Persistent omphalomesenteric duct and urachus presenting as an umbilical hernia.

Area of Science:

• Embryology
• Congenital Malformations
• Surgical Diagnosis

Background:

• Vitellointestinal duct (VIM) anomalies occur in 2-3% of the population, often asymptomatic but can cause complications like bowel obstruction in children.
• Urachal anomalies are rare, typically presenting as cysts or sinuses, with patent urachus being less common.

Observation:

• This report details an adult patient undergoing diagnostic laparoscopy for umbilical hernia repair.
• Intraoperative findings revealed a patent vitellointestinal duct and an urachal anomaly.

Findings:

• The study identified co-existing patent vitellointestinal duct and urachal anomalies in an adult.
• These anomalies were incidentally discovered during surgery for a seemingly unrelated condition.

Implications:

• This case underscores the importance of considering rare congenital anomalies in adult surgical presentations.
• Intraoperative diagnosis through laparoscopy can be crucial for managing complex or unexpected findings.
• Further research may explore the long-term implications and management strategies for such combined anomalies in adults.
