Disease at a Glance

Summary
OEIS complex, also known as cloacal exstrophy, is the most severe birth defect within the exstrophy-epispadias complex. It is characterized by Omphalocele, Exstrophy, Imperforate anus and Spinal defects. A child with this condition will have the bladder and a portion of the intestines exposed outside the abdomen with the bony pelvis open like a book. In males, the penis is either flat and short or sometimes split. In females, the clitoris is split and there may be two vaginal openings. Also, frequently the intestine is short and the anus is not open (anus imperforate). There is a high association with other birth defects, especially spina bifida, which occurs in up to 75% of cases. Omphalocele, a defect of the abdominal wall in the region of the umbilicus, is also common, as are kidney abnormalities. The defect occurs when the baby is developing inside the uterus during the first trimester of pregnancy, and seems to be due to the rupture of a tissue known as the cloacal membrane which results in the abnormal development of the abdominal wall and other malformations. The timing of the rupture determines the severity of the disorder. The cause for this malformation is unknown.

Next Steps

Talking with the Medical Team

Good communication between the patient, family, and medical team can lead to an accurate diagnosis. In addition, health care decisions can be made together which improves the patient’s well-being and quality of life.

Describing Symptoms

Describe details about the symptoms. Because there may be many different causes for a single symptom, it is best not to make a conclusion about the diagnosis. The detailed descriptions help the medical provider determine the correct diagnosis.

To help describe a symptom:

  • Use a smartphone or a notebook to record each symptom before the appointment
  • Describe each symptom by answering the following questions:
    • When did the symptom start?
    • How often does it happen?
    • Does anything make it better or worse?
  • Tell the medical team whether any symptoms affect daily activities

Preparing for the First Visit

Working with a medical team to find a diagnosis can be a long process that will require more than one appointment. Make better health decisions by being prepared for the first visit with each member of the medical team.

    Make informed decisions about health care: 
    • Prepare a list of questions and concerns before the appointment
    • List the most important questions first, not all questions may be answered in the first visit
    • Ask questions about symptoms, possible diagnoses, tests, and treatment options
    For future appointments:
    • Discuss what was not addressed at the last visit
    • Discuss changes in the quality of life for the patient, family, and caregivers
    • Discuss health goals and other issues in the patient’s and family’s life that may affect the health care decisions
    Take notes during the appointments to help remember what was discussed.
