Understanding and managing a case of the omphalocele-exstrophy-imperforate anus-spinal defect complex

The omphalocele-exstrophy-imperforate anus-spinal defects (OEIS) complex is a rare birth disorder involving a combination of gastrointestinal, musculoskeletal, renal, neural, and genitourinary system defects. We present a case report of a neonate with OEIS born by vertex spontaneous delivery to non-consanguineous parents. The major presenting defect was exstrophy of the cecum lying between two exstrophied halves of the bladder, an imperforate anus and spina bifida myelomeningocele. Explorative laparotomy revealed a duplex kidney system, attachment of the terminal ileum and cecum to the exstrophy, and a sausage-like atretic large bowel. Malrotation was also noted. Ladd's bands were released followed by ileostomy and ureterostomy. Patient was stable post-operatively and in the incubator on room air. OEIS remains a challenging anomaly that requires optimal treatment to facilitate the quality of life. With appropriate surgical intervention, the functional and social treatment goals for this unusual congenital defect can be met.
