Focused Clinical Observation of Functional Outcomes in Children With OEIS Complex

Area of Science:

• Pediatric Surgery
• Developmental Biology
• Congenital Anomalies

Background:

• Omphalocele, Cloacal Exstrophy, Imperforate Anus, Spinal Defects (OEIS) complex is a rare congenital disorder.
• Limited data exists on the long-term functional and developmental outcomes for individuals with OEIS complex.

Purpose of the Study:

• To evaluate long-term ambulatory, urological, and intellectual outcomes in a cohort of patients diagnosed with OEIS complex.
• To identify factors influencing functional and developmental trajectories in OEIS complex.

Main Methods:

• Retrospective review of 10 patients with OEIS complex treated between 1991 and 2021.
• Assessment of ambulatory status, urinary continence, and intellectual function at the most recent follow-up.
• Radiological or intraoperative classification of spinal defects.

Main Results:

• At a mean follow-up of 114 months, 50% of patients were independently ambulatory, with others requiring orthoses or being nonambulatory.
• Only 2 out of 9 patients achieved urinary continence; 7 remained incontinent.
• Among school-aged patients, 5 attended regular schools, indicating generally favorable intellectual outcomes.

Conclusions:

• Long-term ambulatory and intellectual outcomes in OEIS complex are generally favorable, especially without severe complications.
• Urinary continence remains a persistent challenge requiring ongoing management.
• Multi-institutional, multidisciplinary studies with extended follow-up are crucial due to the rarity of OEIS complex.
