Abstract:
Omphalomesenteric fistula is a complete persistence of the omphalomesenteric duct communicating between the umbilicus and the intestine. The presence of intestinal contents suggests the diagnosis in its typical form. We report a case of omphalomesenteric fistula in a 3-year-old boy to show that intestinal parasitic infection associated with ascariasis expulsion through the umbilicus can be the incidental finding of the omphalomesenteric fistula. This case needs no paraclinical investigation and treatment consists in partial transumbilical resection followed by umbilicus restitution.
Insights
Omphalomesenteric fistula, a rare condition, can present with ascariasis expulsion. Surgical resection is the standard treatment for this umbilical-intestinal connection.
Area of Science:
- Pediatric Surgery
- Gastroenterology
- Congenital Anomalies
Background:
- Omphalomesenteric fistula results from the incomplete obliteration of the omphalomesenteric duct, connecting the umbilicus to the intestine.
- Diagnosis is typically suggested by the discharge of intestinal contents from the umbilicus.
Observation:
- A 3-year-old boy presented with an omphalomesenteric fistula.
- The patient incidentally expelled Ascaris roundworms through the umbilicus.
Findings:
- The case highlights that intestinal parasitic infection, specifically ascariasis, can be an incidental finding in omphalomesenteric fistula.
- No extensive paraclinical investigations were required for diagnosis.
Implications:
- This case broadens the differential diagnosis for umbilical discharge in children.
- Treatment involves surgical correction via partial transumbilical resection and umbilical reconstruction.
