Unusual Ileal Anomalies Associated with Omphalomesenteric Duct Remnants

Area of Science:

• Gastroenterology
• Pediatric Surgery
• Developmental Biology

Background:

• Omphalomesenteric duct (OMD) remnants are congenital anomalies resulting from incomplete obliteration of the omphalomesenteric duct.
• These remnants frequently present with gastrointestinal malformations, most commonly Meckel's diverticulum.
• Understanding the spectrum of associated anomalies is crucial for effective surgical management.

Observation:

• This report details two previously undocumented anomalies associated with OMD remnants: ileal stenosis and ileal duplication.
• These findings expand the known spectrum of congenital abnormalities linked to OMD remnants.
• The cases underscore the variability in presentations of OMD remnant-associated malformations.

Findings:

• The study identifies ileal stenosis and ileal duplication as rare, previously unreported malformations associated with omphalomesenteric duct remnants.
• This expands the differential diagnosis for patients presenting with OMD remnants and concurrent digestive tract abnormalities.
• The findings emphasize that the association between OMD remnants and digestive anomalies is broader than previously recognized.

Implications:

• Surgeons managing patients with omphalomesenteric duct remnants must maintain a high index of suspicion for associated, potentially rare, digestive tract malformations.
• Awareness of these associated anomalies is critical to prevent diagnostic delays and ensure comprehensive surgical planning.
• Early recognition and appropriate management of these combined anomalies can significantly reduce the risk of postoperative complications and improve patient outcomes.
