The omphalomesenteric duct cyst is a rare congenital condition resulting from the incomplete obliteration of the omphalomesenteric duct, also known as the vitelline duct. This duct is an embryonic structure that connects the yolk sac to the midgut of the developing fetus. Normally, it obliterates during the 5th to 9th week of gestation. However, if it persists, it can lead to various anomalies, including the formation of a cyst.

Presentation

Patients with an omphalomesenteric duct cyst may present with abdominal pain, a palpable abdominal mass, or signs of intestinal obstruction. In some cases, the cyst may become infected, leading to additional symptoms such as fever and tenderness.

Diagnosis

The diagnosis of an omphalomesenteric duct cyst is typically made using imaging studies. An ultrasound can reveal a cystic structure in the abdomen, while a CT scan provides more detailed information about its size and location. These imaging modalities help differentiate the cyst from other potential causes of abdominal masses in children.

Treatment

The definitive treatment for an omphalomesenteric duct cyst is surgical excision. This procedure involves the removal of the cyst and any associated fibrous bands or remnants of the duct. Surgery is usually curative, and the prognosis is excellent if the cyst is completely excised.

Complications

If left untreated, an omphalomesenteric duct cyst can lead to complications such as infection or bowel obstruction. In rare cases, it may be associated with other anomalies like Meckel's diverticulum, which can also cause gastrointestinal bleeding or obstruction.
