​“OEIS, one of the most severe congenital anomalies compatible with life, occurs in up to 1 in 200,000 to 400,000 live births. The condition affects nearly every major organ system with severe neurologic, skeletal, gastrointestinal, and genitourinary ramifications. Cloacal exstrophy, also known as OEIS Syndrome, occurs when a portion of the large intestine lies outside of the body, and on either side of it —and connected to it — are the two halves of the bladder.”
“In cloacal exstrophy, a baby’s bladder is open in the front and the inner surface is exposed on the lower surface of the abdominal wall. The exposed bladder appears as a right and left half, with the large intestine exposed and connected in the middle. This abnormal connection of the intestine and the bladder allows mixing of stool and urine. Cloacal exstrophy can occur as part of OEIS syndrome, which includes an omphalocele, extrophy, imperforate anus and spinal defects.”
Omphalocele
The omphalocele may be a large protrusion outside the cavity of the abdomen, involving several organs including the spleen, liver and intestine. It may also be small where only a portion of the intestine protrudes from the abdominal cavity. Exstrophy of the bladder and rectum
Development of the bladder In utero is separated into two halves and open. The colon and rectum are also open with a segment of the rectum situated between the halves of the bladder and located on the surface of the abdomen. Imperforate anus
A congenital birth defect, the anus of a new born has not been formed at birth (perforated) and the colon may connect to the urethra, bladder or vagina through a fistula (small tract). Spinal defects
Infants with cloacal exstrophy often are born with further spinal complications including spina bifida.
