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.
