly individualized, with the primary goals being functional reconstruction and optimization of quality of life. The prognosis varies significantly based on the severity of associated anomalies.
